Abstract
Dynamic model of maintenance management of epartmental fleet of special vehicles
Incoming article date: 30.08.2022The paper considers the model of management of maintenance of the transport fleet of the territorial body of the Penal System of the Russian Federation. Using the theory of queuing, possible states of the system are identified, a graph of states is constructed, a system of differential equations describing the dynamics of the process under consideration is given, taking into account the application of the prioritization scheme when carrying out maintenance and repair of vehicles. In order to refine the model, it is proposed to use a neural network model (multilayer perceptron) to calculate the failure rates and restore special vehicles. Calculation formulas for the implementation of the learning algorithm of the considered artificial neural network by the method of error back propagation are given. The model proposed in the work can be used to build automated decision support systems in the field of operation and repairs, as well as to improve the material and technical support of institutions and bodies of the Penal System of the Russian Federation.
