Embodiment 1
[0045] The purpose of this embodiment is to provide an optimal intervention simulation method for panic in crowd evacuation.
[0046] Such as figure 1 As shown, an optimal intervention simulation method for panic in crowd evacuation, including:
[0047]Step 1: Establish a random event-based emotional contagion model (SEEC) to analyze the process of crowd emotional contagion;
[0048] Step 2: Establish a Hawkes process-based intervention model (HIEC), which can adaptively adjust the intervention intensity according to changes in the intensity of crowd events;
[0049] Step 3: Propose a maximum rate of return problem, and use the Artificial Bee Colony Optimization Intervention Emotional Contagion Algorithm (IE-ABC) to obtain the optimal solution. According to the current individual collision-free speed, perform crowd evacuation simulation movement;
[0050] Step 4: According to the current emotional intervention measures, the optimal intervention simulation of panic in crowd e...
