Machines and Accessories

New Types of Factory Layout

Three approaches to layout design address three distinct

needs of the flexible factory.

The first two approaches present novel layout configurations,

namely distributed and modular layout.

In the third approach, we use operational performance as a

design criterion to generate what term agile layout.

Unit 2 Manufacturing Resources Planning 2 Master Production Scheduling

The mater production scheduling is effectively the company has developed for production, staffing , inventory, etc.

The production plan may be broken down into several component parts:

The master production scheduling (MPS)

The material requirements planning (MRP) system The detailed job shop schedules.

At the heart of the production plan are the forecasts of demand for the end items produced over the planning horizon .
