The following is a table of activities associated with a project at Rafay Ishfaq's software firm in Chicago, their durations, what activities each must precede and the crash cost to reduce duration per week: Duration Crash Cost/Week Activity (weeks) Precedes В. С A (start) B $370 $110 $220 $150 4 F E 1 F F (end) $420 Suppose that Rafay is only given 6 weeks (instead of 9) to complete the project. By how many weeks should each activity be crashed in order to meet the deadline? Assume that you can crash an activity down to 0 weeks duration. Each Activity Should be Reduced Activity BY (weeks) A week(s)

Project Management

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:

Activity ADEIF А H 4. A construction company planned for a new project and represented the tasks of the project as a list of immediate predecessors, estimated duration (best, most likely, worst) as follows: Estimated duration (best-most likely-worst) in weeks G B I J K с M N O End immediate predecessors A D E A F LL B J с M N H,G,K,O 2-4-6 6-8-10 7-9-12 Earliest Start 2-3-5 3-4-8 5-7-9 2-2-3 2-3-6 3-4-5 4-5-8 5-8-12 1-1-1 6-7-11 8-9-13 a. Draw a network diagram (activity on node), compute the earliest start and finish times of each task using most likely values. b. Compute the latest start and finish times of each task fill the rest of the values in a table format as follows: Activity Earliest Finish Latest Start Latest Finish Slack Is critical? C. If the project is finished within 27 weeks of its start, the project manager will receive a bonus of 500$. Find the probability of getting the bonus.
