A Process Algebra Software Engineering Environment

In previous work we described how the process algebra based language PSF can be used in software engineering, using the ToolBus, a coordination architecture also based on process algebra, as implementation model. In this article we summarize that work and describe the software development process more formally by presenting the tools we use in this process in a CASE setting, leading to the PSF-ToolBus software engineering environment. We generalize the refine step in this environment towards a process algebra based software engineering workbench of which several instances can be combined to form an environment

A LOTOS Framework for Middleware Specification

Abstract. This paper presents a LOTOS framework for the specification of middleware systems. The framework consists of a library of basic middleware components and some guidelines on how to compose them. The components of the framework facilitate the formal specification of different middleware systems

Software (Re-)Engineering with PSF II: from architecture to implementation

This paper presents ongoing research on the application of PSF in the field of software engineering and reengineering. We build a new implementation for the simulator of the PSF Toolkit starting from the specification in PSF of the architecture of a simple simulator and extend it with features to obtain the architecture of a full simulator. We apply refining and constraining techniques on the specification of the architecture to obtain a specification low enough to build an implementation from
