본 연구에서는 허브와 스포크의 입지선정과 차량 경로가 통합된 hub-and-spoke 네트워크 설계문제를 다룬다. Hub-and-spoke 네트워크는 대량화와 공동화를 통해 물류효율화를 실현하기 위한 대표적인 구조로 물류시스템에서 흔히 사용되고 있다. 이러한 물류시스템에서 물류비용의 절감과 고객서비스 향상을 위한 효율적인 수송네트워크 설계는 매우 중요하다. 전통적인 hub-and-spoke 네트워크 설계문제에서 각 스포크의 위치와 화물량이 미리 주어진 상황에서 허브의 입지를 결정하였다. 하지만 스포크 역시 스포크가 담당하는 고객들의 위치와 담당 영역에 따라 그 위치와 수, 그리고 화물량이 변할 수 있다. 또한 정확한 비용산출을 위해서는 스포크에서 고객으로의 수집과 배달을 위한 차량경로가 함께 고려되어야 한다. 다루는 수송망 설계문제는 상호 관련성 있는 여러 부분문제가 결합된 통합문제로써 이를 해결하는 방법으로 기존의 발견적 방법에 의한 순차적 기법은 한계가 있다. 본 연구에서는 공생 진화알고리듬 기반의 방법론을 채용하여 다루는 수송망 설계문제를 동시에 통합적으로 해결할 수 있는 알고리듬을 개발한다. 실험을 통해 개발한 알고리듬의 우수성과 그 적용성을 보인다.

Rapid development of various information technologies creates new opportunities in online and offline markets. In this changing market environment, customers have various demands on new products and services. Therefore, their power and influence on the markets grow stronger each year. Companies have paid great attention to customer relationship management. Especially, personalized product recommendation systems, which recommend products and services based on customer's private information or purchasing behaviors in stores, is an important asset to most companies. CRM is one of the important business processes where reliable information is mined from customer database. Data mining techniques such as artificial intelligence are popular tools used to extract useful information and knowledge from these customer databases. In this research, we propose a recommendation system that predicts customer's purchase intention. Then, customer's purchasing intention of specific product is predicted by using data mining techniques using receipt data set. The performance of this suggested method is compared with that of other data mining technologies.

Mass production system of most manufacturing companies has been supplying us with various useful needs in life for many years. It leads our life to live in comfortable and prosperous circumstances. And we can consider that the contributions of the mass production system to the reduction of different stratification in community remarkable . However, The needs of many clients in these days are various, different, and segmented. It is undesirable to consider every Product on the same basis anymore. So these new requirements of the customers let manufacturing companies be ready for the new production systems which are able to satisfy all the customers, but differently. In this aspects, the customization system could meet new needs of the customers. As we know, cost increase and flexibility matter for the production are main difficulties for the introduction to mass customization. However, to make arrangements for the mass customization systems of the firms is an indispensible factor for maintaining competitiveness and coping with new needs in the future market. We should remember that customers' needs in market will be changing, segmenting, and diversifying, continuously. For this purpose this thesis is tried for studying strategical approach methods of the mass customization.

As products become more complex, short-life cycled and customized, the design efforts require more knowledge-intensive, collaborative, coordinating, and information sharing. By sharing knowledge, information, component and process across different families of products, the product realization process will be more efficient, cost-effective and quick-responsive. The purpose of this paper is to propose an ontology-based product family modeling framework. The ideas of product family, ontology and Semantic Web were investigated in depth. A Semantic Web is originally defined as a web of data that can be processed directly or indirectly by machines, which operates intelligently. A Web Ontology Language (OWL) is designed for use by applications that need to process the content of information instead of just presenting information to humans. For the selected cellular phone product family, ontology was constructed and implemented using prot$\acute{e}$g$\acute{e}$-2000.

The mass housing supply policy of the government has resulted in the customer-centered market, and thereby the age of quality competition in the industry. In line with this trend of quality competition, therefore, this preliminary study aims to investigate the requirements of housing product planning to live up to the needs of customers in terms of quality, and thus analyze the types of quality differentiation of a housing product unit in our housing market. It turned out that many cases attempted differentiation in such ways as merely using luxurious finishing materials and instantly popular environment-friendly materials, and combining partial and limited household items with architectural elements of the facility system. The result of this study shows that the differentiation plan of housing product should be customer-centered, and therefore, focus on quality differentiation through organic combination of architecture-oriented plane and interior elements with technology-oriented facility and product elements. Hereby, in the future, housing product planning should include sustainable differentiation plans with reconsideration of concepts that customers have, and the needed procedure.

Architecture-based competition has become a very important issue in many industries. As companies seek lower cost, fast development, and more customizability at the same time, modular architecture of products and processes seem to be an inevitable choice. Existing literature, however, has only focused on the basic contents of architecture-based competition. Different competitive environments and technological competencies of incumbent companies influence the evolutionary dynamics of dominant architecture of industries. In this paper we suggest a new theoretical framework to deal with the complex co-adaptation process of architecture-based competition. We first explore the emerging modular architecture in Chinese commercial vehicle industry, and then compare it with the architecture strategies of Korean companies. Based on the explorative case study, we propose new hypotheses relating the market demand, technological competencies of major players and dominant architecture in an indus-try.
