5. For the following simple seven-activity project, develop a precedence network, calculate all relevant characteristics of each activity (ES, EF, LS, LF, TF), and calculate the project duration. Then draw a time-scaled network and under it a labor resource histogram for the ES. Do the same for the LS. In both cases, use the maximum allowable number of workers. Make adjustments to the noncritical activities, within the constraints of the ES and LF and the maximum and minimum workers allowed to provide what you feel is the best labor distribution. Please use Table B (Table B.pdf) Lastly, Explain in detail what do you feel is the biggest problem with the ES and LS configurations, and how has this been alleviated with your solution?
