Intrinsic Robustness Measurement for Multi-resources Constrained Project Schedules
, 2014 项目计划的内在稳健性的优劣决定了该项目计划能否成功实施。项目计划的内在稳健性度量指标是识别和制定稳健性项目计划的重要依据。基于16种优先规则制定项目计划和优化关键序列和资源链接,用33种度量指标测度项目计划内在稳健性并与j30,j60的网络计划算例的仿真结果进行对比。仿真结果表明,在j30,j60的每组480个算例中,内在稳健性度量指标RM5在均值和标准差方面都有最好的表现。Intrinsic robustness of a project schedule determines whether the
