考虑同群效应的志愿者与应急任务匹配方法

A method considering peer effect for matching volunteers with emergence tasks

针对传统上救援志愿者单向指派模型的不足,建立一个考虑同群效应的双边匹配新方法。首先,描述考虑同群效应的志愿者与应急任务匹配的关系;其次,将志愿者、应急任务和志愿者同群评价值转换成置信度信息;在此基础上,将双边评价的置信度信息作为证据,通过证据融合求出匹配的满意度;最后,构建基于志愿者、同群志愿者和任务三方证据的匹配融合模型,获得整体最优解。算例表明,用所建立的志愿者与任务匹配方法能实现双边满意度最大。

In order to overcome the defects of one-sided volunteers＇ assignment models,a novel two-sided matching method considering peer effects was developed. Firstly,the volunteers-emergence tasks matching problem with peer effect was described. Secondly,all the evaluation values of rescue volunteers,emergence tasks and peers of volunteers were transformed into belief degrees. On this basis, two-sided evaluation belief degrees were taken as pieces of evidence and the degrees of satisfaction of matching were got by evidence fusion. Finally,a matching fusion model based on tripartite evidence of volunteer,peer volunteers and task was built from the global perspective in order to obtain the best solution. An illustrative example was given to demonstrate that volunteers and emergence tasks can gain the greatest satisfaction by the proposed matching method.
