A pri ing model is developed on the basis of an independent private evaluation model and some assumptions to maximize sellers profits, w ith a CPSO ( haos parti le sw arm optimization) solution given to it to seek optimal pri es. Simulation results revealed that the markdow n gradient in groupbuying a tivities may affe t the final gross sales, and the adjustment of markdow n gradient will improve the values of ustomers effe tiveness. More ustomers will therefore parti ipate in groupbuying a tivities to in rease sales so as to in rease the profit of ompanies.
