Buyer Formation with Bundle of Items in E-Marketplaces by Genetic Algorithm

There exist several commercial websites selling similar goods. To date, however, most existing buyer coalition schemes over the Internet have no focused on forming a buyer coalition with bundles of items. This paper presents the approach to form buyer coalition with bundles of items by using the genetic algorithm (GA), called GAGroupBuyer scheme. Buyers post their orders with some reservation prices to any items in the package list. The GAGroupBuyer scheme finds best formation of sub groups (coalitions) which can give the best of group's utility. The simulation results are compared with the GroupBuyPackage scheme [8]. The results indicate that the algorithm can improve the total discount of any coalitions.
