Answer from: CobyHageman

a. The normal project length is 36 weeks.

b. The critical path in this project is A-C-E-F.

c. The activity that you choose to crash first to reduce the duration of the project by one week is E because it has the least expediting cost/week amongst A, C, E, F.

d. The project length if all activities are crashed to their minimum is 23 weeks.

e. The slack for activity D is 5 weeks.

Explanation:

a) The normal length of the project = completion time of last activity = 36 weeks.

b) The criteria for critical activity:

$LC_{i} = ES_{i} ,\\LC_{j} = ES_{j} ,\\$

$ES_j - ES_i = LF_j - LF_{i} =$ duration of the activity

where ES = Earliest start time, EF = Earliest finish time , LC = latest completion time, LF = latest finish time ,

The suffix- i refers to the preceding node, suffix-j refers to the succeeding node.

activities satisfying above all criteria are A, C, E, F

therefore critical path is A-C-E-F.

c) To reduce the project duration by 1 week. we should choose to crash among critical activities A, C, E, F. thus we choose to crash activity E because it has the least expediting cost/week amongst A, C, E, F.

d) if we crash all the activities to their minimum, then the project length = sum of crash time of all critical activities

= [6 + 10 + 6 + 1]

= 23 weeks.

e) The slack of activity d = LS - ES = 34 - 29

= 5 weeks

The critical path is given in the diagram,

Answer from: Quest

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
