چکیده

Ax approach for designing and developing decision aiding systems is presented through the design and definition of the architecture of a system, corresponding to a real problem: that of providing aid to designers The purpose of the decision aid is to provide assistance to computer system designers tackling interface usability problems and needing to know which modelling techniques out of an array would be more appropriate to apply. Different aspects of the design problem may call for different modelling techniques to be recruited. The design of the DDAS accommodates that reality. The architecture of DDAS is based on principles of systems thinking, in particular soft systems methodology, for eliciting and structuring knowledge relevant to a generic design space, and on fuzzy sets through test score semantics for representing and evaluating the meaning of relationships between components of the design problem and the modelling techniques. The advantage of this architecture is that it could be used for other problems -where the decision maker, who is not necessarily an expert, wants to know what tools and techniques are appropriate for him and his particular problem ABSTRA1T. Cet article présente une méthodologie pour dessiner l'architecture et la réalisation d’un système interactif d'aide a la décision destine a être utilise par concepteursréalisateurs (DDAS) Le but de ce système est d'aider les équipes de concepteurs-réalisateurs qui heurtent a des problèmes d’ utilisabilite, et veulent savoir quel modèle d'un ensemble peu: leur servir I1 n 'est pas exclus que certains aspects du problème en son totalité peut faire appel a de différents modèles. Le système DDAS, tel qu'il est conçu, peut répondre a cet besoin. L'architecture du DDAS repose sur des principes de la philosophie des systèmes (Systems Thinking) en particulière des systèmes souples (Soft Systems Methodology) qui lui sen de base pour 1' élicitation et représentation de connaissances qui ont pour référent une espace générique conception-réalisation En plus, le système DDAS utilise des conceptes tirées des ensembles flous, a savoir. lest score semantics, pour représenter et évaluer le sens des relations entre les constituents du problème et les techniques de modélisation. Une des bénéfices de cet architecture c'est qu'il peut être utilise dans d'autres situations ou le décision repose sur le choix entre un nombre de techniques ou d'autres outils et utilisateur. qui n 'est pas forcement expert dans ces techniques, veut savoir ou et quand Us conviennent a aider son problème

A Slicing Approach for Parallel Component Adaptation

Software reuse has received considerable attention as a technique for aiding software designers. One mechanism for increasing the efficiency of reuse is component adaptation, particularly when designing large and intricate systems. Component adaptation composes reusable components in an architecture to produce a new system. Specification slicing is a method for decomposing complicated systems i...

Chapter 1 ARGUMENTATION THEORY AND DECISION AIDING

The purpose of this chapter is to examine the existent and potential contribution of argumentation theory to decision-aiding, more specifically to multi-criteria decision-aiding. On the one hand, Decision aiding provides a general framework that can be adapted to different contexts of decision-making and a formal theory about preferences. On the other hand Argumentation theory is growing field ...

Reusing Software Design : A Generic Architecture-based Approach

We are attempting to build a framework and computational environment to assist software designers in designing software systems eeciently and reliably. Our approach is based on abstracting the design as well as the process involved in designing a software system and reusing them to design new systems. The emphasis is on building an environment in which the system acts as an assistant that deliv...

From decision theory to decision aiding methodology

The paper presents the author’s partial and personal historical reconstruction of how decision theory evolved to decision aiding methodology. The presentation shows mainly how “alternative” approaches to classic decision theory evolved. In the paper is claimed that all such decision “theories” share a common methodological feature which is the use of formal and abstract languages as well as of ...
