By firming planned orders, the planner can moderate fluctuations in the MRP system that might otherwise occur if the planning software kept making changes.

The impact of constant MRP changes on material planning can be disruptive, and this is called system nervousness.

During CRP, a load profile is produced by simulating load at workcenters. If there are imbalances, the planner must take action to resolve it.

The planner can employ load balancing techniques. The outputs of the CRP process are a schedule and a plan.

What creates a work center overload?

The total hours of work to be performed exceeds the work center's capacity.

How is tracking signal calculated?

The tracking signal is calculated when the sum of the forecast deviations is divided by the mean absolute deviation.

When using MDS (because material is expensive) for scheduling stages, a time-phased record of material balanced is used, and lots are added if it falls below minimum levels.

Then a load profile is compiled. Reconcile if capacity not in balance. Revise schedule if it cannot be reconciled.

Freebie. The capacity planning using overall factors (CPOF) technique for RCCP uses historical work center performance data to determine capacity.

This approach eliminates the need for engineered time standards, which are typically required in a bill of labor. Resource profile uses standard hours of load by time period to account for lead-time offsets.
