Question 70 - CPIM-Part-2 discussion

Rough-cut capacity planning (RCCP) is a long-term capacity planning technique that validates the master production schedule (MPS) by comparing the required capacity and the available capacity of critical resources. Critical resources are those that have the most impact on the production process, such as machines, labor, or materials. RCCP helps to identify any potential imbalances or bottlenecks in the production system and to adjust the MPS or the resource availability accordingly.

To perform RCCP, one of the forms of data that is required is critical work center availability. A work center is a location where one or more resources perform a specific operation or a group of operations. A critical work center is a work center that has a high utilization rate, a low flexibility, or a high influence on the production output. Critical work center availability is the amount of time or capacity that a critical work center can offer for production activities. Critical work center availability can be affected by factors such as shifts, holidays, maintenance, breakdowns, or setups. RCCP uses critical work center availability to determine whether there is enough capacity to meet the planned production.

Current work in process (WIP) is not a form of data that is required for RCCP. WIP is the inventory of partially finished goods that are waiting for further processing or assembly. WIP is not relevant for RCCP, as RCCP focuses on the future demand and capacity, not the current inventory status.

Resource requirements plan is not a form of data that is required for RCCP. Resource requirements plan is the output of RCCP, not the input. Resource requirements plan is a report that shows the projected load and capacity of each critical resource over a planning horizon. Resource requirements plan can help to identify any gaps or surpluses in capacity and to take corrective actions.

Work center queues are not a form of data that is required for RCCP. Work center queues are the waiting lines of jobs or orders at a work center. Work center queues are an indicator of short-term capacity issues, such as delays, backlogs, or congestion. Work center queues are not relevant for RCCP, as RCCP focuses on the long-term capacity planning, not the short-term scheduling.
