Exercise 4.6 Performance analysis II

Consider the process in figurę 4.47.

(a) Determine the following performance indicators:

*    Occupation ratę (utilization) for each resource,

*    Average WIP (work in progress),

•    Average flow time (throughput time), and

•    Average waiting time for each task.

The two resources working on task 1 join forces and work together on both easy and difficult cases. As a result the average time to handle task 1 for one case is two minutes (i.e., a total of 4 minutes of capacity).
