The objective of this paper is to propose a Web-based Negotiation Support System(NSS) to facilitate conflict resolution between departments in a firm. As the management environment is recently becoming more complex and competitive, the need for harmonizing department functions in a firm is increasing much more than ever. In literature, most of conflict resolution approaches have been based on a sort of behavioral concepts including regular meeting or conference. However, as the department functions are wired through the Internet, a new approach to conflict resolution using the web-based technique is deemed necessary. For this purpose, we developed a Web NSS and illustrated a typical case in which conflicts between production and marketing functions are resolved using the Web NSS.

This Paper describes our experiences with the design and implementation of a networked multimedia information management system in an object-oriented framework for distributed multimedia applications, and an integrated QoS-resource negotiation protocol which has been applied to a video server in our networked multimedia infrastructure. The salient features of our framework to support efficient multimedia streaming are explained. Next the paper explores the challenges faced in integrating the proposed QoS negotiation policy into the framework.

As the size and complexity of network increase, Distributed Systems Management (DSM) will be significant issue within information network in order to increase the high reliability and to improve the flexibility of network management. The OSI management model has several problems. The key problems are that it does not fully address the problems of how to develop communication protocol in support of DSM, and how to classify the management connection criteria. In this paper, to solve first problem described above, this paper propose the connectionless CMIP(Common Management Information Protocol) to accomplish for effectively managing the distributed management system, and indicate its efficiency; this protocol is available to negotiate among the managing systems, handle the dynamic information. To work out second problem, we introduce the connection criteria in the hierarchy of management systems, and finally evaluate the efficiency of a suggested protocol during cooperative negotiation among the managing systems.

Today, there are several markets in cyber space where companies trade electronically due to the development of Information Technology. On the other hand, the most important thing in trades is negotiation. So, in order to support current business practices as well as new ones on the Internet, electronic commerce systems need an ability to negotiate. In this paper, proposed is a method by which a seller can be supported by an agent which plays a role in negotiation process among small and medium companies especially injection mold manufacturer. If the manufacturing capacity cannot afford to produce all orders, the manufacturer may want to extend due dates and the buyers may want to discount prices. The negotiation agent discussed in this paper cooperates with the schedule agent to get due-date information, and performs a role in one (seller)-to-many (buyer) negotiation processes.

본 연구에서는 부서간 갈등을 해결하기 위한 새로운 방법론으로서 웹 기반 협상지원시스템 (Web-based Negotiation Support System: Web NSS)을 제안한다. 기업의 경영활동에 있어서 각 부서간에는 여러 가지 이유로 인해 갈등이 존재한다. 대표적으로 생산부서와 마케팅 부서간에는 갈등이 항상 존재하기 마련이다. 예를 들어, 마케팅 부서에서는 수시로 변하는 고객들의 요구사항에 맞추기 위해서 제품라인을 확대하여 다양한 제품들을 생산하고, 그에 따른 높은 판매실적을 원한다. 그러나, 생산부서에서는 이와는 달리 적은 종류의 제품을 가능한한 한정적으로 생산하여 제품에 들어가는 원가를 절감하고 그에 따라서 생산실적을 높이려고 한다. 이 같은 유형의 부서간 갈등은 결과적으로 기업의 전체적인 성과를 저해시키는 요인으로 작용한다. 또한, 최근 대부분의 기업은 각각의 부서별 기능을 분산형태로 운영하고 있어서 관련부서가 지리적으로 멀리 떨어져 있게 되어 새로운 의사결정통합 지원시스템이 절실히 요구된다 본 연구에서는 이러한 상황에 적합한 새로운 유형의 갈등관리 메커니즘으로서 웹 기반 협상지원시스템을 제안한다. 본 시스템은 생산부서와 마케팅부서간의 갈등을 해결하고 이를 협상의 형태로 지원하기 위한 웹 기반 의사결정지원시스템이다. 본 연구에서는 실험과정을 통하여 제안하는 의사결정지원시스템의 성과를 증명하였다.

Since people have come to access more and more information about products with the proliferation of the Internet, more and more customer-to-customer e-marketplaces are being introduced with rapidly increasing transaction volumes. As the role of customer-to-customer electronic commerce has become increasingly regarded as vital to the economy, much research has delved into developing intelligent agent systems to efficiently support customer-to-customer electronic commerce. Most of this research, however, has focused only on supporting simple negotiation for the price of common goods along the time span. To expand the negotiation object to the differentiated goods, the customer must be allowed to negotiate over multi-at-tributes of the product besides the price, including the attributes related to the transaction activity itself, such as delivery time and payment method. To satisfy this requirement, we propose an agent marketplace for differentiated goods where the agent of a customer can negotiate not only the price but also the various attributes of the product and the transaction in order to achieve a better utility level for both buyer and seller. The formal protocol and the architecture issues to support the proposed e-marketplace and agents are also addressed.

This paper is aimed at proposing a new inference mechanism for B-to-B electronic commerce decision-makings, named IMITAO(Integer Matrix-driven Inference based on Transformed And-Or graph) which is based on integer matrix operation to speed up the inference. During the B-to-B electronic commerce, many kinds of negotiations are needed for mutually satisfactory decision-makings. During such negotiations, several factors including subjective and objective constraints should be considered so as to reach satisfactory decisions. In this respect, we suggest first a Transformed AND-OR Graph(TAOG) which each firm's conditions or judgement are incorporated into, and then we propose a high-speedy inference mechanism named IMITAO which basically depends on TAOG. Firms engaged in B-to-B negotiations on the Internet can get an appropriate decision support from using IMITAO for their negotiation simulations. The proposed IMITAO inference mechanism is characterized by its fast inference because its main inference procedures are based on integer matrix operation. A real-world example for B-to-B negotiations was used to prove the validity of our proposed TAOG and IMITAO approach. Experimental results showed that our approach was very useful in performing the B-to-B electronic commerce decision-makings considering a wide variety of either subjective or objective constraints.

The objective of this study is to investigate the effects of different meeting modes and task types on the outcomes of group decision making. The hypotheses postulate the potential effects of different meeting modes on appropriation process; different meeting modes on group outcomes; and the appropriation process on group outcomes. A laboratory experiment was conducted. A GSS was developed using Lotus Notes for this experiment. The results provide partial support for the hypotheses derived from the theoretical model. The interaction effects between meeting modes and tasks are not always observed in the analyses. However, groups using a face-to-face meeting mode in negotiation task reach significantly higher levels of perceived outcome quality, of satisfaction with the outcome, and of satisfaction with the process than groups using a dispersed-synchronous meeting mode. It suggests that a face-to-face meeting mode can enhance the effectiveness of groups working on a negotiation task such as stakeholder analysis. Furthermore, the manner in which groups appropriate the technology significantly influence the group performance. The results support the validity and usefulness of the IRT and the AST as a GSS research framework.
