Problem 1
Construct the network diagram for a project with
the following activities:
Solution The start event is node 1. The activities A, B, C start from node 1 and none
of them has a predecessor activity. A joins nodes1 and 2; B joins nodes 1 and
3; C joins nodes 1 and 4. So we get the following:
This is a part of the network
diagram that is being constructed. Next, activity D has A as the predecessor activity.
D joins nodes 2 and 5. So we get
Next,
activity E has B as the predecessor activity. E joins nodes 3 and 6. So we get
Problem 2 Develop
a network diagram for the project specified below:
Solution Activity
A has no predecessor activity. i.e., It is the first activity. Let us suppose
that activity A takes the project from event 1 to event 2. Then we have the
following representation for A:
Putting all the pieces together,
we obtain the following diagram the project network:
The
diagram is validated by referring to the given data. Note: An important point may be observed for the above diagram. Consider the following parts in the
diagram
We took nodes 6 and 6l as one and
the same. Instead, we can retain them as different nodes. Then, in order to
provide connectivity to the network, we join nodes 6l and 6 by a dummy
activity. Then we arrive at the following diagram for the project network:
