    Constraint checking for business process management
    (Informatik 2009 – Im Focus das Leben, 2009) Runte, Wolfgang; El Kharbili, Marwane
    Compliance management tackles issues related to both modelling and enforcement of business constraints in enterprises. In the context of business process management, we propose and describe the use of constraint satisfaction problems as a formal mean for representing these business constraints. We propose a multi-level constraint satisfaction approach to handle different levels of abstraction in business process modelling. We elaborate on the modelling of compliance requirements using constraint satisfaction and discuss implications of this technique such as problem solving strategies. This work shows that a certain class of compliance problems which can be grounded to constraint satisfaction problems can be solved efficiently using the proposed approach.

    Formalizing Dependencies in Business Process Models Using Constraint Satisfaction
    (INFORMATIK 2010. Service Science – Neue Perspektiven für die Informatik. Band 2, 2010) Runte, Wolfgang
    Compliance management tackles issues related to both modelling and enforcement of business constraints in enterprises. In the context of business process management [Sch00], we propose and describe the use of constraint satisfaction problems [Dec03] as a formal mean for representing these dependencies [Run09, REK09]. To achieve this result, the notion of a finite system is formalized and the rules for sequential and parallel system composition are provided. The reciprocal interaction is captured by the protocol concept. Being part of a larger supersystem is shown not to be a property which can be attributed to the system itself but depends on the context of its interaction, namely whether its interactions determine its behavior or not. The result seems to be especially relevant in Information Systems and eCommerce, as it raises concerns about what end-to-end for example in a security context in a system theoretic sense really means. It also demonstrates the tight connection between our system and our function notion and thereby contributes to a better understanding, why approaches that rest mainly on the function notion struggle so much with networklike interacting systems and the necessary ”loose coupling” in the sense of a sensible interaction with only little information about the internal state of the other actors.

    Modelling and solving configuration problems on business processes using a multi-level constraint satisfaction approach
    (Business process, services – computing and intelligent service management, 2009) Runte, Wolfgang
    In this paper we present our ideas to apply constraint satisfaction on business processes. We propose a multi-level constraint satisfaction approach to handle different levels of abstraction in business process modelling.
