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 VDM Europe, formed
in 1985 as an advisory board sponsored by the Commission of
the European Communities. The VDM Europe working group
consisted of researchers, software engineers, and
programmers, allinterested in promoting 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 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.
Volume 2 contains four introductory tutorials (on LARCH,
Refinement Calculus, VDM, and RAISE) and four advanced
tutorials (on ABEL, PROSPECTRA, The B Method, and The
