Work Order Finite Scheduling – A summary of the activity

Finite scheduling involves scheduling of work orders by considering one work order at a time and start scheduling the next work order upon completion of first work order. You can select the material/production controller and the sequence rule codes that represent the priority, start date and end date based on which the work orders are scheduled. The other rule codes details include slack time and critical ratio along with the total and balance operation time. You can display the work orders based on the date ranges specified in the work order sequence criteria header. You can sequence the work orders on selecting the work in progress for which production updates are reported.

The scheduling of the work orders can be started based on the MRP date or on the base date. If the MRP date is selected, then the work orders are scheduled based on the MRP generated start date. If the base date is selected, then the system schedules the work orders based on the base date specified. For example, if WO1 has start date as “08/12/02” and the current date is “10/12/02”, then the work order can be scheduled on “10/12/02” that is, the current date instead of considering the MRP generated date. In the above case base date is specified as the current date. Otherwise, you can select the MRP generated date. You can specify a new scenario for each of the sequence rule code modified or can retrieve the sequence rule code details for the scenario already defined.

You also have an option to select an alternate resource if the current resource cannot be utilized for the work order. For the details specified in the sequence criteria and the work order sequencing details, the corresponding work orders that match the criteria are retrieved accordingly in the multiline.  On submission, all the work orders displayed in the multiline are scheduled for the start by date (if any) specified in the multiline. The date is checked against the MRP date and base date, and is scheduled accordingly. For example, if there are 10 work orders (WO1 to WO10) displayed in the multiline with their corresponding resources and activities. The system may schedule each work order one after the other and continue until the last work order in the multiline. You can schedule the work orders either in online or batch mode of execution.
