Risk Analysis in the Appointment of the Trucks’ Warranty Period Operation

Reliability is currently one of the factors affecting the competitiveness of vehicles. Vehicles become highly reliable due to the integrated approach to all stages of their “life cycle”: design, production and operation. The most important for the manufacturer is the warranty service, because this stage is characterized by an increased probability of failure, and the manufacturer takes responsibility for their elimination. The authors propose to take into account the risks of failures of various units, assemblies and systems of the car during the appointment of the warranty period. This study used the statistics of failures received from the dealer and the service network, and from the reliability department of the engine manufacturer. The results of the study show that the use of the proposed methodology will reduce the costs of the truck manufacturer.

Intellectualization of the Spare Parts Supplier Selection by the Analysis of Multi-criterial Solutions

The quality of automobiles efficiency maintaining is largely determined by the effectiveness of providing system of dealer and service centers with spare parts. It is necessary to analyze the characteristics of suppliers and the distribution of flow requests for spare parts, taking into account reliability factor of the supplier by the control center of the firm service system. The authors proposed a methodology for multi-criteria evaluation of the spare parts suppliers, which is determined not only by the reliability of compliance with the terms of supply and the organization of logistics processes, as well as the reliability and quality of the spare parts themselves. Also, in order to assess the probability of fulfillment of obligations by the new supplier, a methodology for forecasting such indicators characterizing the supplier’s reliability, as the delivery time, the spare part quality and the level of shortages, is described with usage of logistic regression.

ITS Safety Ensuring Through Situational Management Methods

The paper is devoted to solving the problem of complex organizational and technical systems’ (COTS) safety improvement with the use of methods of situational management. The possibility to manage COTS with the use of decision support system, the intelligent core of which contains the object model of the precedent describing unwanted processes in the COTS, is considered. The object-oriented hierarchy model of the vehicle as a complex dynamical system is developed. To improve reliability and safety of the COTS the database of precedents is established. Precedents in this database are presented according to the developed model by which the analogues search procedure is performed and the best managerial decision is chosen.

Interactive (Intelligent) Integrated System for the Road Vehicles’ Diagnostics

Existing organization schemes of the vehicles’ diagnostics are considered in the article and interactive complex vehicle diagnostic system is proposed on the basis of this analysis. The diagnostic algorithm is presented. To implement it, the intelligent diagnostic system based on monitoring the residual life of the vehicle’s units and assemblies is developed. It consists of Server of diagnostics, Autonomous information-diagnostic blocks and Display and control unit. Currently, module for collection and processing information is developed. Operational tests of the vehicles when the sensors were installed were carried out together with manufacturer “KAMAZ”.
