摘　　要：指出了结构整体性能实现的阶段性特征,明确了选型阶段是对结构整体性能进行规划、控制与优化等的关键环节,初步给出了从不同角度表征结构及其相关全系统、全寿命、全性能等客观需求与约束的结构选型性能模型。接着分析介绍了四种智能评价方法（即ES、FIS、ANN、ANNFIS法）,给出了集成智能评价支持系统的功能结构框图。在介绍了七种Mamdani模糊推理算法的基础上,将模糊综合评价与模糊推理方法结合,给出了一种兼有两者共同优点的多输入加权模糊推理与去模糊化算法及该算法用于性能评价的过程。最后,通过基于该算法的性能评价实例,给出了结构受力合理性性能评价的七条模糊规则及输入输出参数的评价等级标准、隶属函数及其加仅模糊推理的过程与结果。结果表明该方法能较好地表征与利用专家知识、经验与策略,能更好地满足结构选型多性能、多层次的性能评价需要,且评价过程与结果直观、有效。上述工作为表征、量化、控制与优化结构性能、恰当利用与改进各类结构、提高选型质量等奠定了基础。The stage characteristic of the whole structure performance is presented. And that the stage of form selection is the key point of the planning is pointed out, controlling, and optimizing to the structure performance, the intelligent form-selection model, which addressed the structure and its restrictions and requirements in the whole-system, whole-performance and whole-life cycle in a full view, is presented. Then four intelligent assessment methods (ES, FIS, ANN, ANNFIS etc.) were introduced and analyzed. And the function diagram of integrated intelligent assessment support system was also presented. Based on seven Mamdani Fuzzy function algorism, the fuzzy synthesizing evaluation and fuzzy function are combined, and a multi-input weighting fuzzy function and fuzzy-removing algorism and it's performance evaluation procedure are advanced, which include the advantages of both. At last, by instance of performance evaluation, 7 fuzzy rules of structure loading rationality assessment, the evaluation norm of input and output parameters, membership functions and it' s weighting fuzzy function and results are given. The results show that the method can fully use and express the experience and of experts, cater the requirement of performance evaluation of structure form selection of multi-performance, multi level, and the application and results are direct and effective. The work done pave the way for expressing, quantifying, controlling and optimizingof structure performance, using fully and improving various kinds of structure, and making the form-selection of structure more effective.
