[Abstract]:The accurate measurement of the complexity of information system is to solve the system cost estimation, reasonable pricing and maintenance optimization based on the existing research results or information system as a software system, the software code, to explore the complexity of the system structure or objects; or to expand the perspective of management information system, pay attention to the information system design, complex the degree of development, but the large number of research results, the complexity of operation and few scholars pay attention to information system. In order to make up for the defects of the current research, this paper based on the data perspective, put forward to design a comprehensive measure of enterprise information system development and operation stage the complexity of the model and measurement methods, and provide reference and application exploration. The reference to the information system complexity theory research and practice management. In order to fully and accurately measure the complexity of enterprise information system In this paper, based on the representation theory, starting from the data of information system connotation, puts forward the concept of "data complexity", construct the corresponding theoretical model; the model development and the corresponding measure of complexity measurement tool based on the proposed model; and the traditional measurement method and model method are validated to demonstrate the effectiveness of the model and method; on this basis, through the empirical data of the 7 manufacturing enterprises 162 information system analysis, verify the enterprise information system to maintain data complexity of price influence; finally design based on dynamic data complexity adaptive maintenance strategy. The main contents are as follows: (1) put forward the "data complexity". The concept and construct a theoretical model. Focusing on "what is the nature of information system? Whether can combine its essence to explore its complexity? Include what?", base In the data representation theory in view of the real world embodies the concept of characterization analysis, put forward the "data complexity" concept, then, on the basis of the three hypotheses theory of representation model will be divided into specific data model, data operation range, the four dimensions of the intensity and amount of data operation, analyzes the relationship between the data complexity and effective application well, the driving factors of the complexity of enterprise information system, and discusses the theoretical contribution of this model. This model may expand the application field of representation theory, which is a new perspective of the complexity of information. (2) the data complexity of enterprise information system. The data measure around the "complexity of information system can be quantitative measurement? How to measure?", combined with information entropy and complex character space theory, the design of measurement model and measurement method of enterprise information system based on data complexity, and According to the development of a set of effective data complexity measurement tools, data complexity and using the tools of enterprise applications and e-government information system and application of two types of calculation respectively, analysis results show that, first, business features and characteristics of the complexity of enterprise data consistent with this characterization coincides with the theoretical assumptions; secondly, the amount of data complexity of operation period of contribution to the overall complexity of the larger, highlights the model can reflect the characteristics of the operational phase of the advantage, finally, compared to the effect of the enterprise information system, the complexity of data operation of e-government system on the whole more embodies the application of e-government system more widely, characteristics of greater strength. (3) to verify the effectiveness of enterprise information system data complexity measure method. Around the "complexity measurement method of information system is effective?", the enterprise The architecture complexity measure complexity of information system data and the traditional measurement methods are compared and verified. The same information system through the comparison of 3 different companies (Management Information System) data complexity, longitudinal analysis of the same company in different information systems (material management information system and information system complexity, cost management) results show that the method for measuring data complexity of information system compared with the traditional measurement method, a measurement model is more comprehensive and dynamic evaluation method to consider more fully the advantages. (4) to explore the relation between data complexity and enterprise information system maintenance. Around the "complexity of information system will impact?" the problem, build enterprise information systems based on data complexity "design complexity - development complexity - operation complexity - maintenance price" Study on multi stage model, and verified by actual data of 7 large and medium-sized manufacturing enterprises of the 162 systems, the empirical results show that the data complexity, maintenance service level and the service time of the system can be significantly influenced the late maintenance price, on the basis of the conclusion, enterprises can to data from the perspective of complexity, maintenance of price model design more reasonable. (5) proposed the dynamic complexity of enterprise information system for maintenance strategy adaptability system based on "how to understand. Through the complexity of information systems, to provide help for the development of effective management measures?", constructs the dynamic complexity of data maintenance strategy based on space, and then through the dynamic complexity calculation 3 large and medium sized manufacturing enterprise material management system in the operation process, based on the maintenance strategy for space design maintenance strategy. The results show that based on The maintenance strategy developed by the analysis results can be more adapted to the business characteristics and can improve the service efficiency of the information system maintenance.
