B A. A EEE Problem 1 (700 points) 12 months 7 months 18 months 4 months o 5 months 15 months In order to reduce the highway congestion and increase number of tourists, the local government plan to build a second highway to the Starry Bay, a world-famous tourism hotspot. The diagram describes the relations and duration between the regular construction activities for the highway. However, the sooner the highway construction finishes, the more taxes for the local government from the tourism. Experts estimates that the new highway will bring extra taxes of $1,000,000 per month for the local government from the tourism once it being used. So, the government want to speed up the highway construction. Following table show the crashing cost about each activity on the construction project. Crash Cost Crashing Activity per month availability A $400,000 6 B $200,000 2 $500,000 D $600,000 E $200,000 2 $800,000 2 NNANO if a. Determine all the paths, their expected durations and mark the critical paths. (100 points) Path # Activity of Path Path Duration b. Determine an optimal crashing plan and the total crashing cost. Please follow the column below to list all your crashing steps.
