Demand for the popular water toy Sudsy Soaker has far exceeded expectations. In order to increase the availability of different models of the toy, the manufacturer has decided to begin producing its most popular models as often as possible on its one assembly line. Given monthly requirements of 7200, 3600, and 3600 units for Sudsy Soaker 50, Sudsy Soaker 100, and Sudsy Soaker 200, respectively, there are 30 working days per month and eight working hours per day. a. Assume that the time required to assemble each model is approximately the same, determine a model sequence for the final assembly line that will smooth out the production of each model. b. If number of changeover (at the beginning of cach day and before producing the different model) for each model is equal in each day of 8-hour and the unit processing time with setup time are as the following figures Changeover time (mins) Model Processing time (mins) Sudsy Soaker 50 0.25 Sudsy Soaker 100 0.3 Sudsy Soaker 200 0.2 60 70 30 i. Determine batch size for each model III. Identify idle time of the assembly line Propose five activities for those times that the assembly line is not processing or changing-over
