The application of the exponential smoothing method in the landslide treating engineering 指數(shù)平滑法在滑坡?lián)岆U工程中的應用
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 由于現(xiàn)金流量的波動性、隨機性、動態(tài)性等特性的存在,依靠單一方法無法科學、準確的預測現(xiàn)金流量。論文提出利用指數(shù)平滑和移動平滑的方法來剔除隨機因素影響,利用季節(jié)指數(shù)來消除現(xiàn)金流量的季節(jié)波動,之后再利用指數(shù)曲線或者多項式擬合曲線來預測整體現(xiàn)金流量的方法,并給出了整體現(xiàn)金流量的計算方法和確定原理。
