Note: Please show work clearly and do not copy and paste solution from a different page. I have been noticing that multiple times for similar problems. Show work and explain steps, particularly for problem B and D

Casey Belzer runs a small machine shop that fabricates parts for sprayers used in foam insulation equipment. With the renewed interest in green building practices and high energy costs demand for his products has increased dramatically. The shop has three CNC machines that can serve a variety of purposes. As customer orders come in, a routing sheet is developed and the order is diagrammed as shown below. When demand was low, it didn't really matter how the jobs were scheduled. Now, Casey wants to finish each job as quickly as possible so he can move on to the next one. Help Casey develop a schedule that would finish customer order for 200 units of part A as soon as possible. Assume one B, C, and D are needed for each A.

a) Which resource is bottleneck?

b-revised: Discuss which job(s) is eligible to be first scheduled for the bottleneck machine(resource), and which job(s) is not eligible to be first scheduled? Be specific with the jobs. Ex: C1, D2, D3

Job(s) eligible to be first scheduled:

Job(s) NOT eligible to be first scheduled:

d) Map out the optimum schedule on a Gantt chart. What is the completion time? Assume that the process batch size is 200 and the transfer batch size is 1. Mark all times on your Gantt chart clearly. Please describe step-by-step process on how to create chart and format it
