Three basic parameters of the law of earning value: A budget expenses (BCWS) which plan the work load. Promptly according to sanction approved progress plan and budget get some work necessary accumulative total value that injected capital into that point should finish for the moment planned costs, it means planning the project to measure and budget for the sum of the product of the unit price. It's time, worth, weigh project progress and project one scale or basis of expenses. BCWS refers to in the course of project implementation some periodic plan requires budget man-hour (or the expenses) when the work load finished needs. Formula: BCWS =The work load of the plan is budget quota *. BCWS mainly reflects work load instead of reflecting man-hour (or the expenses) that should be consumed that the progress plan should be finished. For example: Plan to install a WEB and insert the server, estimates hardware, software, installation,etc. plan in one week in some project, buy the software and hardware and cost budget of asking others to install etc., has sanctioned 30,000 yuan. The budget expense BCWS of planning work of this week is 30,000 yuan.

挣值法的三个基本参数：
1计划工作量的预算费用(BCWS)。计划成本即根据批准认可的进度计划和预算到某一时点应当完成的工作所需投入资金的累计值，它等于计划工程量与预算单价的乘积之和。该值是衡量工程进度和工程费用的一个标尺或基准。
BCWS是指项目实施过程中某阶段计划要求完成的工作量所需的预算工时(或费用)。
公式：BCWS=计划工作量×预算定额。
BCWS主要是反映进度计划应当完成的工作量而不是反映应消耗的工时(或费用)。例如：某项目打算安装一台WEB接入服务器，预计硬件、软件、安装等计划用一周的时间，购买软硬件及请别人安装等的成本预算，批准了3万元。这一周的计划工作预算费用BCWS就是3万元。�
