Consider the project described by the table below where all durations are in days and, the normal and crash costs are in Ghana Cedis. In addition, there is a fixed cost of GHC1000 for each day on site. a Activity Predecessor Crash Time A B C D E F G H I J K L A B C D E F G HI JK Normal Time 2. 13 19 18 13 10 18 6 4 13 15 4 Normal Cost (GHC) 2,000 2,000 2,000 2,000 2,000 2,000 2,000 2,000 2,000 2,000 2,000 2,000 2 10 15 15 11 9 14 5 3 12 Crash Cost (GHC) 2,000 2,300 3,000 3,000 3,000 3,000 4,000 3,000 3,000 3,000 3,000 2,000 13 4 2. Draw a network diagram together with the activity schedule for the project. (8 marks) b.Suppose activity K were to be delayed by 4 days. What will be the impact on the project completion time and the total cost? Assume cost of performing an activity does not change despite the delay. (5 marks) c. If the project is to be crashed, what is the earliest time it must be completed at the minimum cost possible? (12 marks)
