The task times, shown in minutes, are the times that it takes one worker to perform that task for one unit of product. This line is staffed with six workers, two of whom are assigned to workstation D. Assume that each of the tasks (tasks A through E) are never split among multiple workers. Thus, the two workers doing task d work on individual units, each doing all of task D on the particular unit on which he or she is working. Assume that there is ample equipment so that all workers can perform their tasks. 5) Refer to the Process Diagram for a Five-Task Line. What is the throughput time in minutes)? (3 points) 6) Refer to the Process Diagram for a Five-Task Line. Assume that there are only two costs: each worker receives wages of $10 per hour, and material cost is $15 per unit. Every unit produced generates $36 in revenue. Assume that every unit produced can be sold and that production is steady. What is the contribution (revenue -costs) per unit? (4 points) 7) Refer to the Process Diagram for a Five-Task Line. One of the two workers assigned to task D is equally competent at task C, and it is decided that this worker will work on both tasks C and D. (i.e., one worker is assigned to task C, one worker is assigned to task D, and one worker moves between tasks C and D.) This third worker moves between task C and task D to maximize the output of the process. What is this line's capacity, in units per eight-hour day? (4 points)
