【摘要】 对于某些容错计算系统，由于成功与故障之间没有明确的界限，用传统的可靠性指标难以准确地评价其容错性能，为此一些学者提出了若干与性能相关的可靠性指标。本文将这些指标概括成三类（即基于瞬时性能的指标、基于累积收益的指标和率模可靠性指标）加以介绍，并简要介绍了它们的求解方法。更多还原

【Abstract】 For computing systems in which there is no distinct difference between success and failure states, it is difficult to properly evaluate their fault-tolerant characteristics. For this reason, many pelformance-related reliability measures have been proposed. In this paper these measures, classified into three categories (i. e. measures based on instantaneous performances, measures based on cumulated performances, and profust reliability measures), are introduced. Their solution methods are also briefly given here.更多还原
