Resource-time analysis of transport-technological cycles based on GERT-network modeling

The article presents a method for resource-time analysis of transport-technological cycles based on GERT modeling. Two models are considered: the basic GERT taking into account only the time factor and the extended MTP-GERT (Multiple Transfer Parameters GERT) taking into account the time of operations and consumed resources. Methods for analyzing the uncertainty of the process of implementing transport-technological cycles are proposed: based on variance for single-factor analysis and based on covariance for multifactor analysis. It is shown that the method based on covariance allows obtaining a more complete picture of the influence of various factors on the uncertainty of the process of implementing transport-technological cycles. The use of this approach makes it possible to identify critical operations of the transport-technological cycle and provide decision makers with reliable information for process optimization. The results of the study can be used to improve the efficiency of complex technical systems management.
