1. Using the network diagram only , find

Shortest task first

Minimum slack first

Most critical followers

Most successors

2. Using the network diagram and the additional information below, find

The crash cost per day

Which activities should be crashed to meet a project deadline of 13 days at minimum cost. Assume partial crashing is allowed.

3. Reconsider Question 2 above, assuming a fixed overhead cost of $30 per day but no project deadline. What is the leastcost crash program? What if the overhead cost was $40? What if it was $60?

\begin{tabular}{|l|c|c|c|c|} \hline Activity & Crash Time (days) & Crashed Cost (total) & Normal Time (days) & Normal Cost \\ \hline A & 3 & $500 & 4 & $300 \\ \hline B & 1 & 325 & 3 & 250 \\ \hline C & 4 & 550 & 7 & 400 \\ \hline D & 3 & 250 & 5 & 150 \\ \hline \end{tabular}
