Simulation of International Logistics Costs – Anticipate Variations

Does your operation depend on international trade? Learn how to simulate your logistics costs and anticipate changes in rates, routes, and transit times.

Why simulate logistics costs in global operations?

Global operations are exposed to multiple changing variables that directly impact international logistics costs. From tariff rates to port delays or freight price fluctuations, anticipating these elements enables better decision-making and avoids significant budget deviations.

Logistics simulation becomes a key tool for visualizing these scenarios before they occur. It allows companies to test routes, suppliers, consolidation schemes, and modal alternatives without incurring real costs. For businesses that frequently import or export, this predictive capability can make a difference in profitability and compliance.

Main variables that impact international costs

Simulating means correctly identifying the critical variables that may affect costs. Below are the most relevant ones in international contexts:

Tariffs and trade restrictions

Bilateral trade agreements, customs policies, and legislative changes directly affect import/export duties. Simulations allow for the analysis of different scenarios: for example, what happens if the rules for preferential origin change, or if a new specific tax is applied to a particular product.

In addition, embargoes or temporary sanitary restrictions can influence total logistics operation costs, affecting both timing and penalties.

Freight, insurance, and handling fluctuations

Ocean and air freight rates can fluctuate sharply due to global demand, geopolitical crises, port congestion, or seasonality. The same goes for insurance, consolidation costs, port charges, and handling fees.

Modeling different behaviors of these variables helps understand the possible impact range and prepare mitigation strategies (e.g., long-term contracts or contingency logistics schemes).

Hidden costs due to delays or lack of coordination

Often, the highest costs don’t come from official tariffs but from operational deviations: delays due to incorrect documentation, unnecessary customs storage, lack of synchronization among suppliers, etc.

These situations create hidden costs that can be detected in advance through end-to-end logistics process simulations, helping identify bottlenecks or systemic risks in the operation.

How to build an effective simulation model

The value of a simulation largely depends on how the model is built. To accurately represent an international logistics operation, it’s essential to integrate real data and capture uncertainty precisely.

Input data from real systems

Integrating data from ERP, WMS, TMS, or customs platforms allows the model to more accurately reflect current operating conditions. This includes:

  • Historical import/export volumes
  • Average border crossing or customs clearance times
  • Specific rates by item, route, and supplier

Good integration prevents the model from becoming outdated or overly reliant on theoretical assumptions.

Use of statistical distributions for uncertain processes

International logistics processes are full of uncertainty: shipment durations, container availability, customs inspections, etc. Using statistical distributions instead of fixed values captures this variability and allows for more realistic scenario simulations.

This not only improves simulation accuracy but also enables risk and sensitivity analysis based on the results.

Dynamic visualization and scenario analysis

Effective models don’t just calculate — they communicate. Incorporating interactive dashboards, logistics maps, and scenario comparisons makes it easier for management and non-technical areas to make decisions.

It also enables the simulation of multiple scenarios in parallel: what happens if a supplier changes, if the logistics network is reconfigured, or if a nearshoring strategy is implemented?

Benefits of anticipating logistics deviations before execution

Implementing an international logistics simulation model offers tangible benefits:

  • Reduced operating costs by avoiding miscoordination and unplanned overruns
  • Greater negotiation power with suppliers and logistics operators by better understanding real margins
  • Resilience in disruptive scenarios, with alternative routes and configurations already evaluated
  • Agility to respond to regulatory or tariff changes without halting operations

In short, simulation doesn’t replace experience — it enhances it with data, visualization, and foresight.

Use cases for cost simulation in imports/exports

Companies in various sectors are using this approach to optimize their international operations. Some examples include:

  • Electronics component importers: simulate combined routes and consolidations to minimize the impact of air freight.
  • Agro-industrial exporters: model different combinations of ports, operators, and brokers to maximize efficiency during harvest seasons.
  • Retail multinationals: evaluate the impact of new trade agreements and tariff restrictions on their supply network.

