What is simulation?
Simulation is a representation of a real-life system that mimics its behaviour over time. It is a dynamic process in which a specific starting situation is used to show how a system would develop over time. This makes it possible to study how a system behaves under different circumstances.
Because a simulation runs faster than the actual operation, bottlenecks can be identified quickly, and different scenarios can be tested. In logistics, for example, a warehouse or a logistics process can be modeled in a simulation model. Within the model, different situations can be tested, such as an increase in order volume, changes in staffing levels, or the implementation of automation solutions. This can all be done without disrupting the daily operation. Below are five concrete benefits we have seen.
5 benefits of simulation
1. Identifying bottlenecks
Simulation provides a clear overview of where queues or bottlenecks occur in the process, such as during inbound, picking, or packing. During a simulation, it becomes visible how goods flow through the system and where delays occur. These bottlenecks are often the result of limited capacity, insufficient staffing, or a lack of storage space. In addition, key performance indicators such as resource utilization, waiting times, and throughput times can be calculated. These insights make it possible to implement effective process improvements.
2. Capacity and workforce optimization
By using simulation, organizations can perform different capacity calculations. By simulating different order volumes, organizations can gain insight into the maximum capacity of the process and the required staffing levels. For example, it can determine how many pickers and packers are required for a certain order volume. It helps prevent both understaffing and overstaffing.
3. Testing changes without risk
Simulation makes it possible to test different scenarios and evaluate the impact of process changes. Changes are first tested in a virtual environment before being implemented in practice. For example, it can be used to determine whether it is more efficient to add extra staff or introduce an additional machine into the process. This reduces risks and supports better-informed decisions.
4. Reducing costs
The use of simulation can lead to cost savings in terms of investments, operational activities and staffing. By testing investments in a simulation environment first, it becomes clear whether they will deliver the expected results. In addition, simulation can show where operational processes can be optimized and how staff can be deployed more efficiently. This helps organizations make better-informed decisions and avoid unnecessary costs.
5. Better decision-making
Simulation supports decision-making by using data instead of assumptions. Multiple scenarios can be compared to understand the impact of various choices and identify the most effective solution. This provides valuable insights, reduces uncertainty, and helps organizations make better-informed decisions.
How can 4Supplychain help?
In my opinion, simulation is valuable for better decision-making, but it is not always the right choice. If you are dealing with a simple calculation or only a few variables, an Excel analysis is often sufficient. Simulation becomes truly valuable when multiple factors influence each other, processes become more complex, or you want to understand the impact of major changes before implementing them.
At 4Supplychain, we help organizations determine which approach best fits their challenge. Using simulation software of InControl or SIMUL8, we build a simulation model based on your process and operational data. This model allows different scenarios, such as changes in order volumes, staffing levels, warehouse layouts, or automation, to be tested without disrupting daily operations. Based on the simulation results, we provide practical recommendations to help you optimize your processes, improve performance, and make confident, data-driven decisions.
