Abstract: Sometimes it is hard to predict the billing system device performance accurately and adjust process resource dynamically, the devices are overloaded under high business pressure and idle when there is no business. Aiming at this problem, this paper analyzes the relationship between business flow and system load, proposes a new modeling method of load model of a billing system, which is based on the tpmC equivalent of every single business process unit, through decomposing business flow of same device and researching the effect of every business flow. Experimental result shows that the error between load data and actual data of predicted system is less than 3%, this model is helpful to enhance the efficiency of system resource, and guarantees the stable operation of the system.
