Most of the companies are forced to cut down the manufacturing cost to survive in the competitive environment. Among others, material distribution cost alone takes substantial portion of the total manufacturing cost. In this study, we investigate the waiting phenomenon in the toll gate and propose a new toll booth layout to reduce the waiting time, thereby reduce the total material distribution cost. SIMAN, a simulation language, is employed to evaluate the proposed layout. The experimental results show that the layout reduces the waiting time significantly. Furthermore, the result indicates that determination of the intermediate buffer space affects the performance of the proposed layout.

This paper investigates the methodology to develop a layout of the simulator for measuring and evaluating human sensibility. Since the simulator layout is different from general building layouts in that it is organized in order to communicate systematically between facilities, laboratories to evaluate human sensibility and equipments to support experiments in simulator, two approaches based on eigenvector and cut tree are applied to develop a simulator layout. Qualitative input data (relationship chart. space requirements for each laboratory and equipment) are obtained and transformed into quantitative data. The information obtained by two approaches provides several meaningful clues to generate the simulator layout. The simulator layout is presented based on the obtained information by two approaches. Extracted quantitative data by using eigenvector and cut tree are meaningful of generating the simulator layout.

A tree structure model has been proposed for representing the unequal-area facility layout. Each facility has a different rectangular shape specified by its area and aspect ratio. In this layout problem, based on the assumption that the shop floor has enough space for laying out the facilities, no constraint is considered for a shop floor. Objectives are minimizing total part movement between facilities and total rectangular layout area where all facilities and dead spaces are enclosed. Using the genetic code corresponding to two kinds of information, facility sequence and branching positions in the tree structure model, a genetic algorithm has been applied for finding non-dominated solutions in the two-objective layout problem. We use three kinds of crossover (PMX, OX, CX) for the former part of the chromosome and one-point crossover for the latter part. Two kinds of layout problems have been tested by the proposed method. The results demonstrate that the presented algorithm is able to find good solutions in enough short time.

본 연구는 현대의 대표적인 주거양식인 아파트 공간과 우리 전통미를 살린 한옥표준평면도의 공간 배치 등을 비교 분석한 것이다. 연구 방법은 객관적인 분석을 위하여 공간구문론(Space Syntax)을 이용하여 각공간의 특성을 분석하였다. 연구결과는 다음과 같다. 1) 아파트 공간은 생활의 편리함과 용도의 명확한 구분 때문인지 공간이 세분화된 반면에 전통한옥 평면은 각 실이 다양한 용도로 사용함에 따라 아파트보다 각 실의 공간이 세분되지 않았다. 2)한옥평면도에서 대청이 거실로 변화하였을 뿐 두 평면도 모두 시대의 변화에도 불구하고 거실공간이 통합도가 가장 높았다. 3)한옥공간은 서로 공간이 통하는 통합성 성격이 강하지만 현대화된 한옥표준설계도는 분격성 공간의 성격이 강한 것으로 분석되었다. 4)일반적인 생각과 달리 아파트에서 안방의 통합성이 높았고 한옥평면도에서는 침실과 안방은 분격성이 높았다. 5)한옥평면도에서는 옛날과 달리 툇마루의 기능이 많이 감소한 반면에 사랑방에 부속된 누마루가 분격성 공간으로 분류되었다. 아파트에서는 피난공간이 분격성이 가장 높은 것으로 분석되었다. 즉 한옥표준설계도는 현대의 생활에 적응하면서 변화되어 있었다.

The existing universities enlarged the scope, filled up the facilities. And many new universities are founded by increase of university students, the change of curriculum and extension of installations for new curriculum. However, the planning for university campus hinders desirable activities in campus and also the origin function of university, because of the problems caused by an application of a uniform planning standard that lacks in logical analysis and such a short step as the occasion demands for the growth and the change of the university campus changing more rapidly than any other field in society. This dissertation is for space program beginning from architectural explanation and basic planning concluding a general structure-planning for land utility, circulation planning, and building layout planning in order to find the practical solution for the applicable campus plan. The contents of this dissertation is summarized below. First, I studied the characteristics of the university, the structure of the university facilities and the expansion the development process of the campus. Second, through the case study of domestic campus planning, I analyzed the characteristics and the problems about space programming, facility layout planning, circulation planning and exterior space planning. Third, in the basis of the above analyses, I set up the directions of comprehensive campus master plan.

This study is to analyze the building layout of traditional government office building in Chungchong province with Chungchong-do regional maps and Eupjis(邑誌) being compiled in the late Chosun dynasty. The building layout of government office in Chungchong-do is followed in the wake of the spatial structure, Sam-Jo(三朝, three reign) and Oejeon-Naejeon(外殿-內殿), of Chosun dynasty palace. The planning principle of Sam-Jo at government office, Dongheon(東軒) territory for rule administration corresponds to Chijo(治朝) with a local governor who is the ruler, as for the Naea(內衙) territory which a family of him and he lives in, it is corresponded to Yeonjo(燕朝), and in the job space of Ajeon(衙前), it is corresponded to Oejo(外朝). As for the application of the inside and outside principle of provincial government office, Dongheon is corresponded to Oejeon and Naea to Naejeon. A compositive and an approach axis of government office in Chungchong-do is correspond with Dongheon in the center, and these axes form an central axis and an entry space of government office included Oesammun(外三門) Naesammun(內三門) Dongheon or Naea. Because an essential performance of provincial government office is provincial administration, the layout configuration of government office is a function, which is an expression of an official institution.

The semiconductor industry is highly capital and technology intensive. Technology advancement on circuit design and process improvement requires chip makers continuously to invest a new fabrication facility that costs more than 3 billion US dollars. Especially major semiconductor companies recently started to discuss 450mm fabrication substituting existing 300mm fabrication of which facilities were initiated to build in 1998. If the plan is consolidated, the yield of 450mm facility would be more than doubled compared to existing 300mm facility. In steps of this important investment, facility layout has been acknowledged as one of the most important factors to be competitive in the market. This research proposes a new concept of semiconductor facility layout using hexagonal floor plan and its compatible material flow pattern. The main objective of this proposal is to improve the productivity of the unified layout that has been popularly used to build existing facilities. In this research, practical characteristics of the semiconductor fabrication are taken into account to develop a new layout alternative based on the analysis of Chung and Tanchoco (2009). The performance of the proposed layout alternative is analyzed using computer simulation and the results show that the new layout alternative outperforms the existing layout alternative, unified layout. However, a few questions on space efficiency to the new alternative were raised in communication with industry practitioners. These questions are left for a future study.

The purpose of this study was to survey teachers' perception of classroom space utilization through analyzing the physical environment of elementary school classrooms (56 classrooms in 10 schools). Most of the teachers arranged desks in the two person parallel type (sectional layout : standard type) for their classes. Although the number was small, some classrooms used the T type, H type, U type, group type, and the teachers of such cases used these layouts for children's play activities or group learning. Some teachers changed the desk layout depending on the contents of learning or for different atmosphere of class, but about 40% of the teachers used the same classroom layout without any change during a semester. When the teachers' perception of classroom space utilization was examined according to the type and change of desk layout, the quantity and characteristics of posts, the position of posting spaces, and the size of activity spaces in the classroom, most of the teachers tended to be conventional without any characteristic, and only 16% of them were relatively active in utilizing classroom spaces. In addition, teachers of a relatively small class were more active in utilizing classroom spaces. In particular, perception was very low to utilize the classroom as a space for children's life or play activities or various types of learning. These findings suggest that it is necessary to improve teachers' perception of classroom space utilization in the future.
