A Formal Basis for Negotiation Support System Research

A high-level theoretical model of negotiation activity is introduced as a foundation for guiding future research and development in the area of negotiation support literature. A formal model at this level is presently absent from the negotiation support systems. The model is formally expressed in terms of definitions and postulates that describe eight important negotiation parameters. Relationships between the model and research in game theory, social behavior science, and decision support systems fields are examined.     

Modeling e-Negotiation Processes for a Service Oriented Architecture

Most of today's e-marketplaces support a single negotiation protocol. The protocol is usually built into the e-marketplace infrastructure, therefore if a new one is introduced then a time consuming and complex process of implementing it takes place. Moreover, participants in the e-marketplace need to adapt their interfaces to the new protocol, especially if they use automated tools to interact with the e-marketplace. This paper reports on a model-driven approach and a framework for rapid and user-friendly development of configurable service oriented e-negotiation systems. We believe that a formal specification of negotiation protocols and their separation from the market infrastructure that implements them is a step towards configurable e-negotiation systems. The protocols are graphically designed for the e-marketplace then mapped into web service orchestrations. Participants use automated negotiation systems to interact with the e-marketplace. These systems are generated based on the negotiation protocol implemented on the e-marketplace. A declarative language is used to specify negotiation strategies and tactics. We propose an algorithm to map Statechart models of negotiation protocols into web service orchestrations and we report on the current implementation of our framework.     

B2B Negotiation Support: The Need for a Communication Perspective

Negotiation support is an important challenge for business-to-business e-commerce that is still poorly supported in current information systems. One reason is that negotiation processes are much harder to formalize than the business processes in the fulfilment phase. The goal of this paper is to provide the basis for a formal analysis of different types of electronic negotiations which can help developers of future negotiation support systems. The analysis is performed from a communication perspective, in particular, Habermas' theory of communicative action. Using this perspective, a distinction can be made between norm-oriented, goal-oriented and document-based negotiation. Whereas traditional modeling methods take a data-oriented view, the theory of communicative action supports a communication-oriented view that provides more insight in the logic of negotiation processes. The analysis forms the basis for the negotiation support prototype implemented within the ESPRIT project MeMo (Mediating and Monitoring Electronic Commerce) which was aimed at B2B e-commerce for SMEs in Europe.     

ESD: A Formal Consciousness Model for International Negotiation

We develop the Evolutionary Systems Design (ESD) formal consciousness model for international negotiation extending the usual cognitive rationality of formal models to right rationality validated subjectively by cognition, affection, conation, holistically, and spiritually. Two subjective validation tests for right rationality are described. The purpose is to attain right negotiation agreements in international negotiation. Practice and computer implementation are discussed and applications presented. Though the ESD general formal mathematical model is an evolving difference game, in applying it to specific problems mathematical symbols are not normally used, relations between generally familiar sets of elements being expressed by tables (matrices). We believe that ESD can help close the gap between formal modeling and practice of international negotiation.     

Towards a Structured Design of Electronic Negotiations

Global communication networks and advances in information technology enable the design of information systems facilitating effective formulation and efficient resolution of negotiation problems. Increasingly, these systems guide negotiators in clarifying the relevant issues, provide media for offer formulation and exchange, and help in achieving an agreement. In practice, the task of analysing, modelling, designing and implementing electronic negotiation media demands a systematic, traceable and reproducible approach. An engineering approach to media specification and construction has these characteristics. In this paper, we provide a rationale for the engineering approach that allows pragmatic adoption of economic and social sciences perspectives on negotiated decisions for the purpose of supporting and undertaking electronic negotiations. Similarities and differences of different theories that underlie on-going studies of electronic negotiations are identified. This provides a basis for integration of different theories and approaches for the specific purpose of the design of effective electronic negotiations. Drawing on diverse streams of literature in different fields such as economics, management, computer, and behavioural sciences, we present an example of an integration of three significant streams of theoretical and applied research involving negotiations, traditional auctions and on-line auctions.     

