Full textThe aim of this thesis is to provide decision support systems to control logistic platforms at the mid-term and short-term levels. Several problems and main notions concerning logistic platform context are described in the first part. In the second part, planning problems are studied. Two linear programming models are proposed to minimize the workforce costs. These models take into account several characteristics : seasonal flow variations, work and flow organization in the platform, and local negotiations of the upstream and downstream flows. In consequence, our decision support system can be used in the flow coordination between supply chain partners. Two types of negotiations are considered : negotiations of upstream and downstream delivered quantities and negotiation of delivery dates. These models have been tested on pertinent randomly generated instances inspired from concerete problems. In the third part of the thesis, the external flows of the platforme are assumed to be fixed. Orders preparation scheduling problem inside the platform is considered. Two families of strong contraints are combined : staircase availability of components (consumable resources) and dixed delivery dates. According to the way the downstream deliveries are organized and penalised, three different cases (based on industrial applications) have been studied. We proposed three branch and bound procedures for these problems, and an integer linear program for the easiest problem. Experimental analysis has been done over heterogeneous randomly generated instance families. In the last part, a series of perspectives for this work are proposed

Full textLes tâches et les contraintes sont représentées à l'aide d'un graphe ET/OU et les durées des tâches sont pondérées par des probabilités d'exécution. Celles-ci expriment une incertitude sur la connaissance exacte des durées d'exécution des tâches qui ne seront réellement connues que lors de l'exécution effective. Ainsi, une tâche s'exécute durant l'une de ses durées d'exécution possibles avec la probabilité associée à celle-ci. Étant donné ce graphe, notre objectif est de déterminer un plan de tâches qui satisfait toutes les contraintes et qui répond aux critères de choix exigés par l'utilisateur en terme de temps, de coût et de probabilité. L'application de ce plan doit garantir le monde de façon que le but soit atteint tout en satisfaisant les contraintes du domaine.
Nous avons appliqué notre méthode de planification à un cas pratique relativement complexe qui concerne la planification d'un ensemble d'agents travaillant ensemble dans un lieu afin d'atteindre un but donné tout en respectant les délais et les contraintes du domaine (temps, coût, probabilité, disponibilité, spécialité,...).

Full textThis PhD thesis consists in the study of two problems in Operational Research. In the first part, a lagrangian lower bound is proposed for a particular employee timetabling problem, followed by a Benders decomposition and a specific cut generation process based on an exponential formulation, that allow the solving of real-size instances. For solving bigger instances, a taboo method is developed. The second part is a study of the Single Machine Earliness- Tardiness Problem with general completion costs and release dates. After computational results obtained by different lower bounds, we give several dominance rules, and provide new elimination rules that turn out to be very efficient. Indeed, we develop an exact method dominating all known approaches for this problem

Full textThe project structure arises in many fields of industry and services. It consists in performing a set of activities that may be linked by precedence relations, and use resources whose capacity is limited. The objective is to minimize a criterion usually linked to the duration or the cost of the project. Most of project scheduling problems in the literature assume that the same time scale should be used to determine activity start and completion dates and check resource constraints at each time. However, although it is often required in practice to build a precise schedule specifying the execution range of each activity, the resource usage can be evaluated on an aggregated basis, like worker shifts. In this thesis, a new model that enables the integration of these two time scales is presented in order to define the periodically aggregated resource-constrained project scheduling problem (PARCPSP). This problem is studied within the framework of complexity theory and several structural properties are established, highlighting major differences with the standard resource-constrained project scheduling problem (RCPSP). These properties allow deriving exact formulations based on integer linear programming, whose linear relaxations are compared. Moreover, several heuristics, such as schedule generations schemes, or an approached method based on a multi time scale iterative process, are proposed. Experimental results show the interest of these different methods and point out the intractability of the problem

