This volume provides a companion to "Proof in VDM: a Practitioner's Guide". Using the proof theory presented in that volume, it examines a variety of realistic case studies which illustrate different aspects of the use of proof in formal development. Rather than concentrating on the construction of formal specifications, it devotes two chapters to validation using proof, describing how proofs in VDM can be constructed via installations of the PVS and Isabelle theorem provers. The book provides reference material for practitioners of formal methods who need to construct proofs, students requiring a detailed introduction to the practicalities of proof, and researchers interested in the role of theorem proving in formal development and relevant tool support.
