In this research, we developed a Multi-Agent based Negotiation Support System to be able to increase the competitive power of a company in dynamic environment and correspond to various orders of customers by diffusion of electronic commerce. The system uses the agent technology that is being embossed as new paradigm in dynamic environment and flexible system framework. The multi-agent technology is used to solve these problem through cooperation of agent. The system consists of six sub agents: mediator, manufacturability analysis agent, process planning agent, scheduling agent, selection agent, negotiation-strategy building agent. In this paper, the proposed Multi-Agent based Negotiation Support System takes aim at the automation of transaction process from ordering to manufacturing plan through the automation of negotiation that is the most important in order-taking transaction.

본 연구에서는 동적인 전자상거래 협상을 지원하기 위한 퍼지 AHP 기반의 협상지원 메커니즘 (Fuzzy AHP-based Negotiation support: FAHP-NEGO)을 제안한다. 협상은 단독으로 의사결정을 할 수 없는 둘 이상의 구성원간에 합의점을 도출하는 과정을 의미한다. 따라서, 여기에는 구성원 사이의 합의점을 도출하는 것이 매우 중요하다. 본 연구에서는, 이를 지원하기 위한 전자상거래 협상지원 메커니즘의 이론적인 배경으로서, 퍼지멤버십 함수와 AHP 기법을 사용하였다. 본 연구에서 제안한 협상지원 메커니즘은 정성적인 변수와 정량적인 변수를 모두 포함하고 있으며, 다중 협상과정을 통하여 전자상거래 협상을 지원한다. 건강보조식품 구매과정에 전사상거래 협상지원 메커니즘을 적용한 결과, 본 연구에서 제안한 전자상거래 협상지원 메커니즘이 정성적인 변수와 정량적인 변수를 반영한 전자상거래 협상을 지원할 수 있음을 보여주었다 본 연구의 후반부에는 향후 연구과제로서 전자상거래 협상지원 모형과 시스템 구축에 대해서 언급하였다.

As the advent of the Internet, B2B negotiation process on the Internet has been given attention from both researchers and practitioners. However, literature still shows that only structured conditions have been explicitly considered, despite the fact that unstructured conditions should be rendered as well. In this sense, this paper proposes a new negotiation support mechanism to incorporate causal relationships between structured and unstructured conditions in the process of B2B negotiation. Fuzzy cognitive map was used as a main source of causal knowledge as well causal inference engine. A prototype named CAKES-NEGO was developed to perform experiments with an illustrative example. Results revealed the robustness of our proposed negotiation support mechanism.

Information and Communication Technologies (ICT) changed our everyday business drastically. Business routines have been transformed to online activities. New theories and models were developed for the brand new online environment. For online negotiations, however, the research on new mechanisms is not enough, especially for bilateral distributive negotiations. A reserve price reporting mechanism (RPR) together with its extended version (ERPR) is proposed in this paper. The key improvement of reserve price reporting mechanisms is to let the negotiators report their reserve price to a third-party system before they actually start the negotiation. A prototype of this RPR system is developed and a lab experiment is conducted to test the performance of the two mechanisms compared with traditional direct bargaining (TDB) mechanism. The results of the experiment support that the reserve price report mechanisms proposed are more efficient than the traditional one in several dimensions including social welfare.

전자상거래의 확산에 따른 환경변화 속에서 다품종소량 생산하는 주문제조업체들이 다양한 고객들의 주문에 대응하고, 동적으로 변화하는 내 외적 기업환경 속에서 경쟁력을 제고시키기 위해 본 연구에서는 멀티에이전트 기반 협상지원시스템을 개발하였다. 이 시스템은 동적으로 변하는 환경과 고객들의 주문에 대응하고, 유연한 시스템구조를 이루는데 있어 새로운 패러다임으로 부각되고 있는 에이전트 기술을 사용하였다. 또한, 에이전트간의 협업을 통해 문제를 해결할 수 있는 멀티에이전트 기술을 사용하였다 본 연구에서 제시한 멀티에이전트 기반 협상지원시스템은 주문제조업체에서 가장 중요한 거래활동인 협상의 자동화를 통해 주문에서부터 생산에 이르는 일련의 모든 거래활동을 자동화하는 것을 목적으로 한다.

