- ZeitschriftenartikelEngineering Coordination(KI - Künstliche Intelligenz: Vol. 26, No. 1, 2012) Schumann, RenéThe reuse of code and concepts is an important aspect when developing multiagent systems (MAS) and it is a driving force of agent-oriented software engineering (AOSE). In particular, the reuse of mechanisms like coordination is fundamental to support developers of MASs. In this article we address the selection of effective and efficient mechanisms to coordinate plans among autonomous agents. The selection of coordination mechanisms is, up to now, not covered sufficiently. Therefore, we present the ECo-CoPS approach that defines a structured process for the selection of coordination mechanisms for autonomous planning systems, where the local autonomy and existing planning systems can be preserved.
- KonferenzbeitragHow to Determine the Effectiveness and Efficiency of Coordination and Awareness Support Systems.(Mensch und Computer 2017 - Workshopband, 2017) Oemig, Christoph; Gross, TomCoordination and awareness have been research issues for many years. Effortless coordination and effective awareness support have been goals ever since. Yet, measuring the effectiveness and efficiency of these support systems has remained a complex issue leaving researches with the dilemma that achieving either goal requires some kind of measurement. In this paper we introduce our approach that has the goal to determine whether a certain coordination or awareness support system actually improves a user group’s coordination. We demonstrate how a simple interactive task helps to achieve this goal.
- ZeitschriftenartikelKoordination in Service Value Networks(Wirtschaftsinformatik: Vol. 51, No. 5, 2009) Blau, Benjamin; Dinther, Clemens; Conte, Tobias; Xu, Yongchun; Weinhardt, ChristofDer grundlegende Paradigmenwechsel von traditionellen Wertschöpfungsketten zu agilen, dienstbasierten Wertschöpfungsnetzwerken impliziert neue wirtschaftliche und organisatorische Herausforderungen. Ähnlich wie Koordinierungsmechanismen haben sich Auktionen in Situationen bewährt, in denen heterogene und immaterielle Güter gehandelt werden. Allerdings sind traditionelle Ansätze auf dem Gebiet der multidimensionalen kombinatorischen Auktionen nicht gut geeignet, um den Handel mit komponierten Diensten zu ermöglichen. Eine fehlerfreie Ausführung der Dienste und die damit verbundene Bewertung des Dienstnehmers hängen in hohem Maße von der genauen Reihenfolge der Teile der Komposition ab. Dies bedeutet, dass, im Gegensatz zu Dienstbündeln, zusammengesetzte Dienste nur durch eine gültige Reihenfolge ihrer Komponenten Wert generieren.Der Beitrag stellt ein abstraktes Modell als eine Formalisierung von SVNs vor. Das Modell umfasst die Implementierung eines graphenbasierten Mechanismus zur Allokation multidimensionaler Dienstangebote innerhalb des Netzwerks, zur Sanktionierung für die Nichterbringung und der Bestimmung von Preisen für komplexe Dienste. Der Mechanismus und die Gebotssprache unterstützen verschiedene Arten von QoS-Eigenschaften und deren (semantische) Aggregation. Die Autoren zeigen analytisch, dass diese Variante in Bezug auf alle Dimensionen des Dienstangebots (Qualität und Preis) anreizkompatibel ist. Auf der Grundlage dieser Ergebnisse wird eine numerische Analyse des strategischen Verhaltens der beteiligten Dienstanbieter in Bezug auf mögliche Kollusionsstrategien durchgeführt.AbstractThe fundamental paradigm shift from traditional value chains to agile service value networks implies new economic and organizational challenges. As coordination mechanisms, auctions have proven to perform quite well in situations where intangible and heterogeneous goods are traded. Nevertheless, traditional approaches in the area of multidimensional combinatorial auctions are not quite suitable to enable the trade of composite services. A flawless service execution and therefore the requester’s valuation highly depends on the accurate sequence of the functional parts of the composition, meaning that in contrary to service bundles, composite services only generate value through a valid order of their components. The authors present an abstract model as a formalization of service value networks. The model comprehends a graph-based mechanism implementation to allocate multidimensional service offers within the network, to impose penalties for non-performance and to determine prices for complex services. The mechanism and the bidding language support various types of QoS attributes and their (semantic) aggregation. It is analytically shown that this variant is incentive compatible with respect to all dimensions of the service offer (quality and price). Based on these results, the authors numerically analyze strategic behavior of participating service providers regarding possible collusion strategies.
- KonferenzbeitragLoCo CoCo(Software Engineering und Software Management 2018, 2018) Mohamad, Mazen; Liebel, Grischa; Knauss, EricWe aim to discuss our recent publication in the Information and Software Technology (IST), DOI: 10.1016/j.infsof.2017.08.002. Context: Communication and coordination are essential ingredients to successful requirements and software engineering. However, especially in large organisations, it is difficult to establish and maintain communication channels. Objective: In order to facilitate communication, we investigate automatic construction of social network models from existing requirements and systems engineering models. Method: We conducted a design science research study in three iterative cycles at a large automotive company, and evaluated the outcome based on 15 interviews with practitioners and a survey with 12 participants. Results: The resulting approach, denoted LoCo CoCo, automatically creates and visualises social networks based on selected systems engineering components of real-life, productive systems engineering models. Our results indicate that automatic construction and visualisation of social network models could be feasible and useful to overcome existing communication challenges. Conclusion: Despite a lack of quality in existing social data at the case company, practitioners found LoCo CoCo potentially helpful to overcome existing communication challenges. Additionally, the visualisation could trigger practitioners to keep their social data up to date.
- ZeitschriftenartikelSoftwaregestützte Verhandlung in Supply-Chains(Wirtschaftsinformatik: Vol. 46, No. 6, 2004) Sucky, EricThis paper focuses on the coordination of order and production policies between buyers and suppliers in supply chains. Order quantities and delivery dates have to be negotiated between the supply chain partners. The results of theses negotiations are strongly influenced by the bargaining power of the parties involved. We present a software tool which supports the supplier’s bargaining process. The software tool can be employed for the generation and evaluation of different offers.
