Abstract:

Dans le marché d’aujourd’hui, l’un des facteurs de survie les plus importants pour une entreprise est la garantie de la satisfaction des clients. Parfois, une entreprise ne peut pas satisfaire les exigences de ses clients à cause de contraintes telles que la capacité limitée ou les dates de fin strictes. Elle est donc obligée d’ignorer certaines commandes et de les rejeter ou encore de sous-traiter ces commandes. Dans les deux cas, la société est soumise à des frais. Dans cette thèse, nous étudions les différents types de ligne de production dans lesquels le rejet des commandes est possible. D’abord, nous avons étudié le problème d’ordonnancement bi-objectif sur une seule machine. Nous avons proposé une méthode exacte et plusieurs méta-heuristiques et heuristique efficaces pour trouver une bonne estimation de solutions non-dominées. Ainsi, nous avons étudié les différents concepts de dominance afin de limiter notre recherche dans la région la plus prometteuse du front de Pareto. Par la suite, nous avons étudié un problème d’ordonnancement réentrant à deux machines. Dans ce cas, le rejet des tâches a lieu en fonction de leurs dates de fin strictes. Nous avons considéré deux décisions simultanées : l’acceptation des tâches et leur ordonnancement. Un modèle de programmation linéaire mixte en nombres entiers et différents algorithmes génétiques multi-objectifs, ainsi que l’intégration des concepts de dominance divers, ont été proposés. Enfin, un problème plus général d’ordonnancement flow-shop de permutation réentrant avec dates de fin strictes et le rejet autorisé a été abordé
In today’s competitive market, one of the most important survival factors for a company is the achievement of customers’ satisfaction. Sometimes, a company can not fulfill its customers’ requirements due to the constraints such as limited capacity or tight due dates so it is obliged to ignore some orders and reject them or find another supplier to out-source those orders. In both cases, the company is charged a fee. In this thesis we investigate different types of production line in which rejection of the jobs is possible. At the beginning, we studied a variant of the problem as bi-objective single-machine scheduling problem with rejection. We proposed an exact method and some efficient metaheuristics and a heuristic to find a good estimation of non-dominated solution set. We found that in industrial case, most of the time the decision maker preferred the non-dominated solutions placed in the middle part of Pareto front. So we investigated different dominance concepts apart from Pareto in order to limit our research into the most promising region of Pareto front. Then we studied a two-machine re-entrant scheduling problem with rejection. In this case, the rejection of jobs occurred due to their strict due dates. So we examined simultaneous job acceptance and scheduling decisions. A mixed integer linear programming model and different multi-objective genetic-based algorithms were proposed by integrating various dominance concepts. Finally, a more general problem of re-entrant permutation flow-shop scheduling problem with strict due dates and rejection was tackled

