A new approach for offer evaluation in multi-agent system negotiation based in evidential paraconsistent logic

This paper presents a Paraconsistent Approach based on a heuristic of multi-valued decrement list followed by formalization into Evidential Paraconsistent Logic to evaluate offers in a negotiation session. The mission of an organization stands for its goals and also leads corrections likely to occur in the posture adopted by the organization before the society. In order to fulfill the goals of the organization, this one needs to interact with other components of the society. Within an organization each individual responsible for the sale and purchase of either commodities or services detains knowledge concerning possible values of the criteria used to represent a determined commodity or service which may be either offered or accepted in a negotiation. So, an offer may be seen as an inconsistency caused by the previous individual knowledge of the negotiator and the incoming offer. When compared to the Utility Value Approach, the Paraconsistent one converges toward the negotiation ending with fewer interactions.

Avaliação de orientações geradas por sistema computacional a acompanhantes de pacientes pediátricos submetidos à quimioterapia

Objective To compare computer-generated guidelines with and without the use of a Clinical Decision Support System - Oncology Care and Healthcare for Chemotherapy Patients, for the caregivers of children undergoing chemotherapy. Methods This is a descriptive, evaluative, and quantitative study conducted at a paediatrics hospital in Curitiba, Paraná, Brazil, from December 2015 to January 2016. The sample consisted of 58 participants divided into two groups: Group 1, without the aid of software, and Group 2, with the aid of the software. The data were analysed using the Mann-Whitney U test. Results The guidelines revealed a statistical significance (p<0.05), with a prevalence of a higher concordance average in Group 2 in comparison with Group 1. Conclusion Computer-generated guidelines are a valuable qualitative support tool for nurses.

The use of paraconsistent logic in negotiation among artificial organizations

The mission of an organization stands for its goals and also leads corrections likely to occur in the posture adopted by the organization before the society. In order to fulfill the goals and achieved the mission of the organization, this one needs to interact with other components of the society. One kind of interaction which is very useful for organizations is the negotiation. To obtain a good result in a negotiation the responsible for the negotiation must use a good negotiation strategy; also he must know how to evaluate an offer according to the organization needings. The result of the offer evaluation will determine the actions that will be taken by the negotiator, either the offer will be accepted or a counter offer will be created. The use of paraconsistent logic provides a natural way, when compared to the utility value approach, to represent and evaluate the offer according to the organization knowledge. This paper presents a paraconsistent approach based on a heuristic of multi-valued decrement list followed by formalization into evidential paraconsistent logic to evaluate offers in a negotiation session.

A Paraconsistent Approach for offer evaluation in negotiations

The mission of an organization stands for its goals and also leads corrections likely to occur in the posture adopted by the organization before the society. In order to fulfill the goals of the organization, this one needs to interact with other components of the society. Within an organization each individual responsible for the sale and purchase of either commodities or services detains knowledge concerning possible values of the criteria used to represent a determined commodity or service which may be either offered or accepted in a negotiation. So, an offer may be seen as an inconsistency aroused between the previous knowledge owned by the negotiator and the offer. This article presents a Paraconsistent Approach based on a heuristic of multi-value decrement followed by formalization into Evidential Paraconsistent Logic to assess offers in a negotiation session. When compared to the Utility Value Approach, the paraconsistent one converges toward the negotiation ending with fewer interactions.
