Study On Evaluation Methods And Application Of Enterprise Informatization Level Based On Fuzzy Multi-Attribute Decision Making

With the rapid development of information technique, global informatization process is speeding up. Informatization has become the tremendous impetus for upgradation of industrial structure, improvement of labor productivity, and economy promotion. In fact, enterprise is the main body of informatization and to evaluate the enterprise informatization is an important part of enterprise informatization construction.Through inheriting, analyzing and developing the related enterprise informatization theory, informatization evaluation index system and evaluation method at home and abroad, this paper carries out systemic and in-depth study on enterprise informatization evaluation index system and evaluation method. The main contents of this paper are as follows:(1) Review related theories of enterprise informatization, including connotation, characteristic, content, level, stage and effect of enterprise informatization.(2) Study quantifiable representation method of qualitative index, transform methods to convert linguistic variable into interval number, triangular fuzzy number or trapezoidal fuzzy number, operation rules and normalized method of different data types.(3) Construct systemic evaluation index system of enterprise informatization, including information infrastructure, informatization strategy and construction of information organization, construction of talent for enterprise informatization, application of enterprise informatization, benefit of enterprise informatization these five first-level indexes and 24 second-level indexes.(4) Study combination weight involving subjective weight and objective weight. In the aspect of subjective weight, this paper constructs subjective weight determination models, such as improved AHP method based on interval number, triangular fuzzy number and linguistic variable; in the aspect of objective weight, this paper constructs five hybrid decision matrix objective weight determination models based on entropy weight, maximizing deviations, variation coefficient, grey correlation and projection pursuit model; in the aspect of combination weight, this paper constructs three combination weight determination methods by maximizing comprehensive evaluation values, minimizing total deviation and integrating combination weight. (5) Based on hybrid data types, this paper studies improved TOPSIS method, improved grey correlation method, improved projection method, improved ELCETRE method and two-tuple linguistic evaluation method by converting different data types into linguistic variables, and ordered weighted integrated method. Moreover, this paper introduces the evaluation principles and evaluation steps of above methods in detail.(6) Carry out an empirical study on enterprise informatization levels of nine industries in Shandong province, and adopts improved TOPSIS method, improved grey correlation method, improved grey correlation projection method, improved ELCETRE method and two-tuple linguistic method to respectively rank nine industries according to their informatization levels, then makes a comparison among these methods, and finally uses Borda method to sort nine industries in Shandong province by informatization levels.(7) With regard to further construction of enterprise informatization in Shandong province, this paper gives some suggestions on two aspects including government's macro-management system and enterprise informatization construction.
