Question: AON = Activity on node CPM = critical path method ES = earliest start EF = earliest finish LS = late start LF = late

AON = Activity on node CPM = critical path method

AON = Activity on node

CPM = critical path method

ES = earliest start

EF = earliest finish

LS = late start

LF = late finish

For the project below: a. Construct an AON diagram. b. Construct a CPM network representation. c. Determine the ES, EF, LS, and LF times for the project. d. What is the critical path? e. How long will the project take to complete? f. What activity or activities should you crash to reduce the duration of the project by two weeks? g. Complete the critical path after deciding on this reduction. Crash Normal Additional cost to crash Activity Duration Predecessor Duration an activity (cost/week) (weeks) 1 1 1 2 3 2 2,000 1 3 2 1 3,000 2 4 4 3 1,000 2 5 2 1 500 3,4 6 1 1 5 7 4 3 5 2,500 5000 8 3 2 6,7 9 2 1 500 2 10 1 1 8,9
