基于合作博弈的管道外腐蚀多层次灰色动态评价
Multi-level grey dynamic evaluation of external corrosion of pipelines based on cooperative game
摘要
Abstract
The external corrosion evaluation of the pipeline can provide a basis for the optimization of the pipeline inspection and maintenance program. Considering the complexity and uncertainty and timeliness of factors of external corrosion of buried pipelines, the grey relational analysis method was introduced to pipeline corrosion evaluation field, so as to propose a multi-level grey dynamic evaluation of external corrosion of pipelines based on cooperative game. Firstly, an evaluation index system of external corrosion of pipelines, in which the soil corrosion, external coating performance, cathodic protection system and stray current interference were included, was established. The subjective weights of the indexes obtained from expert qualitative analysis were quantified by applying improved analytic hierarchy process based on group decision-making. The objective weights of indexes were obtained by detecting real-time data information. After getting the two weights, the synthetic weight of each index was obtained by cooperative game. The dynamic multi-level grey evaluation was established which can be used to determining the risk grade of external corrosion of buried pipelines to be measured. The performance of the proposed method was tested on the practical example about corroded buried pipeline in a certain area. The effectiveness and reasonableness of the constructed model was validated.关键词
