Innovation Capacity

As evaluation factors of enterprise technology innovation capacity are very complicated, evaluation methods commonly used do not consider interrelationships between every capacity element, which results in subjectivity of evaluation results. Because non-parametric methods can be used to deal with evaluation problems with many input and output, this thesis proposes DEA evaluation idea and establish DEA evaluation module. Through practical case study, optimum value analysis of sample enterprise, returns to scale analysis and projection analysis, relatively efficient enterprises are identified and adjustment proposals are put forth for inefficient enterprises. Case study shows that: DEA evaluation method is an efficient method to evaluate enterprise technology innovation capacity.

AbstractIn order to protect the offshore environment and strengthen the comprehensive rectification of sewage outfalls, an evaluation method of regional sewage outfalls by combining the marine numerical simulation and comprehensive evaluation technology was constructed, considering the marine environmental capacity and the ecological impact of sewage discharge from outfalls on the marine eco-environment sensitive areas. Then the layout rationality of each outfall was evaluated and the discharge scale was optimized with a case study of existing sewage outfalls in Xiamen. The results show that, the comprehensive evaluation score of Yundang outfall was 3 points in 2025, evaluated as the outfall with irrational layout. In 2035, the comprehensive evaluation scores of Fenglin and Dalipu outfalls were 3 and 2 points respectively, evaluated as the outfall with irrational discharge scale. It is suggested to control the scale of expansion or increase the reclaimed water reuse rate in Jimei and Gaoqi Wastewater Treatment Plants. This method has enriched the evaluation system for layout optimization of sewage outfalls, providing scientific supports for comprehensive improvement of sewage outfalls and marine environmental management.

Environmental Carrying Capacity

In order to clarify the comprehensive operational capabilities of the airport and better plan the sustainable development mode of the airport, this paper studies the evaluation method of airport environmental carrying capacity. First, this paper proposes the concept of airport environmental carrying capacity by taking into account the complex characteristics of airports affected by multiple factors and then selects 16 representative evaluation indicators to construct an indicator system based on the Driving Force-Pressure-State-Response (DPSR) framework. Finally, the accelerated genetic algorithm-projection pursuit model is established to model a comprehensive evaluation index, which is used to calculate the airport environmental carrying capacity (AECC). The results of the case study show that the AECC of Guangzhou Baiyun International Airport (CAN) decreased year by year from 2008 to 2017, which is in line with the coordinated development level of CAN. By analysing the changing mechanism of AECC and indicators, we get 6 key influencing indicators that led to the continuous decline of AECC and put forward some political suggestions to improve the AECC.

Pair Analysis

In order to make a reasonable evaluation of highway traffic safety facilities, a comprehensive evaluation method based on set pair analysis was proposed. An evaluation system of freeway traffic safety facilities was established. Combined with relevant norms and standards, each indicator in the evaluation system was divided and a reasonable threshold has been set. Through the calculation of the connection degree of ‘identicalness, differentness and reverse’, the maximum connection degree criterion was used to judge the evaluation results of freeway traffic safety facilities. Finally a case study was conducted to verify the proposed evaluation method. The case study shows that the selected highway traffic safety facilities are at a good level and this method can provide scientific decision basis for highway traffic facility renovation.

Self-compacting concrete (SCC) has been widely used in engineering for improving the product quality and efficiency at the construction sites, enhancing the working conditions and the appearance of concrete. Workability is an important property of SCC. But none of a single method has been developed for evaluation workability of SCC efficiently. Aiming at the quality control of fresh SCC, a fuzzy comprehensive evaluation method for evaluating workability of SCC was put forward and a case study was done by measuring slump, slump flow, L-box ratio, J-ring flow, bleeding and sieve segregation of fresh SCC in the present paper. Evaluation results indicated that fuzzy comprehensive evaluation method can give a quantitative evaluation of workability of SCC and it is convenient to establish an expert system for controlling the quality of fresh SCC by using fuzzy comprehensive evaluation method.

Sustainable development is a hot issue under the current background of resources and environmental crises. In this paper, Liaocheng City's sustainable development level is evaluated by using fuzzy comprehensive evaluation method. It is concluded that Liaocheng City's sustainable development level turned out to be moderate. The constraints of Liaocheng City's sustainable development are sustainable development awareness isn't formed and some problems are serious. Trains of thought include: strengthen sustainable development concept's understanding, strengthen capacity-building of improving sustainable development level and solve sustainable development practices' current problems.

This paper proposes a comprehensive risk assessment index system for Smart Grid cyber security, including five first-level indicators such as entity and environment security, management security, data security, software security and communication security. Every indicator includes specific sub factors. The cyber security risks for Smart Grid are emphatically analysed. The paper integrates AHP with Fuzzy evaluation method, through which the weight of each layer and the risk assessment matrix are determined. Practical case study shows that cyber security level of the Smart Grid is good, but it needs improvement and reinforcement in organization system, data signature, data backup and intrusion detection system.
