In this article we analyze the bullwhip effect of weighted moving average forecast under stochastic lead time. Under a general setting we express a performance measure on bullwhip effect theoretically. Numerical results give effects of parameters of forecasting and the lead time distribution on the ...

英语翻译Moving averageOne,very simple,method for time series forecasting is to take a moving average (also known as weighted moving average).The moving average (mt) over the last L periods ending in period t is calculated by taking the average of
Additionally, we demonstrate that the proposed method works well compared with the Double Exponentially Weighted Moving Average (DEWMA), the Multiplicative Holt-Winters (MHW), and the Additive Holt-Winters (AHW) methods, which are suitably used for forecasting data with the trend and the ...

In this paper, we consider a class of weighted moving average models called the k-th moving average, the k-th weighted moving average and the k-th exponential weighted moving average models for modeling and forecasting economic time series data. Using real time series data set, we compare the...

Since the EWMA statistic also appears as the optimal forecasting method for some time series model and is easier to apply than the CUSUM chart, there is a lot of interest and consequently a substantial literature on EWMA charts. Klein (1996) obtained ARL profiles for both the composite Shewhart...
