QUESTION 3 (PERT) The construction of a cottage requires the performance of certain activities. The following table, lists the various activities with their priority relationship. Activity | Immediate predecessor | Duration (weeks) | Variance --- | --- | --- | --- A | - | 5 | 0.11 B | - | 8 | 0.44 C | A | 6 | 0 D | B | 4 | 0.11 E | B | 3 | 0.11 F | C,D | 10 | 0.44 G | E | 7 | 0.11 H | C,D | 14 | 1.78 I | F,G | 12 | 0.44 a) Find the critical path b) Find the probability that all critical activities will be completed in 8 months 3 weeks and give a comment.

Step 1
First, we need to find the critical path. To do this, we need to calculate the earliest start time (EST), earliest finish time (EFT), latest start time (LST), and latest finish time (LFT) for each activity. Show more…

A partially solved PERT problem is detailed in the table below. Times are given in weeks. a) Calculate the expected duration (D), and variance of each activity. b) Calculate ES, EF, LS, LF, S for each activity.

2. A project has the following activities, precedence relationships, and time estimates in weeks: Activity | Immediate Predecessor Activities | Optimistic Time (a) | Most Likely Time (m) | Pessimistic Time (b) --- | --- | --- | --- | --- A | — | 15 | 20 | 25 B | — | 8 | 10 | 12 C | A | 25 | 30 | 40 D | B | 15 | 15 | 15 E | B | 22 | 25 | 27 F | E | 15 | 20 | 22 G | D | 20 | 20 | 22 a. Compute the expected time and variance for each activity. b. Determine the critical path and the expected duration of the project. c. What is the probability that the project will take longer than 56 weeks to complete? d. What is the probability that the project will be completed in less than 54 weeks?

A PERT project has 45 activities, 19 of which are on the critical path. The estimated time for the critical path is 125 days. The sum of all activity variances is 64, while the sum of variances along the critical path is 36. What is the probability that the project can be completed in more than 108 days? 0.9825 0.0023 0.0227 0.9977 0.9773
