5.9 For the process flowchart in Figure 5.12, where the numbers between parentheses are the estimated activity times (in minutes), calculate the average CT.

5.10 Assume that the processing times (in minutes) for the activities in Exercise 5.9 are estimated as shown in Table 5.13. Calculate the CT efficiency.

5.11 Assume that four resource types are needed to perform the activities in the process of Exercises 5.9 and 5.10. The resource type needed by each activity is shown in Table 5.14.

a. Considering that there are two units of resource 1, two units of resource 2, three units of resource 3, and three units of resource 4, calculate the capacity of the process.

b. If the actual throughput of the process is 2.5 jobs/h, what is the capacity utilization?
