    Industrial Services as a Research Discipline
    (Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 11, Nr. 4, 2016) Gitzel, Ralf; Schmitz, Björn; Fromm, Hansjörg; Isaksson, Alf; Setzer, Thomas
    Services in the industrial sector—commonly referred to as industrial services—are an important source of profit, differentiation and future growth for their providers. This sector includes industries such as heavy equipment manufacturing, energy production, chemical production and oil and gas. Despite its importance, neither the term industrial service(s) nor its concrete subareas are unambiguously defined. The goal of this paper is to motivate research which addresses the challenges currently faced in the industrial sector with regard to service. For this purpose, we review existing definitions of industrial services and identify the services in scope as well as the scientific disciplines that can contribute. The main part of the paper is a list of relevant current and future challenges which have been encountered by the authors during their daily practice.

    A Linked Data Based Messaging Architecture for the Web of Needs
    (Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 11, Nr. 3, 2016) Kleedorfer, Florian; Busch, Christina Maria; Huemer, Christian; Pichler, Christian
    Electronic marketplaces are built to resemble real marketplaces structurally. Consequently, they are centralized systems, walled gardens with an intrinsic tendency to lock merchants and clients in. We argue that this structure is not necessary on the Web and that all online marketplaces could merge into one global medium for exchange. In this paper, we propose an architecture for such a medium based on semantic Web standards, encompassing the functionalities of publishing an intention to buy or sell, finding transaction partners, and conducting transactions. We focus on the basic protocol layer and explain how messaging and linked data are combined in a novel way to realize a highly dynamic communication system.

    An Indexing Technique for Compliance Checking and Maintenance in Large Process and Rule Repositories
    (Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 11, Nr. 2, 2016) Rinderle-Ma, Stefanie; Kabicher-Fuchs, Sonja
    Business process compliance has become a crucial challenge for enterprises throughout different domains. However, little thought has been spent on the management and verification of compliance rules in large process repositories so far, even though several case studies show, that the amount of business processes can reach from a small set to hundreds of business processes being subject to several hundreds of compliance rules. In this paper we present activity-oriented indexing techniques for efficient compliance checking which are particularly applicable in process and rule repositories where no a-priori knowledge, \eg based on policies, is available. Different applications beyond compliance checking are discussed such as process similarity notions or maintenance issues. The effects of applying indexing on the effort for compliance checks are discussed along with further aspects such as maintenance of process model and compliance rule repositories. Finally, a case study from the higher education domain in Austria is provided. The presented techniques constitute a first step towards a cost- and effort-aware management of large business process and compliance rule repositories.

    A Conceptual Framework for Analysing Enterprise Engineering Methodologies
    (Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 11, Nr. 1, 2016) Albani, Antonia; Raber, David; Winter, Robert
    For the design and engineering of enterprises, several methodologies are available that successfully address certain aspects of design problems in enterprises or certain domains. In real-world design problems it is essential to choose the right means to reach the desired ends. Often it is not apparent which methodology is best chosen in order to reach desired ends. Additionally, real-world design problems often require several such methodologies to be combined because multiple aspects have to be covered and/or the problem combines characteristics of several domains. In order to allow for a systematical understanding and comparison of methodologies and for a facilitation of their composition (if necessary), we propose a general conceptual framework. The framework allows analysing the essential concepts and constituent parts of enterprise engineering methodologies. The resulting analysis supports decisions making concerning which methodology or which combinations of methodologies to apply to the given design problem. To demonstrate its usefulness, we rst analyse the concepts and building blocks of two design and engineering methodologies on that basis. Second, we show how these two methodologies, which are based on very similar concepts—as resulted from the analysis by applying the conceptual framework—can be combined in order to derive at a complete solution for a given design problem.