Each case allows decision-making to be validated before execution, reducing high-cost errors.

Recommendations for scaling models in complex operations

When operations become larger or more diverse, scaling the simulation model is also possible, but it requires certain considerations:

  • Use professional simulation platforms that support large data volumes and multiple nodes
  • Modularize the model to simulate regions or products separately
  • Incorporate optimization algorithms that combine simulation with ideal configuration search
  • Automate data updates from internal systems and external sources

In this way, simulation becomes a living tool — evolving with the business and continuously delivering strategic value.

Nearshoring: How It Affects the Supply Chain and How to Anticipate It with Predictive Models

The global supply chain is undergoing an unprecedented transformation. Nearshoring—a strategy that seemed marginal a decade ago—has become the centerpiece of today’s most critical business decisions. The disruptions caused by the COVID-19 pandemic, geopolitical tensions between the United States and China, and rising logistics costs have prompted companies to radically rethink their sourcing approach.

This migration toward geographically closer suppliers is not just a reactive response to crises but a proactive strategy that is redefining the fundamentals of supply chain management. However, successfully implementing nearshoring requires more than good intentions: it demands sophisticated predictive models that help anticipate and mitigate the risks inherent in this transition.

What Is Nearshoring and Why Is It Being Adopted?

Nearshoring refers to the relocation of production or service operations from distant locations to countries or regions geographically closer to the target market. Unlike traditional offshoring, which focused solely on cost reduction by relocating to low-wage countries, nearshoring seeks a balance between cost efficiency, geographic proximity, and risk mitigation.

This strategy has gained relevance due to structural factors that have transformed the global business landscape. The U.S.-China trade war increased tariffs and regulatory uncertainty, making Chinese manufacturing less attractive for the U.S. market. Simultaneously, the pandemic exposed the fragility of overly long supply chains reliant on a single region or provider.

Maritime transport costs—which remained relatively stable for decades—soared dramatically by 300% to 500% on some routes during 2021 and 2022. This volatility eroded the traditional competitive advantages of Asian offshoring. Meanwhile, wages in China have risen significantly, reducing the labor cost gap with other regions.

Time has also become a critical factor. Consumers expect faster deliveries, and companies seek more agility to respond to demand changes. A product manufactured in Mexico can reach the U.S. market in days, whereas from Asia it can take weeks. This time difference translates into tangible competitive advantages in increasingly dynamic markets.

Additionally, sustainability and corporate social responsibility considerations have gained importance. Shorter supply chains generally mean lower carbon emissions from transportation, and geographic proximity makes it easier to monitor labor and environmental standards.

Structural Changes to the Supply Chain

The shift toward nearshoring is not simply a matter of changing supplier locations. It involves a fundamental reconfiguration of the supply chain’s architecture, with ramifications spanning from strategic planning to day-to-day operational execution.

Redesigning Logistics Nodes

Nearshoring forces companies to completely redesign their distribution and storage networks. Distribution centers optimized to receive large volumes from Asia via maritime transport may not be suitable for more frequent, smaller-volume shipments from nearby locations.

This transformation requires significant investment in new logistics infrastructure. Companies must establish or expand regional distribution centers, develop new overland transport routes, and reorganize cross-docking operations. The placement of these new nodes must account not only for proximity to final markets but also for connectivity with new nearshore suppliers.

Warehouse management systems (WMS) and enterprise resource planning (ERP) systems must adapt to different flow patterns. While traditional offshoring managed large batches at low frequencies, nearshoring favors more frequent, smaller deliveries, demanding greater flexibility in management systems.

Changes in Lead Times and Stock Levels

Reduced delivery times are one of nearshoring’s most tangible benefits—but this improvement entails complex adjustments to inventory management. Shorter lead times allow for lower safety stock levels, freeing up working capital that can be reinvested elsewhere in the business.

However, the transition is not automatic. Demand planners must recalibrate their forecasting models to take advantage of the supply chain’s greater responsiveness. Automated replenishment algorithms require adjusted reorder point and economic order quantity parameters.

