(total 14 points) Given the following project information (all time are in weeks). Crash Normal Normal Activity Predecessor(s) time cost Crash time Per week crash cost cost A 5 300 300 0 B A 8 250 400 50 A 2 100 100 0 D A 6 300 3 600 100 7 00 N N N 01 07 E B,C 3 150 300 150 F C,D 4 275 325 25 G E,F 9 700 900 200 H D 12 990 1170 90 Project total normal costs $3,065 The corresponding project network is as follows: B E 8 3 G A 9 5 2 Legend 4 ID D H Dur 6 12 The project duration and total direct costs for an all-normal level of project activity are 25 weeks and 3,065$, respectively. a) (10 points) What activities should be crashed assuming the management desires a deadline of 22 weeks and What is the project total costs? Apply the cost-time trade-off with a method of your choice (tabular or network) and provide your summary solution in the table below (there is no need to submit your draft work). Number total of weeks the activity will be crashed (indicate 0 if no crashing occurs for an activity) ACTIVITY Total direct crashing cost of the activity (indicate 0 if no crashing occurs) A B E F G H The project total direct crashing costs (including the normal costs) - $ (with no comma nor space) b) (4 points) Assume the following additional information. The indirect costs for each production duration are $750 (for 25-weeks project duration), $600 (for 24- weeks project duration), $400 (for 23-weeks project duration), and $300 (for 22-weeks project duration). Based on your analysis (as per question (a) above), what project duration would you recommend to the management when considering now both the total direct and indirect costs. The recommended project duration after considering crashing decisions is weeks. This will cost the firm a total cost of $ considering both direct costs (including the normal costs) and indirect costs
