  • 인류의 역사가 시작된 이후, 인간의 창조는 자연의 모방이라는 큰 울타리 안에서 이루어져 왔다. 신의 작품이 위대한 자연이라면, 인간의 작품은 극히 단순한 그것의 모방에 불과한 것인데, 인간은 인간의 제한된 두뇌 활동으로 이해하기가 불가능한 복잡한 자연을 인식하기 위하여 단순화(simplification)라는 방법을 사용하여 왔다. 이 과정에서 기하학(geometry)은 극도로 발전하게 되며, 인간의 자연 인식을 위한 보편적인 수단으로 자리잡게 된다. 중요한 사실은 기하학이 수단으로서 뿐만 아니라 인간에 의한 창조의 목표로서 위치하게 되었다는 사실이다. 즉 기하학은 자연의 모방이전에 이미 인간의 상상력을 지배해왔고, 그것은 가장 보편적인 창조원리가 되어왔다는 점이다. 그러나 최근의 과학과 기술의 발전, 특히 컴퓨터 기술의 발전으로 그 복잡한 자연은 단순화의 과정을 거치지 않은 복잡한(complex) 상태로 인간에게 이해되어지기 시작했다. 그중 하나가 19세기에 시작된 복잡성(chaos)이론인데 실내공간의 디자인에 있어서도 이러한 자연의 복잡성(complexity)이 새로운 창조 원리로서 자리잡게 되었다. 대표적인 실내 공간 다지이너로서 Nigel Coats를 꼽을 수 가 있는데 그의 무정부적인 (anarchism) 디자인 성향은 자연에서 발견될 수 있는 특징중의 하나라고 할 수 있다. 그가 추구한 복잡성(complexity)은 일본의 동경과 같은 고 밀도(high density)의 적극적 소비 도시(active consuming city)에서 발견되는 지극히 인간적인 도시생활을 만들기 위한 software의 제작이며, 이는 자연이라는 신의 창조물에 근접한 모방이 된다. 본 연구는 Nigel Coats의 작품에서 발견될 수 있는 이러한 무정부주의적 성향이 어떻게 자연의 본질적인 복잡한 (complex) 모습과 관련이 되는가를 통하여 현대 실내디자인의 새로운 방향이 이 시대의 과학적 발견에 따른 복잡성(complexity)과 유관함을 보여준다.

  • Complexity metrics have been developed for the structured paradigm of software development are not suitable for use with the object-oriented(OO) paradigm, because they do not support key object-oriented concepts such as inheritance, polymorphism. message passing and encapsulation. There are many researches on OO software metrics such as program complexity or design metrics. But metrics measuring the complexity of classes at the OO analysis phase are needed because they provide earlier feedback to the development project. and earlier feedback means more effective developing and less costly maintenance. In this paper, we propose the new metrics to measure the complexity of analysis classes which draw out in the analysis based on RUP(Rational Unified Process). By the collaboration complexity, is denoted by CC, we mean the maximum number of the collaborations can be achieved with each of the collaborator and determine the potential complexity. And the interface complexity, is denoted by IC, shows the difficulty related to understand the interface of collaborators each other. We verify theoretically the suggested metrics for Weyuker's nine properties. Moreover, we show the computation results for analysis classes of the system which automatically respond to questions of the user using the text mining technique. As a result of the comparison of CC and CBO and WMC suggested by Chidamber and Kemerer, the class that have highly the proposed metric value maintain the high complexity at the design phase too. And the complexity can be represented by CC and IC more than CBO and WMC. We can expect that our metrics may provide us the earlier feedback and hence possible to predict the efforts, costs and time required to remainder processes. As a result, we expect to develop the cost-effective OO software by reviewing the complexity of analysis classes in the first stage of SDLC(Software Development Life Cycle).

