Abstract:

The paper proposes a mathematical model of the random variable generator through establishing me distribution function by collecting data on business   spots. And the implementation code of the algorithm for the model is described in detail by using the MS C＋＋programming language. The computer testingg on the customer-flow data collected from bank services on business spots shows that the random variable generator is completely able to produce the random number sequence required and meets the technical needs in system simulation.
