基于历史数据矩阵的机场道面维护决策方法

Maintenance decision of airport pavement based on historical data matrix

针对现有的机场道面使用性能决策模型中存在主观信息与客观数据利用程度低、指标权重局限性较大和反馈的决策信息不充分等问题,提出基于历史数据矩阵的多维模糊决策模型。分析影响机场道面的主要性能指标,构建历史数据矩阵。基于历史数据矩阵完成对中心指标矩阵和模糊识别矩阵的扩充,给出基于历史数据的多维模糊决策模型的计算方法。算例分析表明:该模型提高了利用道面历史数据和专家知识经验的能力,可较好地给出道面综合性能的评价信息,以及与其他道面状况的相近程度,能比较客观地得到道面的性能状况,提供较为充分的维护决策信息。

In the existing decision model of airport pavement performance,there are some problems,such as low utilization of subjective and objective information,limitation of index weight,insufficient feedback decision information,etc.A multidimensional fuzzy decision model based on historical data matrix was proposed.The main performance indexes affecting the rigid pavement of the airport were selected and analyzed,and the historical data matrix was constructed.Based on the historical data matrix,the expansion of the central index matrix and the fuzzy recognition matrix was completed.The calculation method of multidimensional fuzzy decision model based on historical data was given.The analysis of an example shows that the model improves the ability to use the historical data of the pavement and the knowledge and experience of the experts.The evaluation information of the comprehensive performance of the pavement can be given well,and the degree of similarity to the situation of the pavement in other projects is also given.It can fully and accurately reflect the performance of the pavement and provide adequate maintenance decision information.