Full textWe study in this thesis two approaches that reduce the processing time needed to solve planning and ordering problems in a constraint programming context. We experiment with multiple thousands of processors on the planning and scheduling problem of wood-finish operations. These issues are of a great importance for businesses, because they can better manage their production and save costs related to their operations. The first approach consists in a parallelization of the problem solving algorithm. We propose a new parallelization technique (named PDS) of the search strategies, that reaches four goals: conservation of the nodes visit order in the search tree as defined by the sequential algorithm, balancing of the workload between the processors, robustness against hardware failures, and absence of communication between processors during the treatment. We apply this technique to parallelize the Limited Discrepancy-based (LDS) search strategy to obtain Parallel Limited Discrepancy-Based Search (PLDS). We then show that this technique can be generalized by parallelizing two other search strategies: Depth-Bounded discrepancy Search (DDS) and Depth-First Search (DFS). We obtain, respectively, Parallel Discrepancy-based Search (PDDS) and Parallel Depth-First Search (PDFS). The algorithms obtained this way create an intrinsic workload balance: the imbalance of the workload among the processors is bounded when a branch of the search tree is pruned. By using datasets coming from industrial partners, we are able to improve the best known solutions. With the second approach, we elaborated a method to minimize the changes done to an existing production plan when new information, such as additional orders, are taken into account. Completely re-planning the production activities can lead to a very different production plan which create additional costs and loss of time for businesses. We study the perturbations caused by the re-planification with three distance metrics: Hamming distance, Edit distance, and Damerau-Levenshtein Distance. We propose three mathematical models that allow to minimize these perturbations by including these metrics in the objective function when replanning. We apply this approach to the planning and scheduling problem of wood-finish operations and we demonstrate that this approach outperforms the use of the original model.

Full textIn order to accelerate product flow, reduce inventory levels and make economies in transportation, companies in almost all industries have set up cross-dock centres. These centres are an intermediate point of consolidation in a supply chain. Car manufacturers Renault and Nissan rely on an international network of crossdock platforms to link suppliers of OEM parts with overseas production plants. In a framework of an academic-industrial partnership between the LIMOS laboratory and Renault, this thesis focuses on the activity planning and scheduling at these crossdock centres.Field studies conducted at Renault and Nissan allowed us to identify the characteristics, constraints and cost drivers of crossdock platforms, as well as to target our review of the literature. Based on this, we propose a sequential optimization approach, comprising two integer linear programming models, implemented in CPLEX and tested on industrial data of two Renault platforms. Numerical experiments’ results obtained on the first model (planning) showed a significant improvement in cost, compared to the Renault method. In light of this results, an industrial implementation was made, with such convincing results. The second model (scheduling) proved to be relevant for medium-sized instances. The proposed approach fits to the current configuration of AILN Renault and we consider that it is adaptable to other industries

Full textThis thesis presents three approaches to help companies pla in a dynamic context. Each approach helps at different levels of planning: strategic decisions for long-term, tactics decisions for medium-term, operational decisions for short-term or even at the time of execution. After the generation of a plan, it is possible that the plan becomes unusable following an unforeseen event. The company must then generate another plan based on this new information. It is therefore important for a company to be able to adapt quickly to changes and to be more agile. Companies can use decision support systems to help them make better decisions for their planning. These tools are effective in solving a problem, but are often not adapted to the dynamic context of companies. This thesis presents three approaches to make it possible to adapt the plans quickly following the evolution of the problems. The first approach is for the tactical level of planning. The tactical plan considers a certain planning horizon (ex.: 52 weeks). The solution found for this horizon becomes obsolete after some time, because several elements of the problem have changed. It would be advantageous for a business to always keep the plan up to date whenever there is new information. However, it would take a lot of time. Our approach is to keep the plan up to date, but with the help of decisions made previously. We tested this approach on the problem of optimizing the position of the tools for CNC machines with turrets. We designed an integer program to solve the problem. After finding the optimal tool position for each product to be machined, a new product may be added to the list of products to be machined. There is a great time cost in having to change the position of the tools. We must therefore find the position of the tools for the new product without changing the position of the tools for the other products. The template designed to solve the problem has an objective function that can be reused when adding a new product. It is then possible to see the evolution of the solution when a new product is added. The second approach is for the operational level of planning. The planner can use an optimization program to find a feasible and optimal plan for his/her problem. However, there can be various unforeseen events that make the plan obsolete. For example, a material order may arrive late which creates a delay before being able to manufacture a product. We must therefore find an alternative to the initial plan to overcome this unforeseen event. It can be difficult and even impossible for a human to change the plan while respecting the constraints of the problem as well as the optimality of the plan. The planner may run the optimization program again to take this unforeseen into consideration, but it may take too long. The proposed approach is to use a mixed initiative system making it possible to change a solution returned by an integer program while maintaining the optimality of the solution. The system generates several solutions to be able to quickly return a solution following a modification by the planner. The system is based on a custom technique based on the kernel of the constraint matrix. The third approach is for the strategic level of planning. Decisions at the strategic level are for the long term. For example, a manufacturing company must decide which tools to purchase to improve their productivity. The proposed approach is to suggest choices to the planner when generating plans at the operational level. The business can make choices faster without having to put in a lot of analytical effort. This approach is tested on a scheduling problem located at the operational planning level. This approach uses machine learning to predict the impact on the solution of making certain changes such as purchasing a new resource. The idea is to practice on past problem instances to make suggestions on the current problem instance.

