Cherif, Ghassen. "Ordonnancement dans les ateliers hybrides en environnement incertain." Thesis, Normandie, 2021. http://www.theses.fr/2021NORMLH04.
Full textThis thesis concerns the scheduling problems for a class of flexible manufacturing systems (FMS) in uncertain environment. The considered systems meet the requirements of Industry 4.0, which require more flexibility and modularity to offer personalized products. More precisely, the proposed systems in this work are called hybrid FMS and deal with operations with partial precedence constraints. The first contribution is a systematic approach used for the modeling of hybrid FMS with timed Petri nets (T-TPN) and a multi-level formalism based on the hierarchical organization of operations. The second contribution concerns the scheduling of hybrid FMS. We use the beam search and propose a cost function based on the multi-level modeling. We also offer a new variant of beam search called Generation Filtered Beam Search (GFBS). This new variant improves the quality of the selected candidates compared to other variants of beam search by a better balance between the width and the depth of the search. The third contribution concerns the study of interruptions that can affect the system. A risk of interruption, due to the occurrence of uncontrollable events, is integrated, and a new cost function that incorporates this risk is defined. Finally, a modified beam search algorithm, called Generation Double Filtered Beam Search (GDFBS), which accelerates the convergence of the method, is proposed. The new algorithm is based on a filtering mechanism that uses the cost function to selectively explore the state space of the TPN in order to find a control sequence that achieves a tradeoff between performance and risk

Full textIn this thesis we discuss the performance of flexible manufacturing systems subject to failures. We describe two models of manufacturing systems with n stations, and with a limited conveyor belt moving at constant speed and with unlimited queue size. The conveyor belt is composed of two parts. The first part is between entry point and the exit point of the system; and the second is between exit point and entry point of the system. In the first model the pieces may leave the system with a given probability and they may request service from the same station several times. In the second model the pieces are tested before going to the second part of the conveyor and they may request only once service from any station. Each model has being studied with two differents approaches: an analytical model based on queueing theory and a simulation model using the QNAP2 package

Full textThe flexible manufacturing system is a production concept indispensable for the enterprise which wants to stay competitive. A Flexible Manufacturing System consists of three sub-systems : physical system, information system and pilot system. It's conception is complex. First, we have surveyed the existing methods and tools used in the different phases of it s elaboration from the different view points. We have chosen the method MERISE as a conception tool because it is adequate for the problems of Flexible Manufacturing System. In the second time, we have centred our research on the evaluation of parameters of the physical system of the workshop. It' s product capacity, in term of quantity , quality and rapidity of product elaboration, depends on these parameters. Modelling and Simulation seem to be indispensable and comp elementary to solve the problem and to answer the complex problem given by the impact of the variation of the different parameters. On the other side, they permit to define the required specification elements for the choices of machines. We propose also a structured process for the best use of simulation and evaluation of parameters in order to obtain a correct and optimal solution according to some criteria. It brings a considerable contribution in conception of Flexible Manufacturing System

Full textLn this thesis we consider the performance evaluation of flexible manufacturing systems. We study a flexible manufacturing system with three servers within a station. We model the behavior of this system with limited or unlimited capacity queues. Based on queueing theory an analytic model is found and is validated by simulations. Finally, we use the same approach to cope with the problem of a flexible manufacturing system with N stations in tandem with limited or unlimited capacity

Full textIn order to lower the « time to market » delays, modem factories have to increase flexibility and reactivity in their production system. In an FMS, this can be achieved thanks to a full decentralization of the decision process over the resources. Thanks to such an organization, perturbations are not able to spread from a small group of resources to the entire workshop. On another hand, it implies that each resource is able to perform autonomously its different tasks. W e have built a new controller architecture that remains both on reactive control (for autonomy and reactivity) and on neural networks (to enable the controller to adapt to new environments). Since neural networks are monolithic structures, they cannot fit with the intrinsic modularity of reactive architectures. So we have defined a specific « neuro-reactive » controller. It is a modular network based on a new update mode : the scheduled mode. This mode enables the network to build activation path from the input sensory data to the output motor neurons. The multiple crossing nodes between the different activation paths create, during the learning process, some functional neural groups comparable to the biological neural assemblies. Different testing environments have been used, showing that the network is able to learn « by parts » a complex task thanks to a semi-distributed localization of information

Full textA manufacturing system may be represented by Discrete Event System (DES). Apart from planning (where people work with ratios of products fabricated per week or per day), any modelling could be based on the concepts of event and activities. An event corresponds to a state change. An activity is a black-box summarizing what is occurring between two events. When using Petri Nets, events are associated with transitions, and activities with places. Our work proposes a supervisory synthesis for Discrete Event System modelled by a class of Petri Net called Marked Graph. The objective of this synthesis is to build a control law that enforces the system to respect a set of given specifications. To model these specifications, we propose new mathematical formulas called Marking Exclusion Constraint (MEC). This model is our first contribution. The Second main contribution of my thesis is to synthesize a computationally efficient technique to build a supervisor that enforces the system to respect the constraints by avoiding a set of forbidden states modelled by MEC specifications. We extend this synthesis technique to solve the problem in the presence of uncontrollable events and unobservable events. Sometimes in order to study the performance aspects, we must take in consideration the time data. Thus we address control synthesis for Timed Discrete Event Systems under MEC specifications by using Timed Petri Nets

Full textThis work is a contribution to the elaboration of an information system for a PMS. It deals with the construction of a technical data base and with a scheduling method that minimizes the number of set-up operations. Pour main parts can be distinguished. - In the first part, the PMS studied is described. - The second is a review of the different methods used to construct a production manufacturing system (the ones based on the physical system and the ones based on the information system ). The choice of MERISE method is justified - In a third part, some conceptual models are presented (describing routings, tools, fixtures, DNC programmes, etc. . . ). - At last a scheduling method that minimizes set-up times is proposed. This method uses mathematical tools, such as Galois lattice, interval graphs. A prototype of this method gives very good results in numerous examples: about 50 % of set-up operations can be avoided in all cases studied
