Since middle 1960s methods of network planning and running have become one of the decision-making tools. The networks (graphs) are used to formulate and solve different practical issues connected with implementation of activities (events) sequence. Some of these issues have become axiomatic. Development of programming tools led to these methods recovery based on the modern technologies, which allows a researcher to provide fast and reliable forecasts of the under-study processes behavior. The Business Process Model and Notation (BPMN) have been developed and widely used. BPMN is notation of business processes modelling, which is the interface between business process formalization and its practical implementation. The notation is represented as the number of graphical elements which are used in business processes description. It is often used for description and formalization of business processes on easy-to-understand level. But BPMN also allows you to automate the company activity. The algorithm of object-oriented network model is considered in the paper. The model is applied to maritime transport business processes which conveniently can be described in BPMN. Application of the approach particularly means building the networks simulation model. This allows you to provide stochastic analysis of business processes in the case of stochastic nature of the processes implementation and alternative critical paths. The authors believe that the model can be widely used. The stochastic nature of the weights of the network model edges, as shown by experimental tests of the approach presented in the paper, allows one to observe changes in the critical path. This ambiguous solution allows, in principle, to rationally reserve the necessary resources.
