Collaborative filtering, one of the most widely used techniques to build recommender systems, is based on the idea that users with similar preferences can help one another find useful items. Credit card user behavior analytics show that most customers hold three or less credit cards without duplicates. This behavior is one of the most influential factors to data sparsity. The 'cold-start' problem caused by data sparsity prevents recommender system from providing recommendation properly in the personalized credit card recommendation scenario. We propose a personalized credit card recommender system to address the cold-start problem, using multiple user profiles. The proposed system consists of a training process and an application process using five user profiles. In the training process, the five user profiles are transformed to five user networks based on the cosine similarity, and an integrated user network is derived by weighted sum of each user network. The application process selects k-nearest neighbors (users) from the integrated user network derived in the training process, and recommends three of the most frequently used credit card by the k-nearest neighbors. In order to demonstrate the performance of the proposed system, we conducted experiments with real credit card user data and calculated the F1 Values. The F1 value of the proposed system was compared with that of the existing recommendation techniques. The results show that the proposed system provides better recommendation than the existing techniques. This paper not only contributes to solving the cold start problem that may occur in the personalized credit card recommendation scenario, but also is expected for financial companies to improve customer satisfactions and increase corporate profits by providing recommendation properly.

Since their first inception a few decades ago, software components have received much attention mainly due to their alleged benefits of quality and productivity improvement. Despite this, it is yet to be agreed upon what and how components should be designed. This paper aims to bridge the gap by proposing a collaborative process where the voice of the customer is captured and documented by employing the event and entity models. These requirement elements (WHAT) are cross-tabulated in three relation matrices in accordance with the weights provided by the business users. The requirements are fed into the algorithm invented by the authors to optimize the component grouping (HOW). This collaborative process has been successfully validated at an enterprise wide software development project. The process was effective to help the users more actively involved in the design of the system and made the whole process faster and more adaptive to the changes.

1990년대 후반부터 신발의 패션화 경향, 고객 요구의 다양화 등에 힘입어 국내신발산업이 서서히 부흥하고 있다. 그 동안 국내에서는 신발산업이 사양산업으로 인식되어 생산시설이 해외로 이전하는 추세였지만, 최근에는 신발 소재 및 부품 생산의 핵심역량과 국제적 분업체계를 결합하여 국내 신발제조업의 경쟁력이 회복되고 있다. 이러한 국제적인 분업체계를 효과적으로 활용하기 위해서는 신발산업의 공급망관리가 시스템에 의해 운영되어야 한다. 현재 신발산업은 다양한 고객 요구사항 및 제품 납기일자의 지속적인 단축에 직면하고 있다. 이러한 환경변화에 대처하기 위해 기업내부의 최적화만으로 경쟁우위를 화보하기에는 한계점에 이르렀다. 이제는 신발산업 공급망 전체의 최적화를 통한 기업 상호간의 윈-윈(Win-Win) 전략을 구사할 필요가 있다. 본 연구에서는 신발산업의 효율적인 공급망 관리와 단납기 요구체제 등의 환경변화에 대처하기 위해, 기업간 협업적 비즈니스에 기반한 공급망관리 시스템을 설계하였다. 기업간 정보 전달과 공유를 위해 e-비즈니스 프로세스, 문서 처리방법 및 표현방법 등을 포함하는 정보활동의 총체적 개념의 ebXML(electronic business eXtensible Markup Language) 프레임워크에 기반하였다.

Purpose - This study primarily aims to represent the current trend of research on CPFR as a promising supply chain collaboration program and proposes a new framework for analyzing any collaboration programs in terms of three key collaborative features. Research design, data, and methodology - This study employs a literature review of selected studies that conduct research on CPFR. CPFR is analyzed based on the proposed framework that characterizes collaboration programs in terms of three key collaborative features. Results - The analysis based on the proposed framework reveals that the current form of CPFR continues to have some collaborative features that are not fully utilized to create an advanced collaboration program. The literature review indicates that most past studies ignore critical issues including the dynamic nature of the multiple-stage supply chain system and negotiation process for collaborative agreement in CPFR implementation. Conclusions - Results indicate that CPFR can become a better supply chain collaboration program by incorporating coordinative cost payment and joint decision making processes. Based on observations on the existing literature of CPFR, this study indicates several important issues to be addressed by future studies.
