Overview of Oracle Capacity Planning

Categories: ERP,Other

From the User Guide

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:
• rough cut capacity planning (RCCP) to validate your master
• detailed capacity requirements planning (CRP) to validate your
MRP plans
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
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.
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
• Underload
• Balance
Overload exists when your required capacity is greater than your
available capacity.
Underload exists when your required capacity is less than your
available capacity.


Balance exists when your required capacity equals your available
