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。

According to the echocardiography,enlarged internal diameter of left ventricle was found in 8 patients and short-axis fractional shortening of left ventricle 5% in 3 patients.Six out of the above 8 patients presented with shortening of accerlerating time,decreasing of accerlerating time/right ventricular ejective time value and moving forward of spectral peak in different degrees.All patients were given antianginal drugs such as β-recepter blockers,nitrate preparations and part by angiotensin converting enzyme inhibitor,diuretics and digoxin,The illncss of 29 patients were gradually controlled within one week.Three patients with AD were complicated by acute left heart failure.No obvious changes in FS of left ventricle were found on echocardiography by bed.

测量肺动脉瓣口血流频谱，左心室内径增大的8例中有6例出现不同程度的血流加速时间缩短，血流加速时间/右心室射血时间比值减小，频谱峰值前移。31例均给予β受体阻滞剂、硝酸酯类等抗心绞痛治疗，部分给予血管紧张素转换酶抑制剂、利尿剂和地高辛，其中29例在1周内卧位型心绞痛逐步得到控制。3例卧位型心绞痛发作时合并急性左心衰竭者，在床旁观察超声心动图，发现左心室短轴缩短率无显著变化，给予利尿剂、减轻前后负荷等治疗，急性左心衰竭得以纠正。
