System Analysis And Evaluation Of IT Value During The Progress Of Enterprise Informationazation

Currently, the trend of society informationization and economic globalization is more and more evidence. So informationization is one of import means of inform and development of enterprise. From the view of technology economics and system science, using management, statistic economics, microeconomics, computer science and game theory and methods of statistic analyses, DEA, AHP, and fuzzy comprehensive evaluation method, this paper analyzes and estimates the value of information technique during the enterprise informationazation. There are three parts, including theoretical research, value analysis and value evaluation, in this paper, except preface and conclusion. The main job of all parts is as following.The first part, including the second chapter, is theoretical research. This part mainly researches many literatures about the influence factor of IT value and evaluation of IT value etc, and then introduces the correlative theory to this paper. The second part, including the third chapter, is value analysis. In this part, by the system analysis to produce process of IT value, the paper divides the producing process of IT value into four stages, diffusion stage, digestive stage, absorbability stage and fusion stage, and then analyzes the characteristic of all stages. The third part, including the fourth the fifth and the sixth chapters, is value evaluation. From five aspects, that of the diversity of value, the indivisibility of value, the condition of coming value, the otherness of estimatorand and the localization of evaluation method, this paper analyzes influence factor of IT value evaluation and summarizes all kinds of difficulties to face on IT value evaluation. Furthermore, it designs the evaluation model to evaluation tangible value of IT according to DEA method and the evaluation model to evaluation intangible value of IT basing on fuzzy comprehensive evaluation method.The main innovations in this paper are as following, it divides the producing process of IT value into four stages, and summarizes five aspects of complexities of evaluation, and thinks influence to organization structure, business flow, organization scale and organization boundary as neutral value, and researches some tangible and intangible value of IT to large electronic manufacture enterprise and get some important meaning conclusion.
