中文摘要：

在BOSC环境下，考虑回收策略及模块化影响的利润模型基础上，进一步研究了价格折扣因素对于该利润模型的影响，使得模型更能体现接单式生产的特点。通过对改善后的模型的研究发现，采用价格折扣不一定是每一个生产商首选的促销手段，价格折扣选择不当会直接影响生产商的利润，并且在此模型中能够确定最大利润条件下的模块化程序和回收价格。

英文摘要：

The profit model on the condition of considering return policy and modular design under the BOSC environment was improved by considering the price discount, in which the character of BTO （build -to-order） can be expressed sufficiently. Results show that price discount strategy as a kind of sales promotion skills is not the first choice for every producer. Maybe it is harmful to the producers if they can not choose a suitable price discount strategy. And the producers can deal with the size of price discount and find that the optimal return policy and modular design depend on this new model to get the maximum profit.
