Reliability and Maintainability Considerations in Computer Performance Evaluation

This paper describes the application of R&M concepts to computer performance evaluation. The relevance of reliability to maintenance cost of computer system is established. Although a simple reliability model is used, one can use more complex models. The mathematical model for maintenance cost analysis must be tailored for individual cases, depending upon the maintenance philosophy of the organization. The computer performance analysis from maintenance view points should examine software reliability and recovery procedures, which are relatively difficult in distributed processing.
