This paper introduces the probability and imperilment of combustible gas explode under heat - environment , expounds the domestic and overseas research status quo on explosive characteristic of combustible gas under heat - environment , indicates the primary questions and direction of how to develop more research on that subject 摘要阐述了热环境下燃气爆炸发生的可能性以及危害性，介绍了国内外关于热环境下燃气爆炸特性的研究现状，指出了存在的主要问题和开展进一步研究的主要方向。
After the analysis of distribution network , a dynamic distribution network discrete model ( ddndm ) was presented based on the theory of the bi - level dynamic distribution network . furthermore , ant colony algorithm ( ac arithmetic ) , which is introduced in this dissertation because of the ability of resisting combination explosion to np - hard problem , now is applied in ddndm . then the ac arithmetic solve pattern , arithmetic steps and the instance result have been presented , and that the ac arithmetic applied in the ddndm to solve the np problem is appropriate 本文通过对分销网络分析,在已有的二级动态分销网络模型研究基础上,提出了动态分销网络离散模型,并且在基于meta图的供应链集成网络模型基础上对模型进行了优化,最后采用对于np完全问题具有抵御组合爆炸特性的蚂蚁算法求解此模型,给出了蚂蚁算法求解的模式、解如何通过赋权meta图构造和具体算法步骤,还给出了实例结果,通过结果表明本文提出的基于蚂蚁算法解决分销网络优化中出现的np难题,能够得到较好的效果。
