1. As shown below, three batch processes producing products A, B, and C use the same pieces of equipment in the same sequencing but for different times. Equipment Product A Product B 1.5 1.0 1.5 2.5 2.5 4.5 2.5 1.5 Mixer Reactor Separator Packaging Product C 1.0 4.5 3.5 2.0 For this process, answer the following problems: a. We want to run a campaign for 500h using the following sequence of products: AABCCCAABCCCAABCCC..... Draw an accurate Gantt chart that clearly shows the timing of all equipment for each product. From this chart determine the cycle time for the system (i.e., time taken to complete the following sequence of batches AABCCC) and then find the number of batches of A, B, and C produced in 500h. b. Repeat the problem but now use the sequence BAACCCBAACCC..... Does your answer change from part a. c. What is the solution to the problem if separate, single-product campaigns for A, B, C (with the same ratios as in the above problems) are used?
