According to the O2O orders demand situation that manufacturers accept at present, the commodity demand influence factors and demand interaction analysis, we researched different types of commodities by the superposition of O2O demand requirements model and found that with the deepening of the double channel, less cyclical factors will affect demand. Finally, in combination with block change model to optimize the double channel interaction model on the basis of demand, combined with the characteristics of several commodities are simulated respectively, we could get demand coupling optimization model.
