Particulate matter 2.5 (PM2.5) pollution has become one of the most urgent issues to be addressed in China. The anthropogenic reasons of PM2.5 formation have considered to be highly related to local economic development model, industrial structure, energy structure and fast urbanization. The aim of this study is to explore the quantitative relationship between PM2.5 and anthropogenic factors in China...
In order to effectively control the risk of software project and overcome the effect of lack data and human subjective factors in the traditional evaluation, the transformation of quantification and reduction of natural language is realized, so a new evaluation model is put forward. Based on the concepts of risk weight, expert trust, risk consequence and so on, we use the correlation coefficient to...
The complexity of LUCC (Land Use / Cover Change, LUCC) determines that it is important to conduct the study of LUCC using complex system theories, in particular by the establishment of a mathematical model for complex systems. In this paper, the LUCC model was built based on GIS technology, CA (cellular automata) and Agent technology. Firstly, Landsat TM data of 2000 and 2010 are used to obtain the...
Through using the ArcGIS software as the platform, and taking DEM analysis, raster calculation and spatial interpolation of spatial analysis technology as the core method, this paper selects Menghai County as the study area, combines with the Delphi method, analytic hierarchy process, fuzzy membership function, farmland Integrated Fertility Index ( IFI ) and other methods, to establish major factors...
This letter studies the joint relay selection (RS) and spectrum allocation (SA) problem for the multi-user and multi-relay (MUMR) cellular networks. Regarding the amount of spectrum resource that a relay is willing to contribute for a particular user as the cooperative strategy of the relay, the joint RS and SA problem can be formulated as a cooperative bargaining game. Since there exists a unique...
Proceed from economy theory, this paper selects the best treatment method of slopes based on minimum investment principle. In economic analysis, the most important one is to find failure probability of slopes. Traditional calculation method doesn't consider the fuzziness of mechanical parameters. However, the fuzziness exists objectively. In this paper, fuzzy technique is introduced and failure probability...
The performance of an automatic fingerprint authentication system relies heavily on the quality of fingerprint images. Besides, the effective evaluation and quality classification of fingerprint images is of paramount significance in the applicability research of fingerprint recognition algorithm. In this paper, an effective quality classification method for fingerprint image based on neural network...
Land is one of the important resources and material ensure mend for human being to survive and develop. The land resource is a fundamental element in the complex system of “population-resource-environment-development (PRED)”. By using ABM technology, based on Repast platform, establishes the decision-making model of the changes of land use type and classifies as three types of individual, company...
Circular economy is the main direction of the development of world economy, and now it is the economy developing pattern of our country. This paper describes the operation of green supply chain, and re-assesses the risk system of green supply chain, and then use Fuzzy-AHP comprehensive evaluation model to make an assessment for the Green Supply Chain Risk to provide a reliable basis and assurance...
Increasing the public satisfaction is becoming the key issue in government management practices. Meanwhile, since service has the characteristic of "process consumption", people's perceptions on the public service quality no longer simply depend on the service results, but more on the interactions between themselves and the service departments. The service interaction quality becomes one...
Aiming at the difficulty in selecting the maintenance mode for power plant equipment with ration, the fuzzy comprehensive evaluation method based on entropy weight and analytic hierarchy process (AHP) is suggested. It combines entropy weight with AHP for against the casualness and subjectivity in traditional method. With the method, the mode is divided into some layers composed of index factors, and...
This paper uses the multiple regression analysis and the structural equation modeling (SEM) to study the relationship between venture capital and supporting environment. The empirical analysis results show that, the corporation leading science technology environment (CLSTE) and the government supportive policies synthesis level (GSPSL) have direct effects on the development of VC; the development...
