About these proceedings
The proceedings of the fourth Vienna Development Method
Symposium, VDM '91, are published here in two volumes.
Previous VDM symposia were held in 1987 (LNCS 252), 1988
(LNCS 328), and 1990 (LNCS 428).
The VDM symposia have been organized by the VDM Europe,
formed in 1985 as an advisory board sponsored by the
Commission of the European Communities. The VDM Europe
working group consisted of reasearchers, software engineers,
and programmers, all interested in prommoting the industrial
usage of formal methods for software development. The fourth
VDM symposium presented not only VDM but also a large number
of other methods for formal software development.
Volume 1 contains the conference contributions. It has four
parts: contributions of invited speakers, papers, project
reports, and tools demonstration abstracts. The emphasis is
on methods and calculi for development, verification and
verification tools support, experiences from doing
developments, and the associated theoretical problems.
Volume2 contains four introductory tutorials (on LARCH,
Refinement Calculus, VDM, and RAISE) and four advanced
tutorials (on ABEL, PROSPECTRA, THE B Method, and The
Stack). They present a comprehensive account of the state of
