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$).$

What is the WIP level in the line?

What is the cycle time as a percentage of T$0?$

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

Increase the WIP level

Decrease the variability of one station

Decrease the capacity at one station

Increase the capacity of all stations