Lead time variability also changes. Maritime transport from Asia involves high variability due to port congestion, weather, and other factors, whereas overland transport from nearshore locations tends to be more predictable—though it may face disruptions such as border blockades or trucker strikes.

Relocating Critical Suppliers

Nearshoring involves identifying and developing new suppliers in geographically closer regions—a process that may take years and require substantial investment in audits, certifications, and capacity building.

Diversifying suppliers becomes more complex when geographic proximity is a priority. Companies must balance regional risk concentration with operational efficiency. Having multiple suppliers in the same nearshore region reduces coordination costs but increases exposure to regional shocks such as natural disasters or political crises.

Developing nearshore suppliers often requires technology transfer, specialized training, and financing. Companies leading this transition invest in strengthening their new partners—an effort that can yield sustainable competitive advantages but requires long-term commitment.

How to Anticipate the Impact with Predictive Models

The shift toward nearshoring presents significant uncertainties that can be mitigated through the strategic use of advanced predictive models. These tools allow companies to simulate different scenarios, quantify risks, and optimize decisions in a highly complex environment.

Advanced Forecasting of Demand and Capacity

Modern predictive models go beyond traditional time-series forecasting. They integrate multiple data sources—including economic indicators, consumption patterns, seasonal events, and real-time market signals—to generate more accurate demand projections.

In the context of nearshoring, these models must account for different regional market dynamics. Demand in the U.S. may show seasonal patterns that differ from those in Europe or Latin America, and nearshore suppliers must be ready to accommodate these variations. Machine learning algorithms can uncover complex correlations between regional economic variables and specific demand patterns.

Predicting the capacity of nearshore suppliers presents unique challenges. Many are still in the process of expanding or transforming, introducing volatility in productive capacity. Predictive models can incorporate leading indicators such as equipment investment, hiring trends, and expansion projects to anticipate changes in available capacity.

Scenario Modeling Under Uncertainty

Monte Carlo simulation and other stochastic modeling methods allow companies to evaluate thousands of potential scenarios for their nearshoring strategy. These models incorporate probability distributions for key variables such as transport costs, delivery times, exchange rates, and political risk.

Scenario modeling must consider complex variable correlations. For example, a political crisis in a nearshore country can simultaneously affect labor costs, currency stability, and border transit times. Advanced models capture these interdependencies to provide more realistic risk assessments.

Real options theory offers a valuable conceptual framework for evaluating nearshoring decisions under uncertainty. Establishing nearshore operations can be seen as purchasing an option that provides future flexibility to respond to changing market conditions. Real options models quantify this flexibility’s value and help determine the optimal timing for investments.

Evaluating Cost vs. Time Trade-offs

Multi-objective optimization models allow companies to quantify the inherent trade-offs in nearshoring decisions. These tools can identify Pareto frontiers showing the optimal combinations of cost, delivery time, quality, and risk for various supply chain configurations.

Genetic algorithms and other heuristic optimization techniques can explore complex solution spaces to identify optimal network configurations. These models simultaneously consider supplier selection, distribution center locations, transport routes, and inventory levels to maximize total system value.

Incorporating Total Cost of Ownership (TCO) metrics into these models is essential. Nearshoring may involve higher production costs than traditional offshoring, but it can generate savings in inventory, transportation, and risk management that justify the difference. Advanced TCO models capture all these factors to provide comprehensive comparisons between strategies.

Real-World Cases of Nearshoring

General Electric exemplifies a successful nearshoring transition in its appliance division. The company relocated washer and refrigerator production from China to Mexico, establishing a plant in San Luis Potosí serving the North American market. This move, implemented between 2018 and 2020, reduced delivery times by 30% and generated significant logistics cost savings that offset Mexico’s higher labor costs.

Apple has gradually diversified its supply chain from China to other Asian countries like Vietnam, India, and Thailand, but has also explored nearshore options for the U.S. market. The company has increased component production in Mexico and established final assembly centers in Brazil for the Latin American market.

