Repetitive Production SchedulingA production schedule is built from multiple runs of schedule lines, based on the item order plan in Enterprise Planning. The original start date and end item of all the schedules lines from one run is the same. The runs are distributed over the available work cells based on the work cell's calendar in combination with the need by date of the schedule line. Depending on the settings in the Repetitive Manufacturing Parameters (tirpt0100m000) session, scheduling can be fully automated, or manually adjusted. Repetitive manufacturing uses schedule lines to plan manufacture of items. Planning and scheduling happens on several levels to manage all aspects of repetitive manufacture:
Production scheduling After an item order plan is generated in Enterprise Planning a production schedule can be generated in the Repetitive Manufacturing planning engine. Depending of the schedule horizon of the item order plan, two different types of supply are generated.
The list of materials, which is defined in the production model of the repetitive item that is planned, is used to generate the dependent demand for the materials. Exception messages are used to report any errors that occur during generation of production run schedule. Error in the planning, rescheduling, and cancellation messages for Active run schedule lines are generated when conflict in planning must be resolved. In the Work Cell Planning (tirpt4102m210) session it is possible to manually adjust the generated production schedule: add and change new schedule lines, and adjust the status of existing lines. After rescheduling is completed, the production run schedule is rebuilt with the changes you specified from the input start date based on the availability of the related work cell. After the schedule is complete, schedule lines must be released to trigger the start of production. This can be done either in the Release Production Schedule Lines (tirpt4202m100), Work Cell Group Planning (tirpt4602m200) or the Work Cell Planning (tirpt4102m210) sessions by selecting the relevant schedule lines and using the relevant command. Once the schedule lines are released, production can begin. Example Item A is a manufactured item. To produce item A, one item B is required. Item B is a purchased item. There are several independent demands for item A.
