13 Pirmin's Bike Shop is behind on a custom bike and needs to crash 8 hours of time from the 8-step project. Given the project table below calculate the crash cost for 8 hours of time-savings. Suppose Pirmin calls the customer and asks for a project extension, reducing the amount of time he needs to crash. Calculate  the cost to crash four hours of savings.   Activity Normal Duration (hours) Normal Cost ($) Crash Duration (hours) Crash Cost (S) Immediate Predecessors A 2 10 2 0 None B 3 15 2 23 A C 5 25 4 30 B D 3 20 1 24 C E 6 30 4 45 C F 1 5 1 0 C,E G 7 35 6 50 F H 10 50 7 80 D,G   Select one: a. $25 b. $58 c. $22.5 d. $28. e. $52

In the project considered below, activity crashing can take place over a wide range of reduction times. The cost per day of reduction is given: Activity Immediate Normal Time Cost/day Lower Time Predecessor (days) Limit A None 3 450 1 B None 4 300 2 A 3 200 D E 100 E A,B 500 1 F C.D 4 600 3 For example, activity C can be crashed from its normal time of 3 days down to as little as 1 day or anywhere in between; the cost per day to crash C is 200. a) Draw a network diagram for this project. What is the critical path? How long will the project take, if no crashing takes place? b) Determine the least cost way to crash activities in order to complete the project in 11 days; in 10 days; in 9 days; in 8 days. c) Suppose the due date for the project is 5 days and a penalty of $500 a day is assessed for each day late. What is the optimal number of days to crash the project? Why?

#3) Consider the following project, all durations are in days. Construct a precedence diagram, find the critical path and which tasks have slack and how much each has. Which tasks would you recommend crashing to reduce the project duration by six days assuming that it costs the same to crash each task and no task by be crashed to less than half its original duration and tasks A and N cannot be crashed at all?
