Answer:
a. Station Staffing Processing time Capacity
(hours/chair/worker) (Staffing/activity time)
Stripping 3 workers 2.5 3/2.5 = 1.2
Priming 2 workers 1.5 2/1.5=1.33
Painting 2 workers 1.75 2/1.75=1.14
Inspection 1 worker 17/10=1.7 1/1.7=0.59
Inspection have the bottle neck, due to the least capacity (0.59). So, the process capacity can be given as 0.59
Total time to produce first chair =2.5+1.5+1.75+1.7 = 7.45 hours
Total time to make the each subsequent chair will be 1/0.59
b. So, total time to complete 15 chairs = (7.45)+ (1/0.59)*14
= 7.45 + 23.73
= 31.18 hours
c. In this case, there will be no bottle neck as each worker will be operating with its full capacity.
Total time taken by each worker to finish one chair = 2.5+1.5+1.75+1.7 = 7.45 hours & Total workers = 8
Maximum capacity = 8/7.45
Maximum capacity = 1.074 chairs per hour
