Commonality strategy is a popular design practice in designing a product line as it enables the firm cost saving and simplification in design, manufacturing, and distribution processes. However the issue of commonality has been mostly analyzed from a profit maximizing firm's perspective and, to our knowledge, there is no literature that deals with the issue from a different perspective. in this paper, we consider the issue of commonality strategy from a social welfare maximization perspective, and argue that commonality strategy used in designing of public goods can bring certain benefits not just for a firm but also for consumers, i.e., for society as a whole. While we assume certain cost saving in production process due to economies of scale under commonality strategy, we conceptualize two different effects of commonality strategy, utility effect due to cost saving and weighted-averaging effect, and show how these two effects interplay to determine the design of common attribute and desirability of commonality strategy. We also discuss how the implementation of commonality strategy differs under different objectives of a product line designer : social welfare and firm's profit maximization.

An architectural practice cannot help involving a social art as its own concept. Especially the school facilities are subjected to the influence of not only the educational needs and the national curriculum, but also the sociocultural context with the change of the times. This study aims to explore the commonality of school facilities and give a theoretic background to the private-public partnership for building new schools and renovating old school buildings. After it studies about the relationship between the roles of school and community, it classifies' the commonality of school facilities' into 4 categories the educational commonality, school as the public good, the esthetic functions to society and the social role as community center. Finally, this paper proposes some methods for improving the commonality of school facilities.

The purpose of this paper is to understand the meaning of 'institution' in Louis Kahn's architecture and to reveal that it is expressed through singularity and commonality, which have two aspects; formal-material(eidos-hyle) aspect and phenomenological aspect. Under these recognitions, this paper shows the detail analysis on design process of Phillips Exeter Academy Library, focusing on his writings and sketches. The results are as follows. First, the basic form is maintained through the design process of the Exeter library, and it is derived from the consideration of the human activities in the library. And second, each 'room' of the library acquires its singularity through structure and light. And the 'plan' is based on the commonality inherent in the singularity of each room. And the last, singularity and commonality are revealed not only In the relation of architectural elements but also In the relation with man and architecture.

This paper presents a commonality and variability analysis method for UML CASE tool frameworks. Commonality and Variability analysis increase extension and reusability by separating common area and variable area. We suggest class category based on property and the notation to represent commonality and variability. It is also implements frameworks based on analysis method and verify method using defect removal efficiency.

Service engineering is a new discipline which aims at basically understanding of service and a concrete methodology using engineering approach for service design. In this paper is introduced the serviset graph [7] which is a comprehensive concept to represent service products, processes, and operation activities. The proposed concept is a degree of commonality index in a service product in order to deal with service mass customization using the input-output analysis in economic model.

Vernacular houses in Southeast Asia are basically post and beam structures raised on pillars, with gabled roofs. They were designed and built by the people themselves to meet specific needs, accommodating the values, economies and ways of life of cultures that produce them. Their forms and housing cultures are very various according to the country and the region. But based on the common history and culture, the vernacular houses in Southeast definitely have commonality. The purpose of this study is to analyse the commonality and diversity of the vernacular houses in Southeast Asia in the aspect of two different perspectives. One is the climate perspective, for which the analysis was made on the primary characteristics such as the climate, material, structure of the vernacular houses. The other one is the social-cultural perspective which try to find the religion, belief, life style and social and family relationship which controlled the forms of the housing under the surface. As a result, this study summarise and find the outstanding and unique meaning and definition of the vernacular houses in Southeast Asia.

Although German Neo-expressionism and Chinese modern ink painting are separated by thousands of miles in geographical space, they have a similar origin time, and there are many commonalities between them. In the aspect of creative attitude, artists of both styles can absorb and resist foreign styles, return to the past and conquer the tradition. In the aspect of formal expression, the objects of both paintings are representational rather than realistic, and the material characteristics of the media are emphasized. At the inner spiritual level, both expressionism and modern ink painting pay attention to social concern, and show the uncertainty of postmodernism together. The commonality between German neo-expressionism and Chinese modern ink painting does not mean to eliminate the difference, but to maintain the coexistence of difference and commonality.

To compete global marketplace, many firms are adopting product families to increase variety, satisfy customer requirements, shorten lead-times and reduce costs. The key to a successful product family is the platform from which it is derived. When designing product families, it is important to resolve the tradeoff between product commonality and distinctiveness. To measure the commonality within a product family, it is necessary to develop the commonality index. It utilizes different parameters such as the number of common components, their cost, their manufacturing processes and so on. This paper present a new product family assessment index using the benchmarking method and considering environmental performance called green product family index(GPFI). Through the comparison analysis between some previous developed commonality indices and GPFI, we verify the suitability and effectiveness. Eventually, the proposed a new green product family assessment index can be helpful to design and develop the environmentally conscious product families.

고객의 요구에 대한 빠른 대응과 유연하고 효율적으로 새로운 제품을 적기에 개발하기 위해서는 제품 플랫폼에 기초한 대량 맞춤이 절실히 요구된다. 이러한 목적을 달성하기 위하여 기업들은 상대적으로 생산비용을 낮게 유지하면서 대량생산의 이점을 유지하고 동시에 고객의 요구사항을 만족시키기 위해, product family를 도입하고 가능하면 작은 변화를 통하여 제품의 다양성을 유지하고자 한다. Product family를 설계할 때 중요한 이슈는 제품의 공통성과 차별성간의 절충점을 어떻게 찾아낼 것인가인데, 이를 위하여 개발된 것이 product family내에서 평가하는 방법이다. 본 연구에서는 product family의 공통성을 평가하기 위해 개발된 대표적인 7가지의 방법을 여러가지 측면에서 비교분석한다. 이를 위하여 두 개 회사의 컴퓨터 마우스 제품군을 대상으로 공통성 평가를 위한 비교연구를 수행하였다. 추가적으로 본 연구에서는 product family를 설계하거나 재설계할 때 공통성 평가지 수의 효과적이고 효율적인 사용방안을 위한 전략도 제시하였다.

When you develop component, you can offer reusability and extension by analyzing commonality and variability about attribute and behavior. Therefore Component that analyzing commonality and variability are use for the purpose of reducing discord of function and adaptedness. I wish to research reusability and extension of component by analysis commonality and variability of component that exist by domain in this paper, extractfunctionofcomponentbybehavioranalysis.
