PublicationImplications of customer value perceptions for the design of electricity efficiency services in times of smart meteringSmart meters are the backbone of modern electricity metering and an important enabler of reaching energy efficiency targets. The implementation of new metering infrastructure is, however, making little progress and is often focused on technical aspects only. Additionally, existing smart metering information systems do not yet exploit the possibilities to optimally support customers in their electricity savings activities. Knowing customer preferences is absolutely essential for the effectiveness of energy efficiency measures and, as a consequence, for realizing the economic value of smart metering technology. The presented research contributes to the field by identifying customer value perceptions concerning new smart meter services in the retail electricity market in Switzerland. Founded on a choice-based conjoint analysis with a data sample of more than 1500 respondents from three Swiss regions, five customer segments with different preferences are identified. With the exception of the comfort-oriented customer segment, the other four segments are comprised of customers who are willing (1) to pay for smart meter services and (2) to change their behavior to save electricity. Based on the identified customer value perceptions, implications for the design of smart meter-based energy efficiency services are elaborated.Type:Journal:Volume:Issue:

PublicationTheory-Driven Reverse Engineering of Organisations(Ges. für Informatik, 2015)Driven by the strong demand for reusable yet situational business solutions on the one side and thenecessity to provide a stable, reliant foundation that allows to adapt the supporting informationsystems in a systematic way on the other side, the need for a closer link between relevant theoriesand successful practices for the design of enterprise information systems becomes evident. Theaim of the reported research is to provide such a link by means of prescriptive guidelines for theclass of problems concerning the reverse engineering of organisations. The reverse engineering oforganisations aims at deriving at the ontological models of organisations, which build the basis forthe design and engineering of information systems supporting the business needs. An ontologicalmodel as used in the presented research is defined as the highest-level constructional model of anorganisation, which is fully independent of its implementation. The prescriptive guidelines forreverse engineering presented in this paper are derived from the ?-theory (the Greek letter ? ispronounced PSI, which stands for Performance in Social Interaction), the theory that underliesthe notion of Enterprise Ontology. This theory regards organisations as social systems and sees ITsystems as support for social actors in performing coordination-related activities and productionrelatedactivities. In this paper we focus specifically on recommendations based on the ?-theoryconcerning the coupling of two types of enterprise models in order to derive at ontological modelsof organisations. The first type of models are derived by applying the Design and EngineeringMethodology for Organisations (DEMO) and the second type of models are derived by applying theArchitecture of Integrated Information Systems (ARIS).Type:Journal:Volume:Issue:

PublicationAn Enterprise Ontology-Based Approach to Service Specification(IEEE, 2013-04-01)In recent years, the WSDL and UDDI standards arose as ad-hoc standards for the definition of service interfaces and serviceregistries. However, even together these standards do not provide enough basis for a service consumer to get a full understandingof the behavior of a service. In practice this often leads to a serious mismatch between the provider's intent and the consumer'sexpectations concerning the functionality of the corresponding service. Though additional standards have been proposed, a holisticview of what aspects of a service need to be specified is still lacking. This paper proposes a service specification framework, whichis based on a founded theory, the PSI-theory. The PSI-theory originates from the scientific fields of Language Philosophy and SystemicOntology. According to this theory, the operation of organizations is all about communication between and production by social actors.Based on the PSI-theory, a definition of the notion of ‘service' is given and a specification framework is derived. This framework canbe applied both for specifying human services, i.e. services executed by human beings, and IT services, i.e. services executed by ITsystems.

PublicationEnterprise ontology based development of information systems(Inderscience Enterprises, 2011-02-01)For the development of enterprise information systems, the utilisation of a suitable methodology is essential, providing necessary methods and techniques for modelling the business domain and for designing the supporting information systems. Several methodologies exist and are widely applied in practice nowadays, but most of them lack a theoretical foundation. In this paper, we demonstrate an information system development methodology based on the notions of enterprise ontology and business components, and explain it within the conceptual framework called the generic system development process. The methodology allows for reduction of complexity of domain models and for identification of stable business components.Type:Journal:Volume:Issue:

PublicationCurrent Trends in Modeling Inter-Organizational Cooperation(Emerald Group Publ., 2009)Purpose – Modern enterprises face a strong economical pressure to increase competitiveness, to operate on a global market, and to engage in alliances of several kinds. In order to meet the requirements and challenges of participating in such alliances, companies must be able to cooperate effectively and efficiently. The purpose of this paper is to provide an overview of some major directions in inter‐organizational cooperation. Design/methodology/approach – In order to cope with the challenges of inter‐organizational cooperation, to share innovative research issues and to facilitate profound discussions about them, the authors organized a series of workshops on Modeling Inter‐Organizational Systems (MIOS‐CIAO!) starting at the annual OTM Federated Conference and Continuing at the Annual CAiSE Conference. This paper summarizes the results of the workshops. Findings – This paper provides an overview of what has been established and what is going on regarding the cooperation of enterprises in networks. The focus has been on the modeling of cooperation, from the business level down to the implementation level. Practical implications – This overview is a useful source of knowledge for those who want to have a quick insight in the relevant aspects of cooperation, and in many well‐known modeling approaches and techniques. It is also an inspiring source for those who want to investigate yet unsolved or unsatisfactorily solved problems. Although developments, both in theory and in practice, will go on, no landslides are expected. Particularly for practice, the value of this report will therefore last for a considerable time. Originality/value – Several core notions in the area of inter‐organizational cooperation are clarified, such as collaboration, cooperation, enterprise network, choreography, and orchestration. The whole process of developing or investigating an enterprise network is covered.Type:Journal:Volume:Issue:

PublicationBasic notions regarding business processes and supporting information systems(Springer, 2005-08-01)In order to achieve and maintain an optimal fit between business processes (BPs) and business process support systems (BPSs), both need to be understood thoroughly and coherently. Moreover, to benefit fully from the potentials of modern information and communication technology (ICT), the deep structure that lies behind the surface structure of BPs should be understood. The Ψ-theory, which is only summarized in this paper, provides the basis for such an understanding of BPs and BPSs as well as for some other basic notions. In particular, the notions of design and engineering and of architecture and ontology will be addressed. The conclusion is that these notions can consistently and coherently be related to each other, on the said theoretical basis, such that the concurrent (re)design and (re)engineering of BPs and BPSs can be performed more effectively.Type:Journal:Volume:Issue:

PublicationEffects of Demand Charging and Photovoltaics on the GridDue to the integration of renewable energies, the electricity grid is confronted with new peak situations that are caused by the new power plants. Beside these threats new metering technologies combined with information systems enable new pricing options that were not affordable for retail customers before. This paper contributes to the field by combining demand charging incentives with a feed in tariff for photovoltaics. Demand charges are a broadly used pricing concept for large scale and industrial customers but are not used for retail customers yet. In a simulation we first of all show the impact of solar plants on the grid. Secondly, we simulate the shift in electricity demand caused by a demand charge for retail customers. Our simulation shows that the solar panels reduce the purchased quantity of electricity while leaving the maximum peak unchanged. This leads to reduced revenues for grid operators without changing the costs. This negative impact can be improved by the demand charge for retail customers.
