SH-M  Lead Time Estimator

Purpose of Program

Use this program to get estimated delivery dates on any item number.  The most common use of this program is for quoting realistic delivery dates to customers or prospects.

The program calculates the projected total run time days for the quantity entered, which includes production setup and run time, outside processing lead time, and any work center queue time.

Work center queue time represents an estimate as to how much contention (waiting time) there may be at each work center.  You can establish different queue times for each work order priority code; in other words in a given work center priority 1 work orders may only have to wait a day, but priority 3 work orders may have to wait 3 days.  Work center queue times are entered in RO-C, Enter Work Centers.

The program then takes the Start Date you have entered, adds the projected total run time days, skips over any non-working days (as defined on the shop calendar), and projects an Estimated Finish Date for each work order priority code.

For comparison purposes, the program also displays a projected Finish Date with no queue times included so that you can see the relative effect of queue time on the projections.  Keep in mind that this program estimates the lead time of the item specified based on its routing and does not include the manufacturing time for lower level subassemblies.

General Program Operation

Enter the item number or select one from a lookup window by pressing the F2 key (or clicking on the Lookup button).  The description will automatically be displayed.  Enter the quantity you plan to manufacture and a work order start date.

The program will then display an Estimated Finish Date for each of the three priority codes and for no queue time.
