The project manager of a task force planning the construction of a domed stadium had hopedto be able to complete construction prior to the start of the next college football season. Afterreviewing construction time estimates, it now appears that a certain amount of crashing will beneeded to ensure project completion before the season opener. Given the following time and costestimates, determine a minimum-cost crashing schedule that will shave five weeks off the projectlength.

You have collected the data for a Time-Cost CPM Scheduling model analysis. The time is in days and the project "direct costs" are given below. Immediate Normal Crash Normal Crash Activity Predecessor Time Time Cost (Direct) Cost (Direct) A None 3 2 $300 $408 B A 3 3 $100 $100 C A 1 1 $200 $200 D B and C 3 2 $400 $550 E D 2 1 $500 $900 F E 3 3 $200 $200 G F 2 2 $200 $200 The indirect costs for the project are determined on a daily duration basis. If the project lasts 16 days the total indirect costs are $408, 15 days they will be $350, 14 days they will be $200, and 13 days they will be $100. If you crash this project by one day what is the total (i.e., direct and indirect) project cost?
Assume that the activities in Problem 3.11 have the following costs to shorten: A, $300/week; B, $100/week; C, $200/ week; E, $100/week; and F, $400/week. Assume also that you can crash an activity down to 0 weeks in duration and that every week you can shorten the project is worth $250 to you. What activities would you crash? What is the total crashing cost? Note: The attached photos is the activities in problem 3.11.
I also know answer is d, but please explain each and every option why other option are incorrect too. Which of the following statements regarding PERT analysis is true? Each activity has two estimates of its duration. Project variance is the sum of all activity variances. Project standard deviation is the sum of all critical activity standard deviations. Only critical activities contribute to the project variance. none of these is true.

Hi, I need help answering the last question. Rob Smith is managing a small project at Boston University. He is under pressure to shorten the overall duration of the project by 4 weeks and he wants to do so at the lowest cost possible. In order to meet this objective a number of activities must be crashed. Activity Normal Time (weeks) Crashed Time (weeks) Normal Cost Crashed Cost Predecessor(s) A 5 3 $800 $1,200 - B 6 5 $300 $450 - C 6 5 $550 $775 - D 3 2 $750 $950 A E 6 3 $1,350 $2,250 C F 5 3 $675 $875 B What is the total cost of crashing the project 4 weeks (just the additional cost, not total project cost)? (Display your answer to two decimal places.)
(i) Project's standard deviation is the square root of the variance. Write a formula in cell F48 to compute the project's standard deviation.(j)The earliest finish time for the last activity is the Project's duration. Write a formula in cell F50 to compute the project's duration. (Hint: You have to only refer to the cell range)We would like to use the variance information to compute the probability that the entire project will be complete in 35 days. Screenshot attached thank you!! z
9. A project has the following activities, with specified precedents, expected durations (in days), and crash cost/day. Each activity can be crashed to a minimum duration of 1 day. (This is the same network as a previous problem.) What is the minimum total cost to shorten the project by 2 days? Round your answers to 2 decimals. Activity Precedent Duration Crash cost/day A - 3 $350 B A 3.8 $250 C A 6 $400 D B 6 $150 E B 4.1 $200 F C 4 $275 G D 6.2 $500 H E 8 $300 Answer:
