摘　　要：从不确定性的角度考虑计划网络的关键路问题,对于网络活动时间为区间灰数的情形,根据灰色系统理论和区间灰数计划网络的特点,给出了多目标关键路的概念和确定关键路的方法.实例分析表明该方法把主客观因素结合,更具合理性.We make a discussion on critical path problem of the uncertain plan network in which activity times are presented as interval numbers.According to grey systems theory and the characteristics of interval plan network,the concept and the method of the multiobjective critical path are introduced.Examples are provided at the end to verify the feasibility of this method which combines subjective factors with objective one.
