E-procurement transactions in Business to Business (B2B) environment showed a constant and positive trend in the last years. The most popular methodologies to support these tools are all related to dedicated protocols able to facilitate the agreements among customers and suppliers. This chapter proposes a Multi Agent Architecture integrated with several multi-attribute auction mechanisms specif...

Auctions and negotiations are mechanisms used in market exchanges. Behavioral economics experiments focused on the mechanism efficiency which required highly simplified problems and contexts. This paper discusses an on-going project involving an experimental comparison of auction and negotiation mechanisms embedded in software which we have developed. The experiments are situated in an e-busine...

Comparative studies of auction and negotiation exchange mechanisms are inconclusive. These studies have typically compared outcomes obtained from the two mechanisms. The question which this paper aims to address is the viability of outcome-based comparisons. Such comparisons assume that both mechanisms produce the same types of outcomes but their values differ. An argument can be made that this...

Abstract The incentive mechanism of federated learning has been a hot topic, but little research done on the compensation privacy loss. To this end, study uses Local SGD federal framework and gives theoretical analysis under use differential protection. Based analysis, multi‐attribute reverse auction model is proposed to be used for user selection as well payment calculation participation in le...

the sensitivity analysis for multi-attribute decision making (madm) problems is important for two reasons: first, the decision matrix as the source of the results of a decision problem is inaccurate because it sorts the alternatives in each criterion inaccurately. second, the decision maker may change his opinions in a time period because of changes in the importance of the criteria and in the ...

To be successful in multi-attribute auction, agents must be capable of adapting to continuous changing bidding price. This paper presents a novel fuzzy attitude based bidding strategy (FA-Bid), which employs dual assessment technique i.e. assessment of multiple attributes of the goods as well as assessment of agents attitude (eagerness) to procure an item in automated auction. The assessment of...

Auctions have been getting increasing attention in computer science and economics, as they provide an efficient solution to resource allocation problems with self-interested agents. E-Commerce and finance have emerged as some of their largest application fields. The need for new auction mechanisms that allow complex bids such as bundle or multi-attribute bids has been raised in many situations....

Auction-based models and protocols introduce money and pricing as the technique for coordination between users and producers of resources in grids. In this paper, we propose a multi-attribute reverse auction protocol to allocate grid resource. In order to enhance the information efficiency we develop a novel interactive approach supporting both user agents and producer agents. In this approach,...

We consider a multi-attribute outsourcing economy where both price and delivery date are relevant decision factors. In the economy, there is an Original Equipment Manufacturer (OEM) who needs multiple items to be delivered on the predetermined delivery dates and suppliers who are capable of delivering some or all of the items. We first show that there exists a competitive equilibrium in this ec...
