The manufacturer of children's toys designed a special toy truck that can be assembled in 8 basic steps. The required time and predecessors for the tasks can be seen in the table below. There are 7.5 productive hours available in a day and the manufacturer wishes to produce 400 units... Task Time (sec) A amoo - L B D G H 45 50 20 55 15 65 25 35 Predecessor -- A A AD D E B, C, F, G a. Draw the precedence diagram for this process. b. Calculate the cycle time for this process. c. Calculate the theoretical minimum number of workstations. d. Assign the tasks to work stations using the LOT rule. e. The process design team realizes that the potential spike in demand for this device requires increased output. They elect to add a seventh worker to their production team at the first station. What is the net effect of adding this worker? f. Calculate the efficiency of the line. g. Calculate the total idle time.
