As modular production becoming increasingly widespread in globalized manufacturing industries, sub modules or parts of the final product are being provided by many suppliers. Some part suppliers design their own products for themselves. In some cases, part suppliers provide the same type of product to multiple OEM companies. Because all part suppliers and OEM companies typically cannot use the same CAD system, engineering change in the CAD model of one company cannot be directly propagated to related CAD models of other companies. Even if two companies use the same CAD system, it may be difficult to share their CAD model owing to corporate security policy. In this paper, a neutral reference model that consists of a neutral skeleton model and an external reference data model is proposed as a new medium for the sharing and propagation of engineering change information among collaborating companies.

Forming a network, through Social Network Services (SNS), among a group of people who share the same hobby or interests could increase the information sharing among the members at an exponential rate. Moreover, SNS users' behavior extends beyond the traditional introverted consumption behavior to a proactive behavior by owning or actively sharing product information. For firms, such proactive consumer behavior translates into marketing effects such as the word of mouth (WOM) effect. Therefore, SNSs are accepted not only as a communications channel between firms and consumers but also as marketing channel, suggesting the possibility of a new revenue source. In this context, we will explore into the factors of SNS contents which conserve firms' image and product information, and effects of the factors on consumer attitude and WOM.

In the recent manufacturing industry almost all sorts of activities tends to be digitized and networked to enhance the comprehensive efficiency of the enterprise. In that sense, enterprise informatization system as well as product information sharing system plays an important role, and those application systems are to be integrated in a smooth manner. In this paper, a prototype of an web-based product information sharing system is developed, which integrates information on technical documentation and parts information together. The prototype also integrates information on the implementation strategies for the enterprise informatization.

Currently, it is necessary to share and exchange drawing information between 2D and 3D data in AEC(Architecture, Engineering & Construction) fields. The authors suggest an information model framework to express IFC(Industry Foundation Classes)-based drawing of 3D AEC products as 2D drawing. In this study, 1) an information framework has been developed to enable sharing and exchange of AEC product model by adding various information factors, 2) standardized APIs and an IFC2DBrowser are developed.

This paper introduces an approach to semantic mapping using Product ontology for CPC environment. In CPC environment, it is necessary that the participants in a product life cycle should share the same understanding about the semantic of product terms. For example, they should know that although 'COMPONENT' and 'ITEM' are different word-expressions, they could have the same meaning. In order to handle such terms in the information system, it is desirable that the system automatically recognizes that the terms have the same semantics. Serving this purpose, we described an ontology design methodology using first order logic, knowledge interchange format, and knowledge engineering process. In our approach, we investigated domain knowledge of the Bill Of Material, and then designed Product ontology of it. Based on the ontology, we described syntactic translation, semantic translation, and semantic mapping procedure with an example.

As the networks (i.e., intranet and internet) proliferate all over the world, it is inevitable to move some (or all) of the enterprise activities into virtual spaces. Differently from business data, product data have complex semantics and thus are not properly exchanged among different application programs. Even though some neutral formats of product data have been developed by standard organizations, exchanging them among various application programs still needs the comprehensive understanding of the complex semantics. Recently, it is widely recognized that capturing more knowledge is the next step to overcome the current difficulties on sharing product data. In this paper, we utilize the ontology concept in order to facilitate information search far product data in the internet environment. A prototype of search system implemented using the ontology for automobile product data is presented.

고객에 대한 빠른 대응과 유연하고 효율적으로 새로운 제품을 적기에 개발하기 위해서는 제품 플랫폼에 기초한 대량 맞춤이 절실히 요구된다. 본 연구의 목적은 대량맞춤을 구현하는 방안으로서 제품 가족 모델링을 위한 방안과 온톨로지를 이용하여 제품개발 관련 정보를 공유하기 위한 방안을 제시하고자 한다. 제품들이 점점 복잡해지고, 수명이 짧아지고 고객맞춤으로 되어감에 따라서 이를 실현하기 위한 디자인 노력은 보다 더 지식 집약적이고, 협업을 요구하며 정보의 공유를 필요로 하고 있다. 일련의 연관된 제품군간에 지식, 정보, 구성부품, 제조공정을 공유함으로서 제품 실현화 과정은 더 효율적이고 비용 대 효과가 좋고 고객에 대한 빠른 반응이 가능할 것이다. 본 연구에서 제시할 주요 내용으로는 제품가족 디자인을 위해서 필요한 기능분석, 제품가족 지도 및 가족 모델링을 위한 방안과, 제품가족 개발을 위해서 온톨로지 이용방안이다. 구현을 위해서 휴대전화기의 제품가족 분석과 분해에 의한 기능 분석 및 이 제품가족에 대한 온톨로지를 구축하였다.

정보의 양이 많아짐에 따라 많은 양의 정보를 효과적으로 관리, 운용할 수 있는 데이터 마이닝 기법의 연구가 활발해졌다. 다양한 데이터 마이닝 기법들이 연구되었는데 그 중에는 프라이버시를 보호할 수 있는 프라이버시 보호 데이터 마이닝(Privacy Preserving Data Mining) 연구도 진행됐다. 프라이버시 보호 데이터 마이닝은 크게 연관규칙, 군집화, 분류 등의 알고리즘이 존재한다. 그 중 연관규칙 알고리즘은 데이터간의 연관규칙을 찾아내는 알고리즘으로 주로 마케팅에 주로 사용된다. 본 논문에서는 Shamir의 비밀 분배 기법을 이용하여 다자간 프라이버시 보호 데이터 마이닝 환경에서 단일 비트가 아닌 멀티 비트 정보를 공유할 수 있는 내적연산 기법을 제안한다.

More and more cyber shopping malls, one of the new promising Internet businesses of today, are opening business everyday. And instead of the ordinary image and text type of product display, buyers can now view products from any viewpoint through 3D images and also get more detail information on the product more easily thanks to the new VP technology, visual tools, and statecharts. However the currently used virtual prototyping supporting method does not consist of any database support for sharing the data from different virtual prototype developments and reusing the data in developing other prototypes. And in cases of custom order products, there is no linkage with the virtual product database that enables buyers in cyberspace such as cybermalls to try out the products before purchasing. This paper is purported for being applied as the basis for planning the construction of a complete CRM method applied cyber shopping mall that can accommodata all the demands and requests from customers. And the database supporting VP framework that supports data sharing and collaboration between virtual prototype developers and manufacturing custom order products is suggested for this purpose.

Purpose This study empirically investigated the impact of information technology(IT) capability on the co-innovation with suppliers and the effects of the co-innovation with suppliers on the product and process innovations in manufacturing firms. We demonstrated that IT promotes innovations trough the sharing of knowledge with suppliers. Design/methodology/approach The empirical data were collected through post-survey. 97 valid survey data were finally collected. With a multiple-regression analysis, we confirmed the influence relationships among critical variables. Findings In the empirical results, it was found that IT integration positively and significantly influences the amount of inter-organizational information exchange with suppliers. The results showed that the inter-organizational information flow with suppliers has a positive and significant impact on the inter-organizational learning with suppliers. It was also observed that the inter-organizational learning with suppliers facilitates and promotes the co-innovation with suppliers. From these results, it is concluded that the co-innovation with suppliers is activated through the knowledge transfer or sharing caused by an inter-organizational information flow or learning. Finally, the positive effects of the co-innovation with suppliers on the product and process innovations were empirically confirmed. Thus, it is suggested that IT capability influences innovations through the co-innovation with suppliers caused by an inter-organizational information flow.
