Abstract
With the development of the Internet and technology, the traditional market has become an electronic market, and the value of trading has become more than a traditional market. The Small and Medium Enterprises (SMEs) e-commerce has been growing rapidly and more businesses have used the e-commerce for selling and buying goods or services. Consequently, most of the plastic e-marketplaces only allow the large companies to search the product and then contact the other large companies by email or phone. The e-marketplace needs automated or intelligent agents; 1) in order to automated purchasing consortium among the SMEs, 2) in order to conduct automated negotiations between the buyers and the seller. However, this paper implements an automated consortium agent among buyers to build a consortium for SMEs and automated negotiation agent allows SMEs and/or large Enterprises (LEs) to negotiate with the seller. Also, the efficiency of the simulated system in the plastic market is demonstrated by a series of simulations in which the result is negotiation between SMEs with the seller and LE with the seller.
