China’s urbanization over the past thirty years has been the fastest in history and has led to significant challenges in balancing urbanization and energy use. As a result, this study proposed a comprehensive green urbanization assessment index system considering energy use and environment protection together. To be specific, principal component analysis was applied to eliminate redundant information, and a slacks-based measure model was used to evaluate urbanization efficiencies. Meanwhile, with super efficiency incorporated, the proposed model enabled to distinguish the DMU from DMUs with same efficiency value, further, a projection analysis was conducted to direct the improvement of the identified inefficient decision-making units (DMUs). Finally, the comprehensive green urbanization index system was applied to a western Chinese province (Sichuan Province) to demonstrate the effectiveness of the proposed models, from which it was found that the overall green urbanization efficiency in Sichuan province was 81.54%, due to an input distribution imbalance and low technical efficiency.

Assessment Index System

In China, many young and middle-aged rural residents move to urban areas each year. The rural elderly are left behind. The number of the rural left-behind elderly is increasing with urbanization, but it is unclear which indicators can be used to assess their health condition. The health risk assessment index system was developed to improve the health level of the rural left-behind elderly. A two-round web-based Delphi process was used to organize the recommendations from fifteen Chinese experts in geriatrics, health management, social psychology who participated in this study. Meaningfulness, importance, modifiability, and comprehensive value of the health risk assessment indicators in the index system were evaluated. The effective recovery rates of the two-round Delphi were 86.67% and 92.31%, respectively. The judgement coefficient and the authority coefficient were 0.87 and 0.82, respectively. The expert familiarity was 0.76. Ultimately, the health risk assessment index system for the rural left-behind elderly consisted of five first-level indicators, thirteen second-level indicators, and sixty-six third-level indicators. The final indicators can be used to evaluate the health of the rural left-behind elderly and provide the basis for additional health risk interventions.

Different Levels

The concrete assessment index of cheese dyeing enterprises’ cleaner production is filtered out by the classic Delphi method (Delphi) of expert evaluation. According to the characteristic of Analytic Hierarchy Process (AHP),we have identified the different levels. Finally, assessment index system was established and the weight of each index and standard value were also determined. The cleaner production level can be evaluated eventually more intuitively. So it can provide the technical support and guidance for cleaner production assessment of Cheese Dyeing Enterprises and realize a sustainable development of this kind of enterprises.

Mountain Tunnel

Risk management for safety in mountain tunnel construction is of great significance. However, existing research lags behind engineering applications. In this paper, the risk of mountain tunnel collapse is used as an example to illustrate a new assessment method based on case-based reasoning, advanced geological prediction, and rough set theory. First, the risk surroundings and risk factors involved in tunnel collapse are integrated and summarized, and a risk assessment index system is established for tunnel collapse. At the same time, because the dynamic response parameters obtained by the advanced geological prediction usually indicate a typical geological structure, sensitive response parameters are introduced in the assessment index system. Advanced risk assessment can be performed for tunnel sections at a certain distance ahead of the tunnel face. Second, the major risk surroundings and the advanced geological prediction results are analyzed for the tunnel under assessment. Cases with similar attribute characteristics are selected via comparison with previous cases. Attribute reduction and calculation of weights are subsequently performed for the risk surroundings and risk factors of similar cases based on the attribute significance theory of rough sets. Finally, index screening and objective weights are applied in the fuzzy comprehensive assessment model. The results of this paper can be used to improve the theoretical level and reliability of risk assessment in tunnel safety and serve as a reference for tunnel construction.

Firstly, the importance and necessity of automotive eco-design were introduced. And then, the limit standards, testing methods and weight coefficient of basic indexes in assessment index system were pointed out. A linear-type dimensionless automotive eco-design assessment calculation method of individual index was proposed. Finally, the automotive eco-design assessment results calculation method was illustrated.
