Global competition has engendered a trend among companies towards continuously improving operations so that they can provide customers the right products in the right quantities at the right times. In modern manufacturing, the trend is the development of Computer Integrated Manufacturing, CIM technologies which is a computerized integration of manufacturing activities (Design, Planning, Scheduling and Control) produces right products at right time to react quickly to the global competitive market demands. The productivity of CIM is highly depending upon the scheduling of Flexible Manufacturing System, FMS. Shorting the make span leads to decreasing machines idle time which results improvement in CIM productivity. Conventional methods of solving scheduling problems based on priority rules still result schedules, sometimes, with significant idle times. To optimize these, this book model the problem of a flowshop scheduling with the objective of minimizing the make span. The work proposed here deal with the Production Planning Problem, PPP of a FMS. PG-Engineering students and Engineers will find this book beneficial as a source material to solve Production Planning Problem of a FMS.