Negotiators' Communication, Perception of Their Counterparts, and Performance in Dyadic E-negotiations

The aim of this study was to improve our understanding of negotiation strategies, behaviors, and outcomes, and the relationships between these factors based on data collected from questionnaires, actual behavior during the negotiation process implemented using e-negotiation system, and the negotiation outcomes. This study clustered the negotiators based on either the negotiators' own strategies or their thoughts about those of their partners. This resulted in a division into cooperative and noncooperative clusters. We found that the negotiators whose own strategies are less cooperative tend to submit more offers but fewer messages. However, these people consIDer that they have less control over the negotiation process compared with those who adopt a more cooperative strategy, who make fewer offers but send more messages. Those in the cooperative cluster consistently feel friendlier about the negotiation and more satisfied with the outcome and their performance. Further, there is a correlation not only between self-strategies and the thoughts about partners' strategies, but also between strategies and final agreements. Finally, the proportion of negotiations reaching agreement is larger for the cooperative cluster than for the noncooperative cluster.     

On automated e‐business negotiations: Goal,policy, strategy,and plans of decision and action

In recent years, there has been increasing interest in automated e‐business negotiations. The automation of negotiation requires a decision model to capture the negotiation knowledge of policymakers and negotiation experts so that the decision‐making process can be carried out automatically. Current research on automated e‐business negotiations has focused on defining low‐level tactics (or negotiation rules) so that automated negotiation systems can carry out automated negotiation processes. These low‐level tactics are usually defined from a technical perspective, not from a business perspective. There is a gap between high‐level business negotiation goals and low‐level tactics. In this article, we distinguish the concepts of negotiation context, negotiation goals, negotiation strategy, and negotiation tactics and introduce a formal decision model to show the relations among these concepts. We show how high‐level negotiation goals can be formally mapped to low‐level tactics that can be used to affect the behavior of a negotiation system during the negotiation process. In business, a business organization faces different negotiation situations (or contexts) and determines different sets of goals for different negotiation contexts. In our decision model, a business policymaker sets negotiation goals from different perspectives, which are called goal dimensions. A negotiation policy is a functional mapping from a negotiation context to some quantitative measures (or goal values) for the goal dimensions to express how competitive the policymaker wants to reach that set of goals. A negotiation expert who has the experience and expertise to conduct negotiations would define the negotiation strategies needed for reaching the negotiation goals. Formally, a negotiation strategy is a functional mapping from a set of goal values to a set of decision‐action rules that implement negotiation tactics. The selected decision‐action rules can then be used to control the execution of an automated negotiation system, which conducts a negotiation on behalf of a business organization.     

Implications of Negotiation Theory for Research and Development of Negotiation Support Systems

This paper summarizes a parametric theory of negotiation as a basis forshedding light on negotiation support system possibilities. Previously, thetheory has been used to analyze prior research accomplishments in the area ofnegotiation support systems. Here, we discuss implications of the theory thatare relevant for future research and development of negotiation supportsystems. The implications are concerned with three topics: a high-levelgeneric characterization of these systems, an identification of theirpossible support functions, and a taxonomy for classifying suchsystems.     

Design and Implementation of Business Objects for Automated Business Negotiations

In recent years, there has been increasing interest in the specification, generation and exchange of business objects in the context of electronic commerce. Common business objects have been defined for product catalogs, purchase orders and other business entities. However, no business objects have been defined and implemented for supporting automated business negotiations even though business negotiation is very much an integral part of business activities. In this work, we have designed and implemented a set of business negotiation objects for supporting the bargaining type of business negotiations. These objects define the operations and information contents needed for negotiation parties to express their requirements and constraints during a bargaining process. They correspond to a set of negotiation primitives, which is a superset of the negotiation-related primitives defined in two popular languages: ACL and COOL. The implementation of these objects is patterned after the business object documents in the XML format proposed by the Open Applications Group, thus conforming to the established standard. The incorporation of several types of constraint specifications in these business negotiation objects provides the negotiation parties and the negotiation servers that represent them much expressive power in specifying callforproposals and proposals. Two synchronization problems and their solutions associated with the withdrawal and modification of negotiation proposals are addressed and presented in this paper. The use of these business negotiation objects in a bilateral bargaining protocol is also presented. We have validated the utility of these objects in an integrated network environment, which consists of two replicated negotiation servers, two commercial products, and some other university research systems that form a supply chain.     

