生产系统和供应链很难在理解影响物料流行为的因素所需的细节水平上进行建模。当使用集中式计划系统（如MRP或DRP）时，尤其如此。因此，一个测试台，包括一个规划模块和一个模拟器模块，已经开发。该试验台设计简单、透明、灵活。它支持研究和培训。规划模块使用基于电子表格的界面和嵌入在扩展的XML宏中的逻辑。模拟器模块由通用竞技场程序组成，当场景改变时，该程序不需要直接建模输入。模块之间的动态通信是通过使用XML来实现的。在不同的条件下可以观察到瞬态和稳态行为。可以比较使用MRP/DRP、再订货点或看板系统的生产系统或供应链。
Production systems and supply chains are difficult to model at the level of detail required to understand factors affecting the behavior of material flow. This is particularly true when use of centralized planning systems, such as MRP or DRP, is of interest. Therefore a test bed, comprised of a planning module and a simulator module, has been developed. This test bed is designed to be simple, transparent and flexible. It supports research as well as training. The planning module uses a spreadsheet-based interface and logic embedded in extensive VBA macros. The simulator module is made up of a generic ARENA program that requires no direct modeling inputs when scenarios are changed. Dynamic communication between the modules is facilitated using VBA. Transient and steady state behavior can be observed under diverse conditions. Production systems or supply chains using MRP/DRP, reorder points, or Kanban systems can be compared.
