Under electronic commerce circumstance, it is very urgent for modern enterprise to solve the problem how to meet customer's individual demand. The availability of data on consumer profiles has opened new possibilities for companies to increase their revenue via data mining techniques. We study algorithms for the product-set pricing problem, where, given consumer preferences among products and the costs of production, the goal is to set prices of product-set, so as to maximize the overall revenue of the company. A price sequence matrix method is proposed to solve product-set pricing model, and an application to case study shows that the give method is effective.

We consider a class of models of consumer purchasing behavior, each of which relates observed data on a consumer's requirements and budget constraint to subsequent purchasing tendencies. The available data on consumer preferences together with sophisticated analytical tools enables companies' increases in profit through optimization of prices. We can study for the multi-product pricing problem based on this available data. Based on the description, three multi-product pricing modes include min-buying mode, max-buying mode, and mixed-buying mode, were presented. Proposed models were solved through genetic algorithms. Optimal solution of the given examples shows that this model is effective for enterprises.
