Uncertain graph as the model of branching technological process

Abstract

This paper discusses methods of modeling of branching technological process (BTP) under uncertainty based on uncertain graphs. Simulation of BTP involves the formation of the graph and its modification in case of restructuring of BTP. This formalization takes the form of operations on uncertain graph. To use undefined graph as the model of BTP in decision support system (DSS) the concept of transition uncertainty function between states and transition risk uncertainty functions is introduced. Model of BTP as uncertain graph in combination with certain operations on graphs and operator method of uncertainties conversion is described as convenient basis of creating DSS in management systems of BTP.
