The corporate environmental management system shall be essential for most of the firms in this planet. Korean firms also cannot avoid this trends. However, under recent economic conditions ruled by International Monetary Fund, Korean business managers seem to lower the priorities of environmental issues in their business decisions due to the financial pressure, so that the investments in developing environmental management system be slowed down. In the meanwhile, in light of competence of environmental management system, Korean firms have little experiences and are lack of basic knowledges and know-hows relative to those of developed countries. The ISO14001 EMS(Environmental Management System) is a voluntary standards which is expected to be a worldwide business requirement near future. It is designed not only to help a systematic implementation of any organization’s specific EMS, but also, through continuous improvement process, to enable it to facilitate system learning. In this paper, we first investigate several issues of ISO14000 standards in relation to the meaning of its certifications for Korean firms and then suggest a model for developing an EMS utilizing the basic ISO 14001 EMS principles. The suggested model could be expected to help create a system learning and can be a useful framework to make a long-term investment strategy, so that Korean managers could take it easy to handle and involve in environmental problems.

Recent developments in AITSs(Advanced Information and Communication Technologres) are generally expected to enhance our quality of life and economic efficiency in the era of information society. However, if not handled properly, there may also be negative effects such as the problems of social exclusion, degradation of privacy and security, and some cultural and/or ethical problems, due to the high speed and wide scope of the socio-economic changes. In this paper, we first review and categorize these negative functions into four main categories: socio-economic effects, those effects negatively affecting the demand and supply of AITSs, socio-cultural effects, and ethical issues. Social exclusion and universal service are main issues of the first category and the second one includes the protection of IPR(Intellectual Property Rights), privacy, and security. For each topic, current trends and future issues are analysed and alternatives are briefly discussed. Since every relevant changes are to be made from now on, our study mainly depends on the literature review of currently on-going US and European studies.

신서비스개발의 방법론에 관한 연구: 문헌고찰

성백서(Baek Seo Seong) 건국대학교 경제경영연구소 2007 商經硏究 Vol.32 No.1

This paper reviews NSD(New Service Development) literatures. Early studies on NSD proposed its NSD processes based on the NPD(New Product Development) framework developed in the manufacturing industries. In the meantime, empirical results from financial industry and IT(Information Technology) related industries indicate some differences in NSD process activities because of its special characteristics, i.e., intangibility and simultaneity of production and consumption. Two so-called “want-to-be generic” NSD process models, which resulted from that observation and on from marketing society and the other from strategy society, were reviewed with a third one which is based on the success of 6 sigma approaches in total quality management of operations society and called DFSS(Design for Six Sigm). Managerial implications in utilizing those models for service firms and future reseach and limitations are discussed.

線型計劃法을 위한 非頂邊解法의 硏究

Seong Baek Seo(成百瑞) 건국대학교 경제경영연구소 1988 상경연구 Vol.13 No.1

This study reviews the solution techniques for Linear Programs which have been proposed after the well-known Simplex method was published in 1947. One group of them are simplex-based ones that include the advanced basis technique, constraint, relaxation technique, multiple pivoting or some ad hoc relaxation called PAPA. Second are the feasible direction search types of Nonlinear Programming solution methods to Linean Programs. Besides these, the theoretical evolution of polynomial-time algorithms including the Khachiyan’s ellipsoid algorithm and the Karmarkar’s projective algorithm is notable in the literatures. As a result of reviews, we conclude that the non-edge following strategies which are common in almost all of the above studies, seems to be promising for improving the computational efficiency over the Simplex Method. We then, investigate the polynomial-time property of the projective algorithm and a feasible direction algorithm with finite convergence which is noted to be more efficient than the Simplex with limited experiences. More research efforts are required on this topic.

階層化意思決定(AHP)을 利用한 에너지/資源 技術開發 優先順位 評價模型

Seong Baek Seo(成百瑞) 건국대학교 경제경영연구소 1993 商經硏究 Vol.18 No.1

This paper presents an analytic hierarchy process(AHP) model for determining the energy/resources R & D priorities in Korea. The priority planning problem in the energy/resources R & D sector is a very complex one with multiple decision criteria such as the degree of contribution to the national energy securities, the relative economic efficiency, the possibility of R & D success, the degree of proliferation effect in national scientific/technological improvement, and the degree of effects to the recent hot issue of environmental problems, etc. We employ the AHP technique which is known to be useful for such a muti-attribut decision-making problem. We first investigate the R & D characteristics of Korean energy/resources technologies, and design a hierarchical priority evaluation system. Based on this, we develop AHP questionaires and survey over the experienced experts in two stages. The first stage is done to the experts separated by research areas such as electricity, nuclear, oil, gas, coal, renewable energies, energy saving, etc., appreciating the differences among the areas. The R & D options evaluated as that of first priority in each area are reevaluated by the energy policy experts in the second stage. The results are demonstrated selectively with the emphasis on the data manipulation method because they are not our primary concerns. The full report of the results can be found elsewhere.

