The need for holistic modeling efforts for returns that capture the extended closed loop supply chain (CLSC) system at strategic as well as operational level has been clearly recognized by the industry and academia. Strategic decision-makers need comprehensive models that can guide them in efficient decision-making to increase the profitability of the entire forward and return chain. Therefore, determination of a near optimal design configuration, which includes the environmental, economical and technological capability factors, is important in strategic decision-making effort that affect the profitability of the closed loop supply chain. In this paper, we adopted an improved system dynamics methodology to tackle strategic issues that affect various performance measures, like market, time/cost, environment etc., for closed loop supply chains. After studying real life implementation issues in CLSC design, we presented guidelines for the PBM (Participative Business Modeling) methodology and presented its extension for the strategic dynamic system modeling of return chains. Finally, we demonstrated the measurement of operational performance by extending SD (system dynamic) application to closed loop supply chain management.

AHP is a well-known multiattribute decision technique that has been applied to private and public areas. It is well suited to group decision making and offers many benefits as a synthesizing mechanism in group decisions. This paper explains why the AHP is well-suited to group decision making by means of the case study. Through this case study, this paper tried setting priorities for the strategic industry with the focus on the small and medium industry in Pusan.

This paper introduces several decision-making problems that need to be solved in order to facilitate the efficient operation of container terminals. These decision-making problems include the berth planning problem, the quay crane scheduling problem, the unload/load sequencing problem, the yard allocation problem, and the short-term scheduling of transporters and yard cranes. These problems can be classified into strategic decision problems, tactical decision problems, and real time operational decision problems. This paper proposes definitions of the problems that can be used to develop mathematical models for the problems.

Purpose - The purpose of this study is to provide a formalized process of decision making for companies or organizations that need to make various decisions in the age of uncertainty. Therefore, this study aimed to proposes a strategic decision-making approach citing the relatively easily accessible using IPA(important-performance analysis) and SWOT/AHP analysis. Research design, data, and methodology - To be specific, the first step is to derive necessary attributes and conduct IPA. The second step is to subdivide the IPA results into internal strength and weakness factors and the external opportunity and threat factors, hierarchize those factors, and weight them accordingly. The third step is to build a causality model to propose a method of supporting a rational decision making. Results - The foregoing approach seems to facilitate the diversification of decision-making strategies by helping businesses or organizations to measure and analyze the attributes needed for certain decisions. Additionally, the perceived importance and satisfaction (or achievement) usage of those derived attributes can be used as the reference data for SWOT/AHP analysis. Conclusions - The proposed stepwise approach is applicable to businesses or organizations in need of making stepwise decisions in line with their retained competencies in comparison to conventional or intuitive decision-making practices.

최근 다양한 유형의 사이버공격이 발생하였고 공격의 전략적 목적 및 전술적 수단도 진화하고 있다. 특히 한수원 사이버공격은 해킹과 심리전을 결합시킨 핵티비즘형으로 공격자는 국민을 사이버전에 참여시키려 하였고 기밀정보 공개 및 원전중단 협박으로 정부의 의사결정을 지속적으로 강요하였다. 따라서 본 논문에서는 사이버공격시 효과적 전략결정을 도출하기 위하여 개방형 정책결정모델에 공격지성을 포함시키고 게임이론을 활용하여 연구한다.

세계 각국은 지식재산권이 확보된 자국의 기술을 국제표준으로 제정하여 산업보호 및 해외시장 창출을 추구하고 있음에 따라, 우리나라도 국가 정책적 차원에서 효과적인 표준화전략을 수립하기 위해서 시장 및 이용자가 요구하는 기술 분야의 표준화 과제를 선정하고 우선순위를 정하여 선택과 집중전략을 운영하는 것이 필요하다. 표준화 분야의 우선순위를 결정하는 것은 학계, 연구계, 산업계, 정부 등의 이해관계가 존재하는 의사결정문제로 복수의 평가기준을 갖는 다기준 의사결정문제로 정의할 수 있다. 본 연구에서는 다기준 의사결정문제에 체계적인 이론과 절차를 제공하는 계층분석방법(AHP)을 이용하여 국내 민간 표준화기구인 한국정보통신기술협회에서 선정한 37개 표준화 분야에 대한 우선순위를 결정하였다.

기업의 전략적 의사결정자는 불확실성과 복잡성에 직면해왔다. 그리고 그들은 이러한 환경 하에서 의사결정을 내려야 함에도 불구하고 그들의 의사결정에 필요한 충분한 시간, 인력, 예산, 그리고 지식이 충분히 주어지지 않는다. 그래서 그들은 그 분야에 대한 암묵적 지식을 지닌 전문가들의 지원을 받는 수 밖에 없다. 그러나 의사결정자들이 어떤 문제에 직면할 때 마다 의사결정에 필요한 새로운 지식을 창조하고 변형하고 결합하고 응용하는 다른 절차나 방법을 발견하는 것은 매우 어렵다. 본 논문은 노나카에 의해 제안된 지식변환과정을 이용함으로써 전략적 의사결정을 지원할 새로운 방법을 제안한다. 본 연구는 컨설팅 산업분야에서 전략적 의사결정의 응용사례를 예시한다. 이 논문은 제안된 방법에 기초한 의사결정지원기법으로서 인지지도를 사용한다.

