Planning production orders in JSC
Production order planning provides the facility to modify and preplan the production order. The planning is a process of determining the start and end dates of the individual operation and production order. When the production order is planned, the lead-time of the operations and the production order is calculated. The load on the corresponding machines and work centers is also calculated and displayed.
Production orders can come to the Job Shop Control module from a variety of Origin of production orders including:
- Enterprise Planning
- Warehousing
- Configurator
You can also create production orders manually in the Production Orders (tisfc0501m000) session.
Orders generated by Configurator are normally used only for assembly lines, but you can use the sessions covered in this topic to adjust the planning of operations carried out at non-assembly line work centers after the assembly line. These are known as post-process operations. You can use these, for example, to customize products for customers that require extra features.
However, you might want to modify the planning of these orders in the job shop, for example to cope with a backlog, or an order gaining a higher priority because of customer demand for the end item.
Overview sessions
The Utilization by Week (tisfc1502m000) session gives an overview of each week of what capacity you have planned to use, including:
- planned orders
- work centers and operations for the orders
- quantities planned for the orders
- estimated production time to complete the orders.
If you have selected the Update Method Day Utilization check box in the Production Order Parameters (tisfc0100s000) session, you can use the Utilization by Day (tisfc1503m000) session to give similar information to the above session.
You can also see a similar overview organized by work center or machine and by week or day in the following sessions:
- Work Center Utilization by Week (tisfc1501m000)
- Work Center Utilization by Day (tisfc1506m000)
- Machine Utilization by Week (tisfc1504m000)
- Machine Utilization by Day (tisfc1505m000)
Editing Job Shop Planning
A production order has one or more operations planned. You can alter the order in which the operations are carried out, in the Operation Relationships by Order (tisfc1102m000) session. You can use the Production Planning (tisfc0110m000) session to modify the network routing for one operation, by changing the Next Operation and the Task assigned to the current operation.
To change the dates for the uncompleted operations of several production orders collectively, use the Shift Production Planning (tisfc1202m000) session. You select the earliest operation that is not yet completed, and adjust its Shift Planning to Date. LN adjusts the dates of the other operations in that production order, and of the other production orders that you have selected, to take account of your change.
If you want to change the dates of an individual operation, you can use the Production Planning (tisfc0110m000) session. You can alter several variables, including:
- Remaining Production Time (if you change this, other dates for the operations are updated by LN
- Cycle Time (min) and Average Setup Time
- Production Rate unit time
You can also adjust the Shift Planning to Date by starting the graphical planning board from the Production Planning by Planning Board (tisfc1120m000) session. This lets you reschedule operations by dragging a graphical representation of them with your mouse. You can see a graphical representation of machine planning with the Machine Planning by Planning Board (tisfc1140m000) session and of work center planning with the Work Center Planning by Planning Board (tisfc1130m000) session.
If you discover that your scrap or yield is different from expected, you can also modify this in the Production Planning (tisfc0110m000) session, and LN will modify the planned quantities to take account of your changes.
After you have made changes to the BOM or routing, you will need to use the Reprocess Production Orders (tisfc1203m000) session to make new production orders to take account of the changes you have made.
