【摘要】 在流域防洪工程体系安全评价的指标体系及其等级标准的基础上,提出了用集对分析方法构造可变模糊集的相对差异度函数,进而建立流域防洪工程体系安全模糊综合评价的新方法(SPA—FCE)。结果表明,SPA—FCE计算过程直观、简便、通用性强、评价结果合理、精度高,可适用于已知等级评价标准的各种系统综合评价问题,有利于推动可变模糊集理论的进一步发展。更多还原

【Abstract】 Comprehensive security evaluation of valley flood control engineering systems can serve as an important basis for the security management of valley flood disaster.In order to develop quantitative comprehensive security evaluation model for valley flood control engineering systems,on the basis of security evaluation index system of valley flood control engineering and its grading criterion,a new method was presented to establish the relative diversity degree function of variable fuzzy set using set pair analysis method,which combined with fuzzy comprehensive evaluation can form a new model,namely the integrated model of set pair analysis and fuzzy comprehensive evaluation(namely SPA—FCE for short).The result shows that SPA—FCE is visual,simple and general,its result is reasonable and its computation precision is high.SPA—FCE can be applied to different comprehensive evaluation problems under the known grading evaluation criterion and can be of great advantage to develop the theory of variable fuzzy sets.更多还原
