季节指数 meaning in Chinese
seasonal index number
Examples
- A forecast model of monthly electric power demand based on season exponent and grey forecast
基于季节指数和灰色预测的月电量预测模型 - Due to the existing volatility , stochastic and dynamic properties of cash flow , this paper employs exponential smoothing method and moving average method to eliminate the effects of the stochastic factors , use the seasonal exponent to eliminate the seasonal volatility of the cash flow , the exponent curve and polynomial fitting curve to estimate the overall cash flow and also provides the calculating methods and identifying principle of the overall cash flow
由于现金流量的波动性、随机性、动态性等特性的存在，依靠单一方法无法科学、准确的预测现金流量。论文提出利用指数平滑和移动平滑的方法来剔除随机因素影响，利用季节指数来消除现金流量的季节波动，之后再利用指数曲线或者多项式拟合曲线来预测整体现金流量的方法，并给出了整体现金流量的计算方法和确定原理。 - The paper analyze many methods of water demand prediction which include many up to date methods and some in common use , and it bring forward some new combinatorial methods which can meet the need of optimization model in precision , such as season exponent , auto adapt filter , season exponent combined grey model , etc . based on the cost and time of modeling jt mainly study the macroscopic network model which describes the correlation between nodal pressures and water plant discharge
针对时用水量预测模型，采用季节指数法、自适应指数平滑法、季节指数联合自适应过滤法、指数平滑联合自回归法、季节指数联合灰色系统法等具体预测方法，其中数种方法预测精度达到工程要求。实践结果表明，开发的联合法效果较好。考虑到管网宏观模型不但能描述整个管网的工作状态，而且建模所需成本低，运行速度快，省时省力，主要研究了管网宏观模型的建立方法，分析测压点布置原理并编制程序。
