Validating planning domain models using B-AMN

The validation of planning domain models is an important issue and can present problems. In this paper we describe ongoing work which attempts to overcome these problems through the construction of a B-AMN specication which models the domain. The B-Method utilises B-AMN, a state-based formal specication language with tool support provided by the B-Toolkit. We describe how this tool support provides facilities for both animation and proof, and we propose the use of the B-Method at an initial level of domain capture. The approach is illustrated using a simple transport domain, where a high-level model, which can be reasoned with, is produced. In addition, animation allows validation by users.
