Technology Breakdown Structure Method Study Based On The Co-Word Analysis

Since 1990s, with the upcoming of the New Economic Era featured as the knowledge explosion, accelerated diffusion and globalization of technology, the emerging technology based on IT, Bio Technology and so on had been shortening the time interval between the laboratory and the market. Each breakthrough of the technology has brought people with a revolutionary change. It is a critical factor for a developing county to identify the technology and enter the new area of the it as soon as possible.This thesis proposes the Technology Breakdown Structure (TBS), and makes the judgment and analysis of the TBS from the angle of co-word analysis. In order to reduce the complexity of the technology in part, the complicated technology is broken down into some simple child-technology for analysis, and the constructing framework of the TBS based on co-word analysis is established. At first, using the documents retrieving tools, the technology document are retrieved. The using the Law Zipf, the keywords are abstracted and the number of the keywords is determined by the Formula Keywords Abstracting. Thirdly, the keyword co-relative matrix is created based on the inclusion index. At last, by analyzing the co-relative matrix using multi-state statistic analysis, the final Technology Breakdown Structure is achieved.Using a demonstration research on the Smart Grid, the ETBS evaluation framework is validated.