과거에는 경영의사결정에 적절한 정보를 적시에 제공할 수 없기 때문에 불확실한 경영을 했으며 경영자는 주관적인 경험과 판단 등에 의지하였다. 정보기술의 발달과 더불어 발전한 정보시스템과 기술은 비즈니스 운영면에서 고도의 효율성과 생산성을 달성하기 위하여 관리자가 활용할 수 있는 가장 중요한 도구 중에 속한다. 이것의 효과는 비즈니스 실무와 관리행태의 변화가 동반되었을때 더욱 크게 나타난다. 본 연구에서는 기업의 전략적 의사결정에 필요한 문제를 해결하기 위하여 정보기술을 활용하여 필요한 정보를 획득하고 문제해결 방법론을 시뮬레이션 하여 객관적이고 정형화된 경영의사결정을 지원하는 시스템을 개발하기위한 기능요소 및 솔루션을 구조화하였다. 본 연구에서 제안하는 전략의사결정지원 시스템은 기업경영 지원기술에 관련된 것으로 IT기술을 활용하여 경영의사결정에서 요구되는 전략의사결정 문제에 있어서 최적의 시나리오를 선택하도록 하여 신뢰성 있는 기업경영에 도움을 줄 수 있는 시스템이다. 전략의사결정시스템은 개별사업 시뮬레이션과 전사사업 시뮬레이션, 전사사업 포트폴리오 관리 등 크게 세 가지 기능부문으로 나누어 볼 수 있다. 본 시스템은 객관적이고 정형화된 컨설팅 결과를 제공함으로써 신뢰성을 보장할 수 있고, 급변하는 경영 여건에 효율적으로 대응할 수 있는 유용한 효과를 기대할 수 있다.

We have used various information technologies (IT) in group decision-making for increasing effectiveness and satisfaction of group decision-making process. Recently, a new form of IT so called Group Decision supprot System (GDSS) was introduced into group decision-making process. Previous experimental studies about effectiveness of GDSSS have been inconsistent and the results were mixed. There was no empirical studies about GDSS in Korea. In this study, we divide two groups-GDSS supported group and traditional face-to-face group and investigate impacts of GDSS on group decision-making processes and outcomes. An idea generation task for operational action plan development, implementing GEO's strategic vision, served as the decision-making context. Supported GDSS is GroupSystems V, which had been developed by Univ. of Arizona. It was translated by Korean. According to the results, Number of nonredundant ideas in GDSS group is two or three times more than Non-GDSS grop. GDSS group feel more equal status, have better interpersonal relationship, have more confidence on group decision than Non-GDSS group. But satisfaction of participants on decision-making process and outcome has not showed a significant difference between two groups. Because all of participants in GDSS group were novice to GDSS. With this results we suggest further studies on transforming western type GDSS to Korean decision-making culture. It will be cornerstone for development of GDSS in Korean desision-making culture. It will be cornerstone for devlopment of GDSS in Korean decsion making culture environment.

As the world's attention turns to sustainability and the considerations of cumulative effects, the concept of Strategic Environmental Assessment(SEA) has become more significant and urgent and increasing number of countries and international organizations now undertake some forms of SEA. The term SEA, however, is variously defined and understood; generally it means a formal process of systematic analysis of the environmental effects on development policies, plans, programmes and other proposed strategic actions. This process extends the aims and principles of EIA upstream in the decision-making process, beyond the project level in which major alternatives are still open. There is a shift toward more integrative approaches and greater use of Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) as sustainability tools in cooperation with Environmental Management System (EMS). Currently, Korea has EIA system and Prior Environmental Review System (PERS) which is different type of SEA as Environment Assessment (EA) system. APEMI IA MODEL integrated following three pillar(refer to attached figure.1) ; First pillar symbolized decision making cycle with planning process. Second pillar symbolized integrated assessment which tying SEA and EIA with specific impacts assessment(eg: social impact assessment, economic impact assessment, health impact assessment etc) in cooperation with EMS. Third pillar symbolized EA best practical procedure of International Association for Impact Assessment(IAIA). Considering the above, we applied new conceptual model(APEMI IA MODEL) into Impact Assessment for better integrated decision-making in KOREA as an alternative IA system(IS IA MODEL A and B refer to attached figure 4, 5).
