To draw the network plan, we will follow the precedence rules given in the table.
Step 1: Identify initial activities and draw the start node. Activities E, G, and H have no preceding activities, so they all start from a common initial node (Node 1).
Step 2: Draw activities with single predecessors. • Activity F is preceded by E. So, F will start after E is completed. • Activity I is preceded by F. So, I will start after F is completed.
Step 3: Draw activities with multiple predecessors. • Activity J is preceded by G, H, and I. This means G, H, and I must all be completed before J can begin. We will use a merge node to represent this.
Step 4: Complete the network with the final activity and end node. Activity J is the last activity, leading to the final end node.
Here is the network plan based on the precedence table:
\begin{tikzpicture}[node distance=2cm, auto, thick] % Nodes \node (start) [circle, draw] {1}; \node (E_end) [circle, draw, right of=start, xshift=1.5cm] {2}; \node (G_end) [circle, draw, below right of=start, yshift=0.5cm, xshift=0.5cm] {3}; \node (H_end) [circle, draw, below right of=start, yshift=-0.5cm, xshift=0.5cm] {4}; \node (F_end) [circle, draw, right of=E_end, xshift=1.5cm] {5}; \node (I_end) [circle, draw, right of=F_end, xshift=1.5cm] {6}; \node (J_start) [circle, draw, below right of=I_end, yshift=-1.5cm, xshift=-1.5cm] {7}; % Merge node for G, H, I \node (end) [circle, draw, right of=J_start, xshift=1.5cm] {8}; % Edges (Activities) \draw[->] (start) -- node {E} (E_end); \draw[->] (start) -- node {G} (G_end); \draw[->] (start) -- node {H} (H_end); \draw[->] (E_end) -- node {F} (F_end); \draw[->] (F_end) -- node {I} (I_end); % Merge for J \draw[->] (G_end) -- (J_start); \draw[->] (H_end) -- (J_start); \draw[->] (I_end) -- (J_start); \draw[->] (J_start) -- node {J} (end); \end{tikzpicture}The network plan is shown above. \text{See diagram above}
