A company has five machines (1 lathe, 2 mills and 2 drills) arranged sequentially to produce a batch of 200 parts. The following table lists the setup and work cycle times per piece for the five machines. 1. Delay hr) 10 10 10 10 10 Machine Setup time (hr. 2.50 1.25 1.50 0.50 0.75 (min) 15 27 12 1. Lathe 2. Milling (V) 3. Milling (H) 4. Drill (i) 5. Drill (ii) Management wants to procure a multitasking machine to replace the five machines. This new m achine would complete the batch of 200 in one setup. The setup time would be 2 hours and the delay would be 10 hours for the multitasking machine. Determine: (a) The manufacturing lead-time (how long it takes to complete the batch of 100 parts, including delays) for the five conventional machines and (b) The manufacturing lead-time for the multipurpose machine.
