Homework Answers
A) The duration represented by the critical path corresponds to the project’s minimum duration. Correct option
E) Both B and C. Correct option

Question 18 What are the two principles when crashing a project? Focus on the critical path, select the least expensive alternative. Reduce the cost, reduce the duration. Reduce the duration, increase the cost. Reduce the use of resources, reduce the cost 4 points Question 19 The formula for computing the cost/time slope for each activity that can be crashed is . (Crash cost + Normal cost) / (Crash time + Normal time) (Crash cost - Normal cost) / (Crash time...

Question 16 4 points Save Answe The following provides information about a project, including a list of activities and precedence relationships, activity durations (normal and "crash" times), direct activity costs (normal and "crash"), indirect costs for the project, as well as calculated crash costs/day and the maximum amount that each activity can be shortened (crashed) by. There are no penalty costs for this project. Total project cost (using normal times), a network diagram, and the four paths and durations have...

Development of a new deluxe version of a particular toy is being considered by T-O-Y Inc. The activities necessary for the completion of this project along with the relevant information for each activity are listed in the following table. The Total Crash Time represents the time for that activity after it has been crashed the maximum crash time allowed for that activity. For example, we can reduce the time for Activity A by one week to 3 weeks after crashing...
