Weighted Average Lead Time (WALT) ( Days )
Let's see if I can still calculate WALT correctly. It's been a while.
1. In Excel make column heading- Item #, lead time (days), Std Cost, Est Annual Usage,Est Annual $, Lead Time X Est Annual $.
2. List all of your SKUs under "Item #" and populate the next 3 colums with respective data from your information system or records.
3. Find your estimated annual $ (spend) by multiplying "estimated annual usage" X "Std Cost".
4. Find LT (lead time) X "Est Annual $" by multiplying those fields.
5. At the bottom of your worksheet, sum "Est Annual $" and "LT X EA $".
6. Divide "LT X EA $" by "Est Annual $" to find your WALT in days.
If anyone sees an adjustment to the logic/ math that needs to be made, please jump in. I'm 98% sure this is the correct way to calculate the WALT. I've nver calcualted WAPT, but I would assume same logic, different variables. Let me know if trhis helps!
这是我从网上查到的,不知道有没有其他的算法。 |
