CHA90 Spring 2120 Management TYPE: A 2. Ch. 3. Project Management Jacksonville Bike Shop is behind on a custom bike and needs to crash 1 day of time from the 6-step project. Given the project table below answer the following questions. Suppose this shop calls the customer and asks for a project extension, reducing the amount of time she/he needs to crash. (Note: The project can be speeded up (or "crashed") by spending more money on each activity For example, activity A currently takes 10 days, but can be reduced to cither 9 days or 8 days at additional costs. (20 pts) Activity Immediate Predecessors Normal Time (days) Normal Crash Time Cost (days) Crash Cost 30 70 120 150 160 5 100 40 508 50 75 95 F (a) Draw a project network diagram, including activity durations under the normal business conditions. (Please show all the activities from the starting point to the end.) You may use either AON (Activity On Node) method or AOA (Activity On Arrow). (2 pts) (Hint: Please use the normal time for the duration of each activity.) b) What is the Critical Path in the network? (2 pts) (Hint: Please use the normal time for the duration of each activity.) (c) What is the Project Completion Time? (2 pts) (Hint: Please use the normal time for the duration of each activity.) CHAM Spring 2000 TYPE: A 2. (Continued) (d) What is the maximum possible reduction time (in days) for the activity CP (2 pts) (e) Challenging Question based on Online Class Discussion-Slack Time What is the slack time in days) associated with any and all non critical paths through the project? If activity D were delayed by TWO time units (days), what would happen to the entire project duration Please specify whether the cute pro will be delayed or not. (Please show all your work. You may compute the slack time using ES, EF, LS, and LF in your project network diagram) (6 pts) (t) Let's assume that your client wants you to finish your project one day earlier. [Part 1] Which activities should be crashed to reduce the duration of the project and Part 2 how much is the minimum additional cost, if the objective is to minimize the total crashing costs, while meeting the deadline of 30 days (by reducing the duration of the project by one day)? (Please show all your work.) (6 pts)
