You may need to use the appropriate technology to answer this question. Consider the PERT/CPM network with estimated times in weeks shown in the following figure. The project is scheduled to begin on May 1. Start A B с D E F G H 1.0 The three-time estimate approach was used to calculate the expected times and the following table gives the variance for each activity.

You have determined the following for a given project: Expected completion time of the project = 26 weeks Standard deviation of project completion time = 8 What is the probability of completing the project in more than 32 weeks? answer as a decimal and take it to four places.
In reference to the attached image: Determine the best way to crash the project to complete it in 35 weeks with revised activity slack times, critical path(s), and total project costs. Provide reasoning as to how all crashing decisions were made.
In reference to the attached image: Draw the project network, and determine the normal time to complete the project, activity slack times, the critical path(s), and total project costs (i.e., baseline your project), using the Critical Path Method.
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: Activity Time (weeks) Immediate Predecessor(s) Activity Time (weeks) Immediate Predecessor(s) A E 4 В В 8 F 6 В 4 A G 10 С, Е 3 A H 7 D,F Dave's earliest start (ES) and earliest finish (EF) are:
Draw the Network Diagram based off the table of dependencies Draw the critical path using the following activity notation.
