This paper provides an integrated framework for portfolio selection, which is adaptable to the needs of financial organizations and individual investors, and as an organized approach of selecting efficient portfolios for investments. The authors focus their discussion on the implementation of this framework for a Web-based Decision Support System (DSS) based on their prototype named WPSS - A Web-based Portfolio Selection System for Chinese financial markets. In this system, the authors adopt technologies such as online analytical processing as an add-on tool for analytical purpose, as well as using Parallel Virtual Machine (PVM) to improve overall performance.
