An extended enterprise consists of a set of firms within a value chain that collaborate to produce a finished product. The case of dependable supplier selection, in the context of the extended enterprise, is complex where the focal firm has to select the supplier(s) for a specific class of customers depending on the value of those customers to the focal firm and the extended enterprise. This process requires careful consideration of a set of selection criteria to be used in selecting the suppliers. In this article, a semantic intelligent agent-based architecture and decision support system are presented for selecting dependable suppliers in the context of extended enterprise. tional rents are possible when alliance partners combine, exchange, or invest in idiosyncratic assets, knowledge, and resources/capabilities... that lower transaction costs or permit the realization of rents through the synergistic combination of assets, knowledge, or capabilities” (p. 82).

Firms achieve competitive advantage by creating value-networks of organizations that collaborate to create unique, hard-to-imitate customer value propositions (Frazelle, 2002). Increased competitive environment has brought supply chain management to the forefront, in the context of the extended enterprise, to help companies reduce costs, improve responsiveness, flexibility etc. Supply chain management is a mechanism to monitor and supervise the flow of information, knowledge, products and payments as they move along the supply chain (Ding, Benyoucef, & Xie, 2005). A typical manufacturing company spends a large part of its total costs on purchasing raw materials, subassemblies and components from external suppliers (Weber, Current, & Benton, 1991). In the textile and the semiconductor industries, as in many other industries, businesses are increasingly outsourcing the design and manufacturing of key elements of their products to a number of preferred suppliers (Ding et al., 2005). Competition is not between individual organizations but between competing supply chains, in the context of the extended enterprise (Cohen & Moon, 1990;","PeriodicalId":298071,"journal":{"name":"Int.

STRIDE aims at achieving the right privacy-trust tradeoff among distributed systems entities. This is done by establishing a set of secure mechanisms for quantifying the privacy loss and the corresponding trust gain required by a given network transaction. The privacy-trust quantification process allows the service requestor and provider to create the required trust levels necessary for executing the transaction while minimizing the privacy loss incurred. Moreover, STRIDE supports communication anonymity by associating each communicating entity with an administrative group. In this way, the identification information of the communicating entities is anonymously masked by the identification of their respective groups. The confidentiality, authenticity and integrity of data communication are ensured using appropriate cryptographic mechanisms. Moreover, data sent between groups is saved from dissemination by a self-destruction process. STRIDE provides a context-aware model supporting agents with various privacy-trust characteristics and behaviors. The system is implemented on the Java-based Aglets platform.

Knowledge can be based on observations, recommendations or reputation. However, knowledge is not only related to the concept of “trusting an entity”. Another concept, which is tightly related to knowledge and trust, is privacy. Trust and privacy are two conflicting concepts. This is due to the fact that the more knowledge an entity acquires about a second entity, the more accurate the trustworthiness would be. But, more knowledge about an entity implies less privacy left to that entity. Since both trust and privacy are essential elements in a well-functioning environment, this conflict should be properly addressed. In this paper we present STRIDE, a secure framework for modeling trust-privacy tradeoffs in distributed computing environments. STRIDE employs a set of quantification mechanisms to model privacy loss and trust gain in order to determine the right tradeoff between them. A general framework is developed to select the set of information that minimizes the privacy loss for a required trust gain. STRIDE supports communication anonymity, confidentiality, authentication, and integrity and prevents private data dissemination by employing a self-destruction process.

This paper presents and discusses a conceptual trust framework that models an entity’s trust as a relation whose state gets updated as relevant conditions that affect trust change. The proposed model allows entities to reason about the specification and adaptation of trust that is placed in an entity. An intuitive and practical approach is presented to manage end-to-end trust assessment for a particular activity, where multiple trust relationships are examined in a bottom-up evaluation manner to derive the overall trust for the activity. Finally, Hestia, a novel trust management system that conforms to the formal model’s principles, is described.

For example, a Grid user could choose the trustworthiest site from a pool of available sites to submit a job. A Grid user could specify its trust requirements in a parameterized job description and these requirements will be taken into consideration during job-site matching. Sites, offering computational resources, could be rated based on their reputation among Grid users. This paper discusses a conceptual trust model that captures an entity’s trust as a relation whose state gets updated as relevant conditions that affect trust change. The model allows entities to reason about the specification and adaptation of trust that is placed in an entity and the trust assessment of data that comes through nontrivial chains of processing, spanning multiple entities residing in different administrative domains. The paper also presents the model’s adaptation by a trust management system. To be more specific the discussion evolves around the following topics: • A trust model that allows the establishment and management of trust relationships that correspond to a particular interaction, including a notation for specifying trust relationships that are tied not only to a narrow context but to a broader activity and an intuitive and practical approach that manages end-to-end trust assessment for a particular activity, where multiple trust relationships are systematically synthesized in a bottom-up evaluation manner • A trust management system that implements the trust model’s basic principles. The remainder of the paper is organized as follows. The first section motivates the need for trust expressiveness in collaborative applications and discusses related work on trust modeling and trust management.
