Abstract : |
Production management involves planning, scheduling and control. Whereas mrp-ii systems have contributed greatly to production planning, detailed scheduling and control remain problematic and have proved a significant research challenge. tosca is a research and development programme which provides an overall framework for production planning, scheduling and control based around representations of factory resource and setup capacity. Up to this time, work on tosca has concentrated on predictive scheduling focusing on (i) representations for capacity and setup constraints and objectives, (ii) methods to monitor the criticality of these constraints during scheduling, and (iii) methods to allow critical constraints to be effectively managed to enable good solutions to be achieved. Current research on tosca is investigating re-scheduling and methods of schedule repair following shop-floor feedback., |
