The essentiality of human information system interaction efficiency was analyzed under the computerization environment of enterprises. Information processing ability was measured from three dimensions: working memory, cognitive skill, and computer self efficacy. The experimental method was used to study the influence of information processing ability on human information system interaction efficiency. Multiple regression results show that cognitive skill is the main factor influencing interaction efficiency for skill based tasks, working memory is the main factor for rule based tasks, and working memory has no significant influence on interaction efficiency for knowledge based tasks. Working memory and computer self efficacy are the main factors influencing interaction efficiency for total tasks. 相似文献

Information integrating is the most important key to CIMS,which is the base of the function integrating and all others.Because of so many kinds,so complicated structure,so many different sources and uses that the information in CIMS has,it is necessary to build a popular Information Integrating Model. The model of information integrating in the thesis bases on the enterprise model,which is presented by ISO(International Organization for Standardization).According to the object-oriented method,the process of modeling begins with classifying the information,and then describes the definition of the attributes and the structural relation of those objects. By means of the idea of Encapsulation and Inheritance,the destination of information integrating can be arrive and the model of information integrating can be set up. The model which is based on the share information is helpful to finish the function integrating and the whole CIMS' construction. Moreover,the system which is developed following such program can be reused for many times and the developing circle of CIMS can be apparently shortened,too. 相似文献

Information system audit is a product of combining both information technique and audit. Its generalized application can normalize the running of information system for various industrial department over whole life circle under the condition of high speed development, reduce information risk,and also guarantee profit to enterprise.Aiming at the different understanding on ISA generally used in China,we analyze and compare the difference between ISA and CAA(computer assisted audit),such as meaning,object,content,technique,method and operator,and so on.The paper shows that both ISA and CAA should be developped in audit field,that ISA is a new kind of audit to be different from CAA,and that there exists some disadvantage by means of computer audit summarizing CAA and ISA,so it is necessary to speed up to develop ISA. 相似文献

There exists the information asymmetry between banks and enterprises that need loan, which can cause the problem of adverse selection. With the symmetry information, banks and enterprises can manage to reach best contracts. However, with the information asymmetry, when banks select the price of loan according to the average risk level of borrowers, the problem of adverse selection appears. Mortgage and guarantee are all very helpful to deal with adverse selection in some sides. For example, guarantee can send a signal to banks that enterprises could be low risky, and mortgage can make highly risky enterprises give up borrowing since it will bear more responsibility for its fail. A form of contract that connects the price of loan with the value of mortgage can help to recognize the style of different borrowers. 相似文献