Ford Motor Company is a textbook case of nearshoring in the automotive industry. It consolidated its production operations in Mexico, with plants in Hermosillo and Cuautitlán serving both U.S. and Mexican markets. This strategy allowed Ford to benefit from NAFTA (now USMCA) while staying close to

Whirlpool Corporation moved refrigerator production from China to Mexico in 2019, establishing operations in Apodaca, Nuevo León.
The company reported that although labor costs increased by approximately 15%, savings in transportation, inventory, and time-to-market generated a positive ROI in the second year of operation.

In the textile sector, Gildan Activewear exemplifies a regional nearshoring approach.
The Canadian company established manufacturing operations in Honduras, Nicaragua, and El Salvador to serve the North American market, leveraging regional trade agreements and geographic proximity to effectively compete with Asian products.

These cases demonstrate that nearshoring success does not rely solely on geographic relocation, but on a comprehensive reconfiguration of the supply chain, including development of local suppliers, investment in technology, and adaptation of operational processes.

Considerations in LATAM: Infrastructure, Capacity, and Political Risk

Latin America presents significant opportunities as a nearshore destination for the U.S. market, but also unique challenges that companies must carefully evaluate. The region offers competitive advantages in labor costs, geographic proximity, and favorable trade frameworks, but faces limitations in infrastructure and political stability that require specific mitigation strategies.

Latin America’s logistics infrastructure has improved considerably over the last decade, but there are still significant disparities between countries and regions. Mexico has the most developed infrastructure, with modern logistics corridors connecting major industrial zones with the U.S. border. The Port of Manzanillo and the border crossings at Tijuana and Ciudad Juárez handle significant volumes with relative efficiency.

Colombia has invested heavily in port and transport infrastructure, positioning itself as a logistics hub for South America. The ports of Cartagena and Buenaventura have modernized their operations, and the country has developed specialized free trade zones offering fiscal and logistical advantages for nearshore operations.

Brazil, due to its size and internal market, represents a special case. Its internal infrastructure is complex due to vast distances, but ports such as Santos have reached international standards. The country offers advantages for companies looking to serve both the Brazilian market and export to other countries in the region.

Manufacturing capacity varies significantly across Latin American countries. Mexico has developed sophisticated industrial clusters, particularly in automotive and electronics, with multi-tier suppliers and advanced technical capabilities. Costa Rica has specialized in high-tech manufacturing, attracting investments from companies like Intel and Boston Scientific.

Political risk is a crucial consideration for nearshoring decisions in Latin America. Government changes can significantly alter trade, labor, and tax policies. Venezuela and Nicaragua exemplify how political instability can destroy nearshore investment value, while countries like Chile and Uruguay have maintained political stability and a predictable regulatory framework.

Currency fluctuations add another layer of complexity. Currencies like the Mexican peso, Brazilian real, and Colombian peso can experience significant volatility against the U.S. dollar, affecting the competitiveness of nearshore operations. Companies should implement currency hedging strategies or structure contracts in U.S. dollars to mitigate this risk.

The availability of qualified talent varies greatly between countries and sectors. Mexico has a solid base of engineers and technicians specialized in manufacturing, while Costa Rica and Uruguay have developed capabilities in technology services and business processes. Brain drain to the United States remains a persistent challenge for several countries in the region.

Is It Worth Adopting Nearshoring Now or Waiting?

The decision to implement nearshoring involves complex strategic considerations that go beyond a traditional cost-benefit analysis. Companies must evaluate their current competitive position, the urgency of their risk mitigation needs, and their capacity to execute a complex transition in an uncertain environment.

Companies operating in time-sensitive sectors, such as fast fashion or consumer electronics, may justify an accelerated transition to nearshoring. The ability to quickly respond to changes in demand or market trends can generate competitive advantages that outweigh the transition costs. These industries also face growing pressure from sustainability-conscious consumers who favor products with lower carbon footprints.

