摘要: 为提高岸边集装箱起重机(岸桥)金属结构安全评价结果的准确性和可靠性,建立岸桥金属结构安全评价指标体系和评价标准;采用层次分析法(AHP)和信息熵法分别计算评价指标的主客观权重,提出改进的博弈论组合赋权法(ICWGT),并运用ICWGT集结主客观权重;结合改进的可变模糊集(IVFS)评价方法,提出ICWGT-IVFS多级安全评价模型,并以实际算例验证该模型的科学性和有效性。结果表明:ICWGT能克服组合权重系数为负数的不足;ICWGT-IVFS模型能避免岸桥金属结构指标评价标准与系统综合评价标准的不一致性,有助于提高岸桥金属结构安全评价的准确性。

Abstract: In order to increase the accuracy and reliability of the safety assessment results of quayside container crane metal structure, an evaluation index system and evaluation criteria were established for metal structure of quayside container crane. Subjective and objective weights of the indexes were determined by analytic hierarchy process (AHP) and entropy methods. An improved CWGT method (ICWGT) was worked out, and the combination weights were integrated by the ICWGT. On the basis of an improved VFS (IVFS), an ICWGT-IVFS multi-level evaluation model was built. A practical example was given to verify the effectiveness of the model. The results show that ICWGT can overcome the drawback of negative weight coefficient, and that the ICWGT-IVFS model can avoid the inconsistencies between indicator standard and system criterion of quayside container crane metal structure, which is helpful in improving the accuracy of metal structure safety evaluation of quayside container crane.

Key words: quayside container crane, metal structure, improved variable fuzzy sets (IVFS), safety assessment, combination weights, improved combination weighting model of game theory (ICWGT)
