A real time solution to control disassembly processes.

International audienceDisassembly of manufactured products induces both disassembly costs and revenues from the parts saved by the process. At the planning stage a good trade-off has to be found between the costs of disassembly and the final profit. At the control stage it is important to assure an optimal balance of the line as well as the complete disassembly processing during the rest of the working time. A real time control method based on modeling of disassembly by the precedence graph and on a stochastic algorithm is presented in this article

Applying equal piles approach to disassembly line balancing problem.

International audienceDisassembly process decomposes a product into parts or subassemblies. Due to the uncertainties that occur during this process, designing and balancing a disassembly line is a very challenging problem. To deal with the disassembly line balancing problem a new method which relies on the equal piles approach is proposed

Disassembly line scheduling with genetic algorithms.

International audienceDisassembly is part of the demanufacturing and it is meant to obtain components and materials from end-of-line products. An essential performance objective of a disassembly process is the benefits it brings, that is the revenue brought by the retrieved parts and material, diminished by the cost of their retrieval operations. A decision must be taken to balance an automatic disassembly line. A well balanced line will decrease the cost of disassembly operations. An evolutionary (genetic) algorithm is used to deal with the multi-criteria optimization problem of the disassembly scheduling

Contribution à l'étude de la conduite des systèmes de désassemblage.

The interest on the disassembly process is directly linked on the product recycling and recovering at the end of its life. Most of the researches in the disassembly field are concetrated on the level of process planning and disassembly sequencing. The lack of studies in the field of control of the disassembly process made us to propose a new solution regarding the process optimisation using an original approach. The definition of the real time sequencing of the disassembly process ensures the realism of the problem and gives an original feature to our work. An architecture for controling the disassembly process is proposed. Interfaces are entirely conceived under Visula C++ and they integrate modules of decision support.L'intérêt porté au désassemblage est lié aux notions de recyclage et de récupération des composants et de la matière des produits manufacturés en fin de vie. La plupart des recherches dans le domaine du désassemblage sont concentrées sur la planification du processus et sur la représentation des gammes de désassemblage. Face au manque de travaux en commande en temps réel des systèmes de désassemblage nous avons proposé une solution visant l'optimisation du processus de désassemblage par une nouvelle approche de conduite des systèmes de désassemblage. La définition des équations de l'ordonnancement du désassemblage en temps réel garantie le réalisme du problème et nous assure l'originalité de l'approche. Une architecture de système de commande est proposée. Les interfaces de commande sont conçues sous l'environnement Visual C++ 6.0. Elles intègrent une analyse de l'équilibrage de la ligne et un module d'aide à la décision
