Dave Fletcher was able to determine the activity times for constructing his laser scanning machine. Fletcher would like to determine ES, EF, LS, LF, and slack for each activity. The total project completion time and the critical path should also be determined. Here are the activity times: Time from hellite De hon akt

Relevant information for a project consisting of activities A, B, ..., K is provided in the table below and the project network is provided. Activity Time in Weeks A 8 B 4 C 3 D 4 E 2 F 2 G 4 H 4 I 3 The project network is: B DE What is the slack for activity C? E What is the earliest start for activity G? What is the critical path? What is the earliest finish for activity B? Immediate Predessors ΝΑ A A B What is the project completion time? B с E, F D G, H (G Enter the letters of the activities on the path in capitals (e.g. ABCDEFG).

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…

Canesta Company is working on a project with the following network:  a) Determine the earliest and latest activity times and slack for each activity. b) Determine the duration of the project and the critical path.

Draw the activity-on-node (AON) project network associated with the following activities for Carl Betterton's construction project. How long should it take Carl and his team to complete this project? What are the critical path activities?

Calculate, ES, EF, LS and LF for each activity, and highlight the critical path indicating the length of this project.

Suppose that the project team has arrived at the following time estimates for activity B (Select site and survey) of the St. John’s Hospital project: a = 7 weeks, m = 8 weeks, and b = 15 weeks a. Calculate the expected time and variance for activity B. b. Calculate the expected time and variance for the other activities in the project.

The following table provides the information necessary to construct a project network diagram and project crash data: Crash the project until no more crash can be performed How much it would cost The new critical path(s) Activity Immediate predecessor Activity Time (weeks) Activity Cost ($) Normal Crash Normal Crash A -- 16 8 2000 4400 B -- 14 9 1000 1800 C A 8 6 500 700 D A 5 4 600 1300 E B 4 2 1500 3000 F B 6 4 800 1600 G C 10 7 3000 4500 H D, E 15 10 5000 8000 End F, G, H
