| Enterprise informatization process is changing constantly with computer communication and software technology development, and it becomes a trend that organizational decision always rely on computer communication and software technology, especially the information system/information technology adoption decision become an very important part to the development of the enterprise. ERP (enterprise resource planning) system is an important software carrier to the information technology development and implementation of enterprise informatization process, the determination of adoption decision factors help to analysis whether a ERP system have the ability to be on-line and whether it have a potential to be successful implementationEnterprise information technology decision is complicated; the influence factors of enterprise formation system adopted for different enterprises have different emphasis. There are quite a few problems in whether to accept the decision enterprise ERP system in the past, especially the probability of the implementation of ERP system is low. Some enterprise even have crisis for it. It is a very real problem that spends much money but can not improve production efficiency successfully. This research which discussed and analyzed the domestic and international computer information system/information technology concluded the trend of the future ERP system adopted decision-making possible development, and it researches the factors which influenced the computer system/software adopt decision theory TAM (technical accept theory) by ERP system. Secondly, extend the influenced factors which include by extended TAM theory, in view of the ERP system to make strategic management theory such as:SWOT model, the Delphi method (Delphi). Using fuzzy analytic hierarchy process (FAPH) to conclude the key factors which affect ERP system adopted, in order to solve the problems about the implementation process which will happen in the future. This will greatly improve the will and the actual behavior of using ERP system about the enterprise adopt decision; Thirdly, respectively take FAHP+GIOWA operator and fuzzy functional mapping method to research the ERP system adopted decision, and puts forward detailed proof and solutions. Finally, it analysis the key elements of the ERP system adopted decision which is influenced by enterprise from the social network and strategic decision perspective.According to the tendency of the problem to vivificate the factors which impact the enterprise information system adopted decision in many angles and many methods. There are some certain differences about the key factors when we using different perspective and research methods, and that absolutely can not be completely consistent, sometimes there will be a world of difference. It mainly lies in that many selected factors are subjective behavior, not objective selection. In other word, everyone have its own opinions even on the same problems. The content research means:one is to summarize the adopted key elements of ERP system by the theory research methods; the future we may verify it by the questionnaire, and according to different research purposes use different statistical analysis software, such as:SPSS, SAS, AMOS, EQS, Matlab, etc. Secondly, in the uncertain decision condition, building mathematical model, and elaborate by three different mathematical model:(1) using evidence theory (Dempster-Shafer theory, referred to as the DS theory) relatively well solve the uncertain factors of fuzzy decision in the strategic decision process and in order to deal with the problem of evidence conflict, solve the effective evidence synthesis, so when the enterprise makes a information decision that they can easily based on Delphi method, SWOT mode, so as to avoid the mistakes in the process of implementation and make the informatization implementation successfully, then can enhances the performance of the enterprise. At the same time, it is on the premise of the theoretical analysis puts forward theory frame of the enterprise using the compulsory and voluntary consultation and mixing conditions organization, group and individual three dimensional and further suggests that ERP system ado enterprise maybe difference in different state. Because of the ERP adopt decision itself is for the enterprises to improve efficiency and performance, to ensure implementation of the successful, we must consider different situation which can avoid the major mistakes in the process of implementation. Then we can make the informatization implementation successful as far as possible so that reach the targets of the enterprise (2) using fuzzy functional mapping method construct the key factors of ERP system adopted decision, and put forward the detailed proof of principle;(3) the FAHP+GIOWA method further improved the GIOWA operator used in ERP system adopted decision professor put forwarded by professor Xu. Thirdly, from social network relation and strategic decision Angle to analysis and empirical analysis the social capital of enterprise, strategic inertia factors on enterprise performance roles and relationships, as well as the influence to the enterprise ERP system adopted decision. Explaining the positive correlation to the enterprise social capital and strategic inertia significant, and then the strategic inertia and the enterprise performance shows the nonlinear U relationship, then it verifies the importance of the social network relation and strategic decision factors on enterprise. At the same time, whether or not to accept the importance of decision making and at the same time it also shows that it is one of the key factors to ERP adopt decision.This research breakthroughs many past theories, it analysis the key factors which influenced the ERP system adopted through the various research methods, at the same time it include the uncertainty decision in the new method of the strategic theory. And it also explores many uncertain factors under the uncertain conditions, then forming a more reasonable adoption decision-making, so that promoting the adopted decision by the enterprise which adjust the measures to local conditions. We must choice the ERP system which fit ourselves, meanwhile provides feasible decision scheme for other management software adopt decision. |