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO
COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
PROGRAMA DE SUPORTE À PÓS-GRADUAÇÃO DE INSTS. DE ENSINO
Nas organizações industriais contemporâneas, a competição global e o avanço das tecnologias de informação tornam os produtos e processos cada vez mais semelhantes. O desempenho operacional passa, então, a ser um dos principais mecanismos de diferenciação. Nesse cenário, a área de planejamento e programação da produção ganha um inédito papel estratégico. O presente estudo se propôs a investigar esse novo papel com um olhar centrado nas rotinas organizacionais e nas pessoas que exercem a função. Mais especificamente, a partir de uma abordagem qualitativa e interpretativa, o trabalho utilizou o método fenomenográfico para compreender como os programadores concebem a competência nas suas rotinas organizacionais. A análise das entrevistas identificou três diferentes concepções. A primeira está associada à tarefa de alocação eficiente de recursos e materiais. A segunda vê a programação como um processo de mediação entre as diferentes áreas da empresa. E a terceira atribui ao programador de produção a reponsabilidade de fazer a gestão estratégica da operação. Além disso, foram identificadas seis dimensões do fenômeno que explicam e diferenciam as concepções, são elas: Raciocínio lógico, Conhecimento técnico (do processo produtivo), Conhecimento sistêmico (de outras áreas), Estratégia de negociação, Aspecto manifesto da rotina e Envolvimento com a estratégia corporativa. Os achados sugerem, por fim, que a dimensão estratégica da programação é verificável, em diferentes graus, nas suas rotinas. Além disso, ao revelar a concepção competência como sendo a mediação entre as diferentes áreas da empresa, o estudo traz as estratégias de negociação para o centro do debate sobre a realização competente das rotinas de programação da produção.
In contemporary industrial organizations, global competition and the advancement of information technologies make products and processes increasingly similar. Operational performance then becomes one of the main differentiation mechanisms. In this scenario, the area of production planning and scheduling gains an unprecedented strategic role. The present study aimed to investigate this new role with a focus on the organizational routines and the people who perform them. More specifically, from a qualitative and interpretative approach, this study used phenomenography method to understand how schedulers conceive competence in their organizational routines. The analysis of the interviews identified three different conceptions. The first is associated with the task of efficient allocation of resources and materials. The second sees scheduling as a process of mediation between the different areas of the company. And the third assigns to the production planner the responsibility to do the strategic management of the enterprise operations. In addition, six dimensions of the phenomenon that explain and differentiate the conceptions are identified: Logical reasoning, Technical knowledge (of the productive process), Systemic knowledge (of other areas), Negotiation strategy, Manifested aspect of the routine and Involvement with corporate strategy. The findings suggest that the strategic dimension of scheduling is verifiable, to different degrees, in production planning routines. In addition, by revealing the concept of competence as being the mediation between the different areas of the company, the study brings negotiation strategies to the center of the debate on the competent realization of production planning routines.

Abstract:

This study deals with chocolate production line scheduling. The particular production line allows producing multiple items at the same time. Another distinguishing property affecting the planning methodology is that an item can have different production capacities when produced in different product combinations which are called production patterns in this study. Planning is done on a 12 weeks rolling horizon. There are 21 products and 103 production patterns covering all the production possibilities. The subject of the study is to construct an algorithm that gives 12 weeks&rsquo
production values of each product and to construct the shift based scheduling of the first week of the planning horizon. The first part is Master Production Scheduling (MPS) and the objective is minimizing the shortage and overage costs. A mathematical modeling approach is used to solve the MPS problem. The second part is the scheduling part which aims to arrange the production patterns obtained from the MPS module within the shifts for the first week of the planning horizon considering the setup times. The MPS module is a large integer programming model. The challenge is finding a reasonable lower bound whenever possible. If it is not possible, finding a reasonable upper bound and seeking solutions better than that is the main approach. The scheduling part, after solving MPS, becomes a TSP and the setup times are sequence independent. In this part, the challenge is solving TSP with an appropriate objective function.

Abstract:

Bibliography: pages 89-92.
The scheduling of production in job shops is generally accomplished in four stages; aggregate planning, machine loading, sequencing and detailed scheduling. In industrial job shops, the number of jobs and machines makes detailed scheduling a particularly complicated and unwieldy task. When faced with this situation, a typical response of managements is to simply ignore the problem and apply some remedial action by adapting existing company operation procedures. The first objective of this dissertation is to indicate the dangers and inefficiencies which result when the problem of detailed scheduling is ignored. This is done in terms of a case study analysis in which the problems which currently exist in the machine shop at Atlantis Aluminium, a jobbing foundry, are illustrated. The second objective is to develop a systematic approach for the solution of detailed scheduling in job shops. Major steps in this approach are: i) a classification of shop scheduling problems ii) a survey of relevant scheduling literature in order to determine existing detailed scheduling techniques iii) the design of the scheduling system This approach is illustrated by applying it to the machine shop at Atlantis Aluminium.

