in electronic commerce markets, agents often should acquire multiple resources to fulfil a high-level task. in order to attain such resources they need to compete with each other. in multi-agent environments, in which competition is involved, negotiation would be an interaction between agents in order to reach an agreement on resource allocation and to be coordinated with each other. in recent ...

In this paper we propose a multi-objective mathematical model to aid the marketing team of a company in customer service marketing. Customer reflects to the services provided by a company, and the reflections affect the profit of the company. Thus, the services can be evaluated by the customers to imply the company's performances. First, the services are purified based on the opinions of th...

Cooperation and learning are two ways in which an agent can improve its performance. Cooperative Multiagent Learning is a framework to analyze the tradeoff between cooperation and learning in multiagent systems. We focus on multiagent systems where individual agents are capable of solving problems and learning using CBR (Case-based Reasoning). We present several collaboration strategies for age...

The importance of collaboration in the supply chain has led scholars to suggest diverse approaches for problems in the collaboration process. Questions still remain about which method is best when coordinating and sharing information in the presence of various supply and demand uncertainties. Hence, this paper aims to propose an integrated framework based on multi-agent collaboration and case-b...

This paper is to describe the PolyteCS simulation team. PolyteCS is the result of 15 months of research in RoboCup Simulation Research Lab. Our main goal in this project is to develop a multi-agent system based on fast and improved methods of learning and deciding in cooperative planning .We also introduce a new concept to make heterogeneous agents. To achieve this, PolyteCS uses case-based rea...

Chi-square tests are generally used for distinguishing purposes; however when they are combined to simultaneously test several independent variables, extra notation is required. In this study, the chi-square statistics in some previous works is revealed to be computed half of its real value. Therefore, the notion of Multi _ Chi-square tests is formulated to avoid possible future confusions. In ...

This paper describes how to utilise Case Based Reasoning for identifying and user situations assessment in a contextaware mobile system. The Case Based Reasoning mechanism attempts to identify what situation the user is in, and utilises a Multi Agent System, consisting of information suppliers, to provide the user with personalised and contextsensitive information.
