Student name: Problem 1 Task Predecesors Optimistic time Normal time (m) Pessimistic time (b) Variance 99% CL Variance 95% CL Variance 90% CL Solver solution (create the excel tables below this box) Given the project on the right. 1. a. Draw the network and find the critical path and total normal duration of the project. - ID T M U n u Note: If you draw the network by hand, copy the picture in this document after question 5 b. Calculate the time expected for each activity. F .G c. Calculate the variance at 99%,95% and 90% confidence levels for each H , IJ activity. 2. Calculate the probability of completing the project in 38 days with a 99%CL. 99% CL 90%CL Project Critical path 3. Calculte the probability of completing the project in 38 days with 90%CL. D = D = (H) Critical Path TE= (H) Critical Path TE= Project Norm. Duration 4. Calculate the probability of completing the project in 45 days with a 95% CL. Critical Path Variance = Critical Path Variance = STD (0) = STD (0) = 5. Calculate the probability of completing the project in 45 days with 90% CL P(T
