Application of DEA models in efficiency evaluation of the KAMAZ vehicle robotic system

摘要

Abstract The problem of evaluating the effectiveness of a robotic system of agricultural vehicles is described. A robotic system is considered, including robotic chassis for fieldwork, for transporting goods in the territories of agrarian production and specialized cars. An important task is to evaluate the reliability of robotic vehicles during the operation. A model-oriented approach to monitoring and analyzing the technical condition of the vehicle is proposed. The data envelopment analysis technique is used with the solution of a non-parametric linear programming problem. The selection of input and output parameters of a model of a robotic vehicle is described. The mathematical formulation of the linear programming problem by the integral criterion for the functioning of a robotic car in different periods is given. The results of the experimental studies are presented. The application of the data envelopment analysis allows determining the vehicle parameter’s target changes. The results will be used in the decision-making system for the operation and maintenance of KAMAZ agricultural vehicles.
