Question
The following is a table of activities associated with a project at Ratay Ishtaq's software firm in Chicago, their durations, what activities each must precede and the crash cost to reduce duration per week: Suppose that Ratay is only given 7 weeks (instead or 10) 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. What is the total crashing cost? $ (Enter your response as a whole number.) Enter your answer in each of the answer boxes.Explanation / Answer
Assuming ach activity can be crashed to 0 weeks duration and the activities should be rashed in such a way that the crash cost is minimum, then A can be crashed by 0 week (i.e. A should not be crashed), B by 2 weeks, C by 3 weeks, E by 1 week and F by 0 weeks (i.e. F should not be crashed). (Ans).
Thus, total crashing cost = $(120 * 2) + $(200 * 3) + $(150 * 1) = $990. (Ans)
