Risk early warning index system based on D-S evidence synthesis technology

Abstract

The invention discloses a risk early warning index system based on a D-S evidence synthesis technology. The system comprises an enterprise information acquisition module, a data receiving module, a data analysis module, a result export module, a model building module, a model comparison module, a model library, an index generation module, a master control module, an information sending module, a database, a login module, an identity verification module and an alarm sending module, wherein the enterprise information acquisition module is used for acquiring enterprise information, and the enterprise information comprises enterprise operation range information, enterprise establishment time information, enterprise profit information in previous years and enterprise scientific research input information; the data receiving module is used for receiving enterprise information and sending the enterprise information to the data analysis module; and the data analysis module analyzes the enterprise information through a D-S evidence synthesis technology to obtain first risk early warning index information. According to the invention, the obtained risk early warning is higher in accuracy and higher in reference value.

Description

technical field [0001] The invention relates to the field of risk early warning indicators, in particular to a risk early warning indicator system based on D-S evidence synthesis technology. Background technique [0002] D-S evidence synthesis technology is an imprecise reasoning theory, also known as Dempster / Shafer evidence theory (D-S evidence theory), which belongs to the category of artificial intelligence. It was first applied in expert systems and has the ability to deal with uncertain information. As an uncertain reasoning method, the main characteristics of evidence theory are: satisfying weaker conditions than Bayesian probability theory; having the ability to directly express "uncertainty" and "don't know"; [0003] D-S evidence synthesis technology is also used in the process of generating and calculating risk warning indicators. [0004] In the existing risk early warning indicator system, the types of early warning indicators generated are relatively single, w...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: how to solve the existing risk early warning index system, the generated early warning index type is relatively single, resulting in the generated early warning index reference is not high enough, and the accuracy is not high enough, which brings a lot of problems to the use of the risk early warning index system. To solve the problem of certain impact, it provides an early warning index system based on D-S evidence synthesis technology risk
