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
估算計劃活動的成本涉及估算完成每項計劃活動所需資源的近似成本。成本估算包括識別和考慮各種成本計算方案。例如，在大多數(shù)的應用領(lǐng)域，普遍在設計階段多做些額外工作以降低執(zhí)行階段和產(chǎn)品運行時的潛在成本。成本估算過程考慮預期的成本節(jié)省是否能夠彌補額外設計工作的成本。成本估算一般以貨幣單位表示，以利于在項目內(nèi)和項目間進行比較。項目范圍說明書描述了項目的商業(yè)要求、理由、需求和當前邊界。它提供了關(guān)于在成本估算時必須考慮的項目需求的重要信息。

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
參數(shù)估算涉及在一個數(shù)學模型中利用項目特性來預測整體項目成本。模型可以是簡單的也可以是復雜的。
