Network Plan and Monte Carlo Method

Revision as of 14:02, 17 September 2017

Abstract

This article is an application oriented in-depth description of a Network Plan, in regards to project planning. The Network Plan diagram is a visualization of the time plan, after having formulated an ideal WBS, which can reveal the Critical Path for the project time plan. Furthermore, the Network Plan diagram will reveal which WBS areas has time buffers, which ideally can be utilized to redirect human resources, in case of time critical situations. There exists software to create time plans, e.g. “Microsoft Project” and many more. In practice, the project time plan is often determined from rough estimates or experience of needed time in different WBS areas. This article will describe the functionality of a Network Plan Diagram and how the diagram is created. Furthermore, the article will describe how more realistic estimates of time consumption in different WBS areas could be obtained, by the use of the statistical tool called Monte Carlo method.
