Original Abstract

The paper generally deals with the effects of a change in variance activities when computing the criticality node of a PERT network diagram. The main aim of the paper is to analyze the effects of a change in variance activities for two different approaches used when computing the criticality node. In order to achieve the aim, a hypothesis is formed that the change in variance activity should affect the computation of the criticality probability of nodes. The analysis is applied to a sample PERT network diagram comprising 9 nodes and 14 activities. A time analysis is developed using the PERT method, and the criticality node is computed using both approaches. The computed results serve as input for further statistical processing.

Keywords

PERT method, node criticality, mean value, variance, standard deviation, hypothesis testing.
