摘　　要：随着银行业务领域的拓展,与之对应支持的科技应用系统也越来越多,如何根据当前系统的使用情况,对系统未来性能进行预测,从而很好的指导各个应用系统的维护工作成为当前亟待解决的问题。通过引入可靠性关于时间t的指数分布,对计算机系统未来的可靠性进行预测,从而获得系统可用性、和平均故障间隔的预测值。With the development of the banking business, more and more supporting technological application systems are coming forth. Then how to predict the system＇s future performance based on its present employment situation, thereby to well-instruct the maintenance work of the application system becomes the top priority. Through the introduction of reliability index on time distribution, the computer system＇s future reliability is forecasted and the predictive value of system＇s availability and BTBF is obtained.
