Given the following activity network: Three nodes - A1, A2, A3; two paths - A1, A2 and A1, A3. Activity A1 takes 5 weeks, A2 takes 7 weeks, and A3 takes 4 weeks with a 50% probability and 10 weeks with a 50% probability. What is the project completion time under the worst-case scenario, that is, A3 is late and takes 10 weeks? A. 15 B. 10 C. 12 D. 9

Development of Version 2.0 of a particular accounting software product is being considered by Jose Noguera's technology firm in Baton Rouge. The activities necessary for the completion of this project are listed in the following table: Activity A BCDEFG Normal Time Crash Time Normal (weeks) Cost $2,100 Total Cost with Immediate Crashing Predecessor(s) 4 $2,800 $2,200 $2,900 $750 $750 $2,500 $2,820 $1,000 $1,300 $3,200 $4,700 $1,400 $1,900 2 3 8 6 3 4 (weeks) 3 1 34 4 322 a) Based on the given information regarding the activities for the project, the project length = b) The total cost required for completing this project on normal time = $ weeks. c) For reducing the duration of the project by one week, the activity that should be crashed first is activity The cost of the project based on the first activity selected for crashing will increase by $ d) The maximum weeks by which the project can be reduced by crashing = Total cost of crashing the project to minimum (or maximum weeks…

Swimming Pool Installation: You are the project manager working for Mack's Pool Co. Your project consists of installing a new swimming pool at the local country club before Memorial Day weekend (pool opening weekend). You would like to find the minimum cost schedule for your project. There is a $9,000 per week penalty for each week the project is delayed beyond week 9. In addition, your project team determined that indirect costs are $15,000 per week. ACTIVITY Immediate Predecessor (s) NORMAL TIME (NT) CRASH TIME (CT) Normal Cost (NC) Crash Cost (CC) A -- 2 1 7,000 10,000 B -- 2 2 3,000 3,000 C A 3 1 12,000 40,000 D B 3 2 12,000 28,000 E C 1 1 8,000 8,000 F D, E 5 3 5,000 15,000 G E 3 2 9,000 18,000 Before crashing, the project duration is _________ week(s).

What precisely does the critical route approach achieve, however, and why is it such a vital part of project scheduling?

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.?

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

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.
