Problem $2$

For the activity$-$on$-$arrow $($AOA$)$ network information given below:

a$.$ Construct an arrow diagram.

b$.$ On the diagram, compute the early and late event times $($TE and $TL)$ and event float $($EF$)$ for each node. Use event times to determine the four floats $(TF,FF\frac{,}{\text{I}}NTF,$INDF$)$ for each activity. Identify the activities on the critical path and the project duration.

Calculate and show results on the diagram in the following form:

$\backslash$table$[[i,j,$ACT,$T_{ij},i,j,$ACT,$T_{ij}$
