Forecasting the release on the line of variously aged long haul vehicles in Russia

At the process of purchasing vehicles, carriers usually choose up between brand new and used vehicles. Essential delays on loading-unloading goods dramatically affect the intensity of long-haul transportation in Russia and in East European countries, stimulating carriers to purchase used vehicles, which generally need replacement on much frequent basis. In case of purchasing long-distance haulage vehicles, it is essential to have evidential information regarding its possibility for sustainable long-term usage, including maintenance constraints and possible financial loses. As an indicator of maximum number of days in operation per year, the potential coefficient of the released vehicles on the line is proposed. The coefficient was performed also in relation with dependence of truck age. As a practical result, for VOLVO tracks in Russia, the optimal 5-year exploitation period for vehicles has been determined.