Timing is crucial. Early adopters of nearshoring can secure access to the best suppliers and locations before competition increases the demand for nearshore resources. However, being a pioneer also entails taking on market and supplier development risks that may not materialize as expected.

The company’s financial situation significantly influences the viability of nearshoring. The transition requires substantial investments in supplier development, system reconfiguration, and potentially new infrastructure. Companies with capital constraints may prefer gradual approaches or strategic partnerships that reduce upfront investment requirements.

Product complexity and quality requirements also affect timing decisions. Simple products with standardized manufacturing processes can be transitioned more quickly to nearshore suppliers. Products requiring specialized technical capabilities or extremely high quality standards may need longer supplier development and knowledge transfer periods.

Geopolitical considerations add urgency for some companies. Trade tensions between the U.S. and China, though subject to change with new administrations, represent a structural risk for companies highly dependent on Chinese suppliers. Companies in sectors considered strategic or sensitive to national security may face regulatory pressure to diversify their supply chains.

The general recommendation favors a gradual and strategic approach. Companies can start with pilot projects in less critical product categories, develop nearshore supplier management capabilities, and gradually scale their operations. This approach allows for organizational learning, risk mitigation, and iterative adjustments that improve long-term success prospects.

However, the cost of waiting must also be considered. Global supply chain disruptions persist, maritime transport costs remain volatile, and competition for nearshore resources is intensifying. Companies that indefinitely postpone nearshoring assessments may find themselves at a competitive disadvantage when circumstances force them to act under pressure.

The optimal decision requires company-specific analysis, considering the industry, competitive position, organizational capabilities, and strategic goals. Predictive models and scenario analysis can inform this decision, but successful implementation will depend on the company’s execution capacity and its willingness to manage the inherent complexity of supply chain transformation.

Hybrid Models in Supply Chain: Combining Simulation and Analytics

The increasing complexity of modern supply chains has led companies to seek more sophisticated solutions for strategic and operational decision-making. Hybrid models, which integrate simulation techniques with advanced analytical methods, are emerging as an innovative response to the challenges faced by supply chain professionals in the digital age.

The convergence of big data, enhanced computational capabilities, and more efficient algorithms has opened new possibilities for developing modeling tools that leverage the best of both worlds: the mathematical precision of analytical models and the representational flexibility of simulation. This evolution addresses the need for systems capable of handling both the structural complexity and inherent variability of contemporary logistics operations.

What Are Hybrid Models in Supply Chain?

Hybrid supply chain models represent an advanced methodology that systematically combines discrete event simulation techniques with mathematical optimization models and predictive analytics. This integration enables the resolution of complex supply chain problems that require both uncertainty management and the optimization of limited resources.

A typical hybrid model incorporates deterministic components to optimize strategic decisions, while using stochastic simulation to evaluate system behavior under varying scenarios. This methodological duality allows planners to obtain robust solutions that consider both optimization goals and operational risk factors.

The distinguishing feature of these models lies in their ability to switch between different modeling paradigms according to the specific needs of the problem. For example, they may use linear programming to determine optimal production capacities, while employing Monte Carlo simulation to assess the impact of disruptions in the distribution network.

These systems integrate multiple real-time data sources, including transactional data from ERP systems, operational data from IoT sensors, and external variables such as weather conditions or market fluctuations. This connectivity allows for continuous model parameter updates and adaptive recommendations.

Why Combine Simulation and Analytical Models?

The evolution toward hybrid models addresses the inherent limitations of purely analytical or purely simulation-based approaches. This synergistic combination overcomes the individual weaknesses of each methodology while enhancing their respective strengths.

Traditional analytical models, though capable of producing mathematically verifiable optimal solutions, often require simplifications that may not accurately reflect real operational complexity. On the other hand, simulation models offer detailed representations of system behavior but may lack explicit optimization mechanisms and require extensive analysis to identify optimal configurations.

