多项目资金流预测对水电工程项目业主做出投资决策、安排进度计划具有重要意义,而资金流预测的关键问题是建立简单易用的资金流出计算方法。模型对水电工程进行项目划分,以单位工程和S曲线方程作为资金流预测的基础,利用历史相似工程的实际成本数据,采用回归分析的方法,估算在建工程的成本曲线;再考虑具体的合同条件、付款时间差等影响因素,得出实际的资金流出曲线。经算例验证,该方法可满足多项目资金流预测的要求。 The multi-project cash flow forecasting is of great significance to the hydropower project owner to make the investment decision and arrange the schedule. The key problem of the capital flow forecasting is to establish a simple and easy method of calculating the outflow of capital. The model divides the hydropower project, and takes the unit project and the S curve equation as the basis for the capital flow forecasting, and uses the actual cost data of the historical similar project and uses the regression analysis method to estimate the cost curve of the construction in progress. Then, the concrete contract Conditions, payment time difference and other influencing factors, come to the actual outflow of funds curve. The example verified that this method can meet the requirements of multi-project cash flow forecasting.
