work design & measurments

Problem 2 (Problem 3.6 in the Book) A factory is dedicated to the production of one product. One unit of raw material is required for each unit of product. Two processes are required to produce the product, process 1, which feeds into process 2. A total of ten identical machines are available in the plant that can be set up to perform either process. Once set up, each machine will be dedicated to that process. For each machine that is set up for process 1, production rate = 10 units per hour. For each machine that is set up for process 2, production rate = 5 units per hour. Both processes produce 100% good units (fraction defect rate = 0). A work-in-process buffer is provided between the two processes to avoid starving and blocking of machines. The factory operates 40 hours per week. (a) In order to maximize factory production, how many machines should be set up for process 1, and how many machines should be set up for process 2? (b) What is the factory's maximum possible weekly production rate of good product units
