JSC Gantt Chart (tisfc1126m000)

The graphical planning board can be used in a job shop environment, and has two views:

• Gantt view

  An overview of the production orders on the job shop.

• Schedule view

  An overview of production order operations planned by work center or machine. In the appropriate menu, click View by WC/Machine to switch between the operations by work center and the operations by machine.

Note that the planning board displays calendar days, not working days.

To view and plan production order operations

In the graphical planning board, you can view and plan the production order's operations. To view the operations for a production order in the Gantt view, you must first double-click the production order in the left column so that the order expands. The operations, in the Gantt view as well as in the Schedule view, can provide you with the following extra information:

• Completion percentage

  You can view the progress on a production order operation indicated by a progress bar and a completion percentage. If you click Show completions in the View menu, you can display or hide the progress bar and the percentage .

  LN uses the following formula to calculate the progress bar's length:

  Planned production time - Remaining production time / Planned production time

  In other words, the progress bar indicates which part of the setup time and the production time is already finished. The queue time, wait time, and move time are not included in the progress calculation. Note that although part of the progress bar can be displayed underneath the operation's wait time in the planning board, the wait time is not taken into account in the progress calculation.

• Overdueness

  An operation is overdue if the operation's end time is later than the production order's requested delivery date. If you point the cursor to an operation that is overdue, the overdueness is displayed in calendar days/hours as well as in working hours. Overdueness of an operation can be indicated by the color. If the color of the operation is red, the operation is overdue. In the appropriate menu, you can click Switch 'Display Overdue' on/off to determine whether LN must use color to display that an operation is overdue.

• Leadtime components

  The operations' leadtime components, such as the queue time and the setup time, as well as the operations' statuses are indicated by colors.

You can drag and drop the production operations in the graphical planning board to replan your production. The production planning data is then updated in LN. Replanning in the graphical planning board uses the same planning logic as the LN planning sessions.

It makes no difference whether you drag an operation block at the front or at the back of the block. Even if you drag an operation block at the end of the block, the change is expressed in the operation's start time. LN then plans forward on the basis of the new start time to calculate the new end time of the operation. The dates and times of the other operations in the production order change dependent on the production order's moving methods.

If you double-click a production order or an operation, the Production Order (tisfc0101m100) session or the Production Planning (tisfc0110m000) session are respectively started, in which you can view and/or maintain planning data. You cannot add or append new operations in the planning board. You can, however, change dates and operation times.

Menu options

In the Gantt view, use the commands in the appropriate menu to sort the production orders. By sorting your data, you can focus on a specific part of the job shop, for example, view the production orders for a specific PCS project or production start date.

You can choose whether a message must be displayed if replanning causes a production order to be late. In the appropriate menu, click Switch 'Planning Messages' on/off to determine whether a message must be displayed.

You can choose whether operations with the Completed status must be displayed in the planning board. In the appropriate menu, click Switch 'Skip Completed' on/off to determine completed operations must be displayed.

You can choose whether you want to display the operation's queue time by clicking Switch 'Display Queue Time' on/off in the appropriate menu. If the queue time is displayed, the start date of the operation block in the planning board equals the queue time's start date. If the queue time is not displayed, the start date of the operation block equals the date of the setup time or run time.

From the appropriate menu of the planning board, you can also start the following sessions:

• Production Orders (tisfc0501m000)
• Production Planning (tisfc0110m000)
• Automated Queue Time Compression (tisfc1103s000)
