This paper presents the development of an Intelligent Cavity Layout Design System (ICLDS) for multiple cavity injection moulds. The system is intended to assist mould designers in cavity layout design at concept design stage. The complexities and principles of cavity layout design as well as various dependencies in injection mould design are introduced. The knowledge in cavity layout design is summarized and classified. The functionality, the overall structure and general process of ICLDS are explained. The paper also discusses such issues as knowledge representation and case-based reasoning used in the development of the system. The functionality of the system is illustrated with an example of cavity layout design problem.

In this study, a method that can objectively and systematically design the layout of user interface components was developed. In order to explain its application method, the method was applied to the layout design of facsimile. In particular, in order to validate the suitability of the method, comparison tests were performed for the case of facsimile. Computer simulators for layout design were made using Micromedia Flash and comparison evaluation for an existing layout and a new layout was performed in three aspects. The first comparison method was to measure and compare its movement distance when carrying out a task in two layout models. The second one was to measure and compare users' performance. The last one was to measure and compare users' subjective satisfaction after using two models. As the result, new layout design was better than the existing design in all comparison tests. The movement distance of the new layout design model was shorter than the existing model. And, its performance including task completion time and error frequency was better and users' satisfaction was higher than the existing. In conclusion, the method that was developed in this study can be very effectively used in the layout design of user interface components.

To ensure that the production system of a factory is efficient, the factory layout design should consider the location and material flow plans of facilities, workshops, and storage areas. Highly productive factories need to have an optimized layout planning process, and a customized design methodology of the production system is a necessity for feasible layout planning. This paper presents a method for designing a layout module's size and shape and provides a heuristic location-allocation algorithm for the modules. The method is implemented and validated using a rich internet application-based platform. The layout design method is based on the leisure ship production process; this method can be used for designing the layout of a new factory or remodeling an existing factory and its production system. In contrast to existing layout methods, the inputs required for the proposed method, such as target products, production processes, and human-resource plans, are simple. This layout design method provides a useful solution for the initial stage of factory design.

It is important factor to design the strip layout drawing according to product properties in press die design. Press dies are important processes in production such as a car component, house electronics, computer parts etc. In this paper, the strip layout of parts was designed for transfer dies. Results of this study can be modify the punch, trim position and notching shapes of strip layout. Utilization ratio was 70.3% by conducting piercing and notching for scrap design and materials were arranged with wide width of blank layout.

In this paper, a method to apply the simulated annealing method to three dimensional layout design problem which has multiple constraint conditions and evaluation criteria, was suggested. A program to support three dimensional layout design was developed according to the suggested method. This program was applied to the layout design of the wireless unmaned ocean space submergible boat. The layout result was improved 19.0% for the result of layout design expert. By this, it was verified that the suggested method has validity in supporting three dimensional layout design problem.

The layout design of component plays an important role in the design and usability of many engineering products. The Engineering artifacts of today are becoming increasingly complicated. The simulated annealing method has been applied effectively to the layout and packing problems of wafer. The main characteristics of simulated annealing method is that an optimum can be obtained from the many local optimums by controlling the temperature and introducing the statistic flickering. The objective of this study is to suggest a method to apply the simulated annealing method to the three dimensional layout design of submergible boat which has multiple constraint conditions and evaluation criteria. We describe an approach to define cost function, constraints and generate layouts using a computer. In this research three dimensional LAYout Design Optimization Program(LAYDOP ver.2) has been developed. The layout result(the total value of evaluation criteria) designed by a human layout expert has been improved by 31.0% using this program.

A layout design of an excavator front is a coupled design. Parameters of the layout design are coupled each other. So it is difficult to make decisions to set the parameters of the layout of an excavator front. We analyze the parameters of the layout design of an excavator front. We regroup the parameters as interface groups. And we suggest a new design process which is based on the interface groups. And we redesign user-interfaces of the Knowledge based Excavator Design System(KEDS).

본 연구는 웹 디자인에서 배색(color combination)과 레이아웃(layout)에 의한 감성 효과를 알아보기 위하여 수행되었다. 본 연구에서는 여덟 가지 배색 샘플(sample)과 네 가지 기본 레이아웃(layout)을 선정하여, 그 조합으로 웹 페이지를 디자인하여 배색과 레이아웃 타입에 따른 감성 효과를 알아보았다. 배색과 레이아웃에 의한 감성 효과는 '밝고 소프트하고 화려한' 배색과 레이아웃 타입에서 '밝다, 환하다, 간단하다, 따뜻하다, 간결하다, 소프트하다' 가 주 감성 효과로 나타났다. 그리고 '어둡고 딱딱하며 간단한' 배색과 레이아웃 타입에서는 '차갑다, 칙칙하다, 어둡다, 딱딱하다, 도회적이다'의 감성 효과가 나타났다. 또, 배색에 의한 감성 효과는 배색의 감성을 포함하고 있는 감성 어휘들이 우선적으로 나타난 것으로 보아 배색에서부터 오는 감성 효과가 크다고 해석되었다. 또한 레이아웃에 의한 감성 효과는 레이아웃 A와 B에서 C와 D타입으로 갈수록 즉, 레이아웃이 복잡해질수록 '화려하고 도회적인' 인상을 받는 것으로 나타났다. 배색에 의한 감성 효과가 레이아웃에 의한 감성효과보다 크게 나타났으나 배색은 레이아웃에 의해 이루어지므로 레이아웃에 의한 감성 효과도 중요한 것으로 해석되었다.

The purpose of this study is to propose a facility layout design algorithm based on artificial intelligence concept, and then to develop a computer program which is more practical than any other conventional facility layout design systems. The algorithm is composed of five step layout procedures; knowledge and data input, knowledge interpretation, priority determination, inference of layout design, and evaluation, In the step of priority determination, the algorithm is divided into single row and multi row layout problem. In the step of inference of layout design, alternatives are generated by constraints-directed reasoning and depth first search method based on artificial intelligence concept. Alternatives are evaluated by the moving cost and relationship value by interactive man-machine interface in the step of evaluation. As a case study, analytical considerations over conventional programs such as CRAFT and CORELAP was investigated and compared with algorithm propsed in this study. The proposed algorithm in this study will give useful practical tool for layout planner. The computer progran was written in C language for IBM PC-AT.
