  • Layout 문제는 매우 복잡한 의사결정과정이며, 이론적인 면보다는 논리를 바탕으로 한 경험적 결정이 많이 필요한 분야다. 이 논문에서는 프레스와 용접공정을 중심으로 하는 두 자동차 부품 생산업체가 한 업체로 통합되면서 새로운 공장으로 이전하는 과정에서 발생한 Layout 문제를 해결해 나가는 방법을 소개하였다. 추진하는 과정에서 기존의 개념모델을 일부 수정하여 적용하였으며, AutoCAD, FactoryFlow와 같은 소프트웨어를 이용하여 정량적 평가를 지원하였다.

  • This paper deals with the development of warehouse layout design algorithm. In the developed model, receiving/outgoing areas, storage areas, picking/distribution areas, value-added operation areas and support areas are considered. For more efficient use of the warehouse floor space, a mezzanine floor is also considered. We develop heuristic algorithms of warehouse layout design for several cases: three types of warehouse and three types of flow. This study is expected to be used as a guideline in warehouse layout design phase.

  • A problem of relevant interest to some industries is that of the optimum two-dimensional layout. In this problem, one is given a number of rectangular sheets and an order for a specified number of each of certain types of two-dimensional regular and irregular shapes. The aim is to cut the shapes out of the sheets in such a way as to minimize the amount of waste produced. In this paper, we propose a genetic algorithms using rotation parameters by which the best pattern of layout is found.

  • This paper describes the implementation of a layout generation system for the gate matrix style to implement multi-level logic. To achieve improved layouts from general net lists, the proposed system performs flexible net binding for series nets. Also the system reassings gates by the heuristic information that shorter net lengths are better for the track minimization. By track minimizing with subdividing layout column information, the system decreases the number of necessary layout tracks. Experimental results show that the system generates more area-reduced (approximately 7.46%) layouts than those by previous gate matrix generation systems using net list inputs.

  • A computer method is developed for group technology layout and its simulation analysis. The method is composed of three phases: Phase I sorts the parts by its similar production routes and forms part families. Phase II plots the layout by machine cell and evaluates the group layout alternatives by the total process time analysis and the part travel distance evaluation analysis. Phase III also evaluates the alternatives by simulation analysis using SIMAN simulation software. All the computer programs are developed with BASIC except SIMAN simulation.

  • Purpose - The purpose of this paper is to find out the effect of changes in the differentiated "servicescape" on the business performance in the hair salon industry using a case study. For this, we selected hair salon M located in Suwon. The shop is innovatively different from existing shops in terms of spatial layout and functionality. We conducted in-depth research, beginning with the launch of the shop concept through investment and ongoing stable sales. Research design, data, and methodology - The M hair salon is a start up shop providing a differentiated servicescape (physical environment where the service takes place) located in Suwon, Yeongtong-gu. We conducted research to investigate how spatial layout and functionality of the servicescape impact customers' perceived quality. The interview period and case analysis was May 2014 through March 2015, covering 11 months. To conduct the case analysis, we analyzed the spatial layout and functionality of existing shops and interviewed customers and experts about the difference between hair salon M and existing shops. Results - Our results found clues to the positive effect of spatial layout and functionality among servicescape factors on perceived service quality at the salon. The shop showed a fast payback of the principal investment, growth potential in contrast to competitors near the salon, and 45 percent returning customers. The problem with the spatial layout at existing shops was that customers were aware of the way other people were looking at them, since viewing angles overlapped, therefore there was a limitation to the relationship intensity with an exclusive hair designer. In contrast, the layout of the stands at the M salon kept the number of dressing stands limited to maximize the customer's emotional response. Additionally, because of the new layout of dressing stands hiding other customer voices and appearance in the salon, customers perceived their service space as independent. Therefore, they did not have to focus on their personal emotional response, which was one of the advantages of the new layout. Conclusions - This study conducted case study analysis by offering a new perspective focusing on spatial layout, previously not considered as an independent variable of quality evaluations and customer satisfaction in existing literature on hair salon management. Therefore, this study contributes to the field by offering an opportunity to discover the causal relationships between the overlooked physical environment and a customer's perceived quality. However, a process objectifying the results of the study through empirical analysis and hypotheses is needed to overcome the limitations of the case study approach and generalize the results. Moreover, it would be beneficial to conduct further empirical study of the relationship between the spatial layout provided in the case and a customer's emotional response and change in mood. In addition, an analysis is needed regarding how customers feel about the factors using the Kano Model. These suggestions would be considered in further study.

