This book introduces the use of the distinct element method (DEM) in modeling crowd behavior and simulating evacuation processes. Focusing on the mathematical computation of the uncertain behavior of evacuees, which is switching action behavior, it subsequently reproduces the crowd evacuation process under several conjectural scenarios using a DEM-based multi-agent model that has been modified by introducing the switching action behavior. The proposed switching action behavior model describes a person who has to change his/her destination due to the limited space capacity of the designated evacuation area. The change in the destination of a person is determined according to the motion of other individuals in the perception domain during the defined switching action time. The switching action time is formulated in the so-called switching action function, which is described by a convolution integral of the input and unit response functions. The newly developed switching action model is then validated using sensitivity analysis in which the primary focus is the crowd motion and flow of switching action behavior.
商品描述(中文翻譯)
本書介紹了在模擬人群行為和撤離過程中使用獨特元素法(DEM)。重點在於對撤離者不確定行為的數學計算,這種行為是切換行動行為,隨後利用基於DEM的多代理模型重現了在幾個假設情境下的人群撤離過程,該模型通過引入切換行動行為進行了修改。所提出的切換行動行為模型描述了一個人因指定撤離區域的空間容量有限而必須改變其目的地。個體的目的地變更是根據在定義的切換行動時間內,其他個體在感知域中的運動來決定的。切換行動時間是通過所謂的切換行動函數來公式化的,該函數由輸入和單位響應函數的卷積積分描述。然後,通過敏感性分析驗證新開發的切換行動模型,主要關注人群運動和切換行動行為的流動。
