Hello,

Can someone help me with this problem?

Problem 2: For the following data for critical path of a network (the listed activities are all on the critical path in a linear configuration, that is, the critical path is 1-2-3-6-15-17-18-19-20):

Activity 1 - Drain off

80% Estimate - 8

Max Duration - 12

Activity 2 - Chimney

80% Estimate - 8

Max Duration - 12

Activity 3- Drill out

80% Estimate - 6

Max Duration - 23

Activity 6-Lower Brick

80% Estimate - 24

Max Duration - 35

Activity 15-Recover

80% Estimate - 27

Max Duration - 35

Activity 17-Dismantle

80% Estimate - 12

Max Duration - 16

Activity 18-Joinery

80% Estimate - 14

Max Duration - 18

Activity 19-Plaster

80% Estimate - 20

Max Duration - 25

Activity 20-Finish

80% Estimate - 2

Duration 3

I. Please determine the time buffer for 90% confidence level using Unified Scheduling Method (USM).

II. What is the recommended duration of the project based on the above information?

III. For comparison, now determine the project duration with 90% confidence level using Monte Carlo Simulation in @Risk using only the data for critical path and Discrete Distribution representation of the data provided above. Please include the project duration distribution graph in the PDF file.

IV. For another comparison, now determine the project duration with 90% confidence level using PERT analysis using only the critical path data.

V. Comment in a few sentences each on the differences and the reasons for differences in (a) USM and Monte Carlo Simulation, and (b) USM and PERT analysis, for determining the project duration.