Internet-based distribution of digital contents provides great opportunities for producers, distributors and consumers, but it may seriously threaten users' privacy. The Digital Rights Management (DRM) systems which one of the major issues, concern the protection of the ownership/copyright of digital content. However, the most recent DRM systems do not support the protection of the user's personal information. This paper examines the lack of privacy in DRM systems. We describe a privacy policy and user's privacy preferences model that protect each user's personal information from privacy violation by DRM systems. We allow DRM privacy agent to automatically negotiate between the DRM system policy and user's privacy preferences to be disclosed on behalf of the user. We propose an effective negotiation algorithm for the DRM system. Privacy rules are created following the negotiation process to control access of the user's personal information in the DRM system. The proposed privacy negotiation algorithm can be adapted appropriately to the existing DRM systems to solve the privacy problem effectively.

Almost all result for group decision support systems (GDSS) have been obtained in a United States context, based on conventions and culture of American group processes. This paper reports on the construction and testing of a prototype GDSS to support international negotiation. The system was shown to work and to provide gains in both the quality of the interaction and the attitude toward the decision reached. Although the prototype system is narrow in scope, focusing on two specific cultures and a single scenario and uses simple and limited technology, the results obtained suggest that computer-based intercultural GDSS can help people in staving focused, in managing the added complexity of multinational negotiation, and in interacting effectively with one another.

The formation of a supply chain should be approached with distributive viewpoint considering the dynamic nature of ordering environments. The purpose of this paper is to design a semantic web to support agent negotiation forming supply chains. With the view of a supply chain as composed of competitive agents which represent each member of supply chains with a local goal, a supply chain is formed through negotiation of price, due date choosing partners to contract. In the development of a negotiation method, we employ ontology and rules which are the basic techniques of the semantic web for supporting automated negotiations. Especially, a framework for a negotiation process is suggested and domain, processes and rules ontology are designed interrelatedly. With this modeling, a possibility of the semantic web based agent negotiation is suggested.

인터넷 기반의 전자상거래에 참여하는 판매자와 구매자는 가격, 마진 등 다양한 거래조건들을 가지고 협상 (negotiation)을 진행하는 경우가 많다. 그러나, 기존연구에서는 대부분 가격과 거래량과 같은 두 개 미만의 정량적 (quantitative)인 거래조건을 중심으로 협상을 진행하는 방안을 중점적으로 다루었다. 그 결과, 단순한 실험적 문제에 대해서만 협상지원이 가능했고, 실세계의 전자상거래 협상과정에서 발생할 수 있는 다중 협상 요인들간의 동적인 변화를 고려하지 못했다는 지적을 피하기 어렵다. 본 연구에서는 이러한 점에 주목하여 전자상거래 판매자와 구매자가 웹 상에서 다차원적인 거래조건을 가지고 실시간으로 시뮬레이션을 하면서 보다 동적으로 협상을 수행할 수 있도록 퍼지 멤버심 함수와 AHP 추론기법을 이용한 전자상거래 협상지원 (Fuzzy AHP Negotiation support. FAHP-NEGO) 메커니즘을 제안하고자 한다. 실험결과, 협상에 필요한 정량적인 값과 판매자와 구매자의 주관적인 의사결정 행동양식이 반영된 보다 동적인 협상을 진행할 수 있었다. 따라서, 본 연구결과는 향후, 전자상거래 협상에 있어서 보다 현실적인 협상을 지원할 수 있을 것으로 기대한다.

With the proliferation of EC, many customers have been participating into online auction or group-buying market over searching internet shopping-malls to purchase goods. To support the customer's convenient transaction, lots of agent systems are developed to facilitate the customer's product brokering, merchant brokering, and negotiation of transaction. However, many of these systems have focused upon supporting transaction at only one type of marketplace. Since these marketplaces have different transaction settlement mechanism, it is necessary to develop the system that utilizes the customer's transaction including the selection of the type of marketplace to buy. Then we classify the kinds of B2C electronic marketplace according to the protocol by which the market operated. The structure of negotiation message is developed using XML schema and RDFS under the characteristics and message example of each marketplace in this research.
