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?

Waldorf Astoria Spa & Health Club at Waldorf Astoria Chicago offers high-quality hair-styling and physical relaxation services at a reasonable price, so it always has unlimited demand. The process comprised of five tasks that are completed in the sequence described below. (The time required for each task is shown in parenthesis). Task 1: Welcome a guest and offer homemade herb tea (10 minutes) Task 2: Wash and condition hair (10 minutes) Task 3: Neck, shoulder, and back stress release massage (10 minutes) Task 4: Design the hairstyle and do the hair (25 minutes) Task 5: Check out the guest (5 minutes) Three servers (S1, S2, and S3) offer the services in a worker-paced line. The assignment of tasks to servers is the following: S1 completes Task 1. S2 completes Tasks 2 and 3. S3 completes Tasks 4 and 5. Assume a wage rate of $18 per hour.
