New Energy

In order to achieve the target of that non-fossil energy accounted for 15% in 2020 and 20% in 2030, new energy has developed rapidly in recent years in our country. However, the rapid development of new energy has brought many problems, such as the wind power curtailment, photovoltaic power curtailment, the unbalanced development in different regions and the imperfect policy. Therefore, it is necessary to make a comprehensive evaluation of the development of new energy, as the basis for the policy formulation and planning of new energy. In this paper, according to the characteristics of the new energy development in China, a comprehensive assessment model of new energy development is constructed, a set of assessment index system is proposed, which of the quantitative and qualitative combination, including energy production, energy consumption and policy mechanism from, and combining the Analytic Hierarchy Process(AHP) method to determine the weight coefficient. Finally, new energy development in Jiangsu province is taken as an example, the comprehensive evaluation of new energy development situation in 2018 is given.

AbstractCoral reef islands provide precious living space and valuable ecological services for human beings, and its sustainability cannot be ignored under the pressure of human activities. Carrying capacity (CC) assessment has gradually become an important means to measure sustainability of islands. However, there is little comprehensive evaluation of the carrying capacity of coral reef islands, and traditional evaluation methods are difficult to express the social-ecological characteristics of coral reef islands. The present paper proposes a comprehensive assessment model for coral reef island carrying capacity (CORE-CC) which comprises dimensions of resources supply, environmental assimilative, ecosystem services, and socio-economic supporting. According to the characteristics of the coral reef islands, the core factors and indicators of each dimension are selected and the corresponding assessment index system of "pressure-support" is constructed. The assessment involves (1) identification of carrying dimensions and core factors, (2) pressure/support measurement and (3) assessment of carrying state. A case study is conducted in Zhaoshu Island of China, demonstrating the applicability of CORE-CC model and serving as a reference for adaptive management.

Cellular Concrete

The durability of lightweight cellular concrete (LCC) and the corresponding assessment method are studied in this paper to improve the utilization of LCC in subgrade construction engineering. The durability assessment method is established by combining the analytic hierarchy process (AHP) with fuzzy comprehensive evaluation (FCE). The main assessment processes are as follows. Firstly, based on the physical and mechanical properties of LCC, the influencing factors are selected in terms of preliminary design, construction technology, and operation and management after completion of construction. The grading standard of influencing factors is established as well. Secondly, a multilevel assessment model with targets level, criteria level, and indexes level is established. AHP determines the effective weight of the lower level relative to the upper level. The consistency check of the judgment matrix is conducted to prove the rationality of the distribution of influencing factors’ effect weight. Thirdly, the membership function which is suitable for each influencing factor is built to calculate the membership degree. Besides, the practicality and reliability of AHP combined with FCE are demonstrated through a practical engineering case, which is the third section of a highway in Guangdong Province, China.

With the rapid development of urbanization, the contradiction between traffic demand and traffic supply is becoming more and more prominent, leading to a series of traffic problems, which seriously hindered the urban development in the direction of green. This paper expounds the connotation of green transportation and set up an appropriate comprehensive evaluation index system. Then, analytic hierarchy process (AHP) and generalized function method are applied to evaluate green development in Changsha city traffic system, obtaining the degree of development on green transport.Finally, we analyze the problems existing in the current traffic and put forward the relevant suggestions for these problems.

Science assessment to air material suppliers is an effective measure that insures cost controlling and safety operating of an airline. Through analyzing the main factors of the air material suppliers, this paper constructs an assessment index system of the air material suppliers. The weights of assessment indexes is determined by means of the analytical hierarchy process (AHP). A assessment model of air material suppliers based on fuzzy comprehensive theory has also been set up. The model is validated through example. This prove that the method can give an overall comprehensive assessment level of the air material suppliers.

In the context of the energy revolution, integrated energy services have ushered in a period of opportunities for rapid development. To assess the demand of users of integrated energy services, we establish indexes of demand of integrated energy service users. We got the assessment model based on the analytic hierarchy process (AHP) and entropy weight method. The proposed assessment model is tested on 50 users, and K-means clustering algorithm is used to cluster users. The characteristics of the service requirements of each type are analysed.
