设计模式及其在软件设计中的应用研究

总结了不同模式适用于不同应用的一般规律，分析了常用模式的内涵及侧重点，提出了设计模式应用于软件设计的策略，即抽象求解问题、划分问题类型、模式初选、模式匹配、根据问题进行模式变体、软件体系结构细化、设计优化、性能优化及设计质量度量．通过电力行业绘图平台的实际应用，给出了基于软件度量标准下的系统稳定性参数的计算方法．分析与实地测试表明，所提策略能够优化软件的设计及性能，为使用者提供了一种快速选取设计模式的途径．

Design Patterns and Their Applications to Software Design

The general laws of different design patterns adapting to various applications were reviewed and the intension of ordinary pattern and its focus were analyzed. The strategy applying the design pattern to software design, including problem-solving abstraction, problem type partition, initial pattern selection, pattern match, pattern variation according to the problem, software architecture refinement, design optimization, performance optimization and design quality measurement was provided. The calculation method of the system stability parameters based on the software measurement standards was given through the practical application of the plotting platform to the field of electrical industry. The practice and analysis show that the proposed strategy can optimize the software design and its performance, and provide users with a way to select design pattern.
