使用C++实现电梯调度算法

电梯调度算法是一种优化电梯运行的算法，通常用于多层建筑物中的电梯调度。下面是使用C++实现电梯调度算法的示例代码。
#include <iostream>
#include <queue>
#include <vector>
using namespace std;

class Elevator {
public:
int current_floor;
int direction;
int capacity;
int max_floor;
vector<int> requests;

Elevator(int max_floor, int capacity) {
this->current_floor = 1;
this->direction = 1;
this->capacity = capacity;
this->max_floor = max_floor;
this->requests = vector<int>(max_floor + 1, 0);
}

void add_request(int floor) {
this->requests[floor] = 1;
}

bool is_full() {
int count = 0;
for (int i = 1; i <= max_floor; i++) {
if (requests[i] == 1) count++;
}
return count >= capacity;
}

bool has_request() {
for (int i = 1; i <= max_floor; i++) {
if (requests[i] == 1) return true;
}
return false;
}

void move() {
if (direction == 1) {
current_floor++;
} else {
current_floor--;
}
}

void serve_requests() {
while (has_request()) {
if (requests[current_floor] == 1) {
cout << "Stopping at floor " << current_floor << endl;
requests[current_floor] = 0;
}
move();
}
if (direction == 1) {
direction = -1;
} else {
direction = 1;
}
}
};

class ElevatorSystem {
public:
int num_elevators;
int max_floor;
int capacity;
vector<Elevator> elevators;

ElevatorSystem(int num_elevators, int max_floor, int capacity) {
this->num_elevators = num_elevators;
this->max_floor = max_floor;
this->capacity = capacity;
this->elevators = vector<Elevator>(num_elevators, Elevator(max_floor, capacity));
}

void add_request(int floor) {
int min_distance = max_floor;
int min_index = 0;
for (int i = 0; i < num_elevators; i++) {
int distance = abs(elevators[i].current_floor - floor);
if (distance < min_distance &amp;&amp; !elevators[i].is_full()) {
min_distance = distance;
min_index = i;
}
}
elevators[min_index].add_request(floor);
}

void run() {
while (true) {
for (int i = 0; i < num_elevators; i++) {
elevators[i].serve_requests();
}
}
}
};

int main() {
ElevatorSystem elevator_system(2, 10, 8);
elevator_system.add_request(3);
elevator_system.add_request(5);
elevator_system.add_request(7);
elevator_system.run();
return 0;
}

该代码中定义了Elevator类和ElevatorSystem类，其中Elevator类表示一个电梯，它有当前楼层、运行方向、容量、最大楼层数和请求列表等属性，以及添加请求、判断是否满载、判断是否有请求、运动和服务请求等方法。ElevatorSystem类表示整个电梯系统，它有电梯数量、最大楼层数、容量和电梯列表等属性，以及添加请求和运行等方法。
在main函数中，首先创建一个ElevatorSystem对象，然后添加请求，最后调用run方法运行电梯系统。
该代码实现了简单的电梯调度算法，当有新的请求时，它会选取距离最近且未满载的电梯来服务请求。每个电梯会持续服务请求直到请求列表为空，然后改变运行方向并等待新的请求。
