The decision-making aspect of the negotiation process requires that participants collect and process information to determine alternatives, and to formulate offers and arguments. The communication aspect of negotiations involves exchange of offers, arguments and counterarguments. Collecting and processing new information involves learning, leading to modifications and adjustment of the decision...

Support for temporal text-containment queries is of interest in a number of contexts. In previous papers we have presented two approaches to temporal text-indexing, the V2X and ITTX indexes. In this paper, we first present improvements to the previous techniques. We then perform a study of the space usage of the indexing approaches based on both analytical models and results from indexing tempo...

Supplier selection is an important problem in supply chain management (SCM), and has attracted the attention of many researchers. Tremendous effort has been spent on the development of agent-based systems to automate supplier selection negotiation process in SCM applications. In this kind of multiagent system (MAS), software agents are established to represent various parties and functions invo...

Negotiation is a process by which a joint decision is made by two or more parties [1]. Typically one of the parties starts a negotiation by offering the most preferred solution from the individual area of interest. If an offer is not acceptable to the other parties they make counter-offers in order to move them closer to an agreement. Multi-issue negotiation (also called multi-attribute negotia...

The purpose of negotiation is to enable agents to coordinate their actions. Characterizing coordination in informationtheoretic terms leads us to consider negotiation in the context of other processes that can transfer information among agents, such as those mediated by the environment. We illustrate these concepts using the Minority Game, an abstract model of resource allocation that achieves ...

Negotiation occurs whenever people cannot achieve their own goals without the cooperation of others. Our review highlights recent empirical research that investigates this ubiquitous social activity. We selectively review descriptive research emerging from social psychology and organizational behavior. This research examines negotiation behavior and outcomes at five levels of analysis: intraper...

In this paper, a decision aid method for preoptimization is presented. The method is called “negotiation”, and it is based on the identification, formulation, modeling and use of indicators defined as “negotiation indicators”. These negotiation indicators are used to explore the solution space by means of a classbased approach. The classes are subdomains for the negotiation indicators domain. T...

Information about the opponent is essential to improve automated negotiation strategies for bilateral multi-issue negotiation. In this paper we propose a negotiation strategy that combines a Bayesian technique to learn the preferences of an opponent during bidding and a Tit-for-Tat-like strategy to avoid exploitation by the opponent. The learned opponent model is used to achieve two important g...

Following the emergence of the Internet, electronic negotiation has become an alternative to face-to-face negotiation. The current forms of negotiation support systems (NSS) used to support many electronic negotiations offer very little support for historical negotiation data. In order to address this issue, the idea of a collective memory support in negotiations has been proposed in recent yea...
