(25 points) Consider a worker-machine system that consists of external manual work elements (E), machine work elements (M) and internal manual elements (1). Normal times of E. Mand I are 2.25,2.05 and 2.25 minutes, respectively. Assume PFD allowance factor as 15 9 and a machine allowance factor as 10 %. a. (3 points) The standard time for the cycle is minutes. b. (3 points) Number of work units produced daily (in 8-hour shift) at standard performance is C. (3 points) The worker efficiency given that the worker produces 100 units is 96. Fahrettin is a talented engineer and may increase the productivity of the worker-machine system. He internalized some of external work elements partially, which sums up to a total of 0.35 minutes. Under this new setting, E decreases by 0.35 minutes and I increases by 0.175 minutes. d. (6 points) Under this new setting, the standard time for the cycle is minutes. e. (6 points) Number of work units produced daily (in 8-hour shift) at standard performance under this new setting is f. (4 points) Cost of applying Fahrettin's improvement requires about a 1150 work units production. Therefore, the application cost will pay back in days
