Help please The table below defines the precedence relationships and element times for a new modeltoy. (a) Construct the precedence diagram for this job. (b) If the ideal cycle time = 1.1 min.repositioning time = 0.1 min, and uptime proportion is assumed to be 1.0, what is the theo-retical minimum number of workstations required to minimize the balance delay under theassumption that there will be one worker per station?

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 performed. The daily demand is 100 toys. Times of the tasks are 2.73, 2.01 201 2.13, 2.0, 2.61, 2.71 , and 2.95 minutes for A,B,C,D,E,F, and respectively. However, due to the nature of the product there are precedence rules that must be observed. Such that Task Adoes not need any predecessorsB requires task A to completed. To start task C and task Deach 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.
