Digital computer systems play a'vital part in society's technological advancement in all fields of endeavour. When digital computer systems fail, they can have a significant impact on industrial, commercial and residential users. With the significant increasing dependence on the use of digital computer and microprocessor systems in society today the need for accurate reliability performance data and models of these systems is essential to mitigate the cost and impact of computer interruptions to society. This paper will present the statistical results (i.e., 10 year study period) of the reliability pe;formance characteristics of the University of Alberta s AMDAHL 470/V8 computer system. A Markov model based on the major historical failure modes of the computer systems performance will be presented. The quantitative results of the model will be discussed considering the benefits and limitations of the model.
