Final answer:

Using Little's Law, the average time a part spends in the workstation is calculated as 3.04 days after rounding to two decimal places.

Step-by-step explanation:

To find the average time a part spends in this workstation, we will apply Little's Law, which is a theorem for queuing theory that states:

L = λW

where:

  • L is the average number of items in the queuing system (average WIP inventory),
  • λ (lambda) is the average number of items arriving at the system per time period (average arrival rate),
  • W is the average time an item spends in the system (average time in the workstation).

Given that the manufacturer's average WIP inventory (L) for Part #1845 is 776 parts, and the workstation produces parts at the rate (λ) of 255 parts per day, we can rearrange Little's Law to solve for W:

W = L / λ

W = 776 parts / 255 parts per day

W = 3.0431 days

Rounded to two decimal places, the average time a part spends in this workstation is 3.04 days.
