【摘要】 工程背景为航天器舱的布局优化设计问題,为此我们研究了多种具有实用性的布局优化算法,并依据这些算法得出了多种不同的布局设计方案。航天器舱是一个复杂的工程系统,在概念设计阶段,能否对这些布局设计方案做出客观评价将最终决定整个系统设计质量的优劣乃至其成敗,因此系统方案评价工作十分重要。基于此,对国內外目前常用的系统方案评价方法的理论及其特点进行了研究,归纳为如下几类:层次分析法、模糊评价法、灰色理论法、物元分析法、聚类分析法、价值工程法、神经网络法以及综合评价法等,并简要介绍了各种评价法在工程领域中的应用情况,并就目前尚有待深入研究的问题进行了探讨。更多还原

【Abstract】 The engineering background of this paper is the layout optimization design problem of an aircraft cabin. So several practical layout optimization algorithms have been developed, from which a variety of design schemes with different layout performances are got. Aircraft cabin is a complicated engineering system. At the stage of conceptual design, whether a correct and objective evaluation can be made on these design schemes will ultimately decide a good or bad system performance, even its success or failure. Therefore, evaluation of design schemes is a very important task. Based on these considerations, the theories and characteristics of some evaluation methods in common use at home and abroad are studied. These evaluation methods include analytic hierarchy process, fuzzy decision, gray system theory, matter-element analysis, cluster analysis, value engineering, neural network and synthetical evaluation methods. For each method, some engineering application examples are briefly introduced. At last, some problems that are yet to be studied are presented.更多还原
