Abstract: Continuous construction project cycle is long, large investment and a lot of participants, the internal and external factors, involving a lot of unpredictable change easily to project design. This paper respectively from the perspective of the owner, designer, contractor, this paper expounds the formation of design change, analyze the design change might brings to the project schedule, cost, and combined with practical engineering cases and widely existing problems, and from the owners' perspective, how to realize the control and management of design change are expounded, and gives corresponding solutions.

Abstract: Economic development is one of the targets of the whole human society. In macroeconomic theory, the developments of the economy are largely driven by consumption, investment, government purchases. In economic theory, we usually use to describe the development of economy, GDP and GDP will be affected by the price level. To measure the price level, we generally use the consumer price index, commodity retail price index to describe; Investment is usually measured with fixed asset investment and gross value of industrial output. In this article, through nearly 20 years in China's gross domestic product (GDP) and gross domestic product (GDP) of some important indicators, such as the residents' consumption level, the fiscal expenditure, gross value of industrial output and commodity retail price index, the consumer price index, urban residents' income, rural residents income, such as the total energy consumption data, using SPSS software to provide the descriptive analysis, factor analysis, regression analysis and other methods of data carried on the thorough analysis, and analysis the problems reflected by some targeted Suggestions are given.

Abstract: As the development of world economy, how to realize the reasonable vehicle logistics routing path problem with time window constrain is the key issue in promoting the prosperity and development of modern logistics industry. Through the research of vehicle logistics routing path 's demand, particle swarm optimization with a novel particle presentation is designed to solve the problem which is improved, effective and adept to the normal vehicle logistics routing. The simulation results of example indicate that the algorithm has more search speed and stronger optimization ability.

Abstract: In this paper, the use of gray relational analysis theory and methods, Evaluation for agricultural logistics and enterprise performance evaluated. The results obtained using the comprehensive evaluation can provide an objective for the logistics enterprise managers, rational basis for decision making. Innovation of this paper is to use gray relational model to widen, the calculation methods of gray correlation degree of improvement.

Abstract: China is a big agricultural country, effective prediction of peasants’ income is very important. This study mainly uses the SVM theory to predict the peasants’ income. By analyzing the influence factors of peasants’ income, establishes the index system, that is corresponding relationship of peasants’ income and factors of social influence, According to this index system, designs the prediction method of peasants’ income based on SVM. Bases on the statistical data of social factors and peasants’ income between 1990-2012 in china, to train the SVM model, at the same time, the kernel function and parameters of SVM used were setting and compared. The experimental results show that the accuracy of RBF function is 90.7%, the time is 98ms, has higher accuracy and faster computing speed.

Abstract: The third party logistics enterprise acts as an important role in financial logistics and a great loss will be brought to other participants by its default. Therefore, reducing the default above is the key to carry out the financial logistics. this article, by the game analysis of the decision-making in banks and logistics companies which is the financial logistics main body, the factors affect the default of the logistics enterprise are presented, and the model is verified by actual cases. Thus, a reference for other financial institutions to implement the financial logistics is provided, and finally, lessons are supplied for the financial logistics to develop better.

Abstract: By means of questionnaires, the construction design of Logistic data model to analyze the impact factors of farmers' participation in agricultural mechanization investment behavior to verify the theory analysis using SPSS method of data. According to the research and the empirical analysis results show that, at present, the investment of agricultural mechanization is the main means for the development of agricultural modernization; farmers have become the main body of agricultural mechanization investment. Dongliao County agricultural mechanization development present situation, puts forward the main countermeasures of county level of agricultural mechanization development, and make the development of agricultural mechanization effective solutions to provide decision-making reference.

Abstract: Strong seasonality in demand, a short life cycle, and the constant introduction of new products make the demand of movies one of the main strategic decisions taken by movies’ distributors. This paper provides a rich assessment of the demand characteristics for movie theatre attendance. Taking into account the factors such as star, budget, release time, sequence, producing county and etc, a gray relationship approach is introduced to find the main factors that influence movie demand. Our research shows that the audience demand and sequel factors had the highest correlation. The correlation degree of attendance people and distribute copies is relatively high. Moreover, the more stars and the higher investment, will bring the more audience demand. The computing results will help the operators to maximize revenue.

Abstract: The principal component analysis (PCA) is applied in this paper, since the existing power consumption prediction models of cement manufacturing influenced by many factors are quite complex and have low accuracy. In this way, four new key factors affecting the power consumption of cement manufacturing are obtained instead of the eleven original ones, with the complexity of the computing model simplified. Built upon this is the power consumption prediction model of cement manufacturing based on an improved multiple non-linear regression algorithm. Then the efficiency of the model, obviously improved the forecasting precision, is verified in Pingyi Zhonglian Cement Plant. In other words, a theoretical basis for cement plants power consumption forecasting management is provided in this paper.

Abstract: Currently there is a large gap in the level of socio-economic development across regions in Taiwan and inter-regional economic disequilibrium prevails. 23 cities (counties) in Taiwan were taken for example to analyze and evaluate the difference in the level of regional economic development. Firstly, based on the principle in selection of indicators for the level of regional economic development, combined with the actual situation of Taiwan's regional economic development and cities (counties) as the evaluation unit, indicators for evaluation were selected in a scientific and reasonable manner and the weight of each evaulation indicator was determined by Delphi method, thus to establish an evaluation indicator system for the level of economic development in Taiwan’s 23 cities (counties). Secondy, the multi-index comprehensive measurement was used to calculate the composite index of the level of economic development of each evaluation unit, and after horizontal, vertical comparison and analytical investigation of the cities (counties), the reasons for the difference in economic development were analyzed (H • H • Nekrasov, "Regional Economics: Theory • Problem • Methods" 1978). Finally, measures were proposed to coordinate the regional development.
