从决策支持系统需求分析的角度着手,将决策支持系统引入既有结构安全鉴定行业,首先对决策支持系统的应用做了简单介绍,结合影响既有结构安全性鉴定内容阐述决策支持系统的原理与功能设计,然后通过Microsoft Visual C++6.0下基于MFC的编程方式实现系统的人机交互部分,Microsoft Office Access 2003作为系统的数据库管理系统部分,应用Matlab对相应模型进行运算,共同实现传统的二库三角式决策支持系统。 Starting with the demand analysis of decision support system, the decision support system is introduced into the existing industry of structural safety appraisal. Firstly, the application of decision support system is briefly introduced. Combining with the principle of influencing the existing structural safety appraisal, Functional design, and then through the Microsoft Visual C + +6.0 MFC-based programming to achieve the system of human-computer interaction part of Microsoft Office Access 2003 as a part of the database management system, the application of Matlab to calculate the corresponding model to jointly achieve the traditional two Library triangular decision support system.
