Originální abstrakt

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.
