This volume contains the proceedings of the 8th Workshop on Hybrid S- tems: Computation and Control(HSCC2005)heldinZurich,Switzerlandduring March 9 11, 2005. The annual workshop on hybrid systems attracts researchers from academia and industry interested in modeling, analysis, and implemen- tion of dynamic and reactive systems involving both discrete and continuous - haviors. The previous workshops in the HSCC series were held in Berkeley, USA (1998),Nijmegen,TheNetherlands(1999),Pittsburgh,USA(2000),Rome,Italy (2001), Palo Alto, USA (2002), Prague, Czech Republic (2003), and Philad- phia, USA (2004). This year s HSCC was technically co-sponsored by the IEEE Control Systems Society. The program consisted of 3 invited talks and 40 regular papers selected from 91 regular submissions. The program covered topics such as tools for analysis and veri?cation, control and optimization, modeling, engineering applications, and emerging directions in programming language support and implementation. We would like to thank the Program Committee members and reviewers for anexcellentjobofevaluatingthesubmissionsandparticipatingintheonlineP- gram Committee discussions. Special thanks go to Markus P. J. Fromherz (Palo Alto Research Center, USA), Edward A. Lee (University of California, Berkeley, USA), and Pablo A. Parrilo (Massachusetts Institute of Technology, USA) for their participation as invited speakers. We are also grateful to the Steering C- mitteeforhelpfulguidanceandsupport.

Christophersen and Ernesto Wandeler, the Publicity Chairs (with the help of Urban M ader); M- tine D Emma and Monica Fricker for local arrangements; and Frank J. Chris- phersen for putting together the proceedings.
