The success of enterprise information system(EIS) is crucial to align with corporate strategies and eventually attain corporate goals. Since one of the factors to information system success is system use, managerial efforts to measure the level of EIS utilization is vital. In this paper, the EIS utilization level is analyzed using system access log data. In particular, process sequence patterns and clustering of similar functions are identified in more detail based on a process mining method, in addition to basic access log statistics. The result of this research can be used to improve existing information system design by finding real IS usage sequences and function clusters.

In this study, we must investigate what the major success factors that should be considered before introducing to successfully achieve the goal of building enterprise information systems. To evaluate the factors significantly affecting among the success factors. This study is to present by analyzing the typical success factors affecting successful introduction of the system information to companies that lack sufficient information and reviews for the introduction of enterprise information systems.

21 century as the knowledge information anger society now our society industry of all fields the rolling stock maintenance conservative standardization enterprise where information anger is being turning out construction Ministry of Transportation supported with continuous development of the supply section substitution quantity information processing system which the information highway is quick and the Korean railroad technical research worker propelled the enterprise as the subjective agency, it contracted this for a vehicle field information anger system construction in link of the enterprise our construction and an agreement, information technique composed the consortium t9day and it propelled a system codevelopment. The SMSC who is a front-runner of Maj loach city railroad operation agency to 'here business relates with a vehicle field maintenance conservativeness an immediacy operation and generally and information anger it will plan it will integrate it will own jointly and business efficiency and in the dictionary an obstacle occurrence electromotive car maintenance conservative information and it will improve only maintenance conservativeness of preventive maintenance of the electromotive car it knows it will prevent to construct the maintenance conservative system of the preventive maintenance, it applied the RIMS project to sleep.

Shipbuilding and repairing enterprise has the characteristics of many hazards and accidents. Therefore, the safety management ability of shipbuilding and repairing MIS (management information system) must be effectively guaranteed. The verification on safety management is the necessary measure to ensure and improve the safety management ability of MIS. Safety verification can not only increase the safety of MIS, but also make early warning of potential risks in management to avoid the accidents. Based on the authoritative standards in the field of safety in shipbuilding and repairing enterprise, this paper applied modeling and verification method based on ontology to safety verification of MIS, extracted the concepts and associations from related safety standards to construct axiom set to support safety verification on MIS of shipbuilding and repairing enterprise. Then, this paper developed the corresponding safety ontology modeling and verification tool-SOMVT. By the application and comparison of two examples, this paper effectively verified the safety of MIS to prove the modeling method and the SOMVT can improve the safety of MIS in a much more effective and stable way to traditional manual analysis.

Very various intrusion by development of systems that is based on network is spread. To detect and respond this intrusion, security solutions such as firewall or IDS are bringing and management of security system that load these becomes more harder. Moreover, because environment of systems that require security is various, hard to manage establishing suitable security policy Therefore, need model about enterprise management of various security system and intrusion detection of each systems and response. In this paper, improve PBNM structure that manage wide network resources and presented suitable model in intrusion detection and response of security system. Also, designed policy-based enterprise security management system for effective intrusion detection and response by applying presented model to enterprise security management system.

E-commerce and business information systems are being introduced in most of enterprises with the development of internet recently. Meanwhile the introduction of enterprise portal concepts and the enterprise informatization provide a necessary premise for insuring a competitive power. Therefore, it became necessary to research on the project of reusing the data of e-commerce. In this paper, we make a domestic maker the subject and implement a XML based electronic catalog(e-catalog) system for electronic commerce(e-commerce) based on web. The implemented XML based e-catalog system can reduce time and expenses needed for making, keeping and distribution in paper catalog systems. It also can correct the data reuse problems in the e-catalog systems implemented by HTML. Exchanging and reusing data used in e-commerce is essential to the integration between business information systems and points to the enterprise portal.

Nowadays, for the competitive power of an enterprise, there are many attempts to implement information system that could support business innovation by business process re-engineering. However, there is no effort to standardize the core business processes of enterprise based on standards of data, documents. These facts make it difficult to introduce and implement enterprise information system designed by business processes of the higher level. Therefore, standardization of business process by analyzing the functionality and relationships among them are important and necessary. The results of our research are summarized as process-driven standardization (standardization of core business processes) and development of a repository. In process-driven standardization, we proposed the reference model by analyzing the business processes of the leading enterprises for core business processes. The reference model focuses on core business processes, such as sales management, procurement management, production management, logistics management, and customer support in manufacturing industry. We developed a knowledge-based system as a repository for a integrated management system of business process. And this repository was built up web-based system for the purpose of both reference and management.

To develop an Enterprise Data Model in Information Strategy Planning, it is essential that we first decide on the critical entities that need to be consistently managed in the enterprise. Identifying entities is a very crucial decision that has much influence on the subsequent phases in Information Engineering. Nevertheless, it is very subjective and usually depends on a decision makers experience and his/her own knowledge. In this paper, we propose a decision support system called CB*IMSS, which employs Case-Based Reasoning as the problem solution technique. By retrieving, analyzing and adapting some similar previous cases with a decision makers enterprise situations, this system can help them identify and decide the critical entities required for successful performance of the ISP.

The importance of reliability information management for an effective product quality management has been increased. Reliability management requires many different kinds of human and technical expertise and cost over the various discipline in the organization. However, it is difficult task to set up appropriate and effective life data analysis because of lacking engineers with reliability knowledge, statistical background and of funds in small and medium-sized enterprise. It is needed to develop a low cost implementation architecture of reliability information supporting system for small and medium-sized enterprise under web environment. In this paper, research efforts are presented to solve such problems of small and medium-sized enterprise under web environment.
