Full textThis thesis considers a complex workshop scheduling problem, which is rarely studied to our knowledge. This workshop has a hybrid composition : one or several machines are available at each stage. Main considered constraints are batch processing and total tardiness minimization. Solution methods are embedded on the information system of research program of Soufflet Group. Given the complex structure of the workshop, it has been split in order to study the parallel machines scheduling problem individually. Different solution methods are developed. Obtained results are used to build a classification of instances and solution methods. To solve described problems, exact and approach solution methods are proposed. We have adapted iterated search, tabu search, genetic algorithms, … Findings from solving parallel machines scheduling problem are employed to develop a two levels solution method for the described flow shop problem. Results show the performance of developed algorithms to find good quality solutions for described scheduling problem. Similarly, industrial problems are considered, in order to optimize operational behavior of research center

Full textThis thesis deals with the multi-objective Resource Constraint Project Scheduling Problem (RCPSP). After a specific literature review, we solve the problem with exact approaches in the first place: the Two Phases Method and the Parallel Partitioning Method. Due to the NP-hardness of the problem, the exact methods are only able to solve small instances. For this reason, we apply the approximated methods to deal with larger problems. The genetic algorithms are firstly adopted to solve large-scaled instances. Moreover, we propose to improve the basic scheme with several hybridizations. A local search with Mapping Method is applied for a better exploration of the solution space. Next, we consider a special case where the decision-makers wish to reduce the number of solutions. Thus, in this part of the thesis, we try to select the most interesting solutions among the whole non-dominated front. For this purpose, several dominance relationships are considered as alternatives of the Pareto dominance. These dominance rules are implemented in the basic genetic algorithm schemes, as well as those with local search. The results show that the considered hybridizations enhance highly the basic method results. Our future research will highlight more complex multi-objective RCPSP problems and the industrial application

Full textThe work presented in this PhD thesis deals with optimization problems in the context of internal warehouse logistics. The field is subject to strong competition and extensive growth, driven by the growing needs of the market and favored by automation. SAVOYE builds warehouse storage handling equipment and offers its own GTP (Goods-To-Person) solution for order picking. The solution uses an Automated Storage and Retrieval System (ASRS) called X-Picking Tray System (X-PTS) and automatically routes loads to workstations via carousels to perform sequenced operations. It is a highly complex system of systems with many applications for operational research techniques. All this defines the applicative and theoretical scope of the work carried out in this thesis. In this thesis, we have first dealt with a specific scheduling Job Shop problem with precedence constraints. The particular context of this problem allowed us to solve it in polynomial time with exact algorithms. These algorithms made it possible to calculate the injection schedule of the loads coming from the different storage output streams to aggregate on a carousel in a given order. Thus, the inter-aisle management of the X-PTS storage was improved and the throughput of the load flow was maximized, from the storage to a station. In the sequel of this work, the radix sort LSD (Least Significant Digit) algorithm was studied and a dedicated online sorting algorithm was developed. The second one is used to drive autonomous sorting systems called Buffers Sequencers (BS), which are placed upstream of each workstation in the GTP solution. Finally, a sequencing problem was considered, consisting of finding a linear extension of a partial order minimizing a distance with a given order. An integer linear programming approach, different variants of dynamic programming and greedy algorithms were proposed to solve it. An efficient heuristic was developed based on iterative calls of dynamic programming routines, allowing to reach a solution close or equal to the optimum in a very short time. The application of this problem to the unordered output streams of X-PTS storage allows pre-sorting at the carousel level. The various solutions developed have been validated by simulation and some have been patented and/or already implemented in warehouses
