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.

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
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.

Picking is one of the most crucial activities within logistics and warehouse management. A good execution of this process can make a difference in the operational efficiency, customer satisfaction and profitability of a company. Below, we will explore the importance of optimizing picking, the benefits it brings and the main strategies to achieve it.

What is picking and why is it important to optimize it?

Picking refers to the process of selecting and collecting products in the warehouse to fulfill customer orders. It represents one of the most critical steps in the logistics chain, as any error or delay can lead to delivery delays and, consequently, affect customer satisfaction.
Optimizing this process involves implementing work methods, technologies and good practices that reduce times, minimize errors and make the most of available space and resources. By doing so, companies can significantly improve their competitiveness and profit margins.

Efficient inventory management is one of the fundamental pillars for business success in today’s competitive market. However, one of the most significant challenges faced by organizations is stockouts, a phenomenon that can have deep repercussions on multiple aspects of the business. This article provides a comprehensive analysis of the associated costs, their underlying causes, and the most effective strategies for their prevention and management.

What Are Stockout Costs?

Stockout costs, also referred to as stockout or out-of-stock costs, represent the total financial impact a company experiences when it is unable to meet customer demand due to a lack of available inventory. These costs go beyond simple lost sales, encompassing a broader range of financial and operational consequences.

In today’s business context, these costs can manifest in various ways, including direct sales losses, opportunity costs, additional management expenses, and, significantly, the long-term impact on customer loyalty and brand reputation. A deep understanding of these costs is essential for developing effective inventory management strategies.

Common Causes of Stockouts

Lack of Supply Chain Planning

Inadequate supply chain planning can manifest through several interrelated factors:

• Poor communication between departments leads to operational discoordination, resulting in late or incorrect orders.
• Disintegrated information systems hinder real-time visibility of available and in-transit inventory.
• The absence of standardized inventory management processes creates inconsistencies in stock handling.

Additionally, the lack of clear protocols for emergency situations and the absence of contingency plans can significantly worsen the impact of any supply chain disruptions.

Unexpected or Underestimated Demand

Unexpected demand fluctuations can arise due to various factors:

• Changes in market trends can lead to unforeseen demand spikes.
• Miscalculated seasonal events can quickly deplete available inventory.
• Promotions and marketing campaigns can create demand that exceeds initial forecasts.
• Shifts in consumer behavior, especially in the digital age, can be faster and more dramatic than ever.

Impact of Stockout Costs

Loss of Sales and Customers

The immediate impact of a stockout is reflected in lost sales, but the long-term consequences are even more significant:

• Market research indicates that approximately 70% of consumers will choose to buy from a competitor when faced with a stockout. Even more concerning, about 30% of these customers will not return to the original store. Customer Lifetime Value (CLV) is severely impacted, affecting the future profitability of the business.

Increased Operational Costs

Stockouts trigger a series of additional operational costs:

• Emergency orders often come with significant surcharges.
• Expedited shipping can cost up to three times more than regular transportation.
• Overtime costs for employees to manage these situations increase labor costs.
• Additional administrative resources needed to handle crisis situations raise overhead expenses.

Damage to Company Reputation

In the digital age, the reputational impact can be particularly severe:

• Social media amplifies negative customer experiences quickly.
• Negative online reviews have a lasting effect on brand perception.
• Loss of trust can affect not only out-of-stock products but the entire range of products offered by the company.

How to Calculate Stockout Costs?

The precise calculation of stockout costs requires a detailed analysis of multiple components:

• Lost Sales = (Unmet Demand × Unit Price) + (Lost Profit Margin)
• Additional Operational Costs = Emergency Order Costs + Special Transportation Costs + Overtime
• Customer Impact = (Number of Lost Customers × Average Customer Lifetime Value)
• Administrative Costs = Additional Staff Hours × Hourly Rate
• Total Costs = Sum of all previous components + Estimated Intangible Costs

Strategies to Prevent Stockouts

Implementing Inventory Software

Modern technology offers sophisticated solutions for inventory management:

• Real-time inventory management systems provide instant visibility of stock levels.
• Automated reordering reduces the risk of human error.
• Early warning systems identify potential problems before they become crises.
• Integration with other business systems improves overall coordination.

Accurate Demand Forecasting

Demand forecasting accuracy requires a multifaceted approach:

• Historical data analysis must be combined with identifying current trends.
• Seasonal factors should be considered along with special events and planned promotions.
• The implementation of machine learning techniques can significantly improve prediction accuracy.

Efficient Supplier Management

A strong relationship with suppliers is essential:

• Service level agreements (SLAs) should clearly define expectations and penalties.
• Supplier diversification reduces the risk of dependency on a single source.
• Regular and transparent communication facilitates proactive problem resolution.

Technological Tools to Minimize Stockout Risk

Modern technology offers multiple solutions for effective inventory management:

• Integrated ERP systems provide a holistic view of business operations.
• Warehouse Management Systems (WMS) optimize warehouse operations.
• Predictive analytics solutions identify patterns and trends.
• RFID systems enable real-time tracking of inventory.
• AI platforms automatically optimize inventory levels.

Optimization and Control to Reduce Stockout Costs

To significantly reduce the costs associated with stockouts, companies must focus on the continuous optimization of their processes and the application of rigorous controls. Some final recommendations include:

• Monitor Inventory in Real Time: Use dashboards and automated reports that display inventory status.
• Maintain a Culture of Continuous Improvement: Conduct internal audits and periodic evaluations to identify bottlenecks or inefficient processes.
• Train the Workforce: Provide training for all areas involved in the supply chain, promoting collaboration and information exchange.
• Define Contingency Plans: For scenarios of unusual demand, transportation delays, weather issues, or other potential disruptions that may affect supply.

Stockouts not only jeopardize immediate revenue but also damage customer trust and erode the company’s image. However, with solid planning, more accurate demand forecasting, the adoption of specialized technology, and continuous process optimization, it is possible to maintain proper stock levels and provide quality service that translates into customer loyalty and long-term sustainable growth.

Effective management of stockout costs requires a continuous commitment to operational excellence. Companies that implement comprehensive strategies not only minimize financial losses but also strengthen their competitive position and improve customer satisfaction. Investing in technology, processes, and trained personnel translates into higher operational efficiency and better long-term profitability.

Supply chain management is essential for companies to remain competitive in today’s market. With digitalization transforming every aspect of business, it’s crucial to understand the differences and implications of transitioning from a traditional to a digital supply chain. In this article, we’ll explain what these supply chains are, their main differences, benefits, and the pros and cons of digital transformation.

What is a Traditional Supply Chain?

Traditional supply chains are linear structures that rely on manual and sequential processes to move goods from supplier to end consumer. These chains are typically composed of multiple links such as suppliers, manufacturers, distributors, and retailers, which operate relatively independently with limited communication.

Decision-making is based on historical data, and the ability to quickly adapt to changes is limited. Traditional chains rely on predefined delivery cycles, such as weekly or monthly deliveries, and operate with large, standardized packages to optimize transportation costs.
