Question
Furniture Face Lift refinishes old wood furniture. Their process for refinishing chairs has 9 workers and 4 stations. Each chair starts at the Stripping station, then goes to Priming, then to Painting and finally to Inspection. Where there are multiple workers within a station, each worker works independently on his/her own chair. Assume inventory buffers are allowed between each station.

Suppose at the start of the day there is no inventory of chairs in the shop. That is, there are no chairs within any of the stations or between them in any buffer. A truck loaded with 10 chairs arrives. How many hours will it take them to complete these 10 chairs?(The accuracy should be of two digits after the decimal places.)
Please share the explanation.

Explanation / Answer
Station
Staffing
Processing time (hours per chair per worker)
Capacity = Staffing /Processing time

1/0.8=1.25
As stripping has the lowest capacity, thus it will be having bottleneck, therefore the process capacity is 1.2
Total time to produce the first chair =2.5+1.5+1.75+0.8=6.55 hr
Time to produce subsequent chai = 1/1.2=0.83 hrs
So total time taken to produce 10 chairs = 6.55+0.83*9 =14.02 hours
