Dave Fletcher was able to determine the activity times for constructing his laser scanning machine. Fletcher would like to determine ES, EF, LS, LF, and slack for each activity. The total project completion time and the critical path should also be determined.

The company decided that the project in the previous problem had to be expedite in order to optimize (minimize) the project cost. Expediting can be used to trade direct cost for indirect cost, since expediting reduces the indirect cost of the project by a fixed amount per day, while expediting an activity increases its total direct cost. The Accounting Department found that indirect costs amount to $100 per day, while activity direct costs as well as their normal and expedited times are given in the table below. Activity Duration (Days) Expedited Time (Days) Normal Direct Cost ($) Expedited Direct Cost ($) A 32 26 200 500 B 21 20 300 375 C 30 30 200 200 D 45 40 200 800 E 26 20 700 1,360 F 28 24 1,000 1,160 G 20 18 400 550 What is the optimal time to complete the project?

I need a detailed explanation and assistance to solve this problem: A company decides to plan a project, with activities, precedences and random duration statistics given in the following table: Activity Immediate Predecessors Duration Minimum (weeks) Duration Mode (weeks) Duration Maximum (weeks) A none 2 5 9 B A 1 6 8 C A 3 5 12 D B 2 4 12 E B, C 4 6 8 F B 6 7 8 G D, E 1 2 6 H F, G 4 6 16 * What method should be used? Compute the mean and variances for each activity and add them to the table above * Draw the project network and label the arcs with the activity name. * Assuming that the critical path is AàBàP1àEàGàH, compute the probability that this path duration is between 28 weeks and 32 weeks. * Assuming that the critical path is AàBàP1àEàGàH, compute the number of weeks within which the project will be completed with probability 0.95.
