Production Scheduling System with Dynamic Lot Size in Case of Considering Set-up Time

Abstract

The dynamic scheduling management system architecture that is based on the parts and information packets unified technology is developed, and variable lot size production with the parts and packets unified technology is proposed. We assumed that each part or unit has a data career, which handle such as identification number, position of the part, state of the part. Using these data, progress of the project process is compared with the master schedule. If the difference arises between them, scheduling system dynamically reschedules with dynamic lot size to optimize the processes. A pilot system that realized our proposal is developed.
