Your hospital has applied for certification as a level 1 stroke center. It is critical that the following project is completed in 18 weeks, before the next Joint Commission survey. Project activity times are listed in the table attached as an image.  Determine the minimum cost-schedule for this project to be completed in 18 weeks. Assume a linear relationship between crash cost and crash time. For example, crash cost per week for activity A can be calculated as: ($650 - $200)/(4-2) =  $225. 2. What is the difference in total project costs between the earliest completion time of the project using normal times and the minimum cost-schedule you found in part 1?

The Advanced Tech Company has a project to design an integrated information data base for a major bank. Data for the project are given in the following table. Indirect project costs amount to ​$250 per day. The company will incur a ​$200 per day penalty for each day the project lasts beyond day 12.                                                                                                                                                                Activity Normal Time​ (days) Normal Cost​ ($) Crash Time​ (days) Crash Cost ​($) Immediate​ Predecessor(s) A 5 800 4 1,000 − B 5 1,100 2 2,900 − C 2 600 1 900 ​A, B D 3 1,200 2 2,000 B E 3 1,500 2 1,700 ​C, D F 2 1,300 1 1,400 E G 3 900 3 900 E H 5 500 2 800 G a.

You are in charge of a project at the local community center. The center needs to remodel one ofthe rooms in time for the start of a new program. Delays in the project mean that the center mustrent other space at a nearby church at additional cost. Time and cost data for your project arecontained in below table. Your interest is in minimizing the cost of the project to the communitycenter.Using the normal times for each activity, what is the earliest date you can complete the project?Suppose the variable overhead costs are $50 per day for your project. Also, suppose that thecenter must pay $40 per day for a temporary room on day 15 or beyond. Find the minimum-costproject schedule using below format.The AON diagram for the community center project is below. Crash 4 times and find total cost.
