Abstract: At present, on the basic of the development of global economic integration and the gradual growth of the developed market economy, the Manufacturing Enterprise has become an indispensable force for the growth of national economy. In recent years, affected by a number of factors, including economic globalization, financial risk of manufacturing enterprises in business activities has become increasingly prominent, which has been threatening the survival and development of manufacturing enterprises. This paper which closely combines theory with practice makes a number of useful exploration on manufacturing enterprises how to assess and manage corporate financial risk. Firstly, the author introduces the research background and the significance. Then the paper describes financial risk of manufacturing enterprises and its causes. At the same time, through the specific cases, the paper assesses financial risk of manufacturing enterprises and makes some measures.

Abstract: This document introduces the current status of the stacking and loading technology in major logistics. It introduces the development of a kind of automatic stacking and loading system in major logistics from Chengdu University of Information Technology, including the function, composition, characteristics, key technology of structure design for Non bulk cargo object, automatic extract, automatic loading and stacking. Then the main technical parameters are put forward. It is pointed out that the system has a good social, economic significance.

Abstract: Enterprise financial distress prediction based on neural network has some disadvantages, such as complex structure, slow convergence rate and easily falling into local minimum points. The paper presents the genetic neural network based enterprise financial distress prediction. Firstly, the structural parameters of neural network model are encoded and connected into gene sequence to obtain an individual. A certain number of individuals make up a population. Secondly, after the reproduction, crossover and mutation operations upon the population, the best individual, that is the optimal structure parameters of neural network model, is obtained. Finally, the neural network model with the optimal structure parameters is trained by the training samples and the trained neural network model can realize enterprise financial distress prediction. The testing results show that the method achieves higher training speed and lower error rate.

Abstract: To find the release method of railway station loading capacity information under E-business, the concept of game theory was introduced into analyzing the owners response to guidance information. In this paper, we found the loading operations in station are influenced after releasing information of station loading capacity. Besides, the descriptive information has fewer effects on the balance of loading operations. However, the propositional information makes contributions to distributing cargo flow reasonably which increases the efficiency of station loading capacity.

Abstract: To improve the level of enterprise performance management and logistics service,this paper proposed the KPI evaluation method of logistics service in railway logistics enterprises. By analyzing the strategic target of railway logistics enterprises logistics service, I decomposed the railway logistics enterprises strategic target to get the key evaluation indicators system of the logistics service in railway logistics enterprises, and used AHP to determine the index weight. Finally, I used the percentage method to evaluate the logistics service of railway logistics enterprises.

Abstract: Shanghai Expo, a global event, has enormous influence in a large scope in terms of space and contents. This thesis studies its influence in one aspectthe influence on economy. Based on cost-benefit theory, data fitting and the input-output table of the 2010 World Expo in Shanghai, the thesis has set up a complete mathematical model for quantitative assessment of costs and benefits to analyze the direct and indirect influence of the Expo on the economy of Shanghai. Through the cost-benefit assessment model, we can get the direct economic revenue of the Expo is RMB 1.691 billion Yuan. By data fitting analysis, because of the influence of the Expo, tourism income is 14.69 billion Yuan more than the natural growth and business volume of science and technology is 2.89 billion Yuan more than the natural growth.

Abstract: In view of logistics resources integration, this paper introduces an evaluation method of logistics network infrastructure in railway logistics enterprises. The comprehensive evaluation model is established according to the aspects which demonstrate several key indexes and the relationship between them. To illustrate the effectiveness of the above method and the application of the proposed model, a case is studied that verifies the importance of the research in the logistics theory and practice. It presents an evaluation criteria and evaluation model of logistics infrastructure network. The computational results indicate that the evaluation method in selected case is in decent rank.

Abstract: Highway engineering tender price control is the maximum limit of the construction cost. A reasonable bidding price control is the key factor in controlling the project investment effectively and preventing the bidders bidding up the price, it is also the key to a successful bidding. In this paper, the compilation process of bidding price control is given with practical examples of highway engineering.

Abstract: The thesis first analyzes the failure mechanism of contaminant lock, then the contaminant sensitivity theory or the Omega theory, which is first put forward by the Oklahoma state university hydrodynamic research center, is introduced and being applied to the servo valve contaminant lock life analysis and the contaminant sensitivity test method of servo valve is presented. After that, the value of servo valve contaminant lock sensitivity as well as the contaminant lock life can be calculated. It turned out that this method can accurately evaluate servo valves resistance on pollution lock and contaminant lock life, which can offer guidance on servo valve selecting and reliability analysis.

Abstract: Water Environment Comprehensive Assessment System is a comprehensive system of water environment impact related to a variety of factors, including water and other natural attributes, and human social and economic activities and other social attributes of the water environment giant system merits of a scientific evaluation system, which for the water environment pollution prevention and scientific management decision-making basis. This paper presents the evaluation of water environment system engineering methods, the method takes into account the water environment facilities and managerial factors, etc., may reflect the situation of water environment of the objective entity.
