The main contributions are summarized as the following.Firstly, assuming demand is segmented by order lead time, a joint pricing and capacity allocation model is formulated considering scenario-based demand. Due to the stochastic discrete variable in the model, robust optimization is used to solve the model. Numerical examples prove our model and method reflect the stochastic characteristics of demand and provide more pratical pricing and capacity allocation policies than other methods of deterministic and stochastic expectation programming methods especially when the capacity is tight.

本文的创新之处概括为如下几个方面：首先，假设制造企业根据交货提前期对市场细分，建立了考虑需求情境的BTO模式下制造企业定价与能力分配的集成模型，利用稳健优化规划方法对此随机模型进行转化和求解，算例仿真表明随机优化规划方法较确定性规划和随机期望值规划方法更好地反映了随机离散需求的分布和波动特征，更加接近实际运作情况；产能越紧张，各类需求的价格差距越大，三种规划方法给出的最优策略差距越大。

The ratio of stock right calculated according to venture investment experiential principles is sound and easy to accept. It can give quantitative analysis support to the venture investment practice.(6)According to the theory of the real option, the author derived value formula of the real option fixed price and investment criterion. Based on above, the paper further research for optimal investment strategy of real option in monopolizing and competition under asymmetry information, and built the value model of real option for the investor and administrator by using the theory of the principle trust-agent Meanwhile, the solution of real option optimal investment and the shift value are derived applying the maximal principle .

针对高新技术企业发展的特点：研制周期长、投资费用高、每阶段风险水平特征差别大，运用实物期权理论与计算方法，通过研究建立嵌入期权现金流量图深入分析计算了企业发展中风险投资的最优策略、股权占有比例问题，对不确定性问题由于采用了有关实物期权计算公式，所以计算结果比基于传统的现金流量图的NPV方法更加客观、科学，同时按照风险投资经验法则计算出的股权占有比例合理易于接受，可为企业风险投资实践活动提供数量分析支持。
