The Enterprise Market Investigation Data Analysis Method Research Based On Non-parameter GMDH

An important item of market investigation is the investigation data analysis. The market investigation data analysis causes the enterprise to know what the customer and the competitor is doing in market, and it is an important way promoting the enterprise competitive power. Because the market investigation data has characteristics with the small sample, the noise and many qualitative data, this article attempts to use the non-parameter GMDH method in the enterprise market investigation data analysis, hoping to provide a new effective way for the market investigation data analysis. This article does the work as follows:1. Reviewed the enterprise market investigation data analysis methods which have carried on at present.2. Analyzed the work principles of non-parameter GMDH, proved the validity of non-parameter GMDH used in the enterprise market investigation data analysis from the theory and the real diagnosis two aspects.3. Produced algorithm steps separately from non-parameter GMDH, including Self-Fuzzy Rule Induction using GMDH (FRI), Objective Cluster Analysis (OCA) and Analog Complexing(AC) used in the enterprise market investigation data analysis.4. Has carried on the improvement promotion to the FRI method. Replaced the standard type fuzzy model in FRI with the T-S fuzzy model, has established the GMDH model based on the T-S, and made the program to do real diagnosis research. The real diagnosis research has confirmed the GMDH model based on the T-S enhanced the market investigation data description ability with non-parameter GMDH.The innovations of this article mainly have:...
