Project Resources and Cost Assignment

Chapter 8

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 Chapter 8 Scheduling Resources and Costs 281Carpenter 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?

LegendSLResourceScheduleCCEC2-EC3. Compute the early, late, and slack times for the activities in the network that follows, assuming a time-constrained network. Which activities are critical? What is the time-constrained project duration? Note: Recall, in the schedule resource load chart the time-constrained scheduling interval (ES through LF) has been shaded. Any resource scheduled beyond the shaded area will delay the project. Assume you have only three resources and you are using a computer that uses software that schedules projects by the parallel method and following heuristics. Schedule only one period at a time!

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?

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 Chapter 8 Scheduling Resources and Costs 285Brooker 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?220112311104445144233275697297003300033011112IDDURLSSLLFESEFLegendSLResource257347300DURESLFSLSchedule the resource load chart with ES and Slack updates012345678910111213IDRES154123123303273447052000237906Resources scheduled2Resources available2222222222221111227. *You are one of three carpenters assigned to complete a short construction project. Right before the start of the project, one of your fellow carpenters was hospitalized and will not be available to work on the project. Develop a resource-constrained schedule in the loading chart that follows to see how long the project will take with only 2 carpenters.
