Weight calculation method for bridge technical condition indexes

The invention discloses a bridge technical condition index weight calculation method, which comprises the following steps of: firstly, determining a subjective weight of a bridge technical condition index by utilizing an uncertain analytic hierarchy process, then determining an objective weight of the bridge technical condition index by utilizing an entropy weight method, establishing a game theory model according to the subjective weight and the objective weight, and calculating the weight of the bridge technical condition index. Determining the optimal comprehensive weight of each layer of indexes relative to the upper layer of indexes; subjective and objective factors can be well considered, the subjective and objective factors compete with each other and are coordinated, the calculation principle is clear, and the process is simple. 本发明公开了一种桥梁技术状况指标权重计算方法，该方法首先利用不确定型层次分析法确定桥梁技术状况指标的主观权重，然后利用熵权法确定桥梁技术状况指标的客观权重，根据主、客观权重，建立博弈论模型，确定每层指标相对于上层指标的最优综合权重；能够很好地兼顾主、客观因素，使二者既相互竞争又协调一致，计算原理清晰、流程简单。
