基于组合赋权-改进灰色关联法的架桥机配置评价

Evaluation of Bridge Erection Machine Configuration Based on Combined Weighting-Improved Grey Correlation Method

为选择最优铺架设备以保证复杂铺架工程的工期,构建架桥机关于工程适应性和效用性的指标评价体系,进而建立起基于组合赋权-改进灰色关联法的架桥机配置评价模型,通过适应性评价确定备选方案;采用模糊层次分析-CRITIC法对效用性指标进行主客观组合赋权,确保主客观信息的完整性,进而采用逼近理想解法的改进灰色关联投影法对备选方案进行效用性评价,提高评价准确性,最终确定最优设备方案。实例分析证明,该模型能为铺架工程选择架桥机提供指导。

In order to select the optimal bridge erection equipment to ensure the construction progress,the evaluation indicator system for the adaptability and utility of the bridge erection machine was established,and the evaluation model of the bridge erection machine configuration based on combined weighting-improved grey correlation method was built.The alternatives were determined through adaptive evaluation;the FAHP-CRITIC method was used to make the subjective and objective combination of utility indicators to ensure the integrity of subjective and objective information.And then Technique for Order of Preference by Similarity to Ideal Solution(TOPSIS)was used to improve the evaluation accuracy of grey relational projection method and determine the optimal equipment.Finally,an example analysis shows that the model can provide practical guidance for the selection of bridge erection machine.
