PART B: Please determine the total cost for this project's schedule.

The work has been provided. Thanks!

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 center must rent other space at a nearby 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. Normal Time Normal Cost ($) Crash Time Idays) Crash Cost (S) Immediate Activity START (days) Predecessor(s) START START Omow> 440 280 290 320 AC AC 30 440 FINISH GH a. Using the normal times for each activity, what is the earliest date you can complete the project? The corresponding project duration using the normal times is 26 days. (Enter your response as an intoger.) b. Suppose the variable overhead costs are $40 per day for your project. Also, suppose that the center must pay $50 per day for a temporary room on day 17 or beyond. Find the minimum-cost project schedule. Fill in the table below to show the proper schedule time for each activity after crashing) for completing the project at minimum cost. (Enter your responses as integers.) Activity Time (days) Activity Time (days) CD W LOI Determine the total cost for this project's schedule. Total cost = $_-(Enter your response as an integer.) Answer: activity required time cost time available for crashing= normal duration crashed duration cost of crashing per period= (crashing cost-normal cost/periods available for crashing normal duration crashed duration normal cost crashing cost $50 $440 $130 $40 $280 3 $80 $70 $290 2 3 $110 $100 $20 $320 $30 $30 $440 $80 $50 $60 3 1 $120 $40 2 8 $90 11 $150 3 $30 Paths ADG Duration 21 AEH BCDG BFH Steps for crashing a project select the critical path and find the process with the least cost of crashing per week If there are multiple critical paths, look for processes that are common, common processes may have low effective cost as common process crashes more than 1 path at once you can only crash an activity depending on the time available for crashing. If an activity is only crashed that much time, choose another activity add the cost of crashing later As we are told, The daily overhead cost is $40 and Rent for temporary room is $50. Total = $40 + $50 = $90 per day This means, our crashing cost should be less than $90 per day.
