Abstract: In this paper, the traffic flow concealment measure and flow distribution model of the uncertain military trffic net under the condition of flow constrain are proposed. The new measure formula could resolve the problem of the old measure method. Then, six natures of the military traffic network are analyzed, i.e. the un-negative property, the extend property, symmetry property, the directionality of the received and sent road, the convertibility of the military traffic net and the probability of circulation flow. By combining the above new concealment measure formula and six natures of the military traffic network, the flow distribution model of the uncertain militray traffic net under the condition of folw constrain is proposed. At last, a numerical example is used to show the feasibility and effectiveness of the new concealment measure approach and flow distrbution model.

Key words: uncertain direction military trafiic net, traffic restriction, concealment, entropy measure