E-Alliance: A Negotiation Infrastructure for Virtual Alliances

In this paper we provide an overview of E-Alliance, a software infrastructure we are developing to support negotiation activities in concurrent inter-organisational alliances. Our baseline is to offer a collaboration framework which fully preserves the autonomy of organisations grouped in an alliance, while enabling concurrency of their activities, flexibility of their negotiations and dynamic evolution of their environment. We propose to support negotiation between the partners within such alliances by combining different technologies, such as software engineering techniques, middleware-level coordination facilities and multiagent systems support. We present our approach in the context of a sample scenario of an alliance where partners are printshops capable of (out/in) sourcing print jobs among them to better accomplish their customers' requests.     

An empirical study of an interactive,session-oriented computerized Negotiation Support System (NSS)

Negotiating is one of the four major decisional roles played by managers. In fact, resolving conflict is said to occupy 20% of a manager's working hours. This growing frequency of negotiation scenarios coupled with the increasing complexity of the issues which need to be resolved in a negotiation make the possibility of computer enhancement for negotiation very appealing. Implementations of computerized Negotiation Support Systems (NSS) in the business world, international affairs, labor law, and environmental and safety disputes have demonstrated their potential for making negotiation problems more manageable and comprehensible for negotiators. Still, pioneers in NSS research have expressed their dismay at the lack of rigorous empirical research and evaluation of NSS. In particular, research is needed which will determine how and under what circumstances negotiation processes can be enhanced by NSS support.This article describes empirical research on the effects of a highly structured, interactive NSS on the outcome of face-to-face issues resolution and the attitudes of negotiators in both low- and high-conflict situations. In a laboratory experiment, bargaining dyads played the roles of manufacturers negotiating a four-issue, three-year purchase agreement for an engine subcomponent in conditions of high and low conflict of interest. The results of the study showed that NSS support did help bargainers achieve higher joint outcomes and more balanced contracts, but that the NSS support increased negotiation time. Satisfaction was greater for NSS dyads in both conflict levels, and perceived negative climate was reduced in low conflict.One primary implication of the results of this study is that NSS developers should keep in mind the importance of providing users with a system with interactive qualities which not only enhance the decision-making process but also provide them with a sense of participation in reaching the solution, as was done in this study.     

A Multi-Attribute Negotiation Support System with Market Signaling for Electronic Markets

Despite the rapid growth of technology and Internet-based markets, many of the current systems limit themselves to price as the single dimension variable and offer, if at all, only minimal negotiation support to the consumer. In the real world, commercial transactions take into account many other parameters both quantitative and qualitative such as product quality, speed, reputation, after sales service, etc. This paper discusses how these multiple attributes can be captured to augment standard negotiation processes in order to support electronic market transactions. Using a combination of utility theory and multicriteria decision-making, we propose heuristic algorithms to discover potential trades. In addition, the approach is included within a larger framework that incorporates market-signaling mechanisms. This not only allows for the systematic evolution of negotiation positions among buyers and sellers but can ultimately lead towards improving both market transparency and efficiency. To illustrate the multiple criteria model coupled with the dynamic market signaling framework, we report in this paper the implementation of a Web-based clearinghouse that serves the real estate market.     

Connectedness Problem Solving and Negotiation

Difficult polarizing problems/conflicts are pervasive in the United States and the world. Welcome to spiritual rationality/connectedness problem solving and negotiation involving spirituality and rationality, and emphasizing connectedness in problem solving. In particular, we develop CPSN-ESD—Connectedness Problem Solving and Negotiation (CPSN) through Evolutionary Systems Design (ESD)—discussing spiritual rationality/connectedness and highlighting connectedness with One and with each other as values, among others, in problem solving. In CPSN-ESD, CPSN is effected through ESD, a game-theory based, general formal systems- spirituality modeling/design framework for individual and multiagent (group) problem solving and negotiation implemented by computer technology. Problem solving is represented by an evolving problem system of purposes and their relations from the lowest-level action to the highest purpose, ultimate common ground—spirituality, connectedness with One (or a surrogate, as discussed). For an agent, an evolved problem system satisfying spiritual rationality identifies right action (a solution) producing spirituality, connectedness with One (or a surrogate). A negotiation agreement requires multiagent agreement on the action to be taken. Agents may be natural or artificial. The paper focuses mostly on human agents with ideas being applicable to other natural and artificial (computer) agents with lesser (or greater) capabilities than humans according to their built-in capabilities. Present-to-future CSPN-ESD work includes furthering support of human agents; designing spiritual agents; designing multiagent systems for connectedness capitalism; developing connectedness democracy; further research and applications on intercultural and international negotiation; work on the world connected.     

