ВВЕДЕНИЕ В ИСПОЛЬЗОВАНИЕ СЕТЕЙ ПЕТРИ ДЛЯ АНАЛИЗА ЛОГИСТИЧЕСКИХ СИСТЕМ
The purpose of this article is to show the possibilities of using stochastic Petri nets for the logistic systems analysis in order to optimize their operation. This article deals with the mathematical apparatus of Petri nets, moreover, it also shows an algorithm for making performance analysis. As an example, the simplest model of unloading a vehicle was developed and analysed to determine the main characteristics of a given model. In order to perform the performance analysis of given Petri net, the state space of this network was constructed and a state space stationary distribution of the the system was found analytically. That allowed to determine the key parameters of the model; Performance analysis was performed without using third-party software. As a result, it has been shown that Petri nets are a simple and convenient tool for logistics systems optimization and design. Therefore, Petri nets can be used as a support mechanism for decisions making at various levels of supply chains.
