The Linear System Analyzer (LSA) is a component-based problem-solving environment (PSE) for the manipulation and solution of large sparse linear systems of equations. Both the underlying component infrastructure and its application to the problem area of linear systems are introduced. Initial results indicate the utility of clearly separating the PSE infrastructure from the particular problem d...

This paper describes a new computing paradigm known as a problem solving environment ~PSE!, explores the role this new paradigm might play in watershed management and land use change analysis, and compares PSEs to similar technologies such as decision support systems and geographic information systems. A prototypical watershed management PSE organizes and unifies the diverse collection of softw...

The process systems engineering (PSE) as well as the operations research and management science (ORMS) literature has hitherto focused on disparate processes and functions within the enterprise. These themes have included upstream R&D pipeline management, planning and scheduling in batch and continuous manufacturing systems and more recently supply chain optimization under uncertainty. In reali...

In this paper we explain how a Problem Solving Environment (PSE) can be constructed such that the computationally intensive sections are run using resources on the Computational Grid, operating remotely from the machine running the visualisation. The PSE in question is one solving demanding elastohydrodynamic lubrication problems from mechanical engineering. The numerical calculation is done he...
