What distinguishes a 'net change' MRP run from a 'regenerative' MRP run?
Answer: Net change recalculates only the items affected by recent transactions, while regenerative re-plans the entire database
Net change MRP updates only items impacted by changes since the last run, making it faster and more responsive than a full regenerative run.
In capacity requirements planning, 'load' on a work center is calculated as:
Answer: Sum of setup time plus run time for all planned and released orders scheduled at that work center
Load is the total setup and run time demand placed on a work center by all planned and released orders, compared to available capacity to identify overloads.
Which statement best describes the role of 'offsetting' in MRP calculations?
Answer: It moves planned order releases earlier in time by the item's lead time
Lead-time offsetting shifts the planned order release date earlier by the item's lead time so materials arrive when the gross requirement is due.
A plant manager wants to reduce manufacturing lead time without adding capacity. Which strategy is most directly effective?
Answer: Reduce queue time by controlling work-in-process levels and releasing fewer orders to the floor
Queue time typically constitutes 80–90% of manufacturing lead time; controlling WIP through input/output management directly reduces queue and shortens lead time.
In production planning, a 'chase demand' strategy means:
Answer: Varying production output to match demand fluctuations, adjusting workforce or overtime as needed
A chase strategy adjusts production rate and workforce up or down to follow actual demand, minimizing inventory at the cost of workforce flexibility.
When MRP creates a 'reschedule-in' exception message, it is recommending that the planner:
Answer: Move an existing order to an earlier date because requirements have accelerated
A reschedule-in message tells the planner that an open order's due date should be moved earlier to satisfy a requirement that is needed sooner than originally planned.
Which MRP planning concept uses the idea that items at the same low-level code are netted together before planned orders are exploded to child components?
Answer: Low-level coding and netting
Low-level coding ensures all demands for a shared part across all BOM branches are consolidated and netted at its lowest BOM level before child requirements are generated.
