In order to reduce the influence of bullwhip effect, sales data are applied to forecast orders of the next period instead of ordering data. Mobile agent is applied to achieve the sales data from retailers in the data preparation. And the converting approach from sales data of retailers to prediction data is proposed. Autoregressive and moving average (ARMA) model is introduced to forecast orders and a comparison amongst final prediction error (FPE), Akaike information criterion(AIC), Bayes information criterion(BIC) and Akaike's corrected information criterion(AICC) criterion is shown. The sample test verifies the superiority of AICC; therefore it is applied to identify ARMA order. Forecasting architecture is established and then the prototype system is tested, at last a case shows the orders prediction of the next quarter and verifies the effectiveness of the proposed method.展开更多

However, Haier Group has broken the ice since it entered the IEC/PACT commission in June 2005, lifting the curtain on international standardization of our national enterprises. And now, Haier is hosting the IEC/PACT annual conference in November 2007. Could you introduce it in detail?展开更多

Year 2006 is the year marking the 100th anniversary of the founding of International Electrotechnical Commission (IEC).IEC has kept close ties with international electrical and electronic products and their manufactures for nearly 100 years. As an integral part of electrical and electronic product portfolio, Household electrical product development has also been directly influenced by IEC.……展开更多

The paper reports in detail the survey on characteristics of residential electric consumption, in particular the air conditioning consumption. To optimize power system operation and expand power market, the paper concludes that power industry must learn to investigate, open up and adapt itself to power market economy.展开更多
