Knowledge in various stages of the product development process has become increasingly important for manufacturing companies to improve their performance, especially for those One-of-a-Kind Production (OKP) companies producing highly customized products. Process knowledge is a very special type of knowledge that controls how products are best manufactured. This knowledge can help OKP companies produce high value-added products with better quality at shorter times and at a competitive cost. Process knowledge is normally hard to capture and manage and is even more difficult to represent. This paper proposes a Parameter Flow Chart (PFC) based new knowledge representation method which efficiently combines parameter information, flow chart technology, and visualization technology. The goal of this research is to provide a user-friendly and effective way of representing process knowledge for OKP companies so they can develop and accumulate their own process knowledge repository. The basic definition and principle of the approach will be introduced first and the software system model then proposed. Two related key issues, the modeling of various chart units used in the PFC approach and dealing with expressions containing various parameters, are discussed in detail. The prototype version of the system has been developed and demonstrated with case studies, which has proven the feasibility of the proposed approach. 相似文献

This study aims to examine the multi-dimensional relationship of total quality management (TQM) and knowledge management (KM) in both service and manufacturing firms in Malaysia. Six key practices of TQM originated from the Malcolm Baldrige National Quality Award (MBNQA) were chosen; whereas the KM elements were made up of knowledge acquisition, distribution and application. Data were gathered from small, medium and large firms from both manufacturing and service sectors. Structural analysis was carried out for the hypotheses and the theoretical model testing. Findings show that strategic planning and human resource management have a positive and significant relationship with the dimensions of KM; whereas process management has significant effects on knowledge acquisition and knowledge distribution. Practically, the findings provide a useful direction for the management team in the manufacturing and service sectors by adopting the relevant TQM practices to further improve the firms’ knowledge management processes. Through a deeper comprehension on the association between TQM practices and the KM dimensions, the management team of these firms can focus their attention, efforts and resources on the specific TQM practices that can ensure successful KM process. 相似文献

A knowledge engineering approach to knowledge management 总被引:4,自引:0,他引:4
Lien F. Lai 《Information Sciences》2007,177(19):4072-4094
Knowledge management facilitates the capture, storage, and dissemination of knowledge using information technology. Methods for managing knowledge have become an important issue in the past few decades, and the KM community has developed a wide range of technologies and applications for both academic research and practical applications. In this paper, we propose a knowledge engineering approach (KMKE) to knowledge management. First, a knowledge modeling approach is used to organize and express various types of knowledge in a unified knowledge representation. Second, a verification mechanism is used to verify knowledge models based on the formal semantics of the knowledge representation. Third, knowledge models are classified and stored in a hierarchical ontology system. Fourth, a knowledge query language is designed to enhance the dissemination of knowledge. Finally, a knowledge update process is applied to modify the knowledge storage with respect to users’ needs. A knowledge management system for computer repair is used as an illustrative example. 相似文献

Information integration enables delivery of the right information to the right user in a timely manner giving manufacturers
a competitive edge in today’s global manufacturing market. However, as enterprise information is usually aggregated from a
variety of heterogeneous information sources, without using an adequate integration framework it is difficult to extract pertinent
information and apply current knowledge to assessing production situations and making informed decisions. This paper investigates
a method of facilitating knowledge synthesis in a distributed computing environment. A formal model of domain ontology and
knowledge base is presented, which aims at providing a vehicle for representing information and knowledge using a common shared
semantics in a given application domain. As a result, a common knowledge representation based architecture is proposed, creating
a foundation for establishing a systematic approach for ease of knowledge synthesis in a manufacturing environment 相似文献
