In this paper, we develop an efficient approach to solve a continuous review inventory system with a budget constraint when the semi-finished product and optional components are required to be assembled. We are, in particular, interested in a budget constraint that includes a service level. The service cost, such as labor and facility costs, tends to increase as the service level increase, and it makes the problem difficult to solve. Assuming that the reorder point for a semi-finished product is given, we show that the order quantity for the semi-finished product and the order quantity and reorder point for optional components can be determined by minimizing the total cost that includes setup cost, inventory holding cost, and shortage cost. The performance of the proposed approach is tested by numerical examples. By using sensitivity analysis, we conclude that, as the reorder point for semi-finished product increases, the order quantity for semi-finished product increases, whereas the order quantity and reorder point of optional components decreases.

소프트웨어 프로덕트 라인을 구축하고자 할 때，첫 단계 활동은 도메인 분석을 통해 요구사항 들에서 가변성을 식별하는 것이고， 다음 단계는 일련의 관련된 프로덕트들의 전체적인 구조를 나타내는 도 메인 아키텍처를 개발하는 것이다 도메인 아키텍처는 소프트웨어 프로덕트 라인에 포함되어 있는 프로덕트들의 공통성과 가변성을 기술함으로써 프로덕트 라인의 핵심자산이 된다. 핵심자산의 가변성은 개발 프로세스가 진행됨에 따라 식별될 수 있는 가변 요소의 종류와 상세화 수준이 달라지기 때문에 아키텍처 수준에서 식별될 수 있는 가변성을 정의하고 이를 체계적으로 식별하여 아키텍처 모델에 명시적으로 표현하는 것이 중요하다. 아키텍처 수준에서 고려해야 하는 가변성은 아키텍처 구성 요소들에서 발생하는 가변성 뿐만 아니라 이들의 구성(configuration) 관계를 나타내는 모텔에서 나타나는 가변성들까지 고려해야 하기 때문에， 이들 사이의 복잡한 관계를 이해하고 표현하는 것은 매우 힘든 일이며 이에 대한 기존 연구가 부족한 실정이다. 본 논문에서는 공통성과 가변성이 명시적으로 고려되는 프로덕트 라인의 핵심 자산으로서 도메인 아키텍처를 개발하는 방법을 제시한다. 이를 위해， 최근 Object Management Group(OMG)에서 채택한 재사용 자산 병세(Reusable Asset Specification; RAS) 모델을 확장하여 공통성과 가변성 개념이 명확히 정의된 도메인 아키텍처 메타모델을 제시한다. 제시되는 메타모델에는 아키텍처의 구성요소들이 정의되어 있으며， 각 구성요소와 모텔에서 식별 될 수 있는 가변성이 상세화 수준에 따라 두 가지 형태로 구분되어 제시되어 있다. 또한 본 메타모델을 기반으로 특정 도메인에 대한 아키텍처에 가변성이 명시적으로 표현되는 방법을 보인다.

The concept of integrated product information has been universalized so that many manufacturing industries have applied the concept to their production system. The field of PDM (Product Data Management), which is one of the core components of the integrated product information, is not an exception. Therefore, various PLM (Product Lifecycle Management) software providers are in process of suggesting the PDM solutions. As the PDM solution is widely adopted in the manufacturing industries, the successful application of the solution has been gathering more strength in manipulation of the product information. However, the standardized implementation methodology is stuck in the basic level contrast with the enhanced PDM's functionality and capability. Present study refers to the application of UML (Unified Modeling Language), which is an object oriented modeling description, to PDM system development procedure. The advantage of UML is its efficiency and effectiveness in handling complex requirement often found in PDM implementation works. This paper shows the integration of PDM and UML proposes a philosophy for the support of requirement analysis throughout the full implementation of PDM system.

