The Hierarchic Grey Incidence Analysis Model With Fixed Weights and Its Application to a Regional Scientific-technical System

The grey incidence analysis (GIA) is one of the most important methods for realizing system analysis. In order to conquer the limitations of the existing GIA model, which can be effectively applied to the simple system with one-hierarchy correlation factors and one main behavior character only, not to the complex system with multi-hierarchy correlation factors and multi behavior characters, the weighted synthetic method of calculating abstract incidence degrees between the system behavioral characteristics and correlative factors in different hierarchies is proposed, then the hierarchic grey incidence analysis (HGIA) model with full consideration to the difference of different character importance, and to the relationship between factors in different hierarchies, is established. The effectiveness and application of the HGIA model are tested by the scientific-technological system of Jiangsu province as a positive example. The depth and the range of the application of GIA are developed
