| Summary: | 碩士 === 國立交通大學 === 資訊管理研究所 === 83 === The purpose of this study is tried to explorate the
characteristics of the linkage of products in of industry and
further more to develop a petrochemical industry relationship
based investment information system .The system is developed to
handle the fluctuation of the prices of petrochemicals and to
analyze the relationship between the upstream and downstream of
petrochemical industry. In order to achieve this goal two main
portions of this system are created in the research:the basic
date preprocess information system and a neural network model.
Firstly, three modules under the basic data process information
system shell are built : raw data collection, graphical
analysis and industry relationship analysis. The products
relationship between upstream and downstream obtained from the
petrochemicals is usually not sufficient enough or is so-call
semi-structural information.Secondly,a neural network model
which is used to connect in the our information system is
created to link or transform the influence of the trend of
activities of industry. Finally,a neural network based
petrochemical industry information system is built .And an
empirical study regarding to the SM,AN and SBR product series
is selected and analyzed in the system .The results is shown
how the new model can transform the influence of the
petrochemical products price,quantity and trend from upstream
to downstream and its corresponding statistical analysis.
