Consider the below project table for the Project Crashing

a) Draw the precedence network diagram.

b) Compute the critical path, associated time and cost (normal time).

c) Reduce the project duration to 26 weeks at minimum cost? What is the critical path and cost?

d) Reduce the project duration to 23 weeks at minimum cost? What is the critical path and cost?

e) What is the minimum and maximum number of activities to be crashed to reduce a 1-day duration on the project?

f) What is the total number of activities (and what are those) and how many crashing steps need to be done to reduce the project to 24-weeks duration?
