上 Earned Value Concept Ei ◆问题: A project authorized amount is $100,000 over 12-month period. After six months of performance, the project spent $29,000 of its planned $32, 000 in budget. What can one discern from exam ining the performance at the half way of the project?

Earned value分析 ◆原理:C/ SCSc concept ◆BCWS:按基线计划到此的的预算成本 预算单价米预算工程量 ◆BCWP:已执行到比时的预算成本 预算单价*实际工程量 ◆ACWP:已执行到此时的实际成本 实际单价米实际工程量
原理: C/SCSC concept BCWS: 按基线计划到此时的预算成本 预算单价*预算工程量 BCWP：已执行到此时的预算成本 预算单价*实际工程量 ACWP：已执行到此时的实际成本 实际单价*实际工程量 Earned Value 分析
