摘要/Abstract

摘要：

同时考虑随机性和模糊性的动态疲劳可靠性控制问题十分复杂，根据检测结果和失效准则的模糊性，借鉴最小平均费用率模型的原理，提出一种简单可行的近海石油平台动态疲劳可靠性模糊控制的新模型。该模型考虑到资金的时间效应以及平台失效所造成损失随时间的变化规律，将有关结论推广到平台系统，验证了检测结果和失效准则的模糊性对动态疲劳可靠性控制的影响。考虑模糊不确定性可以得到更为合理的结果。

Abstract:

It is very difficult to resolve the problem about the dynamic fatigue reliability control simultaneously considering randomness and fuzziness of offshore drilling platform. According to the fuzziness of inspection results and failure criterion, a new simple fuzzy model for the dynamic fatigue reliability control of offshore drilling platform was proposed on the basis of the minimum cost per unit operation time model. Fuzzy model reckons the time effects of the capital and the loss of the failure of offshore drilling platform with time. The conclusion can also be generalized to the platform system. An example illustrated the validation of the proposed method. The effect of fuzzy uncertainty is very important for getting the reasonable dynamic fatigue reliability control.

Key words: offshore drilling platform, dynamic fatigue reliability, failure criterion, fuzzy control model, inspection, time effect
