The AMP-AKZO company´s simulation-based finite capacity scheduling system

The AMP-AKZO Riverhead Circuits Division is responsible for manufacturing printed circuit boards. Scheduling problems have resulted from both physical and operating constraints. The AMP-AKZO PROVISA Scheduling System (APSS) was developed to better manage order due-date and plant throughput performance. The integrated system is made up of the Production Control Inventory System (PCIS), and the PROVISA scheduling system. The APSS automates the majority of routine scheduling decisions, and provides capabilities to recover from unplanned events, such as machine-breakdowns. Furthermore, the system provides "what-if" analysis capabilities to test scheduling alternatives and opportunities. The APSS is capable of forecasting very accurate schedules and can be used as a continuous improvement tool. Since released to production in February 1994, the scheduling system has improved the company\´s overall scheduling effectiveness. Consequently, AMP-AKZO has reported an increase in both order due-date and plant throughput performance.
