危险品运输网络在遭受恐怖袭击后单个节点的失效可能会引发网络级联失效现象。为解决该问题,构建一个危险品运输网络级联失效抗毁性模型。根据恐怖袭击条件,定义“正常”、“失效”和“暂停状态”3种节点状态,从“结果性”和“过程性”2个视角出发,提出网络抗毁性的评价测度。通过建立仿真场景,在不同节点的度、不同容量系数和不同规划方式下对危险品运输网络级联失效特性进行定量研究,结果证明了该级联失效抗毁性模型的科学有效性。
危險品運輸網絡在遭受恐怖襲擊後單箇節點的失效可能會引髮網絡級聯失效現象。為解決該問題,構建一箇危險品運輸網絡級聯失效抗燬性模型。根據恐怖襲擊條件,定義“正常”、“失效”和“暫停狀態”3種節點狀態,從“結果性”和“過程性”2箇視角齣髮,提齣網絡抗燬性的評價測度。通過建立倣真場景,在不同節點的度、不同容量繫數和不同規劃方式下對危險品運輸網絡級聯失效特性進行定量研究,結果證明瞭該級聯失效抗燬性模型的科學有效性。

Single node’s failure may cause cascading failure after hazardous materials transportation network is attacked by terrorist. Aiming at this problem, a model of cascading failure invulnerability for hazardous materials transportation network is established. Under the condition of the terrorist attack, it defines three kinds of node status which are“normal”,“failure”and“pause”, and from the perspective of“result”and“process”, the invulnerability indicators and their calculations are proposed. Then, it takes a quantificational research through different node degrees, different capacity coefficients and different planning modes by establishing simulation scene. The results show that the model is scientific and effective.
