The Capacity Requirements Planning (CRP) module uses MRP planned orders, other work orders, and repetitive schedules to determine work center load and generate a capacity requirements plan for a department, work center, or machine.

This following topics explain how to generate and maintain a capacity requirements plan.

Introduction to CRP
Explains the functions of CRP and how they are performed.

Defining Capacities
Defines capacities by department and work center.

Executing CRP
Outlines when and why to run CRP.

Generating Load Reports
Explains how to generate reports for department, work center, or machine, as well as how to review input and output.

Adjusting Capacity and Load
Explains how to adjust timing and amount of load.

CRP calculates workload for a department, work center, or machine. It does this by exploding the routings and processes for MRP planned and firm planned orders and determining start and due dates for each operation, using the work center and shop calendars and a technique called back scheduling.

The resources used to process orders on the shop floor are work centers, departments, and machines. The capacity of a department or work center is the time available for production in that location.

The capacity of a department is the total number of available labor hours per day for all work centers in that department, defined in Department Maintenance (14.1).

See Departments for details.

The capacity for a work center is the number of machines or personnel available for that work center, defined in Work Center Maintenance (14.5), multiplied by work hours, defined in the shop floor calendar. You can define and maintain shop floor calendars using Calendar Maintenance (36.2.5).

See User Guide: QAD System Administration for more information about shop calendars.
