Exercise question I Reducing Project duration Dr. Deaton Fendcr, a Dotod goologist, bes discovered a site that she believes may hold a large deposit of natural gas. To test for the possible presence of natural guns, she proposes to drill a test hole, set off a small explosive change, and use the resulting seismic pattern to indicate the likely presence or absence of natural pas. The process of testing a likely site has been divided into five tasks that are indicated in the following AON precedence network Taska 8 days Task D 4 days Task E 5 days START Task C 12 days END Task B 10 days Dr. Ferder has estimated the times and costs of each task assuming normal conditions, its well as the times and costs of each task assuring a crashed or reduced condition. This information is indicated in the lble that follows: Normal Crash Task Duration Cost Duration Cost Slope 0 6 START Task A Task B Task C Task D Task E END 0 8 10 12 4 5 0 $ 10D $ 70 $260 $ 80 $ 100 $ 200 $ 170 $ 500 $ 80 $ 175 $ 50 $ 20 $ 60 5 8 8 4 2 0 $ 25 Under normal conditions. Dr. Fender estimates that the test procedure would take twenty-two days (the length of the critical path mie nu comitions) and cust $610 in direct acists. a) Criven the impulance of new sources of natural gas, she wants to consider pissible shorter sccbarios: thus, she would like you to reduce the project one day at a time and calculatc the minimum direct cost associated with cach day. Summarize your findings in a table. What is the shortest possible time needed for this project? h) If overhead (indirect charges are $501 per clay, what wuld be the project duration that minimizes the sum of direct and indirect charyas? c) Assume that an incentive (bonus) is now offered if the project is completed in ninctoen days. Assuming that the overhead (indirect) charges in pat remain in effect, bow large would the incentive have to be to make it firancially attractive for Di Fender to complete this project in ninete days?
