METHODS AND RESULTS OF CARGO TRANSPORT OPERATION EFFICIENCY EVALUATION IN COLD CLIMATES

Abstract

Existing methods of maintenance periodicity adjustment don`t take full account of the negative impact of factors on which the operation efficiency of cargo transport and drivers’ safety on the route depends. The problem of ensuring the efficient use of cargo transport and drivers’ safety in complex operating conditions is highly relevant. The PURPOSE of the work is formation of the severity levels of cargo transport operating conditions depending on the factors that limit their reliability, as well as improvement of the methodology of maintenance periodicity adjustment using remote diagnostic tools. METHODS. The study uses an a priori ranking method, a correlation-regression analysis as well as the methods for determining the accumulation rates of the vehicle load effect. RESULTS. Four levels of operation condition severity have been identified including acceptable, averaged, increased and critical. The mathematical models confirming their existence have been obtained. The values of the load effect for the different severity levels of cargo transport operation have been determined. CONCLUSION. The results obtained provide an opportunity to form the maintenance mode adjustment factors for different brands and models of cargo transport taking into account the operating conditions.
