Conceptual model of the estimation of the efficiency of the driver-car-road- environment system

This article discusses a conceptual model for evaluating the effectiveness of a DCRE system. The conceptual nature of the proposed model for studying the DCRE system is substantiated. There are enough studies related to the assessment and improvement of the reliability of the DCRE system. However, it is not always possible for the DCRE system to be comprehensively characterized by its reliability. Consequently, its effectiveness can be considered as a more important indicator characterizing a DCRE system, and the reliability of a DCRE system remains a fundamental factor in evaluating its effectiveness. It is proposed to investigate the effectiveness of the DCRE system on the basis of the fundamental laws of nature. As in many cases, the application of the law of conservation, transformation and transfer of energy is appropriate for assessing the effectiveness of the DCRE system. DCRE systems can be categorized as large and complex. It contains ambiguous relations and patterns of interconnection between its elements. Due to the multi-criteria of the DCRE system, the processes occurring in it have a stochastic character. The DCRE system is classified as complex because of its multidimensionality, the diversity of the nature of the elements, the connections, the heterogeneity of the structure, and also because the system functions under conditions of significant uncertainty of the environmental impact. Its complexity is exacerbated by the random nature of changes in its indicators. In this model, the assessment of the efficiency of the DCRE system takes into account the complex stochastic nature of the transformation and transfer of energy within a particular subsystem and between subsystems. Consequently, for this case, it is proposed to apply probabilistic-statistical methods for evaluating the effectiveness of the DCRE system. The article proposes a differential equation for calculating the efficiency of the DCRE system, taking into account the peculiarities of the conditions of operation of heavy vehicles in mining and alpine quarries.
