QUESTION 1:A project consists of eight activities denoted by A, B, C, D, E, F, G and H. The activities areplanned to be executed as follows:●●●The project starts with activity A and is expected to take 10 days;When A is completed, Activities E and B may be started, and these are expectedto take 5 days and 9 days, respectively;Activity F may be started when E is completed, and it is expected to take 17daysActivity C, with an expected time of 3 days, depends for its start on thecompletion of F and B;When F is completed activity G may begin and is expected to take 8 days;When C is completed D may begin and is expected to take 15 days; andH may begin when G and D are completed and the expected time for this finalactivity is 7 days.(a) Prepare an activity logic table(b) Develop an AON network for this project. Show all the necessary information onthe nodes.(c) What is the impact of having a lag of 10 days between activities F and G?

Activity A can start as soon as the project starts, and set the earliest start time for activity an equal to 0. With an expected activity time of 5 weeks. Using this information what is the earliest finish time for activity A?
A project has 7 activities P, Q, R, S, T, U, and V. Three time estimates (optimistic, most-likely, pessimistic) are used for each activity. Write down your answers to all parts of the question in the box given below. Give your answer to 3 decimal places. (Note (a) has of 2 parts and (b) has of 3 parts) For activity Q, these time estimates are as follows: optimistic time = 9, most-likely time = 14, pessimistic time = 20. Write down the average activity time for Q the variance of activity time for Q. The critical path of this project has a mean project time of 44 days and a standard deviation of 5 days. Assume project completion time is normally distributed. Find the probability that the project will be completed in 47 days. Find the probability that the project will take more than 40 days. We want to set a deadline for this project completion. If the probability of meeting this set deadline is 0.88, what will be the deadline for this project.

1. A project was planned using PERT with three-time estimates. The expected completion time of the project was determined to be 40 weeks. The variance of the critical path is 9. (e) The project manager wishes to set the due date for the completion of the project so that there is a 90% chance of finishing on schedule. Thus, there would only be a 10% chance the project would take longer than this due date. What should this due date be?

To help with preparations, a couple has devised a project network to describe the activities that must be completed by their wedding date. A project network with 10 activities and 13 directed arcs is shown. Activity Start is connected to activity A and to activity B. Activity A is connected to activity C and to activity D. Activity B is connected to activity E. Activity C is connected to activity H. Activity D is connected to activity F and to activity G. Activity E is connected to activity F and to activity G. Activity F is connected to activity H. Activity G is connected to activity Finish. Activity H is connected to activity Finish. Activity Finish has no arcs directed to other activities. The following table lists the activity time estimates (in weeks) for each activity.

There are four critical paths in a network. A-B-C-D-E, A-F-G-E, A-H-J-K-L-E and A-S-T-E. Each activity in this network can be crashed by 100 hours. The maximum possible reduction in the project duration will be: a. Insufficient information b. 1300 hours c. 500 hours d. 400 hours e. 600 hour
The information below shows the order in which the activities of a project occur along with the time taken for each activity: Q must follow P R must follow P S must follow P T must follow S U must follow S and T V must follow S and T W must follow P, Q, R, S, T , U, V P takes 8 minutes Q takes 6 minutes R takes 6 minutes S takes 3 minutes T takes 3 minutes U takes 7 minutes V takes 7 minutes W takes 18 minutes Construct an activity network to represent the project information given. Include the early start, early finish, late start and late finish times for EACH activity. Hence, determine the critical path for the project.
