Abstract: Die Service-Bereitstellung in Service-Oriented-Computing-Umgebungen wird durch Service Level Agreements (SLA) beschrieben. Aktuelle SLA-Management-Ansätze konzentrieren sich auf bilaterale Service-Provider-/-Requester-Konstellationen, gehen jedoch nicht auf SLA-Management- Anforderungen von Composite Service Providern ein. Diese betreffen das SLA-Management mit Providern von Atomic Services, mit Requestern von Composite Services und deren Abstimmung aufeinander. Ein Composite SLA Management Ansatz muss den Anteil von (Atomic) SLAs beim SLA-Management von (Composite) SLAs berücksichtigen. Der COSMA-Ansatz erlaubt ein integriertes Management von Atomic und Composite SLAs während deren gesamten Lebenszyklus. Er ermöglicht die Abbildung der Abhängigkeiten und Beziehungen zwischen unterschiedlichenSLAs und damit eine Kontrolle, Steuerung und Optimierung der SLA-Management-Aktivitäten.

Abstract: This paper introduces the concept of the Logistics Service Map, a modular service construction system with an inherent catalog function. Specialized service providers, so called logistics integrators are to use this concept to integrate subsidiary service providers into logistics networks. The main purpose of the Service Map is to enable and to foster the development of atomic as well as composite logistics services used by the integrator to fulfill customers' requirements. After a brief presentation of the applied research methodology, the current progress of research is outlined and a draft of future research activities and discussion points is given.

Abstract: The development of enterprise-wide service-oriented architectures (SOA) is a complex task. In most cases, evolutionary approaches are used to deal with the arising complexity. However, most of the existing design methodologies and implementation strategies focus on more technical, service realization specific aspects. Challenges regarding the definition and the management of related service artifacts throughout the whole service lifecycle are neglected. Also the implementation of a lifecycle-encompassing information management infrastructure is not addressed adequately in research and industry. In this paper we introduce a common service management information model (coSIM) that builds a foundation for the management of services and service infrastructures during design-, run- , and change-time.

Abstract: A recurring task when managing logistics networks in which logistics companies jointly offer services is the comparison of logistics services based on their underlying processes. The comparison is necessary for the integration of processes, the selection of logistics providers and the evaluation of a company's performance. Due to a high diversity of logistics services and their properties as well as due to the high amount of services automated logistics service comparison is needed to support this task. This paper presents basic requirements and evaluates the state of the art with regard to these requirements. In addition, an initial solution approach providing a solid base for future work is outlined.

Abstract: The logistics industry is characterized by a high level of collaboration between logistics customers and providers. In fact, sophisticated, knowledge-intense business models such as 4th party logistics providers that are responsible for planning, coordination, and monitoring entire supply chains across logistics companies can be observed. However, integrated approaches for engineering and management of fourth party logistics are rather in its infancy. The Logistics Engineering and Management platform is a service-oriented approach for the development and management of long and mid-term logistics contracts. It serves as a collaboration platform and integrates services from different logistics providers. In this paper a core feature of the platform is presented, a service repository as a single point of truth coping with the complexity of miscellaneous service descriptions and models. Central idea behind this repository is the integration of different specialized service models and the construction of a comprehensive model, which supports direct implementation of services as concrete logistics tasks. In this article we present preliminary results of the service repository's development and realization and an outlook for future research.

Abstract: Many use cases in business process management rely on the identification of correspondences between process models. However, the sparse information in process models makes matching a fundamentally hard problem. Consequently, existing approaches yield a matching quality which is too low to be useful in practice. Therefore, we investigate incorporating user feedback to improve matching quality. To this end, we examine which information is suitable for feedback analysis. On this basis, we design an approach that performs matching in an iterative, mixed-initiative approach: we determine correspondences between two models automatically, let the user correct them, and analyze this input to adapt the matching algorithm. Then, we continue with matching the next two models, and so forth. This approach improves the matching quality, as showcased by a comparative evaluation. From this study, we also derive strategies on how to maximize the quality while limiting the additional effort required from the user.

Abstract: Service provisioning is largely built on agreements specifying the mutual responsibilities of service providers and their customers with respect to functional and non-functional parameters. However, the dynamics that result from the service-oriented computing paradigm in particular in composite services place new challenges onto the management of composite service level agreements which could not be achieved yet. This paper discusses the management of SLAs involved in composite services using the COSMA approach. After introducing the COSMA approach, the usage of COSMAdoc instances for negotiating SLAs in composite services is presented in detail.

Abstract: Sustainability issues are becoming more complex. Private companies respond to the new challenges with the pursuit of corporate social responsibility. One way to contribute to society and to deal with the increased pressure is by engaging in cross-sector partnerships with nonprofit organizations. But under which conditions are these partnerships successful? Using a multiple case research design we study the challenges in the process of creating sustainable value for supply chains through cross-sector partnerships between pharmaceutical companies and nonprofit organizations operating in developing countries. The chapter answers two research questions: (1) What are the challenges affecting the success of cross-sector partnerships to create sustainable value? (2) How can these challenges be addressed by Operations Management (OM)/Supply Chain Management (SCM) research?

Abstract: Das Ziel dieses Beitrags ist es, die wichtigsten theoretischen Entwicklungen zum Thema Führung und Kultur gegenüberzustellen und mit Hinblick auf die effektive Führung von multinationalen Teams in einer global vernetzten Welt zu diskutieren. Dabei liegt der Schwerpunkt des Beitrags vor allem auf sozial kognitiven Theorien: Zum einen, weil diese Theorien sehr erfolgreich den Einfluss von Diversität in Organisationen beschreiben, und zum anderen, weil diese Theorien in der interkulturellen Forschung sehr verbreitet sind. Abschließend werden die noch zu erforschenden Fragestellungen vorgestellt und Implikationen für die Führung multinationaler Teams abgeleitet.

Abstract: Im Beitrag wird aus verschiedenen Perspektiven der Frage nachgegangen, ob Führung weiblicher wird bzw. werden sollte. Dabei wird die Vorstellung von weiblich versus männlich (Geschlechtsrollen) mit der Vorstellung von Führung (Implizite Führungstheorien) und unterschiedlichem Führungsverhalten (z. B. transformational) verglichen. Die Autoren erläutern und nennen empirische Belege, warum effektive Führung sowohl weiblich-konnotierte (kommunale) als auch männlich-konnotierte (agentische) Verhaltensweisen umfasst, aber gerade weiblich-konnotierte (kommunale) Charakteristiken in Zeiten von (finanziellen) Krisen und schlechter Unternehmensleistung an Bedeutung gewinnen.
