Overview of Capacity Planning

Oracle Capacity lets you calculate your capacity load ratio by resource or production line. It ensures that you have sufficient capacity to meet your production requirements.

Oracle Capacity provides you with two levels of capacity planning:

Routing–Based and Rate–Based Capacity Planning

You can plan capacity for individual resources assigned to operations on routings, or you can plan capacity by production line. Required and available capacity for routing–based plans are stated in hours per week per resource, and for rate–based plans by production rate per week per line. Resource requirements are also based on the effective date ranges in routings.

Resource requirements for phantom assemblies are included in the requirements for the planned orders of their parent assemblies.

Rough Cut Capacity Planning (RCCP)

You can use rough cut requirements planning to verify that you have sufficient capac­ity available to meet the capacity requirements for your master schedules. In this way, you can monitor long–term plan trends in required and available capacity. RCCP is typically restricted to key or critical resources. You should only generate an MRP plan using a master schedule that you have proved to be realistic and attainable.

Capacity Requirements Planning (CRP)

You can use CRP to verify that you have sufficient capacity available to meet the capacity requirements for your MRP plans. In this way, you can identify short term discrepancies between required and available capacity.

CRP typically verifies capacity for all the resources required to meet your material plan.

Bills of Resources

You can automatically generate or manually enter bills of resources. You can manually change any automatically generated bill of resource to simulate changes in available capacity. You can choose to roll up manual changes when loading a bill of resources. You can also simulate different manufacturing methods, as well as long–term plan resource requirements, by manually defining multiple bills of resources for the same item.

Resource Groups

You can define resource groups, assign key or critical resources to the group, and then generate bills of resources for individual resource groups. You can then use the bill of resources to generate RCCP plans that are limited to those resources assigned to your resource group. You can also specify a resource group when using many of the Oracle Capacity inquiries and reports.

Simulation

You can modify the availability of individual resources, group together your modifications in a simulation set, and generate RCCP and CRP plans for individual simulation sets.

Multi–Department Resources

You can define resources that are shared across multiple departments, and generate RCCP and CRP plans that show individual (by department) or aggregate capacity load ratio for the shared resource.

Capacity Load Ratio

The output of both RCCP and CRP is a statement of your capacity load ratio—by resource or by production line. Oracle Capacity calculates capacity load ratio using the following formula:

capacity load ratio = required capacity / available capacity

Analysis of your capacity load ratio can reveal one of three situations:

Overload

Overload exists when your required capacity is greater than your available capacity.

Underload

Underload exists when your required capacity is less than your available capacity.

Balance

Balance exists when your required capacity equals your available capacity.
