    Hi everyone:

    The following program simulates a M/M/1 queue system. i have some difficulties in changing the program to simulate a M/M/C queue with 3 servers. Can anyone help me to solve this problem?

    Thanks in advance for your help

    #include <stdio.h>      
    #include "smpl.h"       
    void main(void)
      real Ta = 200;        // Mean interarrival time (seconds)
      real Ts = 100;        // Mean service time
      real te = 1.0e6;      // Total simulation time
      int customer = 1;     // Customer id (always '1' for this simulation)
      int event;            // Event (1 = arrival, 2 = request, 3 = completion)
      int server;           // Handle for server facility
      // Initialize SMPL subsystem
      smpl(0, "M/M/1 Queue");
    // Initialize server facility (single server)
      server=facility("server", 3);
      // Schedule arrival event at time 0 to kick-off simulation
      schedule(1, 0.0, customer);
      // Loop while simulation time is less than te
      while (time() < te)
        // "Cause" the next event on the event list
        // Process the event
          case 1:  // *** Arrival
            schedule(2, 0.0, customer);
            schedule(1, expntl(Ta), customer);
          case 2:  // *** Request Server
            if (request(server, customer, 0) == 0)
              schedule(3, expntl(Ts), customer);
          case 3:  // *** Release server
            release(server, customer);
      // Output standard SMPL report
