Problem 12-09 (Algorithmic) A project has four activities (A, B, C, and D) that must be performed sequentially. The probability distributions for the time required to complete each of the activities are as follows: Activity Time Activity (weeks) A 8 9 10 11 B 8 10 H 12 с 9 11 13 15 17 12 14 Probability 0.34 0.34 0.27 0.05 0.17 0.51 0.32 0.05 0.26 0.35 0.23 0.11 0.68 0.32
a. Provide the base-case, worst-case, and best-case calculations for the time to complete the project. Activity Base case A B C D Total B с D Total weeks weeks 0.2186 0.4655 weeks 0.8641 0.9039 weeks weeks Worst case Activity Random Number Completion Time A weeks weeks weeks weeks weeks weeks b. Use the random numbers 0.2186, 0.4655, 0.8641 and 0.9039 to simulate the completion time of the project in weeks. weeks weeks weeks Best case weeks weeks weeks weeks weeks weeks c. Discuss how simulation could be used to estimate the probability that the project can be completed in weeks or less. Simulation provides a distribution of project completion times. Th✔ mean percentage of times weeks and under can be used to estimate the probability that the project will be completed within w
