- Alocal toy manufacturer is using a production line that runs 8 hours per day and produces a toy that requires a total of 7 tasks to be performied. The daily demand is 150 toys. Times of the tasks are 2.73, 2.01, 2.13, 2.0, 2.61, 2.71, and 2.95 minutes for A, B, C, D, E, F, and G, respectively. However, due to the nature of the product there are precedence rules that must be observed. Such that Task A does not need any predecessors; task B requires taskA to be completed. To start task Cand task D, each require task B to be completed. Task C must be completed prior to stating task E. Task F needs both task D and task Eto be completed. Finally, task G can start only once taskFis completed.What is the minimum number of workstations needed?arrow_forwardThe Mowry Machine Shop still has five jobs to be processedas of 8 a.m. today (day 23) at its bottleneck operation.
