The following information concems a project to raise money for the kids Against Crime Foundation: Activity Activity Time (days) Immediate Predecessor(s) A 10 B 9 AB D 5 AB E 8 AB F 13 CE G 5 CO H 10 1 6 EG 9 EH K a. 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.80 help Employee, currently assigned to activity. Each week that Employee. A helps Employee will result in activity increasing its time by one week and activity reducing its time by one week How many weeks should Employee work on activity F?

Draw the network diagram for this project. D. Determine the critical path and project completion time. 11. Consider a project to produce custom door moldings for GMC Acadia cross-over vehicles, described in Table 74 Analyzing Cost-Time Trade-offs 12. Table 75 contains information about an environmental clean up project in the township of Hiles Shorten the project three weeks by finding the minimum-cost schedule. Assume that project indirect costs and penalty costs are negligible. Identity activities to crash while minimizing the additional crash costs TABLE 7.5 ENVIRONMENTAL PROJECT DATA Normal Crash Time Time Cost to Crash Immediate Activity (weeks) (weeks) ($per week Predecessor(1) A 7 6 None B 12 9 250 None C 7 6 250 A D 6 5 300 A E B F + 1 CD G 3 1 DE H 3 2 350 F 1 2 2 G a. What is the project's duration if only normal times are used! b. What is the minimum cost schedule? c.

The Advanced Tech Company has a project to design an integrated information database for a major bank. Data for the project are given in Table 7.6. Indirect project costs amount to $300 per day. The company will incur a 5150 per day penalty for each day the project lasts beyond day 14. -Difficult Problem 14. You are the manager of a project to improve a billing process at your firm. Table 2.7 .contains the data you will need to conduct a cost analysis of the project. Indirect costs are $1,600 per week, and penalty costs are $1.200 per week after week 12 a Wisat is the minimum-cost schedule for this project? b. What is the difference in total project costs between the ear liest completion time of the project using normal times and the minimum-cost schedule you derived in part(a)
