Examples
- Based on the system engineering theory , and through detailed analysis of economic techniques of the engineering work plan examples of the common used long span steel truss structures , utilizing the sequenced layer analysis , the current paper will establish the long span engineering work plan index system . also by the fuzzy mathematical principles , it builds multi - layer fuzzy complex mathematics judgment and calculate the weight coefficient of each index by application of fuzzy power duality method ; and based upon the experts investigation method builds each index judgment matrix . finally applying the current popular update system tool - power builder 8 . 0 developed the " optimization system of ( construction ) fuzzy work plan " to solve and carry out the multi - layered fuzzy combination judgment ; then step on the analysis and research on the reliability of the optimal solution for further achievement of the final objective of the fuzzy optimization in selecting the construction work plan of long - span steel truss realization
本文以系统工程学的理论为基础，通过工程实例对常用大跨度钢桁架结构施工方案进行详细的技术经济分析，运用层次分析法建立起大跨度钢桁架结构施工方案的指标体系，利用模糊数学原理建立了多层次模糊综合评判数学模型，采用模糊权重二元对比法计算出各指标的权重系数，并采用专家调查法建立各指标的评判矩阵，利用目前最流行的工具系统- powerbuilder8 . 0编制了《建筑施工方案模糊优选系统》求解计算，进行多层次模糊综合评判；调整权重和隶属度，对数学模型最优解的可靠性作了进一步的分析和研究，从而达到模糊优化选择大跨度钢桁架结构施工方案的最终目的。
