matlab中双电梯仿真代码

以下是一个简单的 MATLAB 双电梯仿真代码，你可以根据自己的需要进行修改和扩展：

%% 双电梯仿真代码

% 参数设定
floors = 10;            % 楼层数
people = 20;            % 乘客数
elevator_capacity = 8;  % 电梯容量
steps_per_floor = 15;   % 每层楼所需时间
elevator_speed = 3;     % 电梯速度
elevator_delay = 2;     % 电梯延迟时间

% 初始化电梯状态

elevator2 = struct('position', 1, 'direction', 1, 'queue', [], 'timer', 0, 'occupants', []);

% 初始化乘客状态
people_waiting = struct('floor', [], 'destination', [], 'timer', []);

% 初始化计时器
time = 0;

% 生成随机乘客

    people_waiting(i).floor = randi(floors);
    people_waiting(i).destination = randi(floors);

注意，这只是一个简单的双电梯仿真代码，还有很多需要完善的地方，例如电梯的调度算法、乘客的等待策略、电梯内部的行为等。如果需要更加精细的模拟，请根据实际需要进行修改和扩展。
