Studies On Evaluation Of Benefits On Hi-Tech Equipments Of Railway Transportation

Whether the railway industry can develop quickly, healthily, consistently, and whether it can complete the goal of span development relate to the main body of the prospect of national economy directly. Because the development and application of the railway transportation hi-tech equipment is very important for this system, so for the railway industry enterprise competing with its counterpart, how to evaluate the benefit of the railway transportation hi-tech equipment impersonally, scientifically and effectively has the special important realistic meaning for realizing its technology innovation capacity scientifically, adopting the stratagem of the technology innovation properly, improving its competitive predominance, and getting the optimal economic benefit, social benefit, technology benefit and quality benefit. The major idea of the paper is to evaluate and analyze the benefit of the railway transportation hi-tech equipment. Based on it, the comprehensive evaluation method is also discussed in the paper.Firstly, the paper sets forth the development of the evaluation theory, and limit the meaning of hi-tech. Meanwhile, the development condition of the railway transportation hi-tech equipment home and abroad are also introduced in the paper. Secondly, aimed at the character of the railway transportation hi-tech equipment, the evaluation index in four respects including economic benefit, social benefit, technology benefit and quality benefit are devised and it settles a foundation for the latter comprehensive evaluation. Thirdly, aimed at the guidelines including rationality, availability, science and practicality, the paper brings forward the system of comprehensive evaluation index and no dimension method according with the actual condition. And at the same time, after summarizing, evaluating and analyzing the relative evaluation method, two mathematics models: entropy method and BP neural network method are confirmed to be the synthesis evaluation method for the railway transportation hi-tech equipment. At last, two cases are demonstrated and analyzed including the railway online computerized ticketing system of Guiyang railway station and the electric locomotive products manufactured by Zhuzhou electric locomotive factory of the South Locomotive Group, and the evaluation result is accord withthe fact, so the correctness of the idea and method brought forward by the paper are validated.At present studies on the evaluation of the benefit of the railway transportation hi-tech equipment home and abroad are still in the underway phases and the system theory has not come into being yet. Based on the related production of the academia been derived, the paper makes the following innovations: Firstly, the paper anatomies the four influence factor of the benefit evaluation of the railway transportation hi-tech equipment, including economic benefit, social benefit, technology benefit and quality benefit, the index system of the comprehensive evaluation is also designed. Furthermore, the evaluation idea of BP neural network and entropy method are introduced for the first time in the benefit evaluation field of the railway transportation hi-tech equipment, and through the computing and analyzing of the cases, the evaluation results achieved are demonstrated according with the fact. So the paper also has the guidance meaning in the practice of evaluation and decision about the railway transportation hi-tech equipment.