Consciousness, Spirituality and Right Decision/Negotiation in Purposeful Complex Adaptive Systems

Both cybernetic and self-organizing, purposeful complex adaptive systems (PCAS) express purpose by solving problems defined by choosing and delivering values to participants as operational goals through decision making. Individuals, groups, organizations, and economies are PCAS. Here we focus on indviduals and groups. Evolutionary Systems Design (ESD) is a universal (culture independent) general problem solving, formal modeling/design framework for PCAS that can be computer implemented in same time/same place or telework modes. Formally, in ESD sets of elements and their relations modeling a PCAS evolve through cybernetics/self organization. Spirituality and the concept of right decision/negotiation in PCAS are discussed in relation to consciousness. Rightness comes from spirituality, i.e., consciousness experiencing oneness. Oneness is integrally bound with love; hence the term oneness/love. Through right decision/negotiation PCAS try to realize their ultimate purpose to live Two (the relative, the process of all there is) as One (the absolute, all there is). Oneness/love, connectedness to One, promotes problem solving and negotiation - expressed formally in the ESD problem representation - that is at the same time right. Simply put, right problem solving requires oneness/love and delivers oneness/love. Computer and receiver modes of consciousness are discussed in relation to oneness/love and its absence experienced as separateness/fear. Ways to transit from the latter to the former are considered. P.L. Yu's Habitual Domain (HD) framework is introduced and discussed in relation to ESD. Evolutionary heuristics for evolution of an ESD right problem representation through cybernetics/self-organization are presented based on combined HD and ESD concepts. Then operational procedures for defining and validating a right problem for an individual or group and associated right decision/negotiation outcome are considered. Thus, the work contributes to procedural rationality - how decisions should be or are made - in purposeful complex adaptive systems. The paper suggests that for humans to live fully (awake) is to live in our love-based spirituality, in the moment, consciousness experiencing oneness/love at the edge of chaos, challenged in our purpose to live Two as One by spiritual or right decision/negotiation through cybernetics/self-organization, i.e., problem solving under oneness. Artificial agents in PCAS may participate in right decision/negotiation. They may in principle have consciousness but the nature of the subjective experience is unclear.     

模拟谈判法在国际商务谈判教学中的应用研究

模拟谈判法是在国际商务谈判实践教学中行之有效的教学方法之一。模拟谈判法的实施过程包括选择模拟谈判案例、合理分组、模拟谈判前的准备工作、实施模拟谈判、教师点评与总结、谈判报告的完善与提交六大步骤。目前的模拟谈判教学实践在课程设置、教学条件、学生掌握程度和运用能力等方面仍存在问题,应从建立专门的谈判室、提高教师的综合水平、加强英语在模拟谈判中的使用、提高实训考核所占比例等方面加以改善。     

An ESD Computer Culture for Intercultural Problem Solving and Negotiation

Intercultural problem solving and negotiation involves interaction of two or more cultures. These processes may be formally modeled using the Evolutionary Systems Design (ESD) framework implemented by appropriate computer group support systems (GSS). The ESD/GSS combination provides an ESD computer culture for intercultural problem solving and negotiation in a same place/same time or telework mode. With this, players in a multicultural group can be computer supported in generating and formally representing an evolving common culture (a situational culture) with regard to the specific problem at hand - an intercultural evolving group problem representation and solution. At the same time, the ESD computer culture provides an operational cybernetic/self-organization framework for the empirical study of cultural emergence in a multicultural group. This paper uses and develops work by Shakun (1996b).     

How to Attain Desired Outcomes Through Channel Conflict Negotiation

Channel relationships are dynamic and complex. Though much of channel literature has dealt with power, dependency, and conflict resolution, relatively little research focuses on how channel members apply different modes of negotiation to resolve channel conflicts and, most important, how they finagle their ways through different stages of negotiation to obtain desirable outcomes. This article suggests that in deciding which strategy to adopt to effectively negotiate with others, channel members should take into account two vital outcomes during the negotiation process: substantive gain and relationship outcome. Integrating high versus low levels for each of these two types of outcomes, this study develops a framework for channel conflict negotiation in an international setting and recommends appropriate negotiation strategies for various scenarios and phases of negotiation.
