SYSTEM FOR EVALUATING ECO-EFFICIENCY OF ROLLING STOCK

摘要

An echo-efficiency evaluation system of a railroad car is provided to evaluate the environmental load and operation capability of the railroad car generally and easily in real time and compare relative echo-efficiency values applying the railroad car of the same standard for a plurality of object railroad cars, thereby determining the merits and demerits relation of echo-effectiveness among the object railroad cars at a look. A storage medium(110) records a database which includes the environment load index data of a standard railroad car, the service performance index data of the standard railroad car, and the environment load index data of an object railroad car, and the service performance index data of the object railroad car. A unit for producing a relative environment load index(120) calculates the average of the rate of change in the environment load index of the object railroad car based on the environment load index of the standard railroad car, and outputs the calculated average as the relative environment load index of the object railroad car. A unit for producing a relative service performance index(130) calculates the average of the rate of change in the service performance index of the object railroad car based on the service performance index of the standard railroad car, and outputs the calculated average as the relative service performance index of the object railroad car. A unit for producing relative echo-effectiveness(140) calculates a ratio of the relative service performance index for the relative environment load index, and outputs the calculated ratio as the relative echo-effectiveness of the object railroad car.
