The cost per day of reduction is given: Activity ABCO Wu А с D E F Immediate Predecessor None None A E A,B C,D Normal Time (days) 3 4 3 2 2 4 Cost/day 450 300 200 100 500 600 Lower Time Limit 1 2 1 1 1 3 For example, activity C can be crashed from its normal time of 3 days down to as little as 1 day or anywhere in between; the cost per day to crash C is 200. a) Draw a network diagram for this project. What is the critical path? How long will the project take, if no crashing takes place? b) Determine the least cost way to crash activities in order to complete the project in 11 days; in 10 days; in 9 days; in 8 days. c) Suppose the due date for the project is 5 days and a penalty of $500 a day is assessed for each day late.
