1. 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, Electrical Engineers (EE), and re-source, Mechanical Engineers (ME). Assume only one of each resource exists. 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? Could something like this happen in real projects? (Gray & Larson, 2014, p. 280).
2. You have prepared the following schedule for a project in which the key resource is a backhoe. This schedule is contingent on having three 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 possible to complete the project in 11 months with only two backhoes.
Be sure to record the order in which you schedule the activities using scheduling heuristics. Activities 5 and 6 require two backhoes, while activities 1, 2, 3, and 4 require one backhoe. No splitting of activities is possible. Can you say yes to Brooker's request? (Gray & Larson, 2014, p. 284-285).
