Abstract:

The present invention optimizes shop floor operations by generating production schedules that respect the complex manufacturing rules of specified production operations. The invention utilizes attribute-sensitive changeover models that consider both the duration and cost of each changeover. Since the invention considers more than just the item, changeover models can be based at the item level and the item attribute level. The invention includes realistic models that simulate operations for a variety of process and discrete manufacturing work centers and departments. These models support reusable and auxiliary resources, resource groups, user-defined units of measure, detailed bills of material (BOMs), production rate models, and production method models. The sequencing invention can be integrated with other planning optimization systems, including planning and scheduling engines, to provide further shop floor optimization to productively drive the sequencing of a complex business.
