신제품 개발의 성능 향상, 개발기간, 자원 투입 및 가격 결정을 위한 통합 모델
편제범(Jebum Pyun),김대수(DaeSoo Kim),박명섭(Myungsub Park) 한국생산관리학회 2012 韓國生産管理學會誌 Vol.23 No.4
신제품 개발에 관한 의사결정은 기업이 제한된 시간적 공간에서 한정된 자원을 효율적으로 활용하여 이익을 창출하기 위한 필수 사안으로 기업의 존속과 성장에 매우 중요한 영향을 미친다. 최근 산업의 글로벌화로 인한 경쟁의 심화와 더불어 고객의 요구와 선호도가 다양해짐에 따라 제품의 수명주기가 점점 짧아지면서 신속하고 통합적인 신제품 개발의 의사결정이 요구되고 있다. 이에 본 연구는 기존 제품의 성능을 향상시키는 제품 개발 환경에서 신제품의 개발 및 판매기간 동안 이익을 극대화하기 위해 기업이 결정해야 하는 필수 요소인 신제품의 가격, 성능의 수준, 개발자원의 투입량 및 개발기간을 동시에 결정하는 통합적인 계량모델을 제시하였다. 모델에 대한 최적해는 Maple과 LINGO를 이용하여 산출하였고 파라미터 민감도 분석 결과를 통해 신제품 개발 상황에서 복합적이고 밀접하게 연관되어 있는 결정변수들에 대한 제품 개발 및 기술경영상에서 필요한 전략적 시사점을 제시하였다. Decision making for new product development (NPD) is essential for a firm to make profits through effective utilization of limited resources in a defined time horizon, thereby considerably affecting the firm's survival and growth in the competitive market. As the competition is more intensified with industry globalization, diversified customers’ needs and preferences, and decreasing product life cycle, an integrated decision making in NPD has become imperative. Therefore, this research investigates the situation where the current product's performance is improved incrementally and develops an integrated analytical model to simultaneously determine important factors in NPD, including the price of a new product, its level of performance, deployment of development resources, and development time in order to maximize profit during the development and sales period. Then we solve optimally the model which involves complex trade-offs among the decision variables, using Maple and LINGO. We perform sensitivity analyses to provide important managerial implications on NPD and management of technology, which can serve as a guideline for the decision making in practice.

공급업체 차별화 관리 전략의 효과성에 관한 실증 분석 방법론
송응석(Eungsok Song),김대수(DaeSoo Kim),박명섭(Myungsub Park) 한국구매조달학회 2015 한국구매조달학회지 Vol.14 No.1
공급업체의 차별화 관리는 기업의 경쟁력을 높이는데 중요한 사안이다. 그럼에도 불구하고 공급업체의 계층화 선정 기준과 공급업체 성과와의 관계 및 공급업체의 계층화를 통한 차별적 지원 전략과 공급업체 성과 향상과의 관계에 대한 연구는 매우 미흡한 실정이다. 따라서 본 연구는 선정 평가에 의한 공급업체 차별적 운영이 공급업체 성과에 어떠한 영향을 주는지를 실증적으로 고찰하였다. 이를 위해 세계적인 글로벌 제조기업인 X사의 443개의 실제 공급업체 관리 데이터를 이용하여 공급업체 차별화 관리 전략의 효과성에 대해 실층 분석을 하였다. 본 연구의 목적은 공급업체 계층화 관리에 대한 실증 분석을 통해 공급업체 선정 기준, 지원 전략 및 성과 간의 인과 관계를 규명하고 계층화된 공급업체 관계 관리에 대한 새로운 실무적 방법론과 시사점을 제시하는데 있다. Differentiated supplier management strategy is critical for enhancing firm competitiveness. Nonetheless, it is rare to find the studies of investigating the relationships between selection criteria for supplier segmentation and performance and between differentiated support strategy and performance improvement among segmented supplier groups. Therefore, this study intended to empirically explore the effect of supplier selection criteria on their performance and the effect of support strategy on performance improvement. To do so, we analyzed deeply the effectiveness of differentiated supplier management strategy by using 443 supplier data from a worldwide global manufacturing company X. The purpose of this study is to provide new practical methodology and insights in managing the segmented relationships among supplier selection criteria, support strategy and performance through an empirical study of segmented supplier management.

서비스 환경품질과 과정품질이 종업원만족과 고객만족에 미치는 영향에 관한 실증적 연구
임재풍(Jae-poung Lim),이윤숙(Younsuk Lee),박명섭(Myungsub Park),신호정(Hojung Shin) 한국경영과학회 2009 한국경영과학회지 Vol.34 No.4
In a service process, the customer typically experiences two types of interactions; one is interaction with the physical ambiance (servicescape) and the other is with employees who may be responsible for the service process quality. The literature in general supports that process quality is a critical determinant for overall service quality and customer satisfaction. In this paper, we primarily examine how the servicescape intervenes the association between process quality and employee/customer satisfaction. The proposed models are tested, using the data collected from the major golf courses in Korea. The results suggest that improving process quality and servicescape have a positive influence on employee/customer satisfaction directly and/or indirectly, but the effect of servicescape may be stronger in the case of golf course businesses. Servicescape also contributes to improving process quality by enhancing employee satisfaction. These results collectively indicate that management emphasis on improving service quality without renovating physical surroundings may results in unsatisfactory outcome.

Performance Advantage for Electric Vehicles under Competition
Dawoon Jung(정다운),Byung Cho Kim(김병조),Myungsub Park(박명섭) 한국경영학회 2018 經營學硏究 Vol.47 No.1
Although most electric vehicles (EVs) can cover the majority of daily driving needs, customers are anxious that they will run out of electricity on the road before arriving at the destination. Thus, the availability and accessibility of charging stations become critical for increasing sales in EV market. As well as charging convenience, customers are attracted by high-performance, meaning that all relevant features (acceleration, maximum speed, braking, riding comfort, durability, safety, charging time, etc.) need to be balanced. However, in many cases, achieving the optimal balance requires additional expense so that it may cause pressure on price despite its expected benefits. Thus, we investigate how the EV manufacturers can cope with the trade-off between lowering price and improving performance under competition. Then, we compare the equilibrium performance levels and prices of EVs when performance improvement costs of competing firms differ. We also examine the equilibrium decision from the social perspective and provide the implications of how the socially favorable decision is different from that for manufacturers.

Systemetic classification of a technology is critical to the development of technology strategy. This paper suggests a new technology classification scheme for computer and communication : a two-level scheme. Technology is first classified by its role and function in the upper level which forms a 2×2 matrix. The technology is then further classified into the lower level of 3 classes by associations among technology elements, Thus, a new classification scheme of 2×2×3 matrix is proposed for the computer and communication technology.

우리나라 정보통신산업의 기술수준 측정과 예측에 의한 기술개발전략의 수립 : Where we are now and How to go from here
황규승,박명섭,한재민,정종석 한국경영과학회 1993 經營 科學 Vol.10 No.1
This research analyzes the level of technological growth in Korean telecommunication industry and suggests a technology development strategy. Comparative analysis of technological growth with the advanced countries was performed based on a new technology classification scheme. Technology indices were calculated by applying Analytical Hierarchy Process(AHP). The result of the AHP was put into forecasting models to have a glimse of future growth pattern and to suggest a long-term development strategy for telecommunication technology.