Full textIn this thesis, we study the optimization of flow planning and scheduling, within a strategy to integrate decisions for supply chain planning at tactical level, taking into account operational constraints. The goal of this work is to address the need for consistency between decisions arising from production planning and scheduling. These decisions are often taken in a sequential order, leading most of the time to unfeasible production plans. We propose an integrated approach to solve single-level and multi-level problems in multi-item multi-resource systems configured as job-shops.Both capacitated production planning and scheduling problems, in complex manufacturing systems, are NP-hard. Therefore, integrating constraints of both problems generates a new problem which is even more difficult to solve. We propose a decomposition of the integrated problem into a set of several sub-problems with fixed sequence, solved by Lagrangian Relaxation. The sequence improvement is guided by a Tabu Search. The efficiency of the integrated approach comparing to a standard solver is proved in terms of solution quality and computational effort. In case of multi-level problems, we propose a new mathematical model based on the concept of echelon stock, as well as new algorithms and smoothing strategies to build production plans respecting detailed capacity and bill-of-materials constraints

Full textOur work deals with the problem of production control in large manufacturing firms with a network structure. One of the crucial problems production planners do face is that of insuring good global performance given the number of interactions between different planning and scheduling decisions that take place in a local context. In this work we examine the question of performance and coherence of different production control procedures and we focus on strategies aimed at reducing the length of manufacturing lead-time and increasing due date reliability. This research relies on a specific planning and scheduling approach called the + dynamic anticipation approach ; (daa). This approach consists of a hierarchical two stage decomposition of the planning/scheduling process : the planing stage uses a combined pert/mrp procedure and shop floor control is achieved using a dynamic scheduling rule based on the floats derived at the planing stage. Simulation experiments showed the performance of the daa and it's superiority over other classical production control policies. The high performance of the daa is mostly related to the coherence that it achieves between planing and scheduling decisions. In practical situations however, this coherence is very hard to insure because a lot of unplanned events occur and local actors, faced to short term considerations, always take decisions that may lead to incoherence with global medium term choices. Accelerating or delaying released orders and scheduling the work in process with respect to local performance criteria are the most classical examples of such decisions. So, we pursued the study of the daa taking into account these two situations. On the other hand, we proposed a new evaluation of the performance of different production control approaches that considers economical aspects such as work in process and late penalties costs. These investigations showed the necessity to develop new approaches to control complex production systems and it allowed us to explain the dynamic behavior of production systems

Full textSystems of production represent a privileged area of application of techniques from operational research. Organizing the product flow in such a system is a complex task : the number of constraints to take into account is generally high and the data can be uncertain (it is difficult to know precisely the amount of product that will be sold in several weeks or months). To be able to effectively organize the product flow, the organization is divided into three distinct phases : the strategic phase, the planning phase and operational phase. This thesis focuses on the last two phases for a shampoo production site

