Inventory Control • Inventory: • raw material • work in process • finish goods • Problems • Cost = Cp + Co + Cs + Ch + Csh • Lead time • Order Size • Reorder Point • Safety Stock • Etc jpsugiono@gmail.com (C)2007
Q Order point Q=d.t Average Inventory=Q/2 t t=Q/D Economic Order Quantity (Eoq) • Goal: minimized total inventory cost jpsugiono@gmail.com (C)2007
Purchasing Cost neglected, depend on ordering frequency Ordering Cost = (D/Q)Co • Holding Cost = (Q/2)Ch • Total Cost (TC) = (D/Q)Co + (Q/2)Ch • Reorder point (R) = L . DL • L=lead time • DL= demand at lead time jpsugiono@gmail.com (C)2007
Material Requirement Planning (MRP) • Goal : Determine Requirement and Schedule • Complexity Factor: • Product Structure (level of Bill of Material – BOM) • Lot Size • FPR (Fixed Period Requirement) • FOQ (Fixed Order Quantity) • EOQ (Economic Order Quantity) • L4L (Lot for Lot) • Lead Time Change jpsugiono@gmail.com (C)2007
Gross Requirements On-hand Net requirements Netting find net requirement Lotting • find order quantity Offsetting find order time (order release) Explosion calculation to low level MRP steps: • Lot-for-lot (L4L) • Economic order quantity (EOQ) • Fixed Order Period (FOP) • Fixed Order Quantity (FOQ) • Least total cost (LTC) • Least unit cost (LUC) • Part Period Balancing • Wagner-Whitin Algorithm jpsugiono@gmail.com (C)2007
