As the urbanization in China accelerates, metropolitan regions are tending to change their spatial expansion mode from traditional satellite city mode to city cluster development strategy. Under this situation, the paper proposes the method and steps of evaluation for urban distribution network in city which takes the city cluster development strategy. The method takes city cluster as the unit of network planning and evaluation, firstly analyze the functional orientation and the land allocation of the target cluster for evaluation, then take other clusters with the similar function in other metropolis by analogy, finally a more instructive evaluation index system and evaluation standard will be obtained. The practical application in the medium voltage distribution network of Mazhai Industry Park in the city of Zhengzhou has proved that the method proposed is able to meet the demand of practical work in distribution network evaluation under new situation.

In order to identify weaknesses in distribution network planning alternatives, providing a scientific basis for grid investment decisions, effective and comprehensive evaluation is needed. According to the related principles and objectives, this paper establishes a comprehensive evaluation index system based on hierarchy. This system is guided by the long-term development strategy of China southern power grid, including six strategic layer indices as safety and reliability, economic efficiency, coordination and flexible, smart and green, controllable risk and social benefits. The meaning and classification of every index is listed in details. According to different technical characteristics of every index different fuzzy membership functions are structured. Furthermore, in accordance with the relevant guidelines and specifications, this paper gives specific values of the membership function parameters to achieve standardization of indexes of different dimensions, laying the foundation for a comprehensive assessment.

Purpose The purpose of this study is that on the basis of the competitive edge theory, source mechanism and evaluation approaches of industrial cluster competitiveness, combined with international trends in the automobile industry and the features of Chinese automobile industrial cluster development, an evaluation index system about cluster competitiveness of auto industry is built with comprehensive consideration of factors such as cluster development environment, external scale effect and internal competitiveness from the perspective of value chain of automobile industry. Design/methodology/approach An evaluation index system for automobile industrial cluster competitiveness was realized by integrating current strengths and future growth capacities with multidimensional, dynamic and comprehensive characteristics, which included 3 second-level, 10 third-level and 16 fourth-level indices. In the light of evaluation methods, a group intelligence optimization algorithm – (cuckoo search) – and traditional methods of complex decision-making system – analytic hierarchy process (AHP) – were combined to propose the cuckoo-AHP evaluation method. It was applied for the calculation and optimization of weight values in an automobile industrial cluster competitiveness evaluation index for the purpose of obtaining better scientific and more reliable results. Findings The research might further enrich the evaluation theory of automobile industrial cluster competitiveness and also can be useful for showing how traditional evaluation methods can be combined with intelligent algorithms to carry out better automobile industrial cluster competitiveness evaluations. In addition, studies of channels for kick-starting Chinese auto industrial cluster competitiveness are expected to provide references for how to enhance the cluster competitiveness of the Chinese automobile industry. Practical implications Changsha and Liuzhou, the Guangxi automobile industrial clusters as the two empirical analysis objects selected for this paper, are geographically adjacent to each other. The automobile industries of the two cities are local pillar industries with the strong support of the local government. Both clusters have their own advantages and weak points with different characteristics of cluster development, and they enjoy a representative significance amongst China’s numerous auto industrial clusters that are taking shape. Comparative analysis of both clusters serves as a good reference for the objective evaluation of the competitiveness of Chinese automobile clusters in terms of their real and practical developments and in respect of the success of reasonable scientific and industrial cluster policies. Originality/value Multidimensional, dynamic, integrated evaluation index systems are constructed around automobile industrial cluster competitiveness, which has taken into account developments in current strengths and future growth capacity. The cuckoo-AHP evaluation method has been formed by combining the traditional decision-making method known as AHP with a new meta-heuristic optimization algorithm called “cuckoo search”. Both have been used in evaluations of automobile industrial cluster competitiveness in Liuzhou and Changsha, which will be beneficial for enriching automobile industrial cluster competitiveness evaluation theory and new evaluation methods that will enable better evaluations of automobile industrial cluster competitiveness.

Rapid industrialization and urbanization in China have led to a rapid increase in the number of brownfields, however there is a lack of identification of the spatial extent of brownfields in cities and accurate assessment of brownfield redevelopment. Based on the relationship between brownfields and urban complex ecosystems, this paper defines brownfields in China and constructs a comprehensive evaluation index system including socio-economic and ecological subsystems. Using Wuhu City as empirical evidence, 19 brownfields were identified using remote sensing data and field surveys. Based on the detection of soil contaminants in brownfields, a fuzzy integrated evaluation method was used to suggest their redevelopment direction. It is found that the government’s planned land use types and the brownfield redevelopment evaluation results match to a large extent, but social, economic and ecological environmental factors should be more fully considered. At the same time, the identification and redevelopment of brownfield sites in the city as a whole need to be carried out by the government’s professional forces in order to obtain more effective and scientific conclusions.

AbstractBased on association rules, this article proposed a method for intelligent recommendation of power supply mode, which helps decision-makers in the selection of many schemes. Firstly, a history database which includes the forecasting models and correlative factors was first built and association rule mining was conducted; then combined with the correlative factors in the designated area, the criteria matching in the rules mined were carried out with CBR technique; finally automatic recommendation of the power supply modes was achieved under the given conditions. By application of an example, it is demonstrated that the proposed method can not only automatically analyze the applicability of power supply modes and the intrinsic relationship between correlative factors but also provide, to some extent, theoretical basis for selection of power supply modes and practical utility for urban distribution network planning.

Adaptation evaluation index system is established according to the influences brought by the distributed generations (DGs) interconnected with the distribution network. Evaluation indicators are proposed to reflect the operating conditions of distribution lines, switches and other important devices of distribution network. Combine Analytic Hierarchy Process (AHP) and Principal Component Analysis (PCA) method is used to determine the weights of the evaluation indicators. Whereby obtain the comprehensive evaluation results of distribution equipment adaptation to DGs integration. A study of a practical grid is made in the cases of the DGs centralized integration, decentralized integration, and without DGs. The simulated result shows that a large number of DGs connected with the distribution network would deteriorate a majority of the equipment operating indicators, especially to the indexes related to switches and protection devices. Meanwhile, when a distribution network is connected into the same capacity of DGs, the distribution equipment would show a better adaptation to DGs' decentralized integration.
