Question

project has four activities (A, B, C, and D) that must be completed sequentially in order to complete the project. The probability distribution for the time required to complete each of the activities is shown below.

                                    Activity Time

            Activity        (weeks)       Probability

            A                    5                     .25

                                    6                     .30

                                    7                     .30

                                    8                     .15

            B                    3                     .20

                                    5                     .55

                                    7                     .25

            C                     10                  .10

                                    12                  .25

                                    14                  .40

                                    16                  .20

                                    18                  .05

            D                    8                     .60

                                    10                  .40

            a. Use a random number procedure to simulate the completion time for each activity. Sum the activity times to establish a completion time for the entire project.

            b. Use the simulation procedure developed in part a to simulate 20 completions of this project. Show the distribution of completion times and estimate the probability that the project can be completed in 35 weeks or less.
