Based on the Rate-Variable Fundamental In-tree Modeling Method of the System Dynamics, this paper discusses a problem that how to apply the system dynamics assessment Method based on Level and Rate Variable System in a determined Assessment Index System. It gives a method to determine the Level Variable and Rate Variable System method in the Assessment Index System, and then utilizes Rate-Variable Fundamental In-tree Models depicting the Assessment Index System. Based on this, it applies the System Simulation Assessment on the Supply Chain Performance of the Aviation Weapon Equipment Manufacturing, analyses the feedback dynamic complexity affecting the performance improvement; put forward the relevant Management Countermeasures, which achieves the purpose of analyzing Supply Chain Performance effectively utilizing the System Science Method.

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.

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.

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.
