Calculate Lead Time

Explanation

This activity is used to calculate a part's order manufacturing lead time. The manufacturing lead time is calculated from the default routing and lot size of the part; it considers the setup, move, operation times, and the efficiency factor entered for the operation. The system also considers information abut queue time and shifts, i.e., the number of work hours per day from the work center where the operation is performed. You specify whether you want to run the calculation for one part at a time or for all parts in a specific site.

Prerequisites

This activity requires that a part must be defined with a routing.

System Effects

As a result of this activity:

• The system calculates the manufacturing lead time for a part or parts on a site.
• The system updates these lead time values on the Inventory Part/Manufacturing tab in IFS/Inventory.

Procedure

You can either calculate the lead time directly (Procedure A), or schedule the task as a background job (Procedure B).

A. Calculate the lead time directly:

1. Open the Lead Time Calculation dialog box.
2. In the Site field, select the site for which you want to run the calculation. Use the List of Values to select from available sites.
3. If you want to calculate the manufacturing lead time for a specified part, select the part in the Part No field. Use the List of Values to select from available parts. If no part is selected, the calculation is done for all parts in the site.
4. In the Update Options list, select the suitable option. Possible values are Update, Do not update and Update also expected.
5. Click Controls. The Controls for Calculate Manufacturing Lead Time dialog box opens.
6. In the Capacity area, select the required option. The available options are Average and Demonstrated.
7. In the No Routing Option area, select a required option to determine what can be done if a default routing does not exist for the part. The available options are Leave Unmodified and Set to Zero.
8. In the Leadtime Calculation Basis area, select a required option to determine the lead time for the part.
9. Click OK to close the Controls for Calculate Manufacturing Lead Time dialog box.
10. Click OK to close the Lead Time Calculation dialog box.

B. Calculate the lead time via a scheduled task

1. On the Lead Time Calculation dialog box, click Schedule. The Create New Task Schedule window opens.
2. Set the relevant scheduling parameters and Save. Scheduled tasks can be seen in Scheduled Database Tasks window.
