Three activities are candidates for crashing on a project network for a large computer installation (all are, of course, critical). Activity details are in the following table: Activity A B C Normal Time Crash Time Normal (days) (days) Cost 7 6 4 11 2 9 $5,000 $1,400 $4,000 Total Cost with Immediate Crashing Predecessor(s) $5,600 $3,300 $6,400 a) Activity that should be crashed first to reduce the project duration by 1 day is A b) Activity that should be crashed next to reduce the project duration by one additional day is A B A B C ect: 0
A project consists of five activities listed below. The project network is shown for the activities. The critical path is B-C-E and the expected completion time is 8. Optimistic Most Probable Pessimistic Activity Time (hr) Time (hr) Time (hr) A Floor sanding 3 4 5 B Paint mixing 0.5 1 1.5 C Ceiling painting 1 5.5 7 D Wall painting 1 2 9 E Floor buffing 1 2 3 What is the probability that the project can be completed within 9 hr.?
Activity A can start as soon as the project starts, and set the earliest start time for activity an equal to 0. With an expected activity time of 5 weeks. Using this information what is the earliest finish time for activity A?
Below is a network diagram that represents a university revamp project. The project manager analyzes this project using the critical path (CP) method. Activity durations are indicated on the network
Shrink the occurrence time of the following project and find: a) The critical path and the expected project completion time. b) Find the optimal duration and optimal cost. Normal Crash Activities Time Cost Time Cost 1-2 100 1-3 150 2-4 50 2-5 100 3-4 100 4-5 80. 843324 722213 200 230 90 150 200 100
A project has 7 activities P, Q, R, S, T, U, and V. Three time estimates (optimistic, most-likely, pessimistic) are used for each activity. Write down your answers to all parts of the question in the box given below. Give your answer to 3 decimal places. (Note (a) has of 2 parts and (b) has of 3 parts) For activity Q, these time estimates are as follows: optimistic time = 9, most-likely time = 14, pessimistic time = 20. Write down the average activity time for Q the variance of activity time for Q. The critical path of this project has a mean project time of 44 days and a standard deviation of 5 days. Assume project completion time is normally distributed. Find the probability that the project will be completed in 47 days. Find the probability that the project will take more than 40 days. We want to set a deadline for this project completion. If the probability of meeting this set deadline is 0.88, what will be the deadline for this project.
A project consists of seven activities, lettered A through F below. For each activity, the estimated normal time in number of weeks, crash time, normal cost, crash cost, and its preceding activity are given.

Suppose you are the project manager for the following project: First, draw a network diagram for the project. Determine the critical path and slack times for all of the tasks. This completes your plan for the project schedule. During project execution, you become aware of the need to change the duration of Task 4 to five days. Meanwhile, Task 3 has been finished one day early, so it only took one day to do. What, if any, effects do these changes have on your project? What would have happened if you had not been monitoring the status of the project?
Use the Program Evaluation and Review Technique to represent the project in an activity network. In conjunction with the Critical Path Method, use the activity network to find the shortest time possible to complete the project, to identify the critical jobs in the project, and to determine the earliest and latest that each activity can start and finish without making the project completion longer.a=1, b=1, c=6, d=5, e=2, f=5; andab=1x1=1, bc=1x6=6, cd=6x5=30, de=5x2=10, ef=2x5=10, af=1x5=5.
The Virginia Department of Transportation is undertaking a construction project to widen a large section of interstate highway near Wahington, DC. The project includes the construction of a number of new bridges, interchanges and overpasses. The first step in the process is to appoint a project manager and develop a project team, whose members will be departmental employees and private consultants and operatives. The team for a project of this size also requires a large support staff with a variety of technical skills. Once the team is selected and the staff is in place, the next task is to select a primary contractor to manage and oversee the construction. The following activities are standard for the planning and scheduling of this process: Activity Activity description Time predecessor estimates (weeks) Activity a | b Select project management 2 2 a b Develop team recruitment process 3 a. Implement team recruitment process by 3. 6. Staff needs assessment 3 Staff recruitment…
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.