국내 문구산업 공급사슬네트워크에서의 채찍효과 분석

최호영(Choi, Ho Young),성백서(Seong, Baek Seo),이정호(Lee, Joung Ho) 한국물류학회 2018 물류학회지 Vol.28 No.5

본 논문은 문구산업의 공급사슬네트워크에서 채찍효과의 원인을 실증적으로 규명하고 이를 감소시킬 수 있는 대안을 제안한 다. 기존 물류관련 문헌이 자본재 산업 중 특히 성장기 제품의 채찍효과를 수요기반 측면으로 분석하고 있는 반면, 본 논문은 보다 일반적인 소비재 산업 내 성숙기 제품의 공급사슬에서 발생하는 채찍효과의 구조적 원인을 밝히는 것을 목적으로 한다. 이를 위해 본 연구는 먼저 국내 문구산업의 공급사슬 내 기업들로부터 수집한 실제 매출 자료를 이용하여 공급사슬네트워크에서의 채찍효과를 확인하고 기존 문헌으로부터 도출한 분석틀을 적용하여 채찍효과의 4가지 원인과 대응 방안을 분석한다. 특히 본 논문은 실증적 연구방법으로써 공급사슬네트워크 내 기업의 실무 담당자들과의 심층면접을 통해 수집한 자료를 활용하여 계층적 분석 과정(AHP) 모형을 구축하고 분석함으로써, 실무자들이 고려하는 공급사슬네트워크에서 채찍효과의 중요 원인을 실증적으로 밝힌 다. 이에 따른 본 연구의 결과 소비재 산업 중 특히 성숙기 제품의 특성을 지닌 문구산업의 공급사슬네트워크에서 채찍효과의 존재를 확인할 수 있었으며, 이의 주요 원인이 기업의 정책적인 부분에 해당하는 가격변동으로 확인되었다. 이는 기존 문헌의 수요 예측의 수정이라는 연구 결과와는 대비되는 것으로 공급기반 측면에서 채찍효과를 감소시킬 수 있는 방안을 고려할 필요가 있음을 보여준다. 본 연구의 결과는 소비재 산업 특히 성숙기 제품의 공급사슬네트워크에서 공급업체의 가격 전략에 대한 새로운 가능 성을 제시하는 한편, 물류 네트워크에서 유통업체와 같이 최종 소비자와 접점을 이루는 조직이 구매 또는 판매 경로를 선택하기 위한 효과적인 방법으로 확장될 수 있다. The purpose of this study is to empirically identify the bullwhip effect on the stationery supply chain network and to propose an alternative solution to reduce it. Existing literature related to logistics analyzes the bullwhip effect of the capital goods industry, especially the products during the growth period, at the aspect of the demand base. This article, however, is focusing on structural cause of the bullwhip effect in the supply chain of more general consumer goods during the mature period. To this end, the bull whip effect in the supply chain network was confirmed using the actual sales data collected from the companies in the supply chain of the domestic stationery industry. Then the four causes and countermeasures of bullwhip effect were analyzed by applying the analysis framework derived from existing literature. In particular, this article used an empirical research method. By constructing and analyzing AHP (Analytic Hierarchy Process) model using the materials collected through in-depth interviews with working level respondents of the companies in the supply chain network, significant causes of bullwhip effect in the supply chain network were identified. As a result, it was confirmed that there was bullwhip effect in the stationery supply chain network which could be characterized as mature period goods among consumer goods. It was also confirmed that the major cause was price fluctuation falling under the division of corporate policy. The result of this study is not consistent with previous studies which addressed the demand signal processing. It showed the needs to consider the method to reduce bullwhip effect from the supply base. The results of this study suggest new possibilities for the suppliers pricing strategy for the consumer goods in the mature period in the supply chain network. It can be extended to an effective way to select a sales or marketing channel for organizations that are in contact with end consumers in the logistics network.

R&D 6시그마 導入 에 따른 新製品 開發의 成果에 관한 硏究

고두균(Doo kyun Ko),성백서(Baek Seo Seong) 건국대학교 경제경영연구소 2005 商經硏究 Vol.30 No.1

Although world best companies are adopting product development methods, which is basically based on customer needs, domestic companies seems to be lack of understanding customers’ potential needs. GE, one of the pioneer companies introducing six sigma approach in manufacturing, also initiated application of six sigma to R&D, which is called DFSS (Design For Six Sigma). In nature, DFSS has a process of combining concurrent engineering, NPD(New Product Development), and NPI(New Product Introduction), altogether. In this paper, we define a similar, but new, concept of R&D six sigma in terms of a combination of individual development process and development structure. Then, we suggest a hypothesis that R&D six sigma could have positive effects on product development performance. To prove this hypothesis, 300 manufacturing companies(home appliance, PC production oriented electronic industry and car manufacturing companies) were sampled, and surveyed. The result shows that introducing a R&D six sigma has effects on product development, and users of R&D six sigma approach could obtain better performances in their product development than non users.
