The network diagram of a project with four activities is presented below. Start A B C D The estimated optimistic, most likely, and pessimistic times of each task are given in the table below. The expected time and variance of acitivities A are also given in the table. The expected time and variance of activity C and D are irrelevant in this problem. So they can be ignored. optimistic 14 4 5 5 most likely B 18 10 7 10 End pessimistic 23 18 13 12 Expected time 18.167 XX mm variance 81/36 [Three decimal places for all answers) (1) What is the expected task time of activity B? (2) What is the variance of the task time for activity B (3) What is the expected length of path A-B? (2) What is the standard deviation of the length of path A-B? yy 22

Consider a project that has been modeled as in Table 1 Draw the PERT/CPM network for this project and determine the project’s expected completion time µP and its critical path. Suppose the standard deviations of the activity durations are σA = 2, σB = 1, σC = 0, σD = 2, σE = 3, and σF = 0. Then please estimate the standard deviation of the overall project’s standard deviation σP . Suppose for the standard Normal random variable Z, we know P[−1 ≤ Z ≤ +1] ' 68%, P[−2 ≤ Z ≤ +2] ' 95%, and P[−3 ≤ Z ≤ +3] ' 99.7%. Then, approximately what time T is one for which there is only a less than 2.5% chance for the completion time to beat (be shorter than)?

The project duration in a network model can be determined by the largest value of which variable associated with the critical path?
