Designing automation systems, as in most engineering endeavors, is primarily an architectural problem, involving hardware and software components. The objective of this paper is to introduce the concept of software architecture and styles in designing automation systems, and to describe an object framework for the development of global automation systems.

System development by reenements provides a number of advantages, notably correct derivation and documentation of design decisions. In this paper, we illustrate this position by introducing some reenement patterns that correspond to well known architectural styles: The application of a pattern in the development both guarantees the correctness of the step, and makes the architecture explicit.

To meet the demand and stay competitive, many systems were traditionally pieced together without much consideration given to their quality, modifiability, scalability, security, or maintainability. This has since littered the computing landscape with brittle applications with high maintenance and complexity. Over time, these maligned systems have propagated in size and merged or integrated to b...

Well, someone can decide by themselves what they want to do and need to do but sometimes, that kind of person will need some software design methodology from principles to architectural styles references. People with open minded will always try to seek for the new things and information from many sources. On the contrary, people with closed mind will always think that they can do it by their pr...

The quality of an architectural design of a software system has a great influence on achieving non-functional requirements to the system, so formal evaluation and validation techniques to designed architectures are necessary in the early phase of development processes. In this paper, we present a technique for describing software architectures formally based on Coloured Petri Nets (CPNs) and a ...

Design patterns help to enhance software quality by addressing fundamental challenges in large-scale system development. These challenges include communication of architectural knowledge among developers, accommodating new design paradigms or architectural styles, and avoiding development traps and pitfalls that are usually learned only by experience. This article describes lessons learned from...

Integrated Project funded by the European Community under the " Information Society Technologies " Programme (2002—2006) Executive Summary In this document, we present model transformation techniques used in a methodology for the evolution of software towards new architectural styles. This methodology is being implemented to support the migration to Service-Oriented Architectures but is not res...

Software systems of today are characterized by increasing size, complexity, distribution, heterogeneity, and lifespan. Understanding and supporting the interaction between software requirements and architectures remains one of the challenging problems in software engineering research. To address these challenges we are proposing an integration framework developed within the context of the Tropo...
