This book constitutes the refereed proceedings of the 8th International Conference on Tools and Algorithms for the Construction and Analysis of Systems, TACAS 2002, held in Grenoble, France, in April 2002. The 29 revised full papers presented together with one invited paper and four tool papers were carefully reviewed and selected from 95 submissions. The papers are organized in topical sections on real-time and probabilistic systems, scheduling, miscellaneous, software verification, infinite-state and parametric systems, model checking: logics and algorithms, model checking and testing, partial-order and simulation techniques, and debugging with model checking.
