P400 APS

The Preactor 400 APS has additional functionality to deal with more complex scheduling problems and in addition focuses on the restrictions imposed by materials. Many ERP systems will create orders for each level of the Bill of Materials (BoM). These could be manufacturing orders or materials that are purchased. These orders are connected or pegged together and the materials produced netted off. These links are used as part of the scheduling process so that dependent orders are not scheduled until all the materials required are completed by the producing orders.

Plots are available for each material and it is also possible to define the timing of shortages that will hold up the production process.

Preactor 400 APS also offers additional optimization rules that can be further customized for each application. These rules can be event based (simulation forward only) or order based. Standard dispatching rules include those to Minimize Setup time, Minimize Late Orders, use a Preferred Sequence at each resource, Bottleneck Scheduling (Theory of Constraints) and Campaigning.

Rules can be made to be customer, product or resource specific and virtually any logic can be built into a customized scheduling rule. These can be built using the PESP tool, a scripting language with standard building blocks, or by using a programming language such as .NET and Visual Basic.

Additional reports available such as material shortages report.
