System Assistance in Structured Domain Model Development

Abstract

In this paper, we introduce a domain modeling tool that supports users in the incremental and modular development of verified models of planning domains. It relies on a logic-based concept for systematic domain model construction that provides well-defined, safe operations for the union, extension, and refinement of already existing models. The system is equiped with a deductive component. It automatically performs the proofs necessary to guarantee both the consistency of single models and the safety of operations on models. By means of detailed examples, it is shown how the system has been used for the structured development of a model for a complex, safety-critical planning domain. 1 Introduction As soon as we aim at using planning systems in the context of realistic applications, the task of generating the underlying domain model becomes increasingly crucial. It is not only difficult to overlook the great amount of object types, relations, and actions involved when specifying such...
