Question

question 3 20 pts there are three improvements that can be made to improve the performance for a line. which of these is not one of those improvements? build buffers to hold excess inventory at bottlenecks make use of parallel machines in place of single machines at workstations reduce the variability of the processing times to less than that implied by the exponential distribution unbalance the line by adding capacity at a station

Explanation:

Building buffers at bottlenecks helps manage excess inventory, using parallel machines can increase capacity, reducing processing - time variability is beneficial, and adding capacity at a station can balance the line. Unbalancing the line by adding capacity at a station is not a typical way to improve line performance as it can disrupt the flow and cause inefficiencies.

Answer:

unbalance the line by adding capacity at a station
