- Abstract:
- The choice of maintenance project for existing railway tunnel lining crack is influenced by many fac.tors, including the investment costs, the natural environment and feasibility degree. In response to these fac.tors, this paper uses discernibility matrix heuristie reduction algorithm, expert evaluation method and multi.level gray comprehensive evaluation method to establish a comprehensive maintenance project for existing rail.way tunnel lining decision-making model. The model weights the Index layer objectively by using Matrix Re-duction Algorithm and weights the sub goals subjectively by using expert evaluation method, which ensures thescientific consideration of the weight, At the same time, the model decides the existing railway tunnel liningmaintenanee project comprehensively by using multi-level gray eomprehensive evaluation method to ensure thereliability of the results of decision-making. Examples of application show that the method can get the desiredquantitative results obtained, and it can be used more widely.
