【摘要】：为了系统、客观地评估海洋平台的健康状况,将传统的层次分析法与模糊集理论相结合,对某在役海洋平台的结构健康状况进行评价,依据其结构特点创建了海洋平台评价指标体系并构造出相互关联指标之间的模糊判断矩阵,由此求出各指标权重,然后通过模糊综合评判计算出海洋平台健康状况分值,参照评语集得出海洋平台的状态评价等级。最后结合实例说明评判结果与实际情况相符,验证了该评估方法具有较强的可行性与合理性,方法计算简单、使用方便,具有推广价值。
[Abstract]:In order to systematically and objectively evaluate the health status of offshore platforms, the traditional AHP and fuzzy set theory are combined to evaluate the structural health of an existing offshore platform. According to its structural characteristics, the evaluation index system of offshore platform is established and the fuzzy judgment matrix between interrelated indexes is constructed, and then the weights of each index are calculated, and then the health status score of offshore platform is calculated by fuzzy comprehensive evaluation. The evaluation level of offshore platform status is obtained by reference to the evaluation set. Finally, an example is given to show that the evaluation results are consistent with the actual situation, and the feasibility and rationality of the evaluation method are verified. The method is simple in calculation, convenient in use and worth popularizing.
