Operations & Supply Chain Exam Math: EOQ, MRP, Capacity & Forecast Error (CPIM/CSCP-Style Practice)
Practice the calculation questions of operations and supply chain exams: MAD, MAPE, bias and tracking signal, EOQ with price breaks, safety stock from MAD, MRP netting and lead-time offset, MPS and ATP, CRP load vs rated capacity, inventory turns and ABC cycle counting, every cell checked as you go. Independent practice, not affiliated with ASCM; CPIM and CSCP are registered marks of ASCM (APICS).

About this course
Operations and supply chain exam math practice for CPIM-style and CSCP-style calculation questions, worked on one fictional pump maker in graded spreadsheet labs, for exam candidates, planners, buyers and operations students. You measure MAD, MAPE, bias and the tracking signal of an eight-month forecast, compare the total annual cost of the EOQ with a quantity discount, turn a MAD into safety stock and a reorder point for a 95% service level, explode planned orders through MRP with netting, lot-for-lot and lead-time offset, project the master production schedule and calculate discrete available-to-promise, load a work centre against rated capacity with capacity requirements planning, calculate inventory turns, days and weeks of supply and classify ten parts ABC to plan cycle counts. Independent practice, not affiliated with ASCM. CPIM and CSCP are registered marks of ASCM (APICS). The first lab is free.
