Scheduling And Cost Problems

Exercise #2

Given the network plan that follows, compute the early, late, and slack times. What is the project duration? Using any approach you wish (e.g., trial and error), develop a loading chart for resources Carpenters (C) and Electricians (E). Assume only one Carpenter is available and two Electricians are available. Given your resource schedule, compute the early, late, and slack times for your project. Which activities are now critical? What is the project duration now?

 

 

Exercise #5

Develop a resource schedule in the loading chart that follows. Use the parallel method and heuristics given. Be sure to update each period as the computer would do. Note: activities 2, 3, 5, and 6 use two of the resource skills. Three of the resource skills are available. How has slack changed for each activity? Has the risk of being late changed? How?

 

Exercise #6

You have prepared the following schedule for a project in which the key resource is a backhoe(s). This schedule is contingent on having 3 backhoes. You receive a call from your partner, Brooker, who desperately needs one of your backhoes. You tell Brooker you would be willing to let him have the backhoe if you are still able to complete your project in 11 months. Develop a resource schedule in the loading chart that follows to see if it is pos-sible to complete the project in 11 months with only 2 backhoes. Be sure to record the order in which you schedule the activities using scheduling heuristics. Activities 5 and 6 require 2 backhoes, while activities 1, 2, 3, and 4 require 1 backhoe. No splitting of activities is possible. Can you say yes to Brooker’s request?
