合同项目费用／进度绩效模型研究

分析工程建设项目费用／进度控制的基本原理，指出预算计划值、实际值、赢得值得研究费用／进度控制系统行为状态的3个重要参数。结合国际工程中工程师概算的费用组成，提出合同项目费用／进度绩效模型。详细研究了单价计价活动、合价计价活动、计日工活动及暂定金费用项目的预算计划值、实际值、赢得值，给出相应的计算方法及公式，并建立起各类活动（费用项目）预算计划值设置模块、实际值统计模块、赢得值度量模块。在此基础上，建立起合同项目预算计划值设置模块、实际值统计模块、赢得值度量模块。其结果为费用绩效、进度绩效、综合绩效等行为状态的研究奠定了基础。

Cost/schedule models for contract works

The basic principles of cost/schedule control for works were analyzed, and it was pointed out that the Budget Cost for Work Scheduled (BCWS), the Actual Cost for Work Performed (ACWP), and the Budget Cost for Work Performed (BCWP) are three important parameters for the research of the behavior states of cost/schedule control systems. A cost/schedule performance model for contract works was put forward in combination with the composition of the engineer's budget cost estimate in international projects. Besides, BCWS, ACWP, and BCWP of unit price activity, lump sum activity, day work activity, and provisional sum item were studied in detail, and corresponding calculation methods and formulae were given. Furthermore, models for BCWS arrangement, ACWP counting, and BCWP measurement for each activity (cost item) were developed, providing a basis for research of cost performance, schedule performance, and comprehensive performance.
