Résumé

In this paper, we introduce a framework for knowledge reuse and deduction in mechanical
products design and development. The proposed system e®ectively exploits the capitalized and
inferred knowledge. To this end, we settled up an ontology dealing with the design process of
mechanical products such as \the car". The ontology-based framework is supported by a
software tool that brings an automatic and personalized assistance to correspondent actors
using the deduction process. Indeed, the systems provides the relevant knowledge to the suitable
users in order to facilitate their professional tasks considering their roles and collaboration.
Experimental results have demonstrated the e®ectiveness of reusing knowledge during product
development lifecycle.

Résumé

In this paper, we would like to assess the positive impact of the recommendation process during the professional activities of business actors. We are interested specifically in the improvement of the economic life of the handicraft women from emerging countries. To this end, we introduce a utility based recommender dealing with the procurement opportunities. Actually, we proposed a utility function which takes into account the weighted preferences and expectations of final users. The system is evaluated based on the gain to obtain if the proposed recommendations are adopted in addition to the satisfaction level of the final users.

Résumé

Recommending personalized events from the huge amount of information on the social web is a challenging problem. Besides, dealing with such recommendation improves significantly the professional communities activities. Likewise, it helps them to make appropriate decisions while saving time and efforts. In this paper, we propose a hybrid recommender system which suggests suitable events to the HanDicraft Women (HDWs) from Tunisia and Algeria. The established system considers the final user needs and demographic attributes. Indeed, it combines the knowledge-based and demographic approaches together. Useful information related to the HDWs and available events are represented through a semantic formalization : Friend Of A Friend (FOAF) Ontoloy and Online presence Ontology (OPO). Moreover, the recommender is able to manage the dynamicity and heterogeneity of the HDWs environments since it is based on a multi-agent architecture.

Résumé

The online supply requirement management within a heterogonous environment represents a real challenge. While the traditional e-purchase is widely adopted, the e-barter seems to be an ambitious alternative. It is mainly solicited when suppliers might be unavailable or the delivery timeouts are important. Moreover, it reinforces the communication between the producer and his professional network. In this paper, we propose an emulation of the handicraft women e-procurement process based on the power of multi-agent paradigm and ontology formalism. Indeed, we establish an e-barter framework which targets to recommend in real time, under different circumstances and regarding the handicraft woman situation the suitable exchange partners. Likewise, we established several producing rules in order to deduce automatically the best sourcing moment. Furthermore, the handicraft woman which is the decision maker might drive an e-barter auction (e-BA) process in order to choose the best exchange opportunities and then minimize her expenses. We consider the e-BA as a new concept merging the barter and auction notions.

Résumé

Suitable suppliers’ recommendation forms the basis for a successful procurement process. An automated personalization of procurement opportunities relies on the buyer and the seller profiles consistency. However, dealing with their profiles matching is not a trivial task. In fact, each contextual detail may play a crucial role in the decision making procedure especially when final users express very specific and variable needs in a heterogeneous and inconstant environment. In this paper, we designed and developed a multi agent system (MAS) for the supply chain automatization. It includes two supplier selection levels followed by a negotiation module relying on the handicraft woman online situation. Several handicraft business ontologies in addition to multi-side profile ontology are developed in order to drive the agent communication with the internal and external environment.

Résumé

En vue de s’approvisionner, les femmes artisanes brodeuses font face à divers problèmes. Disposer d’une vue globale portant sur les fournisseurs adaptés, les meilleures opportunités d’approvisionnement, ainsi que la gestion de rupture des stocks représentent un réel défit pour elles. Face à ces problèmes, les systèmes de recommandation ont montré leur performance en matière de personnalisation des connaissances accordées aux professionnels. Dans ce sens, nous proposons un prototype d’un système suggérant les fournisseurs de confiance les mieux adaptés par rapport au profil de la femme artisane en s’appuyant sur trois niveaux de sélection, suivis d’une phase de négociation. Le prototype proposé se base sur une architecture multi-agents et se sert d’une ontologie métier modélisant le métier de la broderie ainsi qu’une ontologie de profil permettant de définir les profils des acteurs métier.

In order to procure, the handicraft women (embroideresses), face various issues. Having a global overview on the suitable suppliers, the best procurement opportunities and the inventory shortage management represent a real challenge for them. To deal with these issues, the recommender systems have shown their performance in terms of the personalization of the knowledge provided to the professionals. In this respect, we propose a prototype for a system suggesting the trustworthy and suitable suppliers according to the handicraft woman profile and relying on three selection levels, followed by a negotiation phase. The proposed prototype is based on a multi-agents architecture and uses a business ontology modeling the embroidery business as well as profile ontology for setting the business actors’ profiles.
