Research On The Optimizing Adjustment Of Locomotive Affair Productivity Layout

The locomotive affair productivity distribution is an important part of the whole railway productivity distribution, which focused on space distribution and development law of locomotives, locomotive maintain equipment,locomotive depots,locomotive return depots and human resources under instruction of railway layout theory. A reasonable locomotive affair productivity distribution can enhance the efficiency of the locomotives, realize the optimization of the limited railway resource and optimize the railway economic and social benefits.For the past few years, railway transportation faces intense market competition, which as well the opportunity for railway to deepen reform.Although railway reform has already made important progress, the task is still arduous.This requires locomotive system as the " engine " of railway transportation to shoulder history responsibility for railway reform and development.In the planned economy, Chinese locomotive affair distribution is formed with railway lower economic and technological conditions. There were great unreasonable situations in the locomotive affair productivity distribution.In order to achieve railway leaping development, although some progresses have been made in the several times of adjustment to the locomotive affair productivity distribution, there is still a large gap to the development requirements, which restricted the development of railway advanced productive forces.Based on the present situation and main problems as well as development direction of Chinese locomotive affair productivity distribution, the paper proposed the optimal adjustment strategy of locomotive affair productivity distribution to make the locomotive affair productivity distribution more reasonable.The main contents in the paper include:1. The locomotive affair productivity distribution generality.On the basis of development history of locomotive affair productivity distribution in our country, overall introduction of theory includes the following content:connotation, foundation, research ideas, goals and principles of locomotive affair productivity distribution.2. The optimal adjustment ideas and principle of locomotive affair productivity distribution.Based on the analysis about affecting factors of locomotive affair productivity distribution, and combined with present situation and main problems as well as development direction of Chinese locomotive affair productivity distribution, this paper focused on overall goals, guiding ideology, adjustment idea and principle of the locomotive affair productivity distribution in order to generate support conditions.3. The adjustment of locomotive circulation optimization. Reform of locomotive circulation optimization is a very important issue in the adjustment of locomotive affair productivity distribution optimization.Adjustment of locomotive affair productivity distribution is meaningless without long circulation and crew pooling system.First of all, generate the most possible locomotive long circulation optimization in the solution space as "alternative set" according to certain principles. Secondly, an optimization adjustment strategy is proposed and a rough set-based extension multi-objective decision making model is established based on the "alternative set" to get the best plan.The study not only is a breakthrough for adjustment of locomotive affair productivity distribution, but also fills the blank in the implementation of the locomotive long circulation theory system and framework.Along with the long circulation application, adjustments should also be made for working plan of the train attendants under the limits of working hours.Based on this, this papers sets up working hours limit standards through the entropy and relative entropy theory.4. The locomotive depot distribution optimization integration strategy. Function of locomotive depots should be redefined after the long circulation application, such as removal and merger locomotive depots and turn-back depots, improve technical equipment level of key locomotive depots to realize brand-new situation of locomotive depot modernization.Instructed by integration and coordination, the locomotive distribution optimization is regarded as an integrated system, applying coordination decision-making with the integration management theory, by using entropy theory, relative entropy principle and dynamic multi-value assembly theory, a multi-agent multi-objective two stages decision-making model to locomotive depot distribution problem is built. Meanwhile, this paper puts forward locomotive depot adjustment principle to minimize the total number of locomotives.Integration in locomotive depot is also analyzed on the formal basis.5. The optimal adjustment of the locomotive maintenance distribution.Optimization adjustment of the locomotive maintenance distribution is an important part of integration in locomotive depot as well as key issue to promote economic benefits and social benefits. Adjustment of the locomotive maintenance distribution should be made after the Locomotive depot distribution optimization to establish a modernized locomotive maintenance base. This paper take this problem as a bi-level programming of location problems, establish locomotive maintenance distribution optimization model and design double iterative optimization algorithm to solve the bi-level programming model.6. The evaluation of optimal adjustment locomotive affair productivity distribution. First of all, base on the feature of locomotive affair productivity distribution adjustment post-assessment, an evaluation system on the locomotive affair productivity distribution adjustment is built.Secondly, the application of the dynamic multiple value background principle to dynamic index and the entropy method is proposed to evaluate indexes weights. Finally, by application of the extension theory, a matter-element extension evaluation model for effect of locomotive affair productivity distribution adjustment is established by using the matter-element transformation.Through the readjustment of the evaluate the effects of information, feedback continuously be gotten to improve the adjustment strategy to further scientific adjustment planning of locomotive affair productivity distribution.The study does not only have practical significance to the locomotive affair productivity distribution optimization adjustment, but also make a reference to further exploit railway transportation capability in China.
