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 callsthe customer and asks for a project extension, reducing the amount of time he needs to crash. Calculateboth the maximum time-savings available on a $25 crash budget and the cost to crash four hours ofsavings.

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?

You are in charge of a project at the local community center. The center needs to remodel one of the rooms in time for the start of a new program. Delays in the project mean that the center must rent other space at a nearby church at additional cost. Time and cost data for your project are contained in 7.10. Your interest is in minimizing the cost of theproject to the community center.a. Using the normal times for each activity, what is the earliest date you can complete the project?b. Suppose the variable overhead costs are $50 per day for your project. Also, suppose that the center must pay $40 per day for a temporary room on day 15 or beyond. Find the minimum-cost project schedule.
