Embodiment 1
[0056]The regional grain and oil market price monitoring analysis and prediction system of the present invention includes a database, an input module, a report data generation module, a basic price query module, a summary statistics release module, an early warning monitoring and analysis module, and a system performance evaluation module. The database is multiple Dimensional database architecture; such as the use of a multi-dimensional virtual data warehouse composite architecture, which breaks away from a single traditional relational logic database architecture to achieve multi-dimensional data collection and analysis; enables the unique functions of a multi-dimensional database to store data in a relational database In order to manage, conveniently collect the data of each monitoring station, and keep the real and useful data for decision-making. The input module includes a price input unit and a price review unit to input price collection data to the database; The report d...

[0069] The monitoring system of the present invention also includes a price index analysis module, which is used to intercept the wholesale and retail price and quantity data of the grain and oil price monitoring system according to the regional grain and oil price index base period and variety and its weight, to form the corresponding grain and oil variety index and comprehensive index and Graphically, index tables and trend charts are finally formed; at the same time, the national grain and oil price index is imported to obtain, and the comparison between the whole country and specific regions, such as the Tianjin index, provides services for intuitive understanding of the national and Tianjin grain and oil price levels and trends. In the price index analysis In this paper, a scientific and reasonable grain and oil price index analysis model is established, and the weight of each grain variety is adjusted in time according to the transaction quantity and market price of each g...

[0085] The described early warning monitoring analysis module includes a wholesale price prediction model, which is based on a time series analysis method for actual prediction, and is extrapolated according to the difference sequence dy in the wholesale price time series Y, where Yt is a certain grain and oil product in a certain month, such as wheat The wholesale price of ; that is, t is the month specific to a certain year.
[0086] Y t =Y t-1 +dy t in,
[0087] dy t =-13.56-0.2816dy t-1 -0.3196dy t-2 ;
[0088] dy t-1 =Y t-1 -Y t-2 ;
[0089] dy t-2 =Y t-2 -Y t-3 ;
[0090] Referring to the relevant historical data, we forecast and calculate the error on the wholesale price of wheat in Tianjin.
[0091] The wholesale wheat price values for December, November and October 2002 are 1160, 1140 and 1140 respectively, namely:
[0092] dy 2002.12 =Y 2002.12 -Y 2002.11 =20
[0093] dy 2002.11 =Y 2002.11 -Y 2002.10 =0
[0094] According to the formula dy ...
