[Data structs] 救护车调度模拟系统 DL : 0: 用c语言设计实现一个用事件驱动的“救护车调度”离散模型，模拟120急救中心响应每个病人的呼救信号统一调度救护车运行的情况。我们对问题作适当简化，假设：某城市共有m个可能的呼救点(居民小区、工厂、学校、公司、机关、单位等)，分布着n所医院(包含在m个点中)，有k辆救护车分派在各医院待命，出现呼救病人时，由急救中心统一指派救护车接送至最近的医院救治。救护车完成一次接送任务后即消毒，并回原处继续待命。假定呼救者与急救中心、急救中心与救护车之间的通讯畅通无阻，也不考虑道路交通堵塞的影响。可以用m个顶点的无向网来表示该城市的各地点和道路。时间可以分钟为单位，路段长可表示为救护车行驶化费的分钟数。这里设m=10,n=3,k=2。并且令消毒时间为２分钟-language used to achieve a design using event-driven "ambulance dispatch" dispersion model to simulate 120 emergency response center each patient's distress signal unified dispatching ambulances running. We issue the appropriate simplified assumptions : m in a certain city a total of 000 points possible hue (residential quarters, factories, schools, companies, organizations, units, etc.), distributed by the hospital n (m included in the points), k ambulances were deployed in the various hospitals on standby there cries of the patients, from the first-aid center unified ambulance escort assigned to the nearest hospital for treatment. Ambulance completed a Shuttle mission after disinfection, and to continue the original standby. Assuming hue with the first-aid center, a medical
