‎In this paper‎, ‎the numerical solutions of linear and nonlinear Volterra integral‎ ‎equations with nonvanishing delay are considered by two methods‎. ‎The methods are developed by means of‎ ‎the sinc approximation with the single exponential (SE) and double exponential (DE)‎ ‎transformations‎. ‎The existence and uniqueness of sinc-collocation solutions for these equations are provided‎. ‎Thes...

the medium density fiberboard (mdf) market demand was investigated during the years from 2004 to 2013 in iran. estimation of mdf demand was made by exponential smoothing method by the year 2018. the insight into the level of demand that might exist by the year 2013 was obtained by reviewing the production, import, export, and consumption of mdf on the iran. the results show that the consumption...

We present an experiment comparing double exponential smoothing and Kalman filter-based predictive tracking algorithms with derivative free measurement models. Our results show that the double exponential smoothers run approximately 135 times faster with equivalent prediction performance. The paper briefly describes the algorithms used in the experiment and discusses the results. 1 Double Expon...

Abstract—The aim of this paper is to select the most accurate forecasting method for predicting the future values of the unemployment rate in selected European countries. In order to do so, several forecasting techniques adequate for forecasting time series with trend component, were selected, namely: double exponential smoothing (also known as Holt`s method) and Holt-Winters` method which acco...

Dr. Thomas C. Chiang LECTURE 2 MOVING AVERAGES AND EXPONENTIAL SMOOTHING OVERVIEW This lecture introduces time-series smoothing forecasting methods. Various models are discussed, including methods applicable to nonstationary and seasonal time-series data. These models are viewed as classical time-series model; all of them are univariate. LEARNING OBJECTIVES • Moving averages • Forecasting using...

Commodity prices forecasting is one of the business functions to estimate future demand based on past data trend. This study aims implement a trial and error technique constant (alpha α) value in exponential smoothing method. Dealing with confusion that often researchers find selecting an alpha (α) among families, which suits characteristics investigated case. As selection precisely contributes...

The importance of the measles immunization vaccine for children up to age 9 months prevent from getting sick with or reduce transmission rate in surrounding environment, especially at Gambir Health Center. This demand is still considered ineffective and there often an oversupply vaccines, which results a buildup vaccines storage. purpose this study was create needs forecasting system using Sing...
