Recent history is filled with stories of companies and sometimes even entire industries that have made grave strategic errors because of inaccurate industrywide demand forecasts. For example: In , U. Such forecasts are crucial […]. For example:. The inaccurate suppositions did not stem from a lack of forecasting techniques; regression analysis, historical trend smoothing, and others were available to all the players. Instead, they shared a mistaken fundamental assumption: that relationships driving demand in the past would continue unaltered.

In order to forecast prices of arbitrary agricultural commodity in different wholesale markets in one city, this paper proposes a mixed model, which combines ARIMA model and PLS regression method based on time and space factors. This mixed model is able to obtain the forecasting results of weekly prices of agricultural commodities in different markets. Meanwhile, this paper sets up variables to measure the price changing trend based on the change of exogenous variables and prices, thus achieves the warning of daily price changes using neural networks. The model is tested with the data of several types of agricultural commodities and error analysis is made. The result shows that the mixed model is more accurate in forecasting agricultural commodity prices than each single model does, and has better accuracy in warning values. The mixed model, to some extent, forecasts the daily price changes of agricultural commodities. The fluctuation of agricultural commodity prices is affected by economic and social factors.

Пока файл Цифровой крепости не подменен модифицированной версией, копия ключа, находившаяся у Танкадо, продолжает представлять собой огромную опасность. - Когда мы внесем эту поправку, - добавил Стратмор, - мне будет все равно, сколько ключей гуляет по свету: чем их больше, тем забавнее.  - Он жестом попросил ее возобновить поиск.  - Но пока этого не произошло, мы в цейтноте. Сьюзан открыла рот, желая сказать, что она все понимает, но ее слова были заглушены внезапным пронзительным звуком.

Я сказал ему, что японец отдал свое кольцо - но не. Да я бы ничего и не взял у умирающего. О небо. Только подумайте. Беккер встревожился: - Так кольца у вас. - Боже мой, конечно. Беккер ощутил тупую боль в желудке.
