Consider the process below.

Task	Previous Required Task	Task Time (seconds)
1	--	35
2	1	60
3	2	45
4	1	120
5	4	75
6	4	80
7	3,5	90
8	6	15
9	7,8	40

a) Draw a process flow chart.

You need to generate a throughput of 20 units per hour. What is the minimum number of workers required?

1) 5

2) 3

3) 4

4) 6

Determine an allocation of tasks to an appropriate number of workers that will accomplish an hourly capacity of 20 units, which will also minimize the number of workers needed. Use most following tasks as a rule if you have multiple feasible tasks to assign to a worker. Following tasks are defined as tasks that cannot be completed until the task in question is finished (i.e. 3 follows 2, but 8 does not follow 2). Use longest processing time as a secondary rule (if feasible tasks have the same number of following tasks).

b) Draw a process flow chart of your final process (show the flow by worker with tasks allocated to each).

Which of the following series reflects the correct sequence of processing times in seconds across task bundles assigned to workers?

1) 155, 160, 145, 130

2) 145, 180, 130, 120

3) 155, 155, 120, 130

4) 160, 155, 130, 120

c) After allocating tasks to workers what is your process utilization?

1) 95%

2) 90%

3)75%

4) 80%

5) 85%
