Problem 4 Consider the following 2 machines: .

Problem 4 Consider the following 2 machines: . Machine 1: flexible - requires no setup Has somewhat variable natural processing time - mean natural processing time to = 1.2 hrs. - C.V. of nat. processing time co = 0.5 Machine 2: Needs setup on the average of every 10 jobs, i.e. Ne = 10 jobs. Has somewhat less variable natural processing time - mean natural processing time to = 1 hrs. - C.V. of nat. processing time co = 0.25 Mean setup time = 2 hrs. C.V. of setup time = 0.25 Question a: What is the mean effective processing rate for each machine? Question b: Which machine has a lower coefficient of variation of effective processing time
