- Your project to obtain charitable donations is now 30 days into a planned 40-dayproject. The project is divided into 3 activities. The i rst activity is designed to solicitindividual donations. It is scheduled to run the i rst 25 days of the project and to bring in $25,000. Even though we are 30 days into the project, we still see that we have only 90 percent of this activity complete. The second activity relates to company donations and is scheduled to run for 30 days starting on day 5 and extending through day 35. We estimate that, even though we should have 83 percent (25y30) of this activity complete, it is actually only 50 percent complete. This part of the project was scheduled to bring in $150,000 in donations. The i nal activity is for matching funds. This activity is scheduled to run the last 10 days of the project and has not started. It is scheduled to bring in an additional $50,000. So far $175,000 has actually been brought in on the project. Calculate the schedule…The project manager must make trade-offs between project progress and process. Conceptually, this involves trade-offs between the __________ functions. a. schedule and cost b. technical and managerial c. cost and performance d. performance and scheduleA project consists of the following activities, with the duration, in weeks, of each activity given in brackets. A(6), B(4) and C(7), the first activities of the project, can be executed concurrently. A and B precede D(2). B precedes E(1), F(5) and H(8). F and C precede G(3). E and H precede I(2) and J(4). C, F and J precede K(2). K precedes L(4).D, I, G and L are the terminating activities if the project. Construct the precedence table, and hence draw the network for the project
- 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 hourPERT analysis computes the variance of the total projectcompletion time as:a) the sum of the variances of all activities in the project.b) the sum of the variances of all activities on the criticalpath.c) the sum of the variances of all activities not on the criti-cal path.d) the variance of the final activity of the project.A project consists of three tasks: A, B, and C. Task A is known to take five days forsure. Tasks B and C are each dependent on A. B takes five days. C takes seven dayswith a probability of 0.5 and three days with a probability of 0.5. What is the expectedcompletion time of the project?a. 8 daysb. 10 daysc. 11 daysd. 12 days
- You are provided with the following information for a project, with activity durations given in weeks: Activity Immediate Optimistic Most Likely Pessimistic Predecessor Time (a) Time (m) Time (b) A ____ 2 3 4 B ____ 2 4 6 C A 1 2 3 D B 3 6 9 E C, D 7 8 9 F D 4 7 10 G E 3 4 5 H E, F…If the duration of each activity is known with certainty, then the critical path method can be used to determine the length of time required to complete a project. Select one: a. True b. FalseYou are provided with the following information for a project, with activity durations given in weeks: Activity Immediate Optimistic Most Likely Pessimistic Predecessor Time (a) Time (m) Time (b) A ____ 2 3 4 B ____ 2 4 6 C A 1 2 3 D B 3 6 9 E C, D 7 8 9 F D 4 7 10 G E 3 4 5 H E, F…
- PERT analysis computes the variance of the total projectcompletion Lime as:a) the sum of the variances of all activities in the project.b) the sum of the variances of all activities on the critical path.c) the sum of the variances of all activities not on the criticalpath.d) the variance of the final activity of the project.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.Consider again the project with the activity network shown in Figure 19.14.Activity A1 takes 4 days; A2, 2 days; A3, 10 days; A4, 4 days; A5, 2 days; A6, 3 days; A7,5 days; and A8, 2 days. Compute the earliest completion time of the project.Answer: 26 days.We start the project with A1 because it has no predecessor activity. A1 will take 4 days, sothe ECT for A1 is 4. Once A1 is complete, we can start on A2. A2 thus has an EST of 4. A2takes 2 days and hence has an ECT of 6.Following the completion of A2, we can initiate A3, A4, and A5. These activities thus canall have an EST of 6. We continue this process as shown in Table 19.13 and find that theearliest completion time is 26 days.
