Abstract

The invention provides a decision-making method for determining a bridge maintenance sequence, and belongs to the technical field of bridge maintenance. According to the method, a comprehensive evaluation type with representativeness on a bridge maintenance score is extracted through principal component analysis, and then the evaluation type and an initial weight of an influence factor are obtained through transfer learning and a Delphi method; obtaining a difference value between the bridge maintenance score and the actual score; the evaluation type weight is optimized; the influence factor weight is optimized according to the evaluation type error; obtaining an updated bridge maintenance score; sorting the updated bridge maintenance scores by adopting a merge sorting method; and the bridge is maintained according to the bridge maintenance sequence. According to the method, initial weights of evaluation types and influence factors are obtained by adopting transfer learning and a Delphi method, the weights of the evaluation types are optimized, and the weights of the influence factors are optimized according to evaluation type errors; and the bridge maintenance scores are ranked after being recalculated, so that the accuracy of bridge maintenance is improved.

Description

technical field [0001] The invention relates to the technical field of bridge maintenance, in particular to a decision-making method for determining the order of bridge maintenance. Background technique [0002] At present, the bridge maintenance work in our country is simply repairing the bridges with existing problems, that is, it is in the stage of passive maintenance. Since the construction of infrastructure in our country takes up most of the financial budget, due to the limitation of national financial resources, the funds invested in bridge repair and maintenance are far from meeting the needs, so it is necessary to allocate limited funds reasonably. [0003] The ordering and optimization of bridge maintenance projects need to consider the priority of each project and the balance between regions. The current bridge maintenance sorting methods are commonly used in the following two ways. The first is the sorting among many optional maintenance schemes; the second is t...
