With the life style changing, the distribution has become an indispensable part of people. However, the contradiction between the city-distribution's timeliness and the city traffic's capacity as well as the environment stress makes the last one kilometer distribution become a hot topic. On this issue, Based on the mechanism of the resource store, management and feedback, the authors find the city...
This paper is part of a wider work- developed in the context of URBANETS project — Sustainable Management of Urban Networks with the Use of ICT- and of scientific research projects, mainly, on traffic and environmental requirements for Brindisi and Gallipoli. The paper is structured by considering different aspects having as an objective the satisfaction of transport knowledge needs with regard to...
The actual driving data of Dalian city is collected by GPS devices and divided into kinematics sequences. After characteristic parameters of the kinematics sequences are calculated, this paper makes component analysis and cluster analysis to extract the representative driving data. The driving cycle of Dalian is constructed based on the analysis result of the representative driving data. The driving...
This main purpose of this study is to understand the self-seeking behavior of participants in developed kiosks that provides interactive service at Huashan Creative Park in Taipei City. To understand user self-seeking patterns, log data from actual cases of interactive kiosk service were collected and analysed by web usage mining. This study analysed 5724 sessions of 8 kiosks for the month of December,...
In recent years, statistical methods are used more and more in the field of economic and living standard, which is a very important indicator reflecting the degree of society development and peoples' living quality. This paper uses 14 economic and living indexes to analyze and evaluate economic and living standard of China from year 2003 and 2008. The results show that three components can be extracted...
After introducing the past research achievements in the field of automatic selection of road network, the advantages and shortcomings of how to select the road network were underlined, then a new road selection algorithm to fetch up the shortcomings was put forward. First, the assessment criteria of the importance of road network were summarized and classified on the basis of constraints in road network...
Urban wetland ecosystems play in the city to maintain ecosystem equilibrium, wetland ecosystems in maintaining the safety of the ecological functions of wetlands play a huge role. Articles by SPSS statistical software, using factor analysis method and clustering analysis method to select a number of indicators before and after the Songhua River pollution incident on the North Pine wetlands were studied...
The regional economic discrepancy has always been acting as a very important part of the region-economy research. Taking county level of Baiyin as the study unit, the temporal characteristics of the regional economy disparity of Baiyin was analyzed through calculating the standard deviation, extreme difference, coefficient of variation and RHL of per capita GDP of different counties and districts...
Transaction data of Automatic Fare Collection in public transportation record travel time, travel route number of passengers, etc. Analyzing and mining these data, many travel characteristics and laws of transit passengers can be attained, which are important to improve the level of public transit planning and management. Judging boarding stop of passengers is a basis of smart card analysis. Judging...
There are many factors affect the stability of reservoir slopes, each of them is associated and coupled with others. Generally, the analysis of slopes stability can be achieved by the method of effect-factors analogy and cluster analysis. Traditional cluster analysis is difficult to obtain the stable global optimal solution, since the results are sensitive to the initial cluster center and the order...
In the past, the modeling analysis with macro data, although could illustrate the overall changes, can not reflect cooperative relationship between employment and economy, while it is essential to higher vocational colleges because the shown information help to grasp the job market conditions and adjust specialty setting timely. Consequently, through establishing an evaluation index system aimed at...
Logistics system is such a complicated system that establish fair and comprehensive evaluation indexes system and method is the the key for the evaluation of logistics. This paper set up a reasonable logistics evaluaion system on the basis of conbinating with various factors that closely related to the influencing logistics development and then use the factor analysis of multiple statistical analysis...
Combining extension engineering method with cluster analysis, the classic and limited matter elements were constructed according to air quality standards and main air affecting factors. The logical domain was extended from (0, 1)to (-∞ ,+∞), meanwhile, the quantitative analysis in the classic matter-set which only judged by Yes or No was extended to qualitative analysis, which could show the administrative...
This paper uses extension classified prediction to predict monthly average humidity of cities. Using the concepts of matter-element and dependent function to establish prediction model, the prediction results can be obtained by means of cluster analysis. Through analyzing and calculating the historical data of Guangzhou City, the result shows that the extension cluster model in the prediction of humidity...
In the new historic opportunity, it is very urgent to verify, measure and evaluate the location-specific advantages and disadvantages of embedding multi-national corporation value chain in Liaoning province objectively, by using empirical analysis method. The cluster analysis showed that Liaoning's attractive power of market capability is above the average level of the country. And the attractive...
This paper presents the empirical analysis and research on the regional difference of urban residents' consumption structure in china based on generalized main composition and clustering analysis. First introduces 8 resident's urban consumptive indices from 31 provinces and cities to the log ratio analysis which is one of the generalized main compositions in order to bring out a comprehensive index...
The main objective of this study was to make a pollution regionalization of soil heavy metals in A city, an area with rapid economic development in Yangtze River Delta of China. Therefore, the spatial distribution of soil heavy metals was firstly estimated by optimal space method using 126 data points and performed using ArcGIS9.2 software. The areas of different content grade were computed by overlay...
As the gradually deepened of China's economic and social development, the level of China's urban public infrastructure has been significantly increased. This article discusses the unbalanced nature of the development of urban infrastructure among the various provinces of China, based on the analysis of the current status of China's urban infrastructure development, using cluster analysis methods....
Taking Shandong province for example, this paper introduces the evaluation method and procedure of provincial famous brand, and then analyzes the main problems of evaluation mechanism of provincial famous brand product from the rationality of famous brand quantity, evaluating index, method and catalogue, and using cluster analysis to analyze the rationality of white wine famous brand of Shandong province...
The combination and scatter of the tourism resource directly determined the development and orientation of regional traveling ecosystem, and the new entity after the combination has more different features than the original one. This paper defined the annotation and extension of the concentrative region of tourism resources (CRTR), developed the niche theory of the CRTR. And a case study of Zhejiang...
