形式化

Forth, depending on a limited syntax language, a research on the method and process of the semi-formal specification of the top level function is developed. This top level specification paves the way for the system verification and the covert channel analysis.

对系统框架中的关键组件进行了伪码描述，并通过形式化的事务模型证明了事务系统对动态安全属性撤销的支持和良构事务构成的历史的可串行化的性质。

Keywords: Protocol performance testing, stochastic Petri nets, quality of service, tree and tabular combined notation.

分析了协议性能测试需要解决的主要问题，并以随机Petri网为形式化工具，描述了网络协议的服务质量。

Moreover, two classes CBIR system were discussed. Especially, the emphasis was put on the GIS supported CBIR and a set of such querying algebra operators was presented. The system frame and the general schema of CBIR based on image feature index were discussed as well.

并以GIS要素与遥感图像的空间关系为基础，着重分析了GIS支持的遥感图像基于内容查询系统的主要算子，对基于图像特征索引的内容查询，也作了一般形式化的讨论并给出了应用的系统框架。

After the formalization of the RMA problems, methods for normalizing the original stochastic decision matrix are proposed. For discrete RMA problems, the concepts of C-type solution and S-type solution are defined, and the inclusion relations between different sets of solution in the same type and between different sets of solution in different types are concluded. For continuous RMA problems, the decision analysis based on Dα-dominance relation is illustrated.

在对风险型多属性决策问题进行形式化描述之后，按照离散和连续两种情况，分别给出了风险型多属性决策属性数据的预处理方法；对离散风险型多属性决策问题，定义了C-类解和S-类解，并给出了各类解集之间的包含关系；对连续风险型多属性决策问题，给出了基于Dα优势关系的分析方法。
