Consider a balanced line consisting of five single-machine stations with exponential process times. Suppose the utilization is 75 percent and the line runs under the CONWIP protocol (i.e., a new job is started each time a job is completed).

(a) What is the WIP level in the line?

(b) What is the cycle time as a percentage of T₀?

(c) What happens to WIP, CT, and TH relative to the original system if you make each of the following changes (one at a time)?

(i) Increase the WIP level

(ii) Decrease the variability of one station

(iii) Decrease the capacity of one station

(iv) Increase the capacity of all stations
