Technical value evaluation method and evaluation model of technical economic life

Abstract

The invention provides a technical value evaluation method and an evaluation model of technical economic life based on a fuzzy evaluation theory and substance-field analysis. During quantitative analysis, by using a cluster analysis method, a fuzzy comprehensive evaluation method and the like, a quantitative analysis model of a technical value evaluation index system is constructed; meanwhile, for a mark sheet of technical sharing rate adjustment coefficients, a fuzzy comprehensive evaluation model for quantification of qualitative questions is used, so the current mainstream technical value evaluation system becomes more perfect, and an evaluation effect is more scientific. According to a substance-field model, a commissioned evaluation technology is subjected to functional decomposition, a technical function which causes key influence on a technical value is determined, the development history and development tendency of the technical function are shown by using different S curves, the different S curves are fitted and automatically calculated by using Loglet Lab 2 software, and the economic life of the key technical function of the commissioned evaluation technology is determined, so that the economic life of the commissioned evaluation technology is determined.

Description

technical field [0001] The invention relates to a technical value evaluation method and an evaluation model of technical and economic life, in particular to a technical value evaluation method and an evaluation model of technical and economic life based on fuzzy evaluation theory and object-field analysis. It belongs to the field of technical economics. Background technique [0002] The current technology value evaluation methods are basically grafting mature asset evaluation methods directly into the evaluation practice of technology value, without in-depth consideration of the particularity of the technology itself, and without considering the application conditions of various asset evaluation methods in technology value evaluation. , application scope and setting of key indicator system to carry out in-depth research. Due to the large uncertainty and ambiguity in the quantitative analysis of the technical value evaluation index system, in the past when the income method,...