The integration creates more robust decision support systems capable of managing both resource optimization and operational risk quantification. This duality is especially valuable in environments where strategic decisions must be considered alongside tactical and operational variability.

Deterministic vs. Stochastic Approaches

Deterministic approaches are characterized by using fixed values for all model parameters, assuming full certainty about future conditions. These methods provide precise and reproducible solutions, ideal for strategic planning problems where optimal configurations are sought under known or highly confident conditions.

In contrast, stochastic approaches explicitly incorporate uncertainty through probability distributions for key parameters. This allows modeling of inherent variability in demand, processing times, resource availability, and other critical factors affecting supply chain performance.

The fundamental difference lies in how each approach handles uncertainty: while deterministic models seek the optimal solution for a specific scenario, stochastic models aim for robust solutions that maintain strong performance across multiple possible scenarios.

Hybrid models leverage this complementarity by using deterministic optimization to establish the basic decision structure and stochastic simulation to assess robustness and identify potential vulnerabilities under various operational conditions.

Strengths and Limitations of Each Method

Analytical models excel in their ability to guarantee mathematical optimality within defined constraints, providing computationally efficient solutions that can scale to large problems. Their deterministic nature facilitates result interpretation and trade-off analysis between conflicting objectives.

However, these advantages come with significant limitations, including the need to simplify complex real-world representations, difficulty in incorporating nonlinear behaviors, and a tendency to underestimate risks associated with operational variability.

Simulation models stand out for their ability to faithfully represent complex systems with multiple interactions, incorporate realistic statistical distributions, and evaluate emergent system behaviors. They can model detailed temporal dynamics and feedback effects that are difficult to capture analytically.

Simulation’s limitations include the lack of explicit optimization mechanisms, the need for extensive exploration of the solution space to identify superior configurations, and significant computational requirements to obtain statistically reliable estimates.

Architecture of a Hybrid Model Applied to Logistics

The architecture of a hybrid model for logistics applications requires a modular structure that enables seamless integration between analytical and simulation components while maintaining the flexibility needed to adapt to different operational contexts and decision-making requirements.

A typical architectural design includes distinct layers for data management, analytical processing, simulation, optimization, and results presentation. This separation facilitates maintenance, scalability, and reuse of components across different applications.

The data layer centralizes information management from multiple sources, implementing validation, cleaning, and transformation mechanisms to ensure the quality and consistency required by downstream models. This layer also handles historical storage and synchronization with operational systems.

Integration Between Discrete Event Simulation and Optimization Models

Effective integration between discrete event simulation and optimization models requires sophisticated mechanisms for information exchange and temporal coordination between the two paradigms. This integration can be implemented through various architectural patterns, each with specific advantages depending on the application context.

The most common pattern uses optimization to generate initial policies or configurations that are then evaluated and refined through simulation. This approach leverages the computational efficiency of optimization to explore the solution space while using simulation to validate performance under realistic conditions.

A more advanced variant embeds optimization within the simulation loop, where specific decisions are dynamically optimized based on the current state of the simulated system. This approach is particularly valuable for problems requiring continuous adaptation to changing conditions.

Temporal coordination between components requires synchronization mechanisms to ensure consistency between the different time horizons handled by optimization (typically strategic or tactical) and simulation (usually operational). This includes protocols for parameter updates, system state transfer, and result aggregation.

Connectivity with Real Data (ERP, MES, IoT Sensors)

Connectivity with real operational systems is a critical aspect that differentiates academic hybrid models from practical industrial implementations. This connectivity must handle the heterogeneity of data sources, communication protocols, and update frequencies typical of the modern industrial environment.

Integration with ERP systems provides access to core master data, including product structures, resource capacities, standard costs, and supplier information. This connection also enables bidirectional synchronization where the hybrid model can directly influence ERP operational planning.

MES (Manufacturing Execution Systems) provide real-time visibility into manufacturing operations, including production order progress, equipment utilization, product quality, and maintenance events. This information allows continuous model parameter updates and validation of predictions against real performance.

