The city of Bloomington is about to build a new watertreatment plant. Once the plant is designed (D), we canselect the site (S), the building contractor (C), and theoperating personnel (P). Once the site is selected, we canerect the building (B). We can order the water treatmentmachine (W) and prepare the operations manual (M) onlyafter the contractor is selected. We can begin training (T)the operators when both the operations manual and operatingpersonnel selection are completed. When the treatment plantand the building are finished, we can install the treatmentmachine (I). Once the treatment machine is installed andoperators are trained, we can obtain an operating license(L). The estimated mean and standard deviation of the time(in months) needed to complete each activity are given inTable 8. Use simulation to estimate the probability that theproject will be completed in (a) under 50 days and (b) morethan 55 days. Also estimate the probabilities that B, I, andT are critical activities.
