Problem 1 (13 points): Lafayette Furniture refinishes old wood furniture. Their process for refinishing chairs has 9 workers and 4 stages. Each chair starts at the Stripping stage, then goes to Priming, then to Painting and finally to Inspection. Where there are multiple workers with a stage, each worker works in parallel on his/her own chair. Assume inventory buffers are allowed between stations. Stage Stripping Priming Painting Inspection Number of workers 4 2 2 1 Task time per worker in [hours/unit] 2.5 1 2 0.8 Stage Capacity in [units/hour] 1.6 2 1 1.25 a. Fill in the last column of the table. Which stage is the bottleneck and what is the process capacity in [chairs/hour]? (5 points) = Painting / Process Capacity is 1 unit/hr. b. Assume that each day has 8 working hours, and the current production rate is 6 chairs per day. What is the labor utilization? (5 points) c. Suppose now we change the task assignment: each of the 9 workers works independently on a chair from start to finish, i.e., each worker does Stripping, Priming, Painting and Inspection.

Answer rating: 100% (QA)

Part a The bottleneck is Painting so the capacity of the process is 1 unit per hour Part b ... View the full answer
