摘要
针对海洋平台概念设计中经常遇到的复杂的方案优选问题 ,提出将多因素、多层次模糊优选理论引入平台的设计选型工作中 .采用三级模糊优选考虑了影响平台选型的各种因素 ;针对影响因素复杂、确定隶属函数主观因素较强的情况 ,成功引入因素的优先关系法来确定优选矩阵的隶属度 ,这样较好地减少了确定隶属函数的人为影响 .通过此优选模型成功地将影响平台设计选型的 1 3种主要因素和 8种平台设计型式进行了多级模糊综合优选决策 ,得到了比较理想的决策结果 ,为海洋平台设计选型提供了新的思路 .
Because of the difficulties met in conception design of offshore platform, a multi level and multi factor fuzzy optimization model has been used in optimum lectotype of offshore platforms. In order to decrease the subjective influences, the three level fuzzy optimization has been introduced to cover most of the effect factors, and the prior relation method has been used to determine the membership in comprehensive optimization and weighting. The method of fuzzy optimization has been successfully used to testify by an offshore platform, and very ideal results have been obtained. The multi level fuzzy optimization model is remarkable.
