摘要: 针对大型复杂项目的运行监控过程,提出一种基于分级模糊优选的进度计划调整模型。以两级模糊单元系统优选理论为基础描述计划调整的分级层次结构,通过指标特征值与混合相对优属度的计算,确定底层网络输入因素的相对优属度。运用语气算子结合决策序列排序,计算各单元输入系统的权重,获得计划调整的最优化方案。对某型汽车装配项目的网络计划进行仿真分析,验证了方法的有效性。

Abstract: Hierarchical fuzzy optimization is proposed on progress adjustment of hierarchical network plan. The theory of dual-pole fuzzy unit system optimization is utilized in establishing the hierarchical plan adjustment model. Based on the formula of relative membership degree to optimum for mixed indexes, indexes eigenvalue is used to confirm relative membership degree of input indexes. Fuzzy decision set of binary comparison and mood arithmetic operators are adopted to calculate weight of basic unit system. Simulation of the auto assembly project is analyzed, and result demonstrates the effectiveness of the model.

Key words: hierarchical network plan, plan adjustment, fuzzy optimization, project management
