Unit 9: Simulation of a PERT Network (I)

8. Activity Networks and PERT Charts are typically used to …………… complex projects in Notes
a visual manner.
9. Once the Activity (PERT) chart has been completed, the last step is to review and ………………
the chart.
10. Networks can be connected to other ……………… to work together in completing a task.
11. The ……………… is a database model imagine as a flexible way of representing objects
and their relationships.
12. The first test was made in 1958, when CPM was applied to the construction of a new
………………

13. The Key Concept used by ……………… is that a petite set of activities.
14. Activities with ……………… Total float are on the Critical Path.
15. The PERT approach is useful, because it can contain the ……………… in event completion
times.
9.9 Review Questions

1. CPM/PERT has been rightfully accorded due significance in the literature on Operations
Research and Quantitative Analysis.

2. Analyze what the major step for drawing the CPM/ PERT network?
3. “Performing more critical activities in parallel”. What do you mean’t by this statement?
4. Do you think the critical path method considered only logical dependencies between
terminal elements?
5. All the preceding activities must be completed previous to the project can begin. Is this the
rule for analyzing the activity network? Why or why not?

6. Activity Network and Project Evaluation and Review Technique, or PERT, charts are a
way of documenting and examine the tasks in a project.
7. Is it possible to decrease the critical path of a project? How?

8. “PERT assumes that the expected length of a project is purely the sum of their separate
expected lengths.” Explain.
9. Do you think a PERT chart is a tool that ease decision making? If yes then why?

10. A network diagram can be created by hand or by using diagram software. So which
software is used in network diagram?
