기업의 경쟁단위가 그 기업이 포함된 공급사슬로 확장되고 구매에 대한 전략적 측면이 강조되면서 구매자-공급자 기업간의 관계가 정예화된 장기적인 협력을 추구하는 경향으로 나타나고 있다. 따라서 구매자와 공급자간 협력의 요인과 행태에 대한 다각적인 분석과, 구매자와 공급자 양측의 관점을 포괄적으로 이해하는 것이 필요하다. 본 연구는 통신산업에서의 구매자와 공급자의 개별적인 측면에서 측정된 결과를 이용하여 구매자-공급자 비교연구를 실시하였다. 이를 통하여 구매자와 공급자가 가지고 있는 협력에 대한 인식과 행태의 차이를 발견할 수 있었다. 구매자 측면에서는 전환비용, 목적 호환성, 조직간의 신뢰가 중요한 협력의 설명 요소로 나타났으며, 공급자 측면에서는 기술적 예측불확실성, 목적 호환성, 공정성 인지가 중요한 협력의 설명 요소로 파악되었다.

This research is an application of game theory to developing the supplier selection and demand allocation mechanism, which are the essential and major research areas of supply chain planning and operation. In this research, the most popular and widely accepted mechanism, the progressive reverse auction is analyzed and compared with the other game theoretic approach, Kalai-Smorodinsky Bargaining Solution in the viewpoint of holistic efficiency of supply chain operation. To logically and exquisitely compare the efficiencies, a heuristic algorithm based on Genetic Algorithm is devised to find the other optimal demand allocation plan. A well known metric, profit-cost ratio, as well as profit functions for both suppliers and buyer has been designed for evaluating the overall profitability of supply chain. The experimental results with synthesis data and supply chain model which were made to mimic practical supply chain are illustrated and analyzed to show how the proposed approach can enhance the profitability of supply chain planning. Based on the result, it can be said that the proposed mechanism using bargainging solution mayguarantee the better profitability for the whole supply chin including both suppliers and buyer, even though quite small portion of buyer's profitability should be sacrified.

Given the recent trend in business markets to seek and conscientiously develop long-term relationships, it has become increasingly important to understand why such long-term relationships are developed and how they are maintained. Despite their obvious importance, the antecedent conditions and processes of long-term relationships between industrial buyers and suppliers have not been systematically studied. In this research, I report a study of the antecedents of industrial buyer-seller relationships and the relational performance. What kinds of factors contribute to the development of long-term relationships\ulcorner How do these factors influence the corporate performance in the business markets\ulcorner The primary motivation of this study was drawn from an interest in answering these research questions. Managerial implications of the study results are also discussed.

Brands are important in the consumer market. They are the interface between consumers and the company. And consumers may develop loyalty to brands. Also, the late development of industrial marketing explains the near absence of research on brand equity in business to business. With recent change, Industrial companies have shifted from a production focus to a customer focus. Industrial brand is fast developing. The basic purpose of this study is to investigate industrial brand trust and loyalty affecting the result of business relationship between industrial buyers and suppliers. Factors hypothesized to influence trust in a brand include a number of brand characteristics, company characteristics and consumer-brand characteristics. This research presented a comprehensive constructive model consisting of components of industrial brand trust and loyalty, and then propose the research model base on prior researches and studies about relationships among components of industrial brand loyalty Data were gathered from respondents who work in industrial buying center. For this study, Data were analyzed by AMOS 4.0. The results of this research analysis were as fallow. Industrial brand trust and loyalty were positively related with a number of industrial brand characteristics, supplier characteristics and buyer-brand characteristics, relationship commitment. This research newly proposed the concept of industrial brand trust and loyalty affecting the result of business relationship between industrial buyers and suppliers.

In the online shopping environment, consumers suffer from the process of selecting an optimal supplier. Although comparison shopping agent-based web sites and consumers' online community sites support the selection process, they have limitations when considering diverse and dynamic purchase conditions as a whole, which is the cause of additional consumer effort for optimal supplier selection. This study provides a decision support model with a sensitivity analysis for selecting an optimal supplier considering purchase conditions as a whole. It screens suppliers with filtering factors and provides optimal suppliers through a sensitivity analysis from a Quadratic Programming model. We implemented a prototype system and showed that it could be an effective decision support system for selecting the optimal supplier in the online shopping environment.

One of the most important issues of managing a supply chain is to determine the inventory level whenever shortage is permitted and vendor is responsible fur management of the both buyer and supplier's inventory. We present two vendor managed inventory models in the form of two-echelon supply chain models for: 1) one buyer-one supplier problem, and 2) two buyers- one supplier problem. We assume that shortage is permitted. The proposed methods of this paper provides a simple condition, which makes it easy to decide when and how vendor managed inventory model costs less than traditional one. The paper is supported with some numerical examples to show the implementation of the proposed methods.

The advent of the Internet and development of information technologies have changed the environment of doing business. Accordingly, they expect that the relative importance of electronic commerce in the business becomes growing more and more. Among the areas of electronic commerce, B2B marketplaces that play the roles of linking buyers and suppliers take the important place. This study examines requirements for activating domestic B2B marketplaces by analyzing the literature and the status of the marketplaces. For the analysis, evaluation factors that belong to one of the four categories (i.e., Information step, Agreement step, Settlement step, and the rest) are selected. Results of the study suggest the following activation requirements for domestic B2B marketplaces : 1. Enforcement of services for the Agreement and Settlement steps. 2. Supporting multinational languages. 3. Diversification of income sources. 4. Standardization. 5. Integrating main systems. 6. Satisfying the necessities of buyers and suppliers.

기존의 전력산업은 전력에너지 단일 품목에 의한 공급자 중심의 서비스체제를 유지해왔으나, 전력산업의 환경변화에 따라 소비자의 역할과 요구가 증대되고 있다. 또한 인터넷에 기반한 정보기술의 발전은 서비스 수용자로서의 전력소비자의 역할을 가격 결정권과 서비스 공급자 선택권을 갖는 시장 참여자로서의 역할로 변모시키고 있을 뿐 아니라 전력서비스 이외의 다양한 부가서비스의 제공을 요구하는 멀티서비스 구매자로까지 확대시키고 있다. 하지만 이러한 소비자의 역할이 현실화되기 위해서는 전력시스템과 소비자 전력기기간 양방향 통신을 기반으로한 멀티서비스 플랫폼의 구현이 필수적이다. 본 논문은 전력소비자의 멀티서비스를 위한 두 가지 모델을 제시하고 비교 분석하였다.
