Vehicle routing problem has been largely studied because of its application in logistic and supply chains management. A number of algorithms inspired by the foraging behaviors of ant colonies have recently been applied to solve vehicle routing problem and its variants. The behavior of ant colonies algorithms depends strongly on the values given to parameters. In most applications, parameter values...
In order to analyze the input-output structure in urban areas of China, this paper investigated the characteristic of fractal patterns of Zhejiang province using the model of fractal structure of the urban areas and that of C-D function. Labor, land, investment and energy are chosen as the input factors and GDP the output factor, and the dynamic similarity analysis is carried out on the relationship...
Urban thermal environment is a complicated nonlinear system, which is affected by the integration of various influencing factors inside the city. To explore the mechanism of urban heat island (UHI) effect formation in the city of Shanghai, China, decision tree is applied to establishing the quantitative relationships between urban thermal environment and its influencing factors, which reflect ecological...
This study validates that population structure is the key influencing factor and decides the decision making in the site selection of supermarket. Decision Making and Trial Evaluation Laboratory (DEMATEL) methodology is adopted to classify and sort order the influencing factors among the importance and priority orders of influencing factors in the complicated supermarket site selection system using...
Metro, as a most effective measure, play an important role to alleviate the traffic pressure, also is one of most important characteristics of the identity of city. According to the research result of European industrial association, from 2005 to 2015, globe metro market value increases 2.7% every year, especially focus on developing countries, facing this complexity, this paper tries through the...
