1. (TCO 8) Does cellular manufacturing apply best to repetitive, high-volume product or nonrepetitive, low-volume product? Explain and give an example. (Points : 25) 2. (TCO 11) Validate or invalidate the statement that although inventories are maintained, the goal of lean operations is to maintain a minimum of safety stock. (Points : 25) 3. (TCO 9)Elaborate on the statement: “The output of the system cannot exceed the output of the bottleneck operation(s).” (Points : 25) 4. (TCO 4) Differentiate between infinite loading and finite loading as two major approaches used to load work centers. (Points : 25) 5. (TCO 12) Explain why batch process helps maximize worker efficiency. (Points : 25) 6. (TCO 2) Refer to the following data for jobs waiting to be processed at a single work center (jobs are shown in order of arrival):……………………Batch job requires specialized operations carried out by different workers or group of workers and so there is a need for more specialization and standardization. What is the schedule sequence using the first-come, first-served (FCFS) priority rule? (Points : 25) 7. (TCO 10) Respond to the question: “Which is better, MRP or JIT?” (Points : 25) 8. (TCO 1) The design of the MPC system is influenced by some key features of market demand and product design. Name the key features that will lead to a make-to-stock system and explain the rationale. (Points : 25) 9. (TCO 6) Market requirements drive the choice of the shop floor system approach. Describe and explain the type of market requirements that would be suitable for an MRP-based system, along the lines of product design, product variety, and product volume per period, product mix changes, and delivery schedule changes. (Points : 25) 10. (TCO 10) Manufacturing strategy also drives the choice of shop floor system. Describe and explain the strategies that lend themselves to a JIT-based system, from the perspective of WIP, changeover cost, and process choice. (Points : 25)