Full textIn the first section, we dealt with a state of the art on the single machine problem with heads and tails as well as linked problems. The second section deals with the single machine scheduling problem and the job-shop scheduling problem with unavailability constraints where operations can be resumable or not and unavailability period can be crossable or not. To solve the two problems we present a branch and bound procedure. In the third section we deal with new relaxations for the flow-shop scheduling problem based on positional constraints. We experimentally demonstrate that the principle makes it possible to obtain competitive lower bounds for different problems. Section four deals with a flow-shop problem where operations are submitted to setup time which requires the use of an additional resource. We present theoretical results and algorithms to solve a two-machine problem. Finally, in the last section, we present our work on the software Direct Planning distributed by the company Volume Software

Full textWith the economic and technologie evolution in resent years, a new production type has been developed in the well industrialized countries. Named as complex production, it can be characterized by the following facts: - long and uncertain production cycles - very complex product nomenclature containing some thousands components - small lot size of production these characteristics of the complex production add new constraints to the production management, and make it altmost impossible to master the manufacturing cycle and to control working process and final product stocks with a existed method. They make it also necessary to search new and to redefine old planning methods. In this study, we try to analysis, by a computer simulation method, the typical problems one can meet in a production system in the complex production industries. We will see how the product complexity may have a impact on the production organization, how it is important for this production type to articulate the planning and scheduling for a good mastering of stock levels and manufacturing cycles, and how the performances of priority rules in the workshop depend on the planning methods

Full textThis thesis is within the framework of mid-term production planning in a make-to-order production environment and more particularly on scheduling problems. It proposes a two-level decisional approach allowing the load-capacity adjustment of resources and the scheduling of the operations belonging to a whole of Production Orders (PO). The higher level (macro-scheduling) positions PO on a mid-term horizon discretized in periods and aids the decision maker to elaborate an optimized aggregate planning taking into account the selected management policy (overtime, subcontracting, delays, etc). This level is modelled by a linear program in mixed variables. Aggregation mechanisms are proposed. They allow associate at the higher aggregate level data (associated with macro periods) obtained from detailed data (defined over continuous time). The study is also interested on the extensions of the macro-scheduling model in the case of the taking into account of various types of decisional levers, of the taking into account of alternative resources, etc. The lower level (scheduling) finely positions (in continuous time, short-term horizon) the operations on resources. It is charged “to follow” the macro-scheduling having optimized the positioning of PO. In order to integrate the two decisional levels, different mechanisms of “guidance” are proposed. These mechanisms make it possible to disaggregate the decisions taken at the higher level. These mechanisms accept the use of standard scheduling software at the lower level. Numerical experiments are carried out in order to study the performances of the multilevel structure. These experiments allow appreciate the behaviour of the decisional structure face to different sizes of characteristic elements of the approach: discretization length, guidance mechanisms, constraints rate

Full textThis thesis deals with scheduling problems in manufacturing cells. It aims at studying different classical models, analyzing links and differences between those models and the practical associated problems. The approach is to analyze the problems of our indus trial partners, to study the complexity of the problems or the structure of their solution, and to propose exact or approached solution methods. The first axis of this thesis is the study of scheduling problems with inlout resource constraints. The problems considered are robotic flowshops and the new concept of operator non-availability. The second axis concerns scheduling problems with high multiplicity, where parts are aggregated into categories. Complete description of a schedule (i. E. The starting times of the operations) is then only pseudo-polynomial of the size of the input

Full textThe aim of this work is to measure the performance of a production control system. We focus on the problematic of control system in an environment composed of several decision centers, taking into account reaction delays. When an unexpected event is detected by a decision center, some modifications of the schedule required by this decision center may induce consequences on tasks under the control of other decision centers, because there exist some constraints between the jobs controlled by different decision centers. Each modification during the execution of a task should be submitted to the approval of each concerned decision center. The coordination between these decision centers implies a reaction delay between all of them. But, the suggested modifications may not be compatible with these reaction delays. This is why we present a control model for reactive scheduling, including reaction delays between decision centers. This model leads to a formal definition of reactivity being used to the industrial case of the high-speed train (TGV) maintenance at the French railway company (SNCF)

