摘要
挣值法作为项目管理中一种集成控制的重要工具,可将成本进度联合监控,从而达到有效控制的目的。但是在挣值法应用中发现,传统挣值法存在未区分关键路径、难以给出项目内部具体执行计划等问题。针对传统挣值法存在的问题,结合PERT技术提出二级挣值法,对关键路径和非关键路径的活动区别对待;结合PDCA循环,定时检查计划成本进度目标与实际目标相比较,检查是否存在偏差,如果存在偏差,找出原因并在下一个循环里做纠偏调整,确保实际成本进度与计划成本进度一致或在可接受的范围内。
Earned Value Method(EVM)is an important tool of integrated control in project management.It can monitor the cost progress jointly and achieve the purpose of effective control.However,in the application of earned value method,it is found that the traditional earned value method has the problems such as not distinguishing the critical path,and failing to give a project specific implementation plans.According to the problems existing in the traditional earned value method,the Second-level EVM is put forward combining with PERT technology to treat the activities of the key path and non-critical path differently.In combination with PDCA cycle,the planned cost and progress target is regularly checked to see if there is any deviation compared with the actual target.If there is deviation,it is necessary to find the cause and correct it in the next cycle to ensure that the actual cost schedule is in line with the planned cost schedule or in the acceptable range.
