简介：这篇文章在优秀通货膨胀的存在下面与消费者参考质量效果学习联合定价和动态产品质量投资的一个问题。最佳的控制模型被构造与一个有限优秀投资能力最大化全部的利润，在需求对历史的产品质量水平敏感的地方。为有限、无限的计划地平线的最佳的优秀投资策略被根据Pontryagins最大的原则解决这些最佳的控制模型分别地给，它随着时间的过去与引用质量效果使最佳的优秀投资的准确轨道能被描绘。另外，一个有效算法被设计为系统产生最佳的联合定价和动态优秀投资政策。有限计划地平线和无限的计划地平线的策略之间的主要差别是后者是一个常数。我们的学习显示公司在整个计划地平线一路上增加优秀投资从来不是最佳的。当考虑参考质量的影响时，优秀投资的水平更高。而且，数字例子被给说明理论结果的正当。另外，敏感分析被执行显示出系统参数怎么影响最佳的政策，并且一些经理的建议被介绍。