We develop a multi-agent methodology for distributed dynamic scheduling of tasks that are subject to temporal and resource constraints, based on a dynamic priority determination. Confidentiality is respected by limiting information exchange to probabilistic values. The proposed architecture relies on mobile agents for task execution and reactive resource management, where perturbations are absorbed implicitly. We define a negotiation protocol between agents and two heuristics for task assignment and scheduling

Full textThis thesis focuses on the trains platforming problem within busy and complex railway stations and aims to develop a computerized dispatching support tool for railway station dispatchers to generate a full-day conflict-free timetable. The management of rail traffic in stations requires careful scheduling to fit to the existing infrastructure, while avoiding conflicts between large numbers of trains and satisfying safety or business policy and objectives. Based on operations research techniques and professional railway expertise, we design a generalized mathematical model to formalize the trains platforming problem including topology of railway station, trains' activities, dispatching constraints and objectives. As a large-scale problem, full-day platforming problem is decomposed into tractable sub-problems in time order by cumulative sliding window algorithm. Each sub-problem is solved by branch-and-bound algorithm implemented in CPLEX. To accelerate calculation process of sub-problems, tri-level optimization model is designed to provide a local optimal solution in a rather short time. This local optimum is provided to branch-and bound algorithm as an initial solution.This system is able to verify the feasibility of tentative timetable given to railway station. Trains with unsolvable conflicts will return to their original activity managers with suggestions for the modification of arrival and departure times. Time deviations of commercial trains' activities are minimized to reduce the delay propagation within the whole railway networks

Full textMulti-cluster tool is a highly automated and costly wafer fabrication system with multi-loop coupling structure, and scheduling of such equipment directly affects the overall efficiency of semiconductor manufacturing enterprises. Multi-cluster tools scheduling problem has the features of large scale, complex wafer flow patterns, strict residency time constraints and intense resource conflict, which are significantly different from any other manufacturing system. Since the existing literatures have proved that most of the wafer fabrication systems scheduling problems are NP-hard, it’s difficult to obtain the optimal solution by using exact algorithms. Thus, how to develop an efficient heuristic algorithm to solve the multi-cluster tools scheduling problem attracts considerable attention both in academia and in industry. After reviewing the literatures, it is found that the research on the cyclic scheduling problem of multi-cluster tools rarely takes into account the characteristics of residency constraints. The scale of the object is limited to three single cluster tools, and the proposed scheduling methods are mostly mathematical programming and simple scheduling rules. Therefore, in this thesis, the multi-cluster tool is studied and our research mainly focuses on the characteristics of residency constraints, resource constraints and wafer flow patterns. Based on the descriptions of research domains, some solid models are developed for different scheduling problems and some efficient heuristic algorithms are constructed to realize the objectives. To deal with the problem, different approaches are proposed: A non-linear mixed-integer programming model, a two-stage = approximate-optimal scheduling algorithm, and a chaos-based particle swarm optimization-tabu search hybrid heuristic algorithm. Simulation experiments and analysis demonstrate the effectiveness of these algorithms. Results show the stability and efficiency of proposed algorithms

Full textThe overall goal of the production planning is to come up with most economical plan for minimizing slacks in terms of work force, equipment and work in process. A primary goal in planning is to provide an effective coverage to demands over an intermediate time horizon. The procedure computes time windows during which jobs have to be processed, a time margin is allowed for take into account the unexpected. In a first part, we suggest a lead time reduction, what implies that the production planning receives input from shop floor control so as to correct the time margin. Detailed scheduling of the various element of a production system is important in order to do some form of optimization at a higher level. Financial target is an essential point since inventory and work in process involve significant investments. Theorical scheduling models usually assume that there are n jobs to be scheduled and after scheduling these n jobs the problem is solved. In real life, every day (week or month) new jobs are added. The dynamic nature of this problem needs a rescheduling process. In the second part of this work, we propose a data-driven simulation procedure taking into account the financial targets. In addition, the different rules that have been taken to handle various aspects (conflicts, preemption. . . ) are summarized

