Abstract

In a renovation of urban rail transit (URT) signal systems, the renovation scheme runs through the whole process of the renovation, and it is necessary to solve the problem of the comparison and decision-making of the plan. Through sorting out the relevant results of renovations, the renovation methods are classified into three categories: repair as old, upgrade and replacement, and upgrade and compatibility. For the renovation scheme, the renovation scheme selection index system including 4 dimensions and 14 sub-dimensions is constructed. Furthermore, the renovation scheme selection auxiliary decision algorithm based on fuzzy multi-attribute decision is proposed. The results of the case study fit well with an existing project, which verifies the effectiveness of the method and reflects the multi-attribute characteristics of the signal system renovation scheme. The proposed method can provide quantitative decision support for signal system renovations.
