The reference prices usually play a substantial role in customer purchase decisions. In this paper, aiming to the inventory systems about deteriorating products, a nonlinear programming model, combining the dynamic price with preservation technology investments, is built. One is used to determine the dynamic sales price, preserve technology investments and replenish strategy, for the maximize profits acquired by retailers. After that, some theoretical results are derived, and the existence of optimal solution is given. Finally, the model is effectively solved by a sequential approximate optimization algorithm by means of numerical tests.