Incorporating data from IoT sensors introduces continuous monitoring capabilities that significantly enhance model accuracy. This data includes environmental conditions, equipment vibrations, real-time inventory levels, and quality metrics that support predictive maintenance and adaptive optimization.

Use Cases in Distribution, Production, and Warehousing

Hybrid models are especially valuable in areas where operational complexity combines with the need for optimization under uncertainty. These applications range from strategic network design decisions to tactical optimization of daily operations.

In distribution, hybrid models enable simultaneous optimization of the logistics network structure and operational routing and scheduling policies. This capability is particularly valuable for companies operating multi-tier distribution networks with multiple transportation modes and variable delivery windows.

In production, applications focus on coordinating capacity planning, production scheduling, and inventory management under uncertain demand. Hybrid models can optimize product mix decisions while simulating the impact of variability in processing times and material availability.

Planning with Dynamic Constraints

Planning with dynamic constraints represents one of the most challenging and valuable use cases for hybrid models, where system constraints continuously change in response to operational conditions, external events, or evolving business policies.

Such problems frequently arise in flexible manufacturing environments where available capacity varies based on equipment configurations, specialized personnel availability, and scheduled or corrective maintenance requirements. Hybrid models can optimize resource allocation while simulating the impact of different availability scenarios.

In logistics, dynamic constraints include changes in transportation capacity due to temporary regulations, weather conditions, or urban congestion. Hybrid models allow re-optimization of routes and schedules while evaluating solution robustness against anticipated disruptions.

Effective implementation requires adaptive algorithms that can efficiently update existing solutions when constraints change, avoiding the need to re-solve the entire optimization problem. This includes incremental optimization techniques and solution repair heuristics.

Contingency Simulation and Multi-Stage Decision Making

Contingency simulation using hybrid models allows systematic evaluation of disruptive events and the development of robust contingency plans that can be quickly implemented when real disruptions occur.

This approach is particularly valuable for low-probability but high-impact events such as natural disasters, labor strikes, or massive equipment failures. Hybrid models can pre-compute optimal responses for different contingency scenarios, significantly reducing response time during real crises.

Multi-stage decision-making adds further complexity by considering how current decisions affect future options under uncertainty. Hybrid models can use stochastic dynamic programming to optimize decision sequences while employing simulation to evaluate the performance of specific policies.

Integrating decision trees with Monte Carlo simulation enables the evaluation of adaptive strategies that modify the course of action based on the gradual resolution of uncertainties. This approach is especially useful for capacity investment or supplier selection decisions under uncertain demand.

Advantages Over Traditional Tools

Hybrid models offer significant competitive advantages compared to traditional planning and optimization tools, particularly in terms of predictive accuracy, solution robustness, and adaptability to changing conditions.

The most notable advantage lies in the ability to deliver solutions that are simultaneously mathematically optimal and robust to operational variability. This duality eliminates the need to choose between theoretical precision and practical applicability—a common dilemma with traditional tools.

Hybrid models also overcome the scalability limitations typical of purely analytical or simulation-based approaches.

Reshoring Scenario Evaluation: How to Simulate Impacts on Tariffs and Operations

Reshoring Scenario Evaluation: How to Simulate Impacts on Tariffs and Operations
Do you want to technically compare reshoring scenarios? We’ll show you how to use flexible models to analyze costs, tariffs, and lead times in the supply chain.

What is reshoring and why is it back at the center of logistics strategy?
Reshoring is the process of bringing back production activities that were previously offshored to the country of origin or nearby regions. This strategy has gained prominence in recent years due to geopolitical factors, disruptions in global supply chains, rising costs in Asia, and the need for greater resilience and control over production.
For decades, many companies moved operations to countries with lower labor costs. However, events like the pandemic, rising tariffs, logistics delays, and volatility in global markets have led many to reconsider those decisions. Today, reshoring is emerging as a viable alternative to improve time-to-market, reduce external dependency, and strengthen the connection with end customers.

