Emergency logistics is one of the important measures to solve the unconventional sudden disaster. The research on the distribution design of emergency logistics project has an important supporting role for the whole emergency rescue system. Therefore, it is necessary to analyze and plan the emergency logistics project scientifically in order to better serve the emergency rescue system. In view of the defect that the current emergency logistics model cannot completely describe the whole emergency logistics process, this paper proposes a new emergency logistics distribution model by using GERT random network. From the perspective of system, this model fully considers the possible situation in the process of emergency material transportation and puts forward the corresponding countermeasures, so as to improve the transportation efficiency of rescue materials in the actual disaster relief activities to speed up disaster relief. Based on the properties of moment generating function and the calculation method of Mason formula, this paper fully considers the success probability, risk probability, delivery time, and other factors of the distribution route and puts forward the transshipment scheme of each logistics site to the disaster sites. After that, the effectiveness of GERT stochastic network in the process of emergency distribution is verified by an example of a logistics distribution route, which provides decision-making basis for relevant departments. Compared with the literature, this paper uses GERT network model to intuitively and clearly express the overall process of emergency material distribution, breaks through the thinking mode of simply choosing the distribution path in the distribution process, combines with the dynamic changes of the distribution environment, and comprehensively considers the timeliness and traffic capacity of emergency material distribution in sudden disasters, so as to provide reference for emergency management in complex and random situations for decision-making reference.

复杂环境下应急物流分布图的评估与评审技术

应急后勤保障是解决非常规突发性灾害的重要措施之一。应急物流项目分配设计的研究对整个应急救援系统具有重要的支撑作用。因此，有必要科学分析和规划应急后勤项目，以更好地服务于应急救援系统。针对目前的应急物流模型不能完全描述整个应急物流过程的缺陷，提出了一种利用GERT随机网络的新的应急物流分配模型。从系统的角度出发，该模型充分考虑了应急物资运输过程中可能出现的情况，并提出了相应的对策，从而在实际救灾活动中提高救援物资的运输效率，加快救灾工作。本文基于矩产生函数的性质和梅森公式的计算方法，充分考虑了配送路线的成功概率，风险概率，交货时间等因素，提出了各物流场对灾害的转运方案。网站。之后，以物流配送路径为例，验证了GERT随机网络在应急配送过程中的有效性，为相关部门的决策提供了依据。与文献相比，本文使用GERT网络模型直观，清晰地表达了应急物资发放的总体过程，
