Consider an assembly line with 3 sequential operations A, B, and C with processing rates 10, 40, and 30 parts per hour, respectively. Suppose there is on dedicated worker for A and B (Abe) and one dedicated worker for C (Chris). However, both workers are perfectly cross-trained.

(a) What is the process capacity in parts per hour?

(b) Suggest a way of reassigning tasks to be Abe and Chris so as to maximize the process capacity. What is the maximum process capacity?

(c) What is the cycle time of the process on a day when Chris is absent, and Abe is the only worker?

Please don't copy and paste the other answers from Chegg, they are wrong.
