P300 FCS

Whereas in Preactor 200 FCS the ‘secondary resources’ are modeled as having infinite capacity, in Preactor 300 FCS these can be either modeled as infinite or finite so this is a multiple constraint finite scheduling system. The capacity of ovens, furnaces and tanks can also be modeled using secondary resources to restrict the number batch sizes within them. Attributes of orders or products can be used to restrict which orders can go together into a resource.

Secondary resources can also be placed in groups and selections made within the group when scheduling. This can be useful for modeling labor that has different skill sets.

More complex resource selection and routing constraints can be defined. Preferred resources within a resource group (work-center) can be defined. The resource group to be used on an operation step can be changed according the resource selected on the previous step.

Operations can be restricted on when they are placed on subsequent resources depending on the timing of previous operations to limit the delay or force a gap between them. The total duration of an operation (including suspensions due to off-shift time) can also be limited automatically. Mid batch times (quantity completed at a specific time) may be entered and end times automatically re-calculated.

A Hot Spots Grid is available for tabular display of capacity usage. The Schedule Analysis tool can compare alternate schedules based on due date compliance, make span and other criteria. Additional reports are available such as order and schedule cost. Order cost calculation uses the usage of resources, shift pattern multipliers and materials.
