[Fax program] simulation DL : 0: 设计一个M/M/S/k排队系统模型，用C++进行仿真，计算一个新的服务请求在各个状态k下的阻塞率，绘制出到达率-阻塞率曲线(matlab)，并将理论值与仿真值进行比较。 M/M/S/k模型为服务请求到达间隔时间服从泊松分布、服务时间服从指数分布、系统有S个服务器、系统容量为k（有限个）的排队系统。如果一个服务请求到达排队系统时，系统内已有k个服务请求，那么这个服务请求就会被拒绝（即不为该服务请求安排服务器，也不会将其排入系统队列）。由于系统容量为k，有S个服务器，所以系统队列的长度为k-S。-The design of a M/M/S/k queuing system model, with C++ for simulation, calculation of a new service request in every state under the blocking rate k, the arrival rate of drawing- blocking probability curve (matlab), and the theoretical value and simulation values. M/M/S/k model for the service request arrival time to obey Poisson distribution, exponential distribution of service time, the system has S servers, the system capacity of k (finite) of the queuing system. If a service request arrival queuing system, the system has k service request, then the service request will be rejected (that is, do not arrange for the service request server, nor will its queue into the system). Since the system capacity for the k, there are S servers, so the length of the queue system kS.
