Double-Click to Schedule

摘要

Schedulers have been a part of enterprise resources planning (ERP) and manufacturing resource planning (MRP II) software systems for many years. Recently, new technology is offering increasingly sophisticated systems that apply advanced logic to the scheduling process. However, many companies still find their systems are unable to come up with a schedule that maximizes use and efficiency while ensuring that all work is completed on time. The traditional ERP or MRP II planning processes used bills of material, inventory, and due dates from the master schedule to lay out a production plan. It then was the job scheduler's role to add the operations dates at work centers using an approach called infinite-capacity logic, also known as infinite-loading logic. These terms refer to a model for required capacity that is calculated without regard for actual capacity available to perform the work. Through capacity requirements planning, the load-versus-capacity profile for each work center was generated, enabling operations managers to anticipate and hopefully resolve any mismatches before they caused problems.
