工程项目管理中，已完成工作预算费用（BCWP）与计划工作预算费用（BCWS）的区别是什么？ 已完工作预算费用就是2113按照实际5261的工程量，在不知道实际费用的前提下估计花费4102的费用1653。计划工程预算费用就是按照计划的工程量，在不知道实际费用的前提下估计花费的费用。因为预估费用的方法相同，两者之差就是已完工程量和计划工程量的差，反映的是工作进度的完成情况。BCWP大于BCWS 即前者所花费用高，说明前者工程量大，超额完成，进度提前BCWP小于BCWS 即前者所花费用低，说明前者工程量小，未完成计划工程量，进度拖延。这样说的已经很清楚了，明白了吗？
完成预算或优于去年同期的英语怎么说 这个不清楚。
