Based on the two-level supply chain composed of suppliers and retailers, we assume that market demand is subject to an ARIMA(1, 1, 1). The supplier uses minimum mean square error method (MMSE), simple moving average (SMA) weighted (WMA) respectively forecast demand. According statistical properties stationary time series, calculate between Through simulation, compare forecasting effects three m...

in this article, the effectiveness of eight different technical indexes including simple moving average, weighted moving average, exponential moving average, relative strength, commodity channel, stochastic, money flow and demand are examined by comparison between indexes returns with buy and hold returns. the results shows the return of buy and hold strategy is more than technical indexes in t...

Due to the instability of characteristics materials, fabrication processes and user handling, newly designed fabricated wireless passive surface acoustic wave (WP-SAW) sensor nodes have inconsistent sensing performance. Furthermore, ambient environmental interferences aggravate inconsistences under complex working conditions. In this paper, a multi-iteration enhanced two-point simple moving ave...
