Engineering geological hazard is one of the main factors that caused damage to the city gas network. The damage degree caused by engineering geological hazard which often happen in a short period is often much higher than that due to its long-term effects of corrosion, internal and external stress. In this paper, we have done a research on the capability of city gas network resists the engineering...

Given the inconsistent study scale and measure criteria about, no study on and unreliability and invalidity of the research methodology of residents' perceptions on tourism impacts in anterior studies in China, this paper, through interviews of domestic and foreign experts and case studies of...
Information integration develops toward semantic integration on the Semantic Web. Ontology facilitates the integration of heterogeneous data sources by resolving semantic heterogeneity among them. In this paper, we propose the system architecture of integrated information platform for digital city based on ontology, including three main layers: distributed heterogeneous data source layer, information...
Through empirical research on reforming of China agricultural economic growth way to reveal the factors determining agricultural economic restructuring. The article use the Cross Section data of china to analyses the factors determining agricultural economic restructuring, comparing the Cross Section data(from 1995 to 2004) of various provinces (cities, districts) of china, the results show that The...
This paper proposes a game-theoretic model for the government pricing in the air transportation industry of China. The interaction between the government and airlines and the competition among airlines have been considered. A two-stage non-cooperative Nash game is developed to model the government's and airlines' decisions. Equilibria of the game are computed by an iterative algorithm, and a numerical...

Based on the differential pricing theory, the social class of passengers and...
The vehicle routing problem (VRP) is an important problem occurring in many distribution systems, which is also defined as a family of different versions such as the capacitated vehicle routing problem (CVRP) and the vehicle routing problem with time windows (VRPTW). The ant colony optimization (ACO) is a metaheuristic for combinatorial optimization problems, and the max-min ant system (MMAS) is a...
A new method for consistency adjustment of fuzzy preference relations matrix in computer-mediated Decision Making Groups was advanced. This method is based on the definition of satisfaction consistency which comes out of two axioms (connexity and transitivity) advanced by Arrow. A new target matrix R was presented, as a result of iteration, the mediation matrix was provided with the satisfaction consistency...
The query interface integration is the key technology in realization of Deep Web information integration. However the bottleneck problem is the solution of differences and conflicts of query interfaces. TheThe most existed query interface integration work mainly focused on the conflict of attribute labels and attribute value, but there are many kinds of conflicts between interfaces because of the...
