Uncertainty in Partner Selection for Virtual Enterprises

LEVERAGING KNOWLEDGE FOR INNOVATION IN COLLABORATIVE NETWORKS

Abstract
A virtual enterprise (VE) is a temporary organization that pools the core competencies of its member enterprises and exploits fast changing market opportunities. The success of such an organization is strongly dependent on its composition, and the selection of partners becomes therefore a crucial issue. This problem is particularly difficult because of the uncertainties related to information, market dynamics, customer expectations and technology speed up. In this paper we propose an integrated approach to rank alternative VE configurations in business environments with uncertainty, using an extension of the TOPSIS method for fuzzy data, improved through the use of a stochastic multiobjective tabu search meta-heuristic. Preliminary computational results clearly demonstrate the potential of this approach for practical application.

LEVERAGING KNOWLEDGE FOR INNOVATION IN COLLABORATIVE NETWORKS

Abstract
This paper presents an innovative approach to support the definition of strategies for the design of alternative configurations of hospital supply chains. This approach was developed around a hybrid Tabu Search / Variable Neighbourhood Search metaheuristic, that uses several neighbourhood structures. The flexibility of the procedure allows its application to supply chains with different topologies and atypical cost characteristics. A preliminary computational experience shows the approach potential in solving large scale supply chain configuration problems. The future incorporation of this approach in a broader Decision Support System (DSS) will provide a tool that can significantly contribute to an increase of healthcare supply chains efficiency and encourage the establishment of collaborative partnerships between their members.

ON THE MOVE TO MEANINGFUL INTERNET SYSTEMS: OTM 2009 WORKSHOPS

Abstract
Current knowledge about the early phases of ontology construction is insufficient to support methods and techniques for a collaborative construction of a conceptualization. Following an approach inspired in cognitive semantics, the application and extension of the Conceptual Blending Theory (CBT) to the realm of collaborative semantic tools is proposed. A formal framework is presented together with some examples in the collaborative networks context. A collaborative semantic architecture is presented. This architecture supports the two components of the proposed method: collective conceptualization and consensus reaching.

LEVERAGING KNOWLEDGE FOR INNOVATION IN COLLABORATIVE NETWORKS

Abstract
This paper presents our method to support the collaborative conceptualisation process focusing our strategy for building consensus in the context of collaborative networks. This new strategy comes from the application of the results and recommendations obtained in an experimental evaluation performed in the scope of a large European project in the area of industrial engineering. The usage of our strategy and the collaborative platform supporting semantic consensus building in the scope of the European research project H-Know is described.

A socio-semantic approach to the conceptualisation of domains, processes and tasks in large projects

Abstract
A case study involving a new method to support the collaborative construction of semantic artefacts in an inter-organizational context is described. The method aims at being applied, in particular, in the early phases of ontology development. We share the view that the development of semantic artefacts in collaborative networks of organizations should be based on a continuous construction of meaning, rather than pursuing the delivery of highly formalized accounts of domains. For that, our research is directed to the application of cognitive semantics results, specifically by developing and extending the Conceptual Blending Theory to cope with the socio-cognitive aspects of inter-organizational ontology development. An evaluation experiment for this method is accomplished in the scope of a large European project in the area of industrial engineering. The method evaluation and its results are described.

Knowledge capability flows in buyer-supplier relationships: Challenges for small domestic suppliers in international contexts

Autores
Moreira, AC;

Publicação
Journal of Small Business and Enterprise Development

Abstract
Purpose: The purpose of this paper is to understand how suppliers have managed to accumulate knowledge in their relationship with large multinational clients. Design/methodology/approach: The methodology was based on four case studies' qualitative data, collected from semi-structured, in-depth interviews. The buyers were selected among the largest MNEs of the electronics, automotive and footwear industries and the suppliers were selected among the set of SMEs supplying to those MNEs. The objective was to assess the supplier's knowledge transfer-oriented capabilities and the buyer's interaction-oriented capabilities in the SBR. Findings: The paper highlights the important leading role of the client in the buyer-supplier relationship involving SMEs as well as the knowledge-sharing atmosphere of successful cooperative relationships. Although it confirms the advantages of alliances for SMEs, knowledge transfer-oriented capabilities, are used by SMEs in order to sustain client satisfaction and to strengthen their core competencies. Despite all efforts of SMEs, if clients are not willing to use interaction-oriented capabilities, buyer-supplier relationships are doomed to failure. Research limitations/implications: One practical implication is that, if SMEs are adequately supported by public policies, it is possible to transfer knowledge from more advanced to less endowed economies. The main limitation stems from the fact that it is not possible to claim generalisation as the research is the result of a series of four case studies. Originality/value: The paper uses dyadic relationships as a viable option to compensate internal knowledge deficiencies of SMEs in their relationship with MNEs. It complements former research as little is known about the importance of alliances in the context of knowledge acquisition and learning in SMEs. It contributes to the SME scientific literature by investigating how SMEs learn from their alliance partners. © Emerald Group Publishing Limited.
