I would soon be taking an exam for masters course. I need to study the following topics Production Planning and Control: Forecasting models, aggregate production planning, scheduling, materials requirement planning. Inventory Control: Deterministic and probabilistic models; safety stock inventory control systems. Operations Research: Linear programming, simplex and duplex method, transportation, assignment, network flow models, simple queuing models, PERT and CPM. I have been suggested this book Production Operations Management, Buffa & Sarin. I cant find it though. Any other book for this?
