Theoretical and Multiple Model of Transport Multi-operational Reconfigurable Processes

Abstract

The aim of the study is to create an adequate and effective in the application theoretical model that describes multi-operational technological processes in railway transport at the level of operations, connections and resources. The article presents a theoretical and multiple operational-event model of the technological process, distinguished by its description in the form of “technology - implementation - a set of events”, adapted to reflect changes in technology and processes, as well as the possibility of narrowing multidimensionality and the formation of private models. Based on the definition of technology as a process plan, the set of implementations of technology and the set of events in the process are introduced into the expression of a process model. To analyze the options for implementing the technology, the concept of spatial-temporal process reconfiguration is used as a change in the relative position of its operations. The possibilities of obtaining private models by narrowing the multidimensionality of the complete process model are presented. A formal system of defects in the process is developed on the basis of the set-theoretic formulation of a defect. It is shown that the use of the theoretical and multiple operation-event model of processes allows solving actual engineering problems (formalization, schematization, standardization, visualization) and is promising for developing mathematical and algorithmic support of automated monitoring and diagnostic systems.
