最优过程

It mainly studies the choice of mode for competitive tender offer under different bidders' type.

首先，借鉴Perry，Wolfstetter和Zamir（2000）的有关理论，从基于两阶段密封价格投标的竞争性要约收购过程开始，讨论了其中的一些性质，结果表明，同质收购者前提下该过程不但能够获得和基于英式竞价的竞争性要约收购过程相同的期望收益，还能够克服后者存在的一些问题；随后，在异质收购者内生参与条件下就基于英式竞价和密封投标的竞争性要约收购过程进行了比较研究，得到了不同方式下收购结果的特征；最后，针对异质收购者不同知情程度的情况研究了竞争性要约收购方式的选择问题，借鉴Povel和Singh（2004）提出的机制，得到了具备"胡萝卜加大棒"性质的序贯出售过程是这种情况下控股股东的最优选择。

It provides a way to find optimal lower dimensional approximations of the given data, and It enormously reduce the storage of the data which is needed when the physical processes is recurred. The physical process can be described in series expansion function that only is related to the time and space. It is optimal approximation of the given data in a certain least squares optimal sense. The most obvious advantage of the method is that it reduces the computation cost and computation time markedly.

It's pointed out that soft sensor will play more important role in field bus network control system. According to this, a crude solution was addressed. At last, we point out that soft sensor technology must used to build an information warehouse for the whole enterprise, combined with data fusion, data warehouse, data rectification and other related technologies. The main contributions of this dissertation are as follows: The background, requirement, and application situation of soft sensors are expounded, the theories, methods and skills of soft sensing technology are analyzed, and the fruits and problems in current soft sensor technologies are summarized. Some new methods of soft sensor is proposed: A principal component analysis-based secondary variable selection method are proposed; A new conception which modeling data should have gross error detection is addressed, and then a cluster analysis-based modeling data gross error detection method is given.

本文的主要贡献有：对软测量技术根据实践的要求进行了一定的理论研究，针对具体问题提出了新的方法：讨论了辅助变量选择问题，研究了基于主元分析的辅助变量选择方法，该方法克服了传统方法只能利用数学模型产生的仿真数据进行最优辅助变量选择的缺点，可以根据历史数据进行辅助变量选择；提出了建模数据显著误差侦破的概念，指出传统的显著误差侦破研究的是已知过程数学模型的情况，而建模时数学模型是未知的，但是直接来自现场的数据并不能保证不含显著误差，并用基于聚类分析的方法解决了该问题，该方法利用聚类分析原理，直接面对过程数据，不需以过程模型为基础，在此基础上给出了软测量建模过程中样本数据的处理方法。
