A project consists of 8 activities. The activity completion times and the precedence relationships are as follows: Activity. Completion time Days. immediate predecessor activities.

A. 5 -
B. 7 -
C. 6 -
D. 3 A
E. 4 B, C
F. 2 C
G. 6 A, D
H. 5 E, F

1. Draw the network diagram using AON model notations:

2. What is the critical path?

3. Calculate: Early Start, Early finish, Late start, Late finish, slack, critical path.

4. What is the minimum time to complete the projects?

1. If activity E is delayed by 3 days how is the project completion time affected? Why is this the case?

2. If activity F is delayed by 3 days how is the project completion time affected? Why is this the case? Will the critical path change, why or why not?

3. If you want to shorten (crash) the overall time of this project, how do you pick which activity to shorten? What information, if any, do you need?

4. Once you shorten (crash) an activity, do you need to redo the AON, yes or no? Why or why not?

Jason, samantha, ravi, sheila, and ankit are preparing for an upcoming marathon. each day of the week, they run a certain number of miles and write them into a notebook. at the end of the week, they would like to know the number of miles run each day, the total miles for the week, and average miles run each day. write a program to them analyze their data. your program must contain parallel arrays: an array to store the names of the runners and a two-dimensional array of five rows and seven columns to store the number of miles run by each runner each day. furthermore, your program must contain at least the following functions: a function to read and store the runners’ names and the numbers of miles run each day; a function to find the total miles run by each runner and the average number of miles run each day; and a function to output the results. (you may assume that the input data is stored in a file and each line of data is in the following form: runnername milesday1 milesday2 milesday3 milesday4 milesday5 milesday6 milesday7.)
