摘要
基于结构逻辑图的理论，提出了以下确界算子和上确界算子分别作为串联与并联系统可靠度的计算模型；形成了复杂工程系统可靠度的逻辑分析方法。在此基础上，应用多阶段决策算子法，成功地求解了工程系统可靠度的优化设计问题；给出了桁架结构优化的数值计算例题。
In this paper,based on the theory of structure logic paradigm,computational model ofsystem reliability is presented by using infimum operator and supremum operator corre-sponding concatenate and parallel systems respectively,which formed logical analysismethod for complex engineering system reliability. Employed this computational model,theoptimum design of engineering system reliability is solved successfully by using the multi-stage decision operator method.A numerical example computed of structure optimization oftruss is given in this paper.
