Abstract Model Repair
Given a Kripke structure M and CTL formula $\varphi$, where M does not satisfy $\varphi$, the problem of Model Repair is to obtain a new model M' such that M' satisfies $\varphi$. Moreover, the changes made to M to derive M' should be minimum with respect to all such M'. As in mo...

| description | Given a Kripke structure M and CTL formula $\varphi$, where M does not
satisfy $\varphi$, the problem of Model Repair is to obtain a new model M' such
that M' satisfies $\varphi$. Moreover, the changes made to M to derive M'
should be minimum with respect to all such M'. As in model checking, state
explosion can make it virtually impossible to carry out model repair on models
with infinite or even large state spaces. In this paper, we present a framework
for model repair that uses abstraction refinement to tackle state explosion.
Our framework aims to repair Kripke Structure models based on a Kripke Modal
Transition System abstraction and a 3-valued semantics for CTL. We introduce an
abstract-model-repair algorithm for which we prove soundness and
semi-completeness, and we study its complexity class. Moreover, a prototype
implementation is presented to illustrate the practical utility of
abstract-model-repair on an Automatic Door Opener system model and a model of
the Andrew File System 1 protocol. |
