      The Variety of Queuing Models
           Model A(M/M/1): Single-Channel 
               Queuing Model with Poisson Arrivals 
               and Exponential Service Times
           Model B(M/M/S): Multiple-Channel 
               Queuing Model
           Model C(M/D/1): Constant-Service-
               Time Model
           Little’s Law
