This work is concerned with the conduct of Multiple Criteria Decision Making (MCDM) by intelligent software agents trading digital commodities in Application Layer Networks (ALN) such as grids or clouds.
These agents consider trustworthiness in their course of negotiation and select offers with respect to product price and seller reputation. To automate the selection process, we seek an appropriate MCDM method that provides clear advice for an agent prior to negotiating. We compare eleven well-known MCDM methods and choose the TOPSIS approach of Hwang and Yoon since it produces
comprehensible and plausible results with a justifiable amount of effort. We modify the method and present a draft named xTOPSIS that promises intertemporal performance analysis for further automatation. The resulting tool is finally tested and
evaluated in the context of a scenario similar to the eRep - Social Knowledge for e-Governance project.

    Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

    This study explores the application of Multiple Criteria Decision Making (MCDM) methods in the context of Application Layer Networks (ALNs), particularly focusing on the role of intelligent agents negotiating commodity trades. The central aim is to develop a suitable MCDM approach that effectively supports agent decision-making in ALNs, incorporating considerations such as trustworthiness and seller reputation.
    • The role of trust in e-commerce environments
    • The use of MCDM techniques for decision-making by software agents in ALNs
    • The importance of reputation and trustworthiness in agent negotiations
    • The design and evaluation of a modified TOPSIS method for intertemporal performance analysis
    • The application of MCDM in a real-world scenario similar to the Social Knowledge for e-Governance project
