Since no indirect cost nor penalty cost information is offered, please consider the schedule and crash cost issues only.
1. Using Table of Crashing Decision, what is the earliest completion time of this project if normal times are used for all activities?
A. fewer than 13 weeks; B. 13 weeks; C. 14 weeks; D. more than 14 weeks
2. Using Table of Crashing Decision, what is the minimum time schedule for this project?
A. fewer than 8 weeks; B. 8 weeks; C. 9 weeks; D. more than 9 weeks
3. Using Table of Crashing Decision, if the project completion time has to be reduced by one week, which of the following activities should be crashed to minimize the extra cost of earlier completion?
A. Activity E; B. Activity J; C.Activity B; D. Activity H
4. Using Table of Crashing Decision, what is the difference in dollars, between the minimum-time schedule and the schedule created by crashing all activities to their limits? Assume that there are no indirect or penalty costs.
A. less than or equal to \$1,000; B. greater than \$1,000 but less than or equal to \$2,000; C. greater than \$2,000 but less than or equal to \$3,000; D. greater than \$3,000
5. Using Table of Crashing Decision, if the project’s normal earliest completion time is to be reduced by two weeks, what is the minimum additional cost that will be incurred in achieving this two-week reduction?
A. less than or equal to \$1,000; B. greater than \$1,000 but less than or equal to \$1,500; C. greater than \$1,500 but less than or equal to \$2,000; D. greater than \$2,000