The objective is to propose some tools allowing the autonomous and cooperative navigation of AGV fleets in manufacturing systems for which temporal constraints are important. After presenting the state of the art of each field (manufacturing systems and agent navigation), the impacts of the cross-fertilization between these two fields are presented. Then, two issues, related to the navigation of mobile agents in manufacturing systems, are studied. The first issue focuses on decentralized motion planning where a scheduling function is combined with the planner for each agent. This function allows choosing a resource during the navigation to complete the ongoing operation of the transported product at the soonest date. The first proposed approach consists in a heterarchical architecture where the AGVs have to plan (or update) their trajectory, schedule their product and solve their own conflict with communicating agents. For the second approach, hybrid architecture with a supervisor, which assists agents during the navigation, is proposed. The motion planning scheme is divided into two steps. The first step uses global information provided by the supervisor to anticipate the future collisions. The second step is local and uses information from communicating agents to ensure the collision avoidance. In order to reduce the computational times, a particle swarm optimization is introduced. The second issue is focused on the cooperative control, allowing a rendezvous of nonholomic agents at a specific configuration. This rendezvous must be achieved in a prescribed time, provided by the higher level of control. To solve this rendezvous, a fixed time (i.e. independent of initial conditions) switching control law is proposed, allowing the convergence of agent states towards a resource configuration. Some numerical and experimental results are provided to show the feasibility of the proposed methods

Full textIn the first part of this work, we are interested in the problem of optimal control production in a medium term supply chain of two stages. The objective is to understand, what is the gain of global optimisation in contrast to local. We evaluate the behaviour of our system within two different types of demand. The models are formulated using tools from mathematical programming and from queuing theory. Many analyses are carried out, in order to define the behaviour of each model. These analyses enable a comparison between the models and help us identify the true superiority of global optimisation. In the second part, we examine the problem production scheduling, which is applied in the petrochemical industry. We study the problem of scheduling the loading and unloading of tanks and the scheduling of crude oil to the refinery. The objective here is to minimise the set up cost of the tanks. We propose a general model, which takes into consideration all the different types of blending preparation and the different options of distillation of the crude oil. We give the different methods we have developed in order to improve the performance of our models. We present a series of valid inequalities for the scheduling of crude oil, a new process of multi-generation of cuts in Benders' decomposition algorithm and a general comparison among all the methods studied. Keywords: Optimal control, planning, flow control, global vs local optimisation, scheduling of crude oil, mathematical programming, queuing theory, Benders decomposition

Full textIn this work, we propose an approach for the modelling of the flexible allocation of human resources as far as planning of industrial activities is concerned. This model takes into account two aspects of flexibility, related one to the modulation of the working time, and the other with the variety of tasks which can be achieved by a given resource (multi skills). We propose two methodological approaches for the resolution of the model: a first approach is based on mono-criterion genetic algorithms which make a systematic research concerning the possible choices of the operators allocation, a second approach based on the assignment from rules of priority with simultaneously takes into account of the criticality of competences and efficiency of the resources in order to assign the most suitable operators. The issue of this work relates to the resolution of a complex problem with an acceptable search time

Full textIf the litterature of decision-making has addressed a variety of problems, the ability to make an agent autonomous in the choice of its goals remains a difficult issue to address. This capacity is nevertheless essential for an agent in order to be automous in its environment. This thesis aims at allowing a robot to plan its own actions for multiple concurrent objectives, in a probabilistic environment and with resources. The first contribution of this work is the proposal of a new model for the objectives, the motivations, constituted from an automaton. Motivations describe the evolution of each objective using states and transitions corresponding to the realisation of tasks, and define the reward gains. The second contribution concerns a planning method that makes use the motivations. This method is hierarchical and proposes at first to solve the realisation of the tasks that are relevant for the motivations. By exploiting the specific context of each task, we can quickly compute their policy and calculate their execution model, which we call macro-action. We then use these macro-actions in a high-level local planning process, allowing us to return a conditional plan of the macro-actions to be executed, which we call macro-actions agenda. To solve a problem over time, we propose to include this planning system in a deliberative architecture that will control the execution of the agenda and produce new ones
