Since the game theory provides a theoretical ground to distribute a shared resource between demanding users in a fair and efficient manner, it has been used for the bandwidth allocation problem in a network. However, the bandwidth allocation schemes with different game theory assign different amount of bandwidth in the same operational environments. However, only the mathematical framework is adopted when a bandwidth allocation scheme is devised without quantitatively comparing the results when they applied to the bandwidth allocation problem. Thus, in this paper, we compare the characteristics of the bandwidth allocation schemes using the bankrupt game theory and the bargaining game theory when they applied to the situation where nodes are competing for the bandwidth in a network. Based on the numerical results, we suggest the future research direction.

This study has tried to suggest a new model that can effectively redistribute the tickets in the online ticket resale market, while suggesting a new allocation mechanism based on an agent negotiation. To this end, this study has analyzed an auction in the online ticket resale market through Game theory. As a result of new agent mechanism, it has been proved that the price stability of ticket resale market leads to an increase. An agent negotiation helps to stabilize the ticket prices that are usually inclined to rise at auction, benefiting all the participants in the negotiations, consequently showing a Pareto solution. Especially, a framework for a negotiation process is suggested and domain and processes ontology are designed interrelatedly. With this modeling, a possibility of Ontology based agent negotiation is suggested.

This study is to conduct a stakeholder analysis using Project Stakeholder Management Model established by US Project Management Institute (or PMI) in order to identify current stakeholder related to Korea's trade policy and to establish the stakeholder management process for Korea's trade negotiation. Project Stakeholder Management Model includes four stages such as identifying, planning, managing, and controling stakeholder. The stakeholder management process for Korea's trade negotiation classifies domestic stakeholder into two category; internal stakeholder and external stakeholder. This research suggests that Korea should invite consumer groups, labor unions, and farmer's association into the official communication channel of trade authority while unifying the current stakeholder management divisions and relevant advisory committees within the trade ministry.

With changing software industry structure, the emerging concept called Software Ecosystems (SECO) has various challenges that software engineers have to overcome. In market-driven software product development, they should have the capability to offer high value products to their own business and their customers in order to being competitive. Each stakeholder's perspectives and interests should be reconciled in terms of requirements so that engineers can offer high value products through requirements selection. Existing works have just mentioned the need of requirements negotiation between stakeholders without proposing detailed guidelines or practice. In this work, a systematic Requirements Negotiation process is proposed to resolve conflicts of interests of stakeholders in SECO. The interests of stakeholders are analyzed based on goal-based requirements engineering. The rationale of requirements conflict is structured for management. A stepwise requirements negotiation process aims at resolving requirements conflict by applying game theory concepts based on self-interested behaviors of stakeholders.

Bandwidth is an extremely valuable and scarce resource in a wireless network. Therefore, efficient bandwidth management is necessary in order to provide high quality service to users with different requirements. In this paper, we propose a bandwidth reservation algorithm based on Nash Bargaining Solution. The proposed algorithm has low complexity and are quite flexible in the different situations of network. Simulation results indicate that the proposed scheme has excellent performance than other existing schemes.

This paper investigates the textile negotiations between Korea and the U.S. which Korea, as a weaker party in the bilateral trade negotiation, was recognized as making a good performance by Odell(1985). Using the documents of Korean governments at the time - Ministry of Foreign Affairs and the Ministry of Commerce and Industry - telegrams and reports from various sources the paper picks a leveling factor during the negotiations. In the paper, we used a dynamic concept of power for describing the negotiating power, and showed Korea succeeded in making the negotiation symmetric using the Special Cooperative Relationship(SCR) as one of the most conspicuous leveling factors during the textile negotiations with the U.S. The paper contributes to finding the factors that can be used in the negotiations with power asymmetry as a leveling factor for weaker country. Also, based on the findings from the paper, future negotiators can get insights on which factors be used, and how to use those factors for leveling the negotiations with a stronger counterpart.

협상은 상거래에 있어서 매우 중요한 요소 중 하나이다. 현재의 웹 기반 전자상거래 시스템은 이러한 중요한 협상 구조를 상거래에 잘 반영하지 못하는 문제점을 가지고 있다. 이러한 문제점중 기업과 소비자간의 미비한 협상 구조를 보안하기 위해 실세계 상거래에서 존재하는 점원을 전자상거래상의 가상점원으로 모델링하여 회사의 정책과 구매자의 특성을 반영하여 구매자와 전략적으로 자동 협상을 수행할 수 있는 에이전트의 구조를 설계하고 표현하고, 그 제안에 대한 평가 내용과 결정사항을 전달할 수 있는 언어적인 구조가 필요하며, 협상의 대상이 되는 사안들의 특성을 반영할 수 있는 표현 구조도 요구된다. 또한 이러한 협상에서 전략을 세우고 알맞은 제안을 제시하며 상대의 제안에 대하여 전략적으로 반응할 수 있는 의사결정 모델이 요구된다. 본 논문에서는 회사의 정책 모델과 구매자의 모델을 정의하고 이를 이용한 협상 모델을 설계 구현하였다. 협상 구조의 모델링을 위해 KQML(Knowledge Query Manipulation Language)을 기반으로 전자상거래 프로토콜로 설계하고, 논쟁 기반 협상 모델을 기초로 협상언어를 설계하였다. 또한 협상에서의 전략적인 의사결정을 위해 게임이론을 이용하고, 규칙 기반 시스템으로 이를 보충하였다. 마지막으로 가상점원 모델을 바탕으로 조립 컴퓨터 판매를 위한 가상점원으로 구현하였고, 이에 대한 실험을 통하여 가상점원의 유용성을 보였다.

Negotiation has been an important topic of M&A within entertainment industry. This research is aimed to investigate the process of M&A and related negotiation theories review and to analyze the Nexon sales failure case. M&A is a significant strategic decision-making made to ensure the sustainable competitiveness of Nexon. Nexon is generally more competitive action in negotiation context than rival game corporations. As a result, the negotiation about M&A is not completely succeeded. Nexon need to overcome the distributive strategy based on high anchoring (sales price). Also, Nexon need to be aware that negotiators who focus on the BATNA are more effective in claiming resources. Netmarble have low status and so is expected to be poor negotiation result. Because Nexon is perceived to be of higher status than Netmarble in an M&A process, Nexon is given the power to propose agreements. The practical and academic lessons of the present study are discussed.

Recently, many researchers have developed applications for automated contract and negotiation using agent technologies on electronic commerce. Especially, they have tried to study negotiation mechanism applying agent instead of buyers and sellers. Traditional researches, however, often had limitations. In the researches of automated negotiation, the agents had to negotiate with the other agents for a simple negotiation issue because the mechanisms were naive. In the researches of negotiation by user interaction, the agents did not have supported the procedures and methodologies for making the automated negotiation but only supported the users by providing communication environment during the negotiation process by users. In this paper, we propose efficient negotiation model using the modified negotiation model of the game theory. In the proposed model, the agents negotiate automatically with the partner agent and make good benefits by the strategic method during the negotiation process. Each agent makes negotiation issues with user's requirements and exchanges its suggestion alternatively in each step of the negotiation process. The agent evaluates degree of satisfaction for the opposite's suggestion and uses it in the next step of suggestion. To find out the negotiation strategies of opposite side, the agent uses teaming by weights of issues. As a result, the agent improves each own benefits for the contract and reduces the unbalance of its benefits through the proposed negotiation mechanism. We implement the negotiating agents according to the proposed mechanism and prove the efficiency of the proposed model by various experimentation.
