1. Draw the network diagram for the project below.  2. What is the critical path and completion time for the project?  3. Determine the least expensive project cost if the duration is to be 10% shorter than normal project duration

Problem #2 Develop a network for the problem (below).   Determine the total project completion time and the critical path(s).   Activity Immediate Predecessors Time (Days) A - 3 B - 7 C A 4 D B 2 E C, D 5 F A 6 G E, F 3

A project network is shown below, with three time estimates (Optimistic Time-Most Likely Time-Pessimistic Time (in days)) for each activity in the network. a. Compute the expected time for each activity in the project network. b. Identify and list all possible paths in the project network. Compute the expected duration for each path in the project network. c. Identify the critical path(s) in the project network. What is the expected project completion time? d. Compute the variance of each activity on the critical path(s). e. Determine the project variance and project standard deviation. Use the PERT analysis results in 2(c) and 2(e) to answer questions (f), (g), (h), and (i) below:f. What is the probability that the project can be completed within 22 days of its start? g. What is the probability that the project can be completed within 16 days of its start? h. Determine the project deadline that gives this project a 78% chance of on-time completion. i. Determine the project deadline…