  • Since 2009 of global financial crisis, shipbuilding industry has undergone hard times seriously. After such a long depression, the latest global shipping market index shows that the economic recovery of global shipbuilding market is underway. Especially, nations with enormous resources are going to increase their productivity or expanding their shipyards to accommodate a large amount of orders expected in the near future. However, few commercial projects have been carried out for the practical shipyard layout designs even though those can be good commercial opportunities for shipbuilding engineers. Shipbuilding starts with a shipyard construction with a large scale investment initially. Shipyard design and the equipment layout problem, which is directly linked to the productivity of ship production, is an important issue in the production planning of mass production of ships. In many cases, shipbuilding yard design has relied on the experience of the internal engineer, resulting in sporadic and poorly organized processes. Consequently, economic losses and the trial and error involved in such a design process are inevitable problems. The starting point of shipyard construction is to design a shipyard layout. Four kinds of engineering parts required for the shipyard layout design and construction. Those are civil engineering, building engineering, utility engineering and production layout engineering. Among these parts, production layout engineering is most important because its result is used as a foundation of the other engineering parts, and also, determines the shipyard capacity in the shipyard lifecycle. In this paper, the background of shipbuilding industry is explained in terms of engineering works for the recognition of the macro trend. Nextly, preliminary design methods and related case study is introduced briefly by referencing the previous research. Lastly, the designed work of layout design is validated using the computer simulation technology.

  • 대사체학은 대사 경로 네트워크를 통해 생명 활동을 이해하고자 하는 분야로서, 대사 경로 내의 흐름을 한 눈에 알 수 있도록 가시화하여 보여 주는 도구가 반드시 필요하다. 이러한 가시화 도구의 경우 노드수가 증가할수록 에지 교차가 기하급수적으로 증가하는 문제가 있다. 따라서 유전체 수준의 대사경로를 연구하기 위해서는 대사 경로 그래프 레이아웃 상에 나타나는 에지 교차를 줄이는 것이 시각화의 매우 중요한 부분이다. 본 논문에서는 대사 경로의 구조적인 특징에 기반한 3차원 공간 상에 대사 경로 그래프를 레이아웃해 주는 모듈을 설계, 구현하였다. 2-계층 레이아웃을 이용하여 대사 경로 그래프를 계층적으로 레이아웃함으로써 표현영역을, 3차원으로 확장시키고 기존의 2차원 레이아웃 알고리즘 적용시 번번히 나타나는 에지 교차의 수를 감소시키는 결과를 얻었다.

  • 공간 계획 시스템(Spatial Layout Planning System)은 사용자의 요구에 따라 사각의 자원을 일정 공간 안에 할당하고 사용자의 만족도를 최대화함으로써 공간 효율성을 최적화하는 시스템이다. 공간 계획 문제는 방대한 범위의 공간을 탐색해야 하므로 시간과 공간적 측면에서 높은 복잡도(Complexity)를 갖는 문제이다. 또한 특정 영역의 수정 요구나 재설계 요구와 같은 사용자의 동적인 요구 사항들을 수용할 수도 있어야 한다. 본 논문에서는 CSP(Constraint Satisfaction Problems) 해결 기법 기반의 자원 할당법을 이용함으로써 효과적으로 공간 계획 문제를 해결할 수 있도록 하였으며 사용자의 요구에 따라 변화되는 제약조건은 지능형 사용자 인터페이스 모델을 통해 좀 더 향상된 결과가 도출될 수 있도록 설계 및 구현하였다. 또한, 2차원 도면에서의 수정 요구에 대한 편이성과 시각적 검증을 위해 웹 환경 하에서의 VRML(Virtual Reality Modeling Language)을 이용한 3차원 도면을 보여준다.
