DECISION SUPPORT SYSTEM FOR WATER ADAPTING PRICING POLICY

In the paper, the conception of Enterprise Information Portal (EIP) as an enduser interface of Simulation and Modeling System for Business (SMS-B) is presented. The system is a proposition of Business Intelligence education platform. EIP portals are also a base for Enterprise Integration Platform (EIP II) introduction in information and communication system in an institution.

Enterprise Information Portal Implementation

This case study provides a detailed account of the formation of a knowledge management (KM) division within a multinational pharmaceutical company, and the subsequent undertaking of the first major KM project, which involved the implementation of a portal software technology. Specific issues discussed include rationale for replacing the existing intranet with portal technology, selection of the portal, justification for this selection, challenges in organizing and linking documents, as well as the social and behavioral factors influencing the implementation. A number of dilemmas and tradeoffs are presented with respect to each of the issues.

A Generic Model of an Enterprise Portal

With the rapid development of Internet technology, the portal has been envisioned as one of the greatest opportunities to improve the management of enterprise information. A number of portals associated with enterprise information portal, e-market portal, business portal, enterprise collaboration portal, enterprise knowledge portal, enterprise portal or enterprise information portal, etc. As one of the most important applications of portals, an enterprise portal is more attractive because it could be used not only to improve information management and business processes management (Collins, 2002; Detlor, 2004; Terra & Gordon, 2003), but also to promote business collaborations and interactions both internally and externally (Dias, 2001; Detlor, 2000).

Intelligent-Agent-Supported Enterprise Information Portal

Enterprises in today’s highly competitive environment must cope with mountainous information. At the same time, they must act quickly to make timely business decisions. Providing the right information at the right time has been a challenge for information technology professionals. Wells, Sheina, and Harris-Jones (2000) found that in the average company in the United States, 80% of information is kept on individual personal computers, and less than five percent of employee knowledge is captured and made available in enterprise systems. Various systems, such as management information systems, enterprise resource planning, and knowledge management systems have been used to support the information needs of organizations. In recent years, enterprise information portal (EIP) have been developed to provides an effective platform for knowledge workers in organizations to find, manage, use, and share previous disparate information. An EIP gives the user a single point of access to data, information, and knowledge across the entire enterprise, thus holding the promise of increasing the competitiveness of the organization (Mitchell, 2005; Schroeder, 2000).

Study on the Expended-Enterprise Information Portal Based on the Role Control Theory

Adopting the role-based access control solution, this paper focuses on the study of access level, the most important part of the enterprise information portal. In this paper, the original RBAC model was modified, methods such as domain and permission levels are applied to simplify and improve the access control, reducing the computation; client-side cache is adopted to improve the performance of the access control system. Finally, this paper uses the development of the portal modules to increase information portal functions, so that the needs of different users can be met.
