Automated Fuzzy Bidding Strategy for Continuous Double Auctions Using Trading Agent's Attitude and Market Competition

This paper designs a novel fuzzy competition and attitude based bidding strategy FCA-Bid for continuous double auction in which the best transaction price is calculated on account of the attitude of the agents and the competition for the goods in the market. The estimation of attitude is based on the bidding item's attribute assessment, which adapts the fuzzy sets technique to handle uncertainty of the bidding process. Additionally, it uses heuristic rules to determine the attitude of bidding agents. The bidding strategy also uses and determines competition in the market based on the two factors, number of the bidders participating and the total time elapsed for an auction using Mamdani's Direct Method. Then the range for the trading price will be determined based on the assessed attitude and the competition in the market using the fuzzy reasoning technique. The final transaction price is calculated after considering the conflicting attitudes of the seller and the bidder toward selecting the transaction price.
