Problem 12 Assigned Media Question Help The table below contains information about an environmental clean-up project in the township of Hiles. Shorten the project three weeks by finding the minimum-cost schedule. Assume that project indirect costs and penalty costs are negligible. Identify activities to crash while minimizing the additional crash costs.

B 460 280 20 50 5 5 70 140 P You are in charge of a project at the local community center. The center needs to remodel one of the rooms in time for the start of a new program. Delays in the project mean that the anter must rent other space at a neart church at additional cost. Time and cost data for your project are contained in the table below. Your interest is in minimizing the cost of the project to the community Center Activity Normal Time Normal Cost (5) Crash Time (days) Immediate Crash Cost (5) (day) START 0 0 0 0 0 170 START B 2 250 START C 70 2 B D AC E AC F 80 B 180 G D H EF FINISH 0 GH Using the normal time for each activity, what is the earliest date you can complete the project? The corresponding project duration using the normal times is 22 days. (Enter your response as an integer.) b. Suppose the variable overhead costs me $30 per day for your project. Also, suppose that the center must pay 570 per day for a temporary room on day 16 or beyond. Find the minimum-cost project schedule Fil (. Fill in the table below to show the proper schedule time for each activity after crashing) for completing the project at minimum cost.

Your company is responsible for the installation project. Indirect costs are $12,000 per week, and a penalty cost of $10,000 per week will be incurred by your company for every week the project is delayed beyond week 14.
