Explanation / Answer
1. Weighted score for projects
Project 1 : 10x0.25+ 6x0.1+ 8x0.3+ 7x0.2 + 9x0.1+ 8x0.05 = 8.2
Similarly
Project 2 : 7.2
Project 3 : 8.5
Project 4 : 7.7
Project 5 : 7.8
Project 6: 7.5
Project 3 should be selected, score being highest.
Ans 2: As it is seen BCEI is the critical path with duration of 17 days, which is the least time in which the project can be completed.
Ans 3 : The implementation time can be reduced by crashing the activities B, C or E to the minimum possible duration. E can be crashed for 3 days without critical path being changed. If it crashes for more than 3 days, F and G will also need to be crashed to keep BCEI as critical path.
