Problem 2. Construct a project network with the following precedence relationships: \begin{tabular}{|c|c|c|c|c|} \hline \multirow{2}{*}{ Activity } & \multirow{2}{*}{ Immediate Successor } & \multicolumn{3}{|c|}{ Duration } \\ \cline { 2 - 5 } & Optimistic & Most Likely & Pessimistic \\ \hline A & E, F & 8 & 10 & 12 \\ \hline B & C, D, E, F & 1 & 1.5 & 2 \\ \hline C & H & 12 & 14 & 16 \\ \hline D & G, H & 2 & 4 & 8 \\ \hline E & G, H & 5 & 6 & 9 \\ \hline F & & 0.5 & 1 & 3 \\ \hline G & & 6 & 8 & 11 \\ \hline H & & 1 & 1.5 & 3 \\ \hline \end{tabular} If the total available resources for this network are 3 units and the resources required for activities A through H are as follows: i. Find the duration to complete all activities using the ACTIM approach. ii. Find the duration to complete all activities using ACTRES approach
