Service-Oriented Architectures (SOA) are broadly used by companies to gain in flexibility. Web service is the fitted technical solution used to support SOA by providing interoperability and loose coupling. First research works allowed us developing genuine middleware based on a new paradigm called aspect based services to dynamically adapt services orchestration. This approach can also be used for SPARQL (Protocol and RDF Query Language) requests to dynamically access Web services ontologies. According to these pre requisites, this paper presents our approach, current and future research works. Source

Abstract In a previous work (Bouyahia et al., 2010), we introduced and studied the probabilistic generalization of the classical total weighted completion time problem. We defined two a priori strategies devoted to the incorporated problem on parallel identical machines (UA and UB). The main drawback of the proposed a priori strategies is that the machine loads are not balanced after deleting the absent jobs from an a priori schedule. In this paper, we try to overcome this limitation by proposing an a priori strategy denoted as Uk which takes into account the load balance. First, we present the algorithm of the load balancing strategy and we explicit the objective function. Then, we study its complexity and its performance compared to the other strategies. Special care is also devoted to assess experimentally the performance of Uk. © 2012 Elsevier Ltd. All rights reserved. Source

The work presented in this paper is related to knowledge management during the design process of mechanical products. More exactly, we are concentrating on the knowledge reuse process. We propose a knowledge reuse system (KRS) based on two approaches. Namely, an organizational approach and a modeling user approach. Both are ontology-based models. Our system takes into account, the actors' roles (by the organizational approach), their preferences (by the model user approach), and their collaboration throughout the product design process in order to help designers to get knowledge that is considered the most relevant in all the phases of the product design process. © 2014 The Authors. © 2014 Published by Elsevier B.V.