The purpose of this research was to develop a typology of fair-trade apparel consumers and present a clear overview of the influence of product knowledge on consumer behaviors. A two-step cluster analysis was used to classify respondents into sub-groups based on their level of self-perceived knowledge and purchase experience. In addition, ANOVA was used to test the predictive validity of the cluster solution. Income was the only demographic variable that significantly differed across groups. The more familiar and more experienced group had higher income than the other groups. Psychographic data showed that attitudes and moral norms varied across groups. The more familiar and more experienced group had more positive attitudes and higher level of moral norms than the less familiar and less experienced group. In terms of behavioristic data, groups differed significantly in purchase intentions and willingness to pay more for fair-trade apparel. That is, the more familiar and more experienced group was willing to pay more and had higher purchase intentions than the less familiar and less experienced group. Overall, the level of product knowledge and purchase experience were considerably low. This study thus confirmed the need to increase consumers' familiarity related to fair-trade apparel products.

In today's society with its emphasis on unlimited information access, control of available information about high-technology products is often vital to their success. When a product is released, consumers may initially be attracted through information about its remarkable internal and external features. They may also perceive a degree of congruence between their own personalities and the product image as more information becomes available over time. Consumers' changing impressions of the product may influence personality congruence negatively or positively. These changes and their effects on preference for high-technology products are the focus of this paper. A survey was given to a sample of 206 students at K University to investigate the degree to which consumer behavior can be influenced by personality congruence. The need for clear and definite product knowledge in this process and the effect of product information on preference were also investigated. Three analyses were conducted. The results of Analysis 1 showed the influence of personality congruence on preference for high-technology products. Judgments about personality congruence were based on non-compensatory rather than compensatory information processing. The respondents considered certain aspects of a product's personality rather than the product as a whole when making preference decisions. The results of Analysis 2 indicated that when less information was available about a product, consumers who perceived high personality congruence with the product tended to have higher preference for it compared to those who perceived low personality congruence with the product. On the other hand, when consumers were given more information, no difference was observed in the impact of personality on preference between perceived high and low personality congruence. Lastly, the results of Analysis 3 showed that when consumers with high need for closure (NFC) perceived high congruence between their own personalities and a product, objective information regarding the product was not used in decision-making: instead, judgments about the product were based on perceived personality congruence. On the other hand, high-NFC consumers who perceived low personality congruence between themselves and the product tended to require more information about the product in order to give it a positive evaluation. In contrast, low-NFC consumers who perceived high personality congruence felt comfortable with large amounts of information. For low-NFC consumers who perceived low congruence, the level of information had no influence on preference.

This study investigate the role of consumer's perception of quality in new technology adoption process in China which is given little attention in the field of Information System and Communication Technology. Here, we developed a simple model in the level of consumer perception by exploring the antecedent of perceived quality. Three factors are introduced as determinants of perceived quality: perceived usefulness, perceived risk and trialability. An empirical study is conducted with analysis of the adoption mechanism of a new innovative product. Data analysis results support some of our proposed hypotheses. It indicates that perceived quality is positively related to the adoption intention and fully mediates the relationship between triablility and purchase intention. And we conclude that a product's perceived quality plays an important role in adoption intention. And what makes Chinese customers perceive product's quality good is a trialability of a product. This suggests that when market managers plan to launch products in China, they need to craft an effective strategy based on the market system of the consumer especially understanding the consumers' critical factor for adopting a new product. Chinese are more interested to purchase a product with free trial and free experiential period, therefore, suggesting an advertisement highlighting the trialability of a product is possible in China.

본 연구는 제품보증의 유형인 명시적 보증과 묵시적 보증이 소비자의 제품에 대한 태도에 미치는 영향을 제품보증과 관련된 선행연구들을 탐색하여 살펴보았다. 이에 따른 주시험 효과가 제품유형(탐색재 vs 경험재) 및 제조업체의 기업윤리 수준(고윤리 vs 저윤리)에 의해 조절되는지를 상호작용 효과의 차원에서 고찰하였다. 실증분석 결과에 의하면 소비자의 제품에 대한 태도는 제품보증이 명시적일 때가 묵시적일 때보다 높게 나타났다. 그리고 제품보증의 유형에 따른 주시험 효과는 해당 제품이 탐색재일 때보다 경험재일 때가 더 크게 나타났으며, 제조업체의 기업윤리 수준이 높을 때보다 낮게 인식할 때가 더 크게 나타났다. 다만, 이러한 조절효과는 두 가지 종속변수 중 제품태도는 통계적으로 유의한 결과를 보이지 않았고 구매의도에서만 유의한 결과가 나타났다.
