非定向军事路网交通流隐蔽性测度及分配模型

为了解决原有军事路网隐蔽性测度模型中存在的不同运量在相同路况下隐蔽性测度值相等的悖论, 以及路网定向性导致分配非最优两方面缺陷, 本文在对隐蔽性测度方法进行修正以及对非定向军 事路网三方面性质(始点终点相连路段的定向性、路网的可转换性、中点相连路段的后定向性) 详细分析的基础上,提出了一个基于隐蔽性测度修正方法的非定向军事路网交通流分配模型, 并针对模型在计算过程中可能出现的循环流现象提出了逐步去环的解决方法.最后,通过算例证 实了非定向路网三方面性质及计算中可能存在的循环流现象,计算过程和结果充分说明新模型的可行性与实用性.

Traffic Flow Hidden Measure and Assignment Model for the Uncertain Direction Military Traffic Network

We first revise the hidden measure method and analyze the three natures of the uncertain direction military traffic network such as the direction determinacy of the beginning and end points, the convertibility of the traffic network, and the direction after-determinacy of the center points. Then, we derive a traffic flow hidden measure and assignment model for the uncertain direction military traffic network, which could make up for two deficiencies of the old models, i.e., the same concealment value about the different flows even in the same conditions and the direction determinacy hypothesis of the whole military traffic network. Next, we propose a subsets algorithm to avoid the circle flow, which could appear during the computational process of the new model. At last, the above natures and circle flow phenomenon are proved by an example, in which the feasibility and the usability of the new model and method are also reflected.
