Spatial decision support systems(SDffi), a new class of decision support system(DSS), result from the melding together of GIS and DSS, Planning support systems(PS5) add more advanced spatial analysis functions than GIS and intertemporal functions to the functions of SDSS. This paper reports the development of a planning support system providing a framework that facilitates urban planners and civil engineers in conducting coherent deliberations about the generation of satisficing sewers. 1he planning support system for the generation of satisficing sewers(PS5/GSS) was designed from the understanding that land use and development drive the demand for storm and sanitary sewers. Through four stages of supply, demand, alternative generation, and evaluation, PSS/GSS integrates basic planning, preliminary design, and engineering design of sewer. GIS and graphic user interface are excellent toolboxes for designing sewer networks, estimating the quantity of wastewater, and showing generated alternative sewers. A sewer model using simulation tedmique can generate an initial sewer. Users can define alternative sewers by the direct manipulation of sewer networks or by the manipulation of parameters in the sewer model. The sewer model evaluates the performance of the user defined alternatives.

Group Decision Support System(GDSS) has been a rapidly emerging field of the 1990's. Whereas conventional Decision Support System(DSS) helps individual decision makers, GDSS are designed to help groups of senior management and professional groups reach consensus. However, empirical researches which required to establish the optimum GDSS specification are scarce. Along with this purpose, this paper was focused to investigate the effect of group decision factors on the efficiency of the group decision. In this paper, task types of group decision which were discussed as major variable at many papers were settled as environmental factor. The result has verified the importance of the role-related factors on the efficiency of the group decision. This fact highlights the need of more researches on the role-related factors in the group decision in the GDSS development.

의사결정자 지원은 문제 인식, 대안 생성, 최적안 선정 등 협의의 의사결정 지원시스템 (Decision Support System, DSS) 뿐 아니라 의사결정자의 일상업무지원과 의사결정 능력 향상을 위한 교육을 포함한다. 본 논문의 목적은 의사결정자를 지워하기 위한 일종의 광의의 의사결정 지원 시스템인 의사결정자 지원시스템(Decision Maker Support System, DMSS)에 대한 개념적 틀을 제시하는 것이다. DMSS는 전통적인 의사 결정 지원시스템, 업무처리 시스템, 가상교육 시스템 및 이들을 통합 관리하여 특정 의사결정자의 요구에 맞게 구성해 주는 DMSS 관리자를 핵심 요소로 하며 원격의 의사결정자 존재를 생각하여 사용자 인터페이스는 웹 기반을 고려하였다. 특히 DMSS의 하위 시스템의 지식을 통합하기 위해 일원화된 지식베이스를 설계하였다. 그리고 DMSS의 가능성을 보이기 위해 가상 시나리오를 통해 설명하였다.

This paper develops a new approach to dealing with qualitative reasoning processes involved in managerial decisions, drawing upon choice strategies that have been developed within the general framework of multi-criteria decision making. Issues such as choices under uncertainty and preference formulation are addressed. An MCDM DSS intended to assist in high-level management decisions must focus on helping the decision maker to properly define the problem by providing a structure to it and to dynamically evaluate the alternative courses of action. A conceptual architecture is developed and presented to propose a general model for designing decision support systems specifically designed to assist in MCDM in a managerial context. A commercial loan approval judgment case is described to illustrate the real-world situation where decisions are made under fuzziness and usually require a high degree of intuition and subjective judgment. Development of a prototype system intended to partially represent application of the architecture is described.

Over the last decades, interest in the application of decision support systems (DSS) in organizations has increased rapidly. Despite the growing number of investigations exmaining decision support system, relatively few empirical studies have evaluated the effects of DSS on problem-solving processes. This study examined, using a computer simulation technique, the effects of recursion in problem-solving processes on the problem-solving time. Results indicate that the recursions at the early stage of problem-solving processes scarcely influenced the problem-solving time, which is contrasted with the case of the recursions at the final stage.

This paper deals with the case analysis of second order processes under sampled-data. Proportional Integral-Derivative(PID) control, and development of Decision Support Systems(DSS) for such processes. In this paper three techniques were described for identifying the dynamics of closed loop stable processes. The first, called pulse testing is a frequency-domain method, which yields the frequency response diagram of an open loop process. The second is a time-domain method which yields the gain and time constants of the process model. The third technique is based on step response and gives the parameters of PID controllers. The development of DSS design programs consisting of above three techniques will provide very powerful tools in the microcomputer based process control.

In this paper, a new method of product function analysis is presented to categorize various design information generated in product development processes. In order to improve product functions, designers must understand unit functions and modified parts of products. The product function analysis (PFA) is based on the designer's understanding of product functions. The proposed PFA provides the methodology to classify the various functions systematically and understand the relation between functions easily. Using this approach, efficient design support system can be developed and used for designers to support decision-making with design knowledge.

경영 교육의 도구로서 경영 모의 게임(Business Simulation Game)이 널리 활용되고 있다. 최근에는 BSG의 교육 효과를 높이기 위해서 BSG를 위한 의사결정지원시스템(Decision Support System)을 개발되고있다. 반면에 국내에서는 BSG와 같은 경영 교육 도구가 부족할 뿐만 아니라 DSS 기능을 가진 BSG는 전무한 실정이다. 따라서 본 연구에서는 경영 전략, 마케팅, 생산, 재무 영역을 포함한 한 BSG의 교육 효과를 높이기 위한 DSS prototype을 개발하였다.

의사결정지원시스템(DSS: Decision Support System)은 비ㆍ반구조적 문제의 해결에 있어서, 의사결정의 각 단계 혹은 전과정에 걸쳐 의사결정자를 지원함으로써 의사결정의 효과성을 증대시킬 수 있도록 설계된 컴퓨터 기반 시스템이다(Scott Morton, M. S., 1971). 지금까지 많은 의사결정지원시스템이 제조생산, 금융, 비즈니스 등 다양한 분야에 적용되어 왔으며, 개인 및 집단의 의사결정의 효율성 및 효과성 제고에 많은 기여를 하였다(Holsapple and Whinston, 1996).(중략)

In the modern society where information system based on the computer in organization have been developed over again. A decision support system is one of the most popular topics. The computer have been discussed in relation to management strategy between enterprisers and researchers so far, but the accumulation of data resource and communication foundation have not been attended in actuality. The organic connection between business and information technique have been less progressed than our expectation. At this point of time. such a technical restrution getting removed, We have closed a gap between management strategy and computer. Now we are taking a growing interest in computer use for supporting proceedings decision, a lot of strategic marketing decision is wifely used in such a case, and the technical development is comming to advanced. In this study, I Investigate such a new tendency as strategic program and proceedings decision system. I will especially focus my study on a strategic program and a budget control corporation, so to speak, on strategic budget management system. Concretely the purpose of this study is to investigate what functions the proceedings decision support system requires in order to deal with the problem of strategic level and to practically establish the system with the use of DSS GENERATOR/ARISTOTLE in my laboratory.
