Chapter 7, Problem 11P
Consider a project to produce custom door moldings for GMC Acadia crossover vehicles, described in Table 7.4.
- If you start the project immediately, when will it be finished?
- You are interested iii completing your project as soon as possible. You have only one option. Suppose you could assign Employee A, currently assigned to activity G, to help Employee B, currently assigned to activity F. Each week that Employee A helps Employee B will result in activity G increasing its time by 1 week and activity F reducing its time by 1 week. How many weeks should Employee A work on activity F?

Consider a project to produce custom door moldings for GMC Acadia cross-over vehicles, described in Tablea. If you start the project immediately, when will it be finished?b. You are interested in completing your project as soon as possible. You have only one option. Suppose you could assign Employee A, currently assigned to activity G, to help Employee B, currently assigned to activity F. Each week that Employee A helps Employee B will result in activity G increasing its time by one week and activity F reducing its time by one week. How many weeks should Employee A work on activity F?
b) Assuming that each task is started as soon as possible, construct the corresponding resource loading diagram for the project. c) How would you rearrange the timing of project activities to reduce the fluctuation in resource demand? Assume that the overall project duration cannot be extended. Remember that the specified precedence relationships must be maintained. d) If there are only 20 workers available for the project, how would you assign workers to tasks to ensure that the project can be completed without violating the resource limit? In this case, the project duration may be extended if necessary (but without violating precedence relationships). e) Given the results from (c) and (d) above, what recommendations would you make to senior management regarding the staffing of this project, and why?
A project has 92 activities, but only 13 of them are analyzed here.
Activity P, 9 days, IP = not given
Activity W, 10 days, IP = not given
Activity S, 6 days, IP = not given
Activity A, 25 days, IP = P, W
Activity F, 24 days, IP W, S
Activity N, 21 days, IP S
Activity E, 28 days, IP = A
Activity M, 13 days, IP A, F
Activity B, 40 days, IP N
Activity H, 10 days, IP = E, M
Activity K, 14 days, IP = E, M, B
Activity D, 11 days, IP = B
Activity R, 10 days, IP = B
It has been calculated that LS(K) = 118, LS(D) = 109, LS(H) = 124, LS(R) = 116.

- Freed works for a traditional company that expects him to start at 8.30 a.m. and leave at 5.30 p.m. or later every day. Most of his work is done on a project basis and, as a manager, he is responsible for the quality of work that is produced and for meeting deadlines, as the nature of his work involves meeting deadlines, achieving certain objectives, and hitting targets. On most days of the week, there is often extra work to be done on a project, and Freed stays late in the office or brings his work home. Occasionally, his director and colleagues find him missing important information in a meeting because he was thinking about something else.People sometimes think about something other than what they’re doing.
