The time for the first call to each method is not included in the average, so initialization time isn't a factor in the results.
平均值中不包括每种方法第一次调用的时间，因此初始化时间不是结果中的一个因素。

The simulation results show that system's average service time under this kind of optimization method is 20% shorter than other ways, it gets obvious optimization effect.
Moving averagemethod is one of time series forecasting method, if time series have no apparent tendency moving, using moving averagemethod can accurately reflect actual situation.
