Method and device for predicting micro-area flow parameters

Abstract

The invention discloses a forecasting method and device for flow parameters of micro areas. Firstly, the time series of fixed parameters A and the time series of flow parameters B of a macro area are collected; secondly, according to the relation between the macro area and each micro area, the time series of fixed parameters A of each micro area is obtained; thirdly, by means of a state equation of extended Kalman filtering, the relation between the time series of the fixed parameters and the time series of the flow parameters B is obtained; fourthly, by means of the obtained relation between the fixed parameters A and the flow parameters B, a forecasting value of the time series of the flow parameters B of each micro area is obtained; finally, according to the obtained time series of the fixed parameters A of each micro area and the forecasting value of the time series of the flow parameters B of each micro area, resource optimization is conducted on each micro area. The forecasting method and device change the black-box situation of the micro areas, the states of the flow parameters in the micro areas are forecasted, resources are utilized according to forecasting results, and therefore the resources are optimized; meanwhile, the extended Kalman filtering algorithm is used, the obtained results are accurate, the error rate is low, and very good application value is obtained.

Description

technical field [0001] The invention relates to the technical field of data mining, in particular to a method and device for predicting flow parameters in micro-regions. Background technique [0002] Existing technology cannot obtain the flow parameters (frequently changing data) of a micro-area (such as a small business unit such as a district) in a timely manner, and cannot understand the state of the flow parameters of a micro-area in real time. The micro-area has always been in a "black box" state, affecting micro Planning and implementation of various programs in the region. Contents of the invention [0003] Based on the above situation, the present invention proposes a method for predicting micro-area flow parameters, which can obtain the state of micro-area flow parameters and combine actual utilization of resources, which has good application value. [0004] In order to achieve the above object, the technical solution of the present invention is: [0005] A meth...
