Consider the following process. For each station, p is the average process time (days), m is the number of servers, and Rp is the total capacity rate of each station (unit/day). Assume that the final assembly (Station 4) requires one part from Path 1 and one part from Path 2 to complete one finished product.

a) Suppose that jobs are released to Station 1 at the rate of 0.9 parts per day, and the inter-arrival time distribution has a coefficient of variation CVa= 1. The coefficient of variation for Station 1s processing time equals CVp= 1. Compute the average delay that a job would experience at Station 1 and the average number of units in the highlighted buffer (the one before Station 1).
