This chapter include objectives: Describe the project life cycle, discuss the behavioral aspects of projects in terms of project personnel and the project manager, explain the nature and importance of a work breakdown structure in project management, | Manufacturing Planning and Control MPC 6th Edition Chapter 9 Just-in-Time Just-in-time (JIT) approaches to manufacturing planning and control change both manufacturing practices and MPC execution. JIT reduces the complexity of detailed material planning, the need for shop-floor tracking, work-in-process inventories, and the transactions associated with shop-floor and purchasing systems. Agenda Just-in-Time in Manufacturing Planning & Control Resource planning Sales and operations planning Demand management Master production scheduling Detailed material planning Material and capacity plans Shop-floor systems Supplier systems Detailed capacity planning JIT impacts most MPC systems JIT Elements JIT Action Programs Reduced setup times and lot sizes “No defects” goal Improved quality through process improvement Total productive maintenance (TPM) Poka-yoke–foolproof operations Continuous improvement Worker involvement Cellular manufacturing JIT Benefits Reduced throughput time Shorter . | Manufacturing Planning and Control MPC 6th Edition Chapter 9 Just-in-Time Just-in-time (JIT) approaches to manufacturing planning and control change both manufacturing practices and MPC execution.
