The CPM network with activity times in weeks is given below. How many weeks will the project take to complete?

The following activities are part of a project to be scheduled using CPM. Draw the network.

The scheduled arrival time for a daily flight from Boston to New York is 9:25 am. Historical data show that the arrival time follows the continuous uniform distribution with an early arrival time of 9:15 am and a late arrival time of 9:55 am.

a. Calculate the mean and the standard deviation of the distribution.

b. What is the probability that a flight arrives late (later than $9: 25 \mathrm{am}$ )?

Which of the following correctly describes the focus of the Critical Path Method (CPM)?

A) To determine when a project should be completed and to schedule when each activity in the project must begin in order to keep the project on schedule
B) To order activities in a project in terms of their completion time to facilitate the scheduling of the activities
C) To structure the activities of a project in order to eliminate or reduce critical dependencies among the activities
D) To estimate the probability of completing a project by a given deadline when the time required to perform the activity is essentially a random variable

The following activities are part of a project to be scheduled using CPM:

a. Draw the network.

b. What is the critical path?

c. How many weeks will it take to complete the project?

$$\begin{array}{clc} \text { Activity } & \text { Immediate Predecessor } & \text { Time (weeks) } \\ \hline \text { A } & - & 6 \\ \text { B } & \text { A } & 3 \\ \text { C } & \text { A } & 7 \\ \text { D } & \text { C } & 2 \\ \text { E } & \text { B, D } & 4 \\ \text { F } & \text { D } & 3 \\ \text { G } & \text { E, F } & 7 \end{array}$$

d. How much slack does activity B have?

a. Draw the network.

b. What is the critical path?

c. What is the expected project completion time?

d. What is the probability of completing this project within $16$ days?

Assume the network and data that follow. If the indirect costs for each project duration are $\$400$ (18 weeks), $\$350$ (17 weeks), $\$300$ (16 weeks), $\$250$ (15 weeks), $\$200$ (14 weeks), and $\$150$ (13 weeks), what is the total project cost for each duration? Indicate the minimum total project cost duration.
