You acknowledge that the activity times in Table 1 are actually still very uncertain. Table 2 shows the optimistic, most likely, and pessimistic estimates for the duration of each activity. Question 3: What is the probability of completing the project in 30 weeks or less? 8% 25% 18% O 2.5% PART 3: Figure 1 shows a network diagram of a project indicating the normal time duration of each activity. In this part you are asked to provide a crashing plan to accelerate the duration of this project. Table 3 shows: . . the expected duration for each activity, the crash time the absolute minimum time in which each activity could be accomplished), and the additional cost per day of obtaining that crash time. Provide a crashing plan to reduce the project duration from 36 days to 33 days in the most cost-efficient way possible. Hint: Remember that the project duration is reduced one day at a time by selecting the activity on the critical path that requires the lowest additional cost Question 4: Which activities will you crash? In which order? Provide a crashing plan to reduce the project duration from 36 days to 33 days in the most cost-efficient way possible.
