Using simulation-based finite capacity planning and scheduling software to improve cycle time in front end operations

Abstract

This paper instructs the readers in the practical application of simulation-based, multiple criteria dispatching to the semiconductor front end capacity planning and scheduling problem. Many finite capacity planning and scheduling software systems allow rules to be defined by which machines choose tasks to be performed. The session shows why it is critical for companies to have the ability to develop custom coordinated rules to improve the flow of material through a factory by keeping highly utilized machines busy and allowing feeding machines to sequence work in an intelligent manner. In addition, coordinated rules can consider down stream machine congestion. The paper highlights the use of this technology as it is being applied within SGS-Thomson Microelectronics.
