tailieunhanh - Lecture Manufacturing planning and control for supply chain management (6th Edition) – Chapter 8

After studying this chapter you will be able to: Describe the type of problem that would lend itself to solution using linear programming, formulate a linear programming model from a description of a problem, solve simple linear programming problems using the graphical method,. | Manufacturing Planning and Control MPC 6th Edition Chapter 8 Production Activity Control Production Activity Control (PAC) concerns the execution of material plans. A number of MPC activities, including Shop-floor Scheduling and Control (SFC), Vendor Scheduling and Follow-up, Order Release, and Purchasing fall partly or completely within the realm of Production Activity Control. Agenda Production Activity Control in the MPC System Resource planning Sales and operations planning Demand management Master production scheduling Detailed material planning Material and capacity plans Shop-floor scheduling and control (SFC) Purchasing Detailed capacity planning Vendor scheduling and follow-up Order release Production activity control System Links–MPC and Production Activity Control Just-in-Time (JIT) Effect on PAC Formal systems for shop-floor control are largely unnecessary under JIT PAC functions are simplified Order release through kanbans or other pull system Limited work-in-process . | Manufacturing Planning and Control MPC 6th Edition Chapter 8 Production Activity Control Production Activity Control (PAC) concerns the execution of material plans.
