This helps you to minimize cost while still achieving your objective.

The formula below to calculate the estimated time for each project stage:

a + 4m + b
----------------------------------
6

(a- Optimistic time, m- Normal time, b- Pessimistic time).

2. Draw a network of lines and circles showing the relationships between events.

3. Each circle should be labeled with the number of its step.

4. A line represents the time that each event takes. Each line should
