A d namic pricing model is thus developed to minimize the loss of profit on a restricted condition that the volume of goods is needed to sell off. B the genetic algorithm and particle swarm, a pricing is given with optimal cost. The effect of pricing on loss of profit is anal zed through a simulation so as to provide an important reference for promotional decision-making in large/ middle-scale companies. Key words: seasonal commodities; promotion; discount rate; d namic pricing; model; algorithm [ 5] [ 6] , , ,
