Many researches and projects are actively implemented in the academic world and industrial world in order to increase the productivity through changing utility layout. Effective layout makes the flow of parts and products go on wheels and helps labor forces and utilities to be used efficiently. In this study, we looked at effect on utility layout change through a case of a company making a fuel tank of vehicle in Korea. Due to the layout improvement, this company could have flowshop system on welding line, so the stock in line was decreased, checking the number of stock became easier than before and it was possible to evaluate exact cycle time per unit. Through not only confirming qualitative effect, but also checking quantitative effect such as UPH(Unit per Hour), we obtained the conclusion that the layout improvement increased the productivity.

This paper deals with a case study of layout design and improvement in medium and small-sized manufacturing factories. The shop layout affects greatly the productivity of manufacturing systems and we introduce some cases in which shop layouts are changed to improve the productivity step by step. Based on case studies, we propose also some guides to improve and design the shop layout in medium and small-sized manufacturing factories.

The nesting of two-dimensional patterns onto a given raw sheet has applications in a number industries. It is a common problem often faced by designers in the shipbuilding, garment making, blanking die design, glass and wood industries. This paper presents a multi-stage layout approach for nesting two-dimensional patterns by using artificial intelligence techniques with a relatively short computation time. The raw material with irregular boundaries and internal defects which must be considered in various cases of nesting was also investigated in this study. The proposed nesting approach consists of two stages : initial layout stage and layout improvement stage. The initial layout configuration is achieved by the self-organizing assisted layout(SOAL) algorithm while in the layout improvement stage, the simulated annealing(SA) is adopted for a finer optimization.

Construction robot-based automation can contribute to productivity and quality improvement by replacing manpower in tasks that have simple repetitive properties or require high precision. In this respect, layout work is one of the most effective tasks in introducing robot-based automation technology. The development of a robotic layout system for building structures has recently been promoted in Korea, and a prototype of a marking robot has been produced. However, for commercialization, the technology improvement is required through the analysis of major improvement directions. Therefore, this study aims to derive the improvement priorities of the marking robot based on the evaluation of researchers who participated in the development process. As a result, there was a high demand for improvement in factors such as the robot's precise positioning method and robot size and weight. The results of this study are expected to serve as guidelines for the efficient input of limited resources in the future technology development process.

This paper deals with a case study on the process improvement and the layout design of a boiler factory with FactoryCAD. Firstly, two alternatives of job reallocation are suggested with the understanding of problems in current process. The layout planning for these new alternatives is carried out by simple procedure and the detailed analyses are performed by the aid of FactoryCAD program. The result shows that the new layout plan brings on about 10% reduction of travel distance. The utilization of FactoryCAD program can simplify the process of layout design.

This paper is written to analyze systematically the varieties of informations about cooking stream procedure on the basis of the basic theory of installation and arrangement such as SLP(Systemic Layout Planning) and to deduce the plan for the device, installation and arrangement suitable to cooking stream procedure. Through the substantial improvement in the modeling of hotel L, the optimization of the capacity of installation and arrangement, and the reduction of food resource stream and its movement and through the analysis of cooking stream procedure by disposing and dividing the main kitchen into three individual ones, the improvement of productivity in comprehensive cookery such as the specialization and equalization of cooking procedure and improvement effect of the price-reduction. Moreover, as for the problem of arrangement of installation, it was displayed that the effect went up to twice through the flexible production-related systems such as the improvement of arrangement, reduction of cooking preparation time, the standardization of cookery.

The objective of this study is to develop an improved algorithm for layout problems. Computerized facility layout program was also applied to solve the layout problem in locomotive maintenance workshop. The current facility layout is structured in the large space without considerations of many variable factors. For this reason, effectiveness of layout results in loss on effective space utility. This study is to develop an algorithm in the consideration of importance weight and desirable shape of specific department in the computerized layout planning and quantitative relationship rating between each department was used. Standard process duration of locomotive maintenance workshop was used to select the main activities of locomotive maintenance work. This study could generate more efficient facility layout design to reduce the number of movement frequency and travel distance in maintenance workshop.

This study is consists of two parts. First, we analyzed two construction algorithms; CORELAP( Computerized Relationship Layout Planning) and ALDEP (Automated Layout Design Program). And we made a New Relationship Layout Planning overcoming the defaults of CORELAP and ALDEP. Second, we described the only improvement algorithm CRAFT(Computerized Relative Allocation of Facilities Technique). And we modified the CRAFT, which is considering the economic evaluation.

이 연구에서는 주어진 공장의 공간에 여러 개의 직사각형 형태 부서의 위치를 할당하고 문헌에 있는 다른 설비배치 기법과 비교하고자 한다. 이 연구는 초기 설비배치가 주어졌을 때 물류비용을 최소화하는 개선적 접근방법을 제시하였다. 기존의 문헌에 있는 접근 방법과 같이 이 연구에서 제시된 접근 방법도 하나의 설비배치에서 부서를 교환하여 더 좋은 해를 찾고자 하였으며, 물류비용을 개선하는 자기발견적 절차를 적용하였다. 수직적 교환, 수평적 교환, 통합 절차 및 분리 절차를 통해 더 좋은 해를 발견할 가능성을 높이고 크기가 같은 설비의 경우에는 설비 배치의 회전도 가능하게 하였다. 그러나 CRAFT와 달리 이 연구에서 제시되는 알고리즘은 설비 형태의 왜곡이 일어나지 않고 직사각형을 유지하는 좋은 해를 제공한다. 또한 Tabu 탐색기법을 활용하여 지역적인 최적해에서 전체 최적해를 찾아가고자 하였다. 문헌에 있는 25개의 설비배치 문제에 대하여 다른 접근 방법과 비교한 결과 제시된 접근방법이 설비의 수가 많을 때 훨씬 더 좋은 해를 제공하는 것으로 나타났다.
