Supply Chain Simulation Improves Order Processing Efficiency


The Challenge

Understanding the complex procedures in order to effectively plan batching is an intensive and time consuming task.

The Arena Solution

The CEDC developed a supply chain simulation model to enable them to better plan and batch orders for shipment.

This Arena simulation model obtained real-time order information from the existing Microsoft Access Database. The database included important data like country, due date, shipment date and quantity.

A special user interface was developed to specify additional parameters, like working hours, resource availability and Quality Control inspections. Through the user interface, it was also possible to test various strategies, such as time-based or quantity-based batching.

With this supply chain simulation model, it was possible to evaluate a variety of scenarios based upon the current order and shipping requirements from the facility.


The supply chain simulation model was able to easily cover 90-95% of the orders from the facility. While running the simulation model did take a few minutes, the resulting efficiency and order accuracy more than made up for the extra time. By utilizing this model, planners were able to rapidly make new batches of orders upon release of previous orders, perform what-if analyses to identify more efficient batching alternatives, evaluate the benefits/ impact to utilize multiple carriers.

In addition to these benefits, Rockwell Automation was also able to reduce the required training time for new planners from six months to just one week.