  • In many practical engineering design problems, there are some design and manufacturing considerations that are difficult or infeasible to express in terms of an objective function or a constraint. In this situation, a set of optimal candidate designs having different topological complexities, not just a single optimal design, is preferred. To generate systematically such design candidates, we propose a hierarchical multiscale design resolution control scheme. In order to adjust its topological complexity by choosing a different starting resolution level in the hierarchical design space, we propose to employ a general M-band wavelet transform in transforming the original design space into the multiscale design space.

  • As important elements consisting of city streetscape, facade design on building is generally very significant. But without active acceptance and understanding of the concept that the building has a private objective as personal property, it is not easy to take an involvement into design as well as to establish reasonable and scientific standards of harmony. Therefore, for desirable streetscape planning, it is indispensable to know how to closely examine the visual harmony of already established buildings in each street and how to get the solutions for its realization. In this respect, this study is to try to examine and verify the feasibility of our present streetscape situation by experimental application of acceptable Y. Elesheshtawy's model(1997), an interpretation of quantitative index of street buildings by Gestalt theory, for the preparation of the foundation of institute and standards of building design which has social value in contributing to visual and spacious harmony in our street space without giving any damage to private property. From the result, I can assure the validity that the physical complexity, whose schema is socially and culturally different from our reality, is applicable to our actual streetscape in some extent.

  • Modern engineering design problems involve complexity of disciplinary coupling and difficulty of problem formulation. Multidisciplinary design optimization can overcome the complexity and design optimization software or frameworks can lessen the difficulty. Recently, a growing number of new multidisciplinary design optimization techniques have been proposed. However, each technique has its own pros and cons and it is hard to predict a priori which technique is more efficient than others for a specific problem. In this study, a software system has been developed to directly solve MDO problems with minimal input required. Since the system is based on MATLAB, it can exploit the optimization toolbox which is already developed and proven to be effective and robust. The framework is devised to change an MDO technique to another as the optimization goes on and it is called a reconfigurable MDO framework. Several numerical examples are shown to prove the validity of the reconfiguration idea and its effectiveness.

  • Warehouse planning or design is not a static, one-time activity. To survive in the constantly changing market warehouse design should be a continuous process in which the anticipated requirment are reflected on the current warehouse status. Thus, the goal of warehouse management is to effectively utilize the various warehouse resources to meet the varying customer requirment. This paper presents an engineering framework for warehousing system analysis and design from the perspective of a total system approach. The complexity pertinent to warehousing system analysis and design is first discussed, which mainly come from the interplay among product data, order data, equipment types, operating strategies, and functional specification of the overall system. The understanding of the complexity leads to a general structure and a conceptual design procedure for a warehousing system. The general structure is comprehensive enough to represent most warehousing and flexible enough to accommodate the more sophisticated ones. The conceptual design procedure portrays the high-level interelationships the design issues.

  • The purpose of this study is to apply a concept of open structure to clothing design and to verify the characteristics found in the various types of clothing which has open structure. The literatures from various academic fields including philosophy, literature, social science, architecture, and fine arts are investigated to define the concept of openness and to analyze it from the perspectives both of the visual and of the moaning of openness. This paper is to identify the types and the characteristics of clothing by future intention, complexity, discontinuity of open structure. By closely examining fashion design after 1980s found in fashion collection publications and designer's websites, the results of this study are as follows: first, the concept of openness can be classified into two different levels, that is, visual and meaning, secondly, in clothing the concept of open structure is applied to the meaning side by future intention, by complexity and by discontinuity. Open structure through future Intention has new content and interpretation and must have the possibility of intelligence awakening, future guidance and basic contents. Open structure through complexity has secondary function exists concurrent with the shape key example is the smart clothes with the digital functions. It has functions of amusement, supplement and protective, and is future clothes which satisfies with health, welfare, desire of beauty. Open structure with discontinuity is clothes with dramatic changes in system, structures and states. Structure can be changed by silhouette, detail, or fabric, material, or dramatic and practical function as tools in terms of productions and environment. This study can help to formulate and to integrate the concept of open structure in clothing with various phases and enhance the value of clothes by showing an application of the concept of openness to the clothing in meaning level.
