Abstract

The ability to correctly analyse the impact of changes to system designs is an important goal in software engineering. A framework for addressing this problem has been proposed in which logical descriptions are developed alongside traditional representations. While changes to the resulting design have been considered, no formal framework for design change has been offered.

This paper proposes such a framework using techniques from the field of belief revision. It is shown that under a particular strategy for belief revision, called a maxi-adjustment, design revisions can be modelled using standard revision operators.

As such, the paper also offers a new area of application for belief revision. Previous attempts to apply belief revision theory have suffered from the criticism that deduced information is held on to more strongly than the facts from which it is derived. This criticism does not apply to the present application because we are concerned with goal decomposition rather than reasoning from facts, and it makes sense that goals should be held onto more strongly than the decompositions designed to achieve them.
