Estimating schedule activity costs involves developing an （-） of the cost of the resources needed to complete each schedule activity. Cost estimating includes identifying and considering various costing alternatives.for example,in mostapplication areas,additional work during a design phase is widely held to have the potential for reducing the cost of the execution phase and product oprations. the cost estimating process considers whether the expected savings can offset the cost of the additional design work. cost estmates are generally expressed in units of （-） to facilitate comparisons both within and across projects. the （ ） describes important information about prject requirement that is considered duing cost estimating.
A、project scope statement
B、statement of work
C、project management plan
D、project policy
估算计划活动的成本涉及估算完成每项计划活动所需资源的近似成本。成本估算包括识别和考虑各种成本计算方案。例如，在大多数的应用领域，普遍在设计阶段多做些额外工作以降低执行阶段和产品运行时的潜在成本。成本估算过程考虑预期的成本节省是否能够弥补额外设计工作的成本。成本估算一般以货币单位表示，以利于在项目内和项目间进行比较。项目范围说明书描述了项目的商业要求、理由、需求和当前边界。它提供了关于在成本估算时必须考虑的项目需求的重要信息。

The （ ） technique involves using project characteristics in a mathematical model to predict total project cost.models can be simple or complex.
A、cost aggregation
B、reserve analysis
C、parametric estimating
D、funding limit reconciliarion
参数估算涉及在一个数学模型中利用项目特性来预测整体项目成本。模型可以是简单的也可以是复杂的。
