摘要

虛擬企業(Virtual Enterprise)是有效的提昇企業競爭力的策略之一，主要是透過產品的協同設計、生產、組裝與行銷。即時及安全的知識分享是虛擬企業成功的關鍵，本研究針對虛擬企業知識存取控制及分享之模型、方法與技術進行發展。首先，本研究提出一個本體論為基的知識分享模型及一個多層式的知識表達架構，以此兩者為基，設計一個能夠促進知識分享的虛擬企業知識存取控制模型。此模型中，使用者知識的存取權限可以分成基本授權及延伸授權兩種；前者是由評估4W(Who, What, When and Where)所獲得，而後者是由考慮三維的領域本體（產品本體、組織本體及活動本體）中的知識概念間的關連性來決定權限的擴散(Propagation)。藉由本研究使虛擬企業更容易的有效管理及分享跨企業的知識。

Virtual Enterprise (VE) is one of the most promising strategies to enhance global competitiveness, via collaboration on product design, production, assembly and marketing. Efficient and secure knowledge sharing is one of the key factors to the success of VE. This study focuses on the development of approach, model and technology for knowledge access control and sharing. First, this study proposes an ontology-based knowledge sharing model and a multiple-layer knowledge representation framework, on which a knowledge access control model for knowledge sharing in virtual enterprise is proposed based. In this proposed model, user's authorization to using knowledge for completing the responsibilities in a VE is classified into two different levels the basic privileges and the extended privileges. The former are evaluated from four-dimensions, i.e. who, what, when and where, while the latter is decided by considering the relationships between concepts in a predefined three domain ontologies (product, organization and activity ontologies). This study facilitates the management and sharing of knowledge involved in a VE.
