基于可拓评价方法的工程项目方案选择

On scheme selection for engineering programs based on extension evaluation methods

基于可拓工程方法,构建了项目方案评价指标体系,利用定性等级和影响因子确定经典域和节域,计算关联函数及备选方案优劣等级,从而进行合理方案的选取。运用该法对工程实例分析证明,有效解决了方案的优化决策问题。

Based on extension engineering methods,the paper builds the evaluation indexes system of program schemes,adopts the qualitative level and impact factors to identify the classical fields and joint domain,the calculation correlation function and the superiority and inferiority of the alternative schemes,so as to have the reasonable selection for schemes,adopts the methods to have the analysis and evidence for engineering case,and solves the optimization decision-making issue effectively.
