Multi-objective comprehensive evaluation method is a new evaluation method which analysis on the sustainable development. This article is evaluating the present situation of the sustainable development of China's power source structure through this method, view to the future development. We select 7 indicators in order to reflect the economic effects, environmental effects and power production levels, and describe the sustainability degree, the development degree and the coordination degree from 2000 to 2007 in China. The research indicated that although the China's power source structure is being far away from the unsustainable critical point slowly, slowly approaches to the target point, but the way deviated from the path of the development of optimal path.

Comprehensive Evaluation Method

This paper adopts the analysis method of big data to conduct an in-depth analysis and research on the sustainable development mechanism of enterprises, firstly, combing the content and methods of enterprise business performance evaluation, defining enterprise sustainable development, and exploring the integration of enterprise sustainable development and enterprise business performance evaluation by specifically analyzing from different perspectives. Then, we analyze the industry in which the enterprise is located, its business situation, and strategy, and after analyzing the current business performance evaluation system of the enterprise, we point out its problems. The current performance evaluation system is incomplete, focuses only on economic benefits, is not long term, and does not consider the company’s strategy and stakeholders’ needs, which affects its importance and feasibility. Then, the above analysis is integrated to build a performance evaluation system consisting of four dimensions, namely, economic dimension, scientific research and innovation dimension, social dimension, and ecological dimension, from the perspective of sustainable development, and a total of 29 indicators are selected. Then, the two research tools of first value method and fuzzy comprehensive evaluation method were combined, based on the panel data of enterprises from 2016 to 2020; the first value method was used to get the weights of each indicator in the business performance evaluation system. The fuzzy comprehensive evaluation method was used to get a comprehensive evaluation score of enterprise’s business performance in 2019, and then the evaluation results were analyzed in detail and suggestions were made, which confirms that enterprises are based on the sustainable development perspective. The evaluation of business performance is necessary and important. Finally, we propose supporting safeguards, such as establishing a performance evaluation team and a monitoring mechanism, dynamically improving the enterprise performance evaluation system, establishing a sustainable corporate culture, preparing and publishing a sustainable development report, and accelerating the information construction of performance evaluation.

The construction project bidding is a feasible method in engineering transactions and the main competition form of the construction activities under the conditions of the market economy. The bid assessment is an important link of bidding, and whether bid evaluation method is scientific or not, is directly related to the success of the tender. In the engineering construction field, at present the current commonly used evaluation methods are the comprehensive evaluation method and the lowest bidding price evaluation method. Based on fuzzy set theory and multi-objective people decision theory, we introduce fuzzy multi-objective people decision-making evaluation methods. And conducting research to put forward the evaluation index and weight method to determine the bidding decision model. Finally we apply it to actual case to make out the more standardized and scientific bidding evaluation method.

The choice of evaluating indicator has a most important influence on the performance analysis and optimization of Organic Rankine-cycle (ORC) system. In this paper, the net output power of unit mass of exhaust gas (), the cycle exergy efficiency (), the total waste heat emissions () and the product of exchanger's area and total heat transfer coefficient () are selected as the four key indicators which can reflect the characteristics of ORC system. And then, a comprehensive evaluating indicator of ORC system performance () is obtained according to the theory of multi-objective optimization. Further, a comprehensive evaluation method of ORC system performance based on the multi-objective optimization is put forward in this paper. After that, this method is used to optimize the evaporation temperature which is considered as a key parameter of ORC system performance. According to researches, the results gained by using a single-objective optimization method with only one performance parameter as the indicator, cannot often take a global view of the ORC system performance and sometimes may lead to a deviation. Researches also show that increases firstly and then decreases with the increment of the evaporation temperature, and there exists a value of evaporation temperature to maximize . Through analysis and researches, it can be found that the comprehensive evaluation method of ORC system performance based on the multi-objective optimization provided in this paper gives a synthetic consideration to the requirements from high-efficiency, economy, thermodynamic perfection and environment protection. Moreover, by using this method, the ORC power generation system may be more likely to achieve the best comprehensive performance.

Development Level

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.

Patent Strategy

The implemented performance of enterprise’s patent strategy is an important component to measure its comprehensive benefits. It is of strategic significance for an enterprise to evaluate objectively its implemented performance of patent strategy. From the perspective of sustainable development, according to the 4 aspects of creation, application, protection and management of patent, the essay constitutes preliminarily a comprehensive evaluation index system of the implemented performance of enterprise’s patent strategy which is composed of a set of 21 indexes on the basis of an amount of domestic and foreign literature survey, case study and expert consultation, and analyzes the evaluation model and method of implemented performance of enterprise’s patent strategy with the fuzzy comprehensive evaluation and through a real case. The essay thinks the constitution of evaluation index system should obey a series of basic principles of objectivity, systematization, science and conciseness and the evaluation in essence is multi-object, multi-factor and multi-layer. Therefore, it is effective and feasible to select the Fuzzy Comprehensive Evaluation method.