Key variables affected by reshoring
The decision to relocate production operations involves evaluating multiple strategic, financial, and operational variables. Each of them directly impacts business results and should be carefully simulated before implementing changes.

Labor costs, tariffs, and duties
One of the main drivers of offshoring was the reduction in labor costs. In a reshoring process, this component tends to increase but can be offset by reduced tariffs, import duties, and international logistics costs.
In addition, changes in trade agreements, protectionist policies, or government incentives can significantly alter the economic balance of the process. Modeling these impacts across different scenarios is crucial for making well-founded decisions.

Lead times and operational flexibility
Relocating production closer to the final market can reduce lead times from weeks to days, enabling faster responses to demand changes. Operational flexibility improves, allowing for shorter production cycles and less inventory.
This agility can become a decisive competitive advantage in industries where customization, seasonality, or speed are critical.

Local infrastructure and production capacity
Not all countries have the same industrial or technological infrastructure. The local ability to absorb production processes, access quality suppliers, and attract technical talent are key factors.
Reshoring scenario evaluation must consider these structural limitations or advantages, which influence both costs and the scalability of the operating model.

How to evaluate reshoring scenarios using flexible models
The complexity of these decisions requires tools that allow comparison of multiple possible configurations, considering dynamic variables and real business constraints.

Discrete event simulation
Discrete event simulation allows for detailed representation of a logistical or industrial operation, including times, resources, queues, material flows, and state changes.
This technique is particularly useful for assessing how reshoring would impact a plant, warehouse, or distribution network, measuring effects on time, costs, productivity, and bottlenecks. Different layouts, shifts, technologies, or demand scenarios can be tested.

Optimization models under multiple constraints
In addition to simulating operations, optimization models help find the most efficient configuration among many possible scenarios, considering capacity, cost, demand, and regulatory constraints.
Applied to reshoring, these models help determine which volumes to relocate, which plants to use, how to supply each region, and which logistics routes to optimize. They can be combined with advanced heuristics for large-scale problems.

Risk and sensitivity evaluation
A proper reshoring scenario evaluation goes beyond average results to include variability and risk associated with different decisions. Sensitivity analysis, Monte Carlo simulations, or pessimistic/optimistic scenarios help understand system behavior under unexpected changes.
This perspective is key to avoiding investments that are only profitable under ideal conditions and to designing resilient supply chains.

Comparison with offshoring and nearshoring scenarios
To justify a reshoring process, it is essential to compare all possible scenarios: continuing offshoring, moving operations to nearby countries (nearshoring), or fully relocating back home.

Decision matrices based on quantifiable outputs
Using decision matrices that compare quantifiable variables such as logistics costs, initial investment, delivery times, expected quality, political risk, and scalability helps make strategic decisions on solid grounds.
These visual tools incorporate multiple dimensions into the analysis and present results clearly for executive decision-making.

Practical cases in industrial companies
Several industrial companies across Latin America, Europe, and the U.S. have started using simulation and optimization tools to evaluate reshoring projects. Some typical cases include:

  • Automotive industry: Simulation of supply chains with distributed production in Mexico, the U.S., and China to assess total costs and delivery times.
  • Pharmaceutical companies: Risk analysis to relocate critical processes and reduce dependency on active ingredients from Asia.
  • Appliance manufacturers: Optimization of local assembly lines versus direct imports from Asia.

These cases show there is no one-size-fits-all answer: the key lies in having adaptable models tailored to each company’s specific conditions.

When is reshoring truly profitable?
Reshoring becomes profitable when the benefits in time, control, quality, and flexibility outweigh increased labor or operational costs. It is also worthwhile when it helps reduce systemic risks, meet local regulations, or better serve the end customer.
However, each case must be analyzed individually. Simulation and optimization tools allow for a technical, quantified analysis aligned with each organization’s strategic goals.
