Performability modelling

Provides a single-source reference covering all aspects of performability evaluation.

Introduces a new approach to assessing the performance and dependability of systems thus revealing system characteristics that cannot be uncovered separately by performance or reliability evaluation.

Explains how systems can operate partially in the presence of failures by discussing:

- Capacity of failure prone clusters of transaction processing systems.

- Network throughput when network nodes and links fail. IL

- Task completion times on degradable multiprocessor systems.

- A variety of modelling and evaluation techniques.

Features software tool descriptions to support performability evaluations - as well as an extensive bibliography.

Computer scientists and engineers will find this excellent overview compulsive reading as will postgraduates and researchers in computer science a
