摘要
震区应急物流设施容易被余震、泥石流等不确定因素破坏从而失效,所以震后应急物资配送应该考虑设施防护。综合考虑震后应急路网部分损毁、多方式配送、时间窗限制、部分设施被破坏、应急设施保护资源有限等特性,构建一个关键设施防护情景下震后应急物资配送开放式定位-路径问题的"防护-破坏-优化"三层主从对策模型,并根据模型特点设计一种免疫遗传算法予以求解。最后,采用汶川地震之后第一天的应急物资配送案例验证本文方法的可行性与有效性。
Emergency logistics facilities ties, e.g. strong aftershock, and mud - rock in earthquake areas can easily be destroyed by many uncertain- flow. Relief distribution shall consider facilities protection in the post -earthquake. By considering partial damage of emergency network, multi - model distribution, time win- dow constraints, partial damaged facilities, and limited protection resources, a tri -level hierarchical decision model of "protection - destroying - optimization" is proposed for the open location - routing problem of relief distribution under protection of critical facilities. An immune genetic algorithm is put forward to solve the mod- el. Finally, both the feasibility and effectiveness of the model and the algorithm have been demonstrated by re- lief distribution examples during the first day after the Wenchuan earthquake occurred.
