“…Recent development of abductive constraint solvers such as A-system (Kakas, 2001), which is itself written in Sicstus Prolog, may point to ways of enhancing the ability of the Failure Manager to further localize the origins of constraint failure and to infer and rank suitable constraint revisions for the relevant originators, assisting their collaborative recovery. These aims share common ground with work on constrained workflow management, as in (Hwang, 2003) and (Wainer, 2003a) and (Wainer 2003b) who variously employ procedural constraints or standard logic programming integrity constraints but not CLP (FD). We also intend partly to reimplement our model in the multi-agent formalism Go!…”

It is shown how an enterprise portal, supporting a community of users discharging roles expressed as combinations of plans and constraints, can be usefully guided by a constraint processor. In particular, constraint logic programming on finite domains provides the users with useful insights regarding their possible work schedules. Constraints assist also in shaping the electronic artefacts created and transmitted by the users. The implementation is supported by mechanisms for assigning and updating roles and for assisting the search for remedies in the case of constraint failure 411

The abilty to continuously revise business practices is essential to organizations aiming at reducing their costs and increasing their revenues. Rapid and continuous changes to business processes result in less control over the executed activities. As a result, the ability of process designers to produce solid, well-validated work ‡ow models is limited. Work ‡ow management systems (WfMSs), serving as the main vehicle of business process execution, should recognize these risks and become more dynamic to allow the required business ‡exibility. In this paper, we propose a dynamic mechanism that allows backtracking and forward stepping at an instance level. This mechanism analyzes the feasibility of applying certain modi…cations to running instances and provides an e¢ cient algorithm that avoids redundant operation activation. We believe that this mechanism can bolster the ability of a business process management system to deal with unexpected situations and to resolve, in runtime, scenarios in which such resolution both is called for and does not violate any business process constraints. Throughout this paper, we use the paradigm of Web services to demonstrate the capabilities of the proposed mechanism.