Abstract:

Spatial resource allocation is an important consideration in shipbuilding and large-scale manufacturing industries. Spatial scheduling problems (SSP) involve the non-overlapping arrangement of jobs within a limited physical workspace such that some scheduling objective is optimized. Since jobs are heavy and occupy large areas, they cannot be moved once set up, requiring that the same contiguous units of space be assigned throughout the duration of their processing time. This adds an additional level of complexity to the general scheduling problem, due to which solving large instances of the problem becomes computationally intractable. The aim of this study is to gain a deeper understanding of the relationship between the spatial and temporal components of the problem. We exploit these acquired insights on problem characteristics to aid in devising solution procedures that perform well in practice. Much of the literature on SSP focuses on the objective of minimizing the makespan of the schedule. We concentrate our efforts towards the minimum sum of completion times objective and state several interesting results encountered in the pursuit of developing fast and reliable solution methods for this problem. Specifically, we develop mixed-integer programming models that identify groups of jobs (batches) that can be scheduled simultaneously. We identify scenarios where batching is useful and ones where batching jobs provides a solution with a worse objective function value. We present computational analysis on large instances and prove an approximation factor on the performance of this method, under certain conditions. We also provide greedy and list-scheduling heuristics for the problem and compare their objectives with the optimal solution. Based on the instances we tested for both batching and list-scheduling approaches, our assessment is that scheduling jobs similar in processing times within the same space yields good solutions. If processing times are sufficiently different, then grouping jobs together, although seemingly makes a more effective use of the space, does not necessarily result in a lower sum of completion times.

Abstract:

In this dissertation we present new results for minimizing the makespan in a flow shop with zero storage between machines. Makespan is the total length of time required to process a set of jobs. We consider m machines and n jobs with random processing times. Since there is no intermediate storage between machines, a job that has finished processing at one machine may have to stay on that machine until the next machine is free. Our goal is to select a schedule that will minimize the makespan. Our results require various stochastic orderings of the processing time distributions. Some orderings minimize the expected makespan, and some stronger results stochastically minimize the makespan. The optimum sequence of these latter cases not only minimizes the expected makespan but also maximizes the probability of completing a set of jobs by time t for any t. The last result is concerned with scheduling jobs on two identical parallel machines. The jobs are subjected to some intree precedence constraints. We resolve a conjecture that appeared in Pinedo and Weiss (1985) and give conditions under which the conjecture is true and give examples to prove that the conjecture is false in general.

Abstract:

This Licentiate Thesis is concerned with the lot scheduling of multiple items on a single facility, both in production and disassembly. The thesis contains an introductory overview and four research papers, entitled: I. Lot Sizes in a Capacity Constrained Facility – A simulation Study of Stationary Stochastic Demand II. Determination of Safety Stocks for Cyclic Schedules III. Lot Scheduling in a Disassembly Factory IV. Cyclic Lot Scheduling with Sequence-dependent Setups: A Heuristic for Disassembly Processes In paper I, the applicability of two deterministic lot sizing-procedures is tested in a simulation study when demands are stochastic. The paper shows that a deterministic model can be used in a practical situation where the demand rate is stationary stochastic, but the models must be complemented by a decision rule; which item to produce and when to produce it. Paper II develops a planning and control model for determination of safety stocks for cyclic schedules, both with and without idle time. The paper shows how the variance in demand during lead time can be estimated, which is used for determination of safety stocks and order-up-to levels. For systems with idle time, a control model for the decision to produce next item or idle the facility is presented. Paper III is an introduction to lot scheduling in disassembly processes. The performance of two different lot scheduling policies for the disassembly of multiple items is tested in a simulation study when setup times are sequence-dependent. It is concluded that cyclic schedules are preferable in disassembly processes with sequence-dependent setup times. In paper IV, a lot scheduling heuristic for disassembly processes with sequence-dependent setups is developed. The heuristic determines disassembly frequencies and the profitable use of the facility and results in a cyclic schedule.

Abstract:

A good methodology for production scheduling can result in high efficiency in reducing manufacturing costs. SIMEX is an experimental simulation-based expert production scheduler developed by the author for applications in flexible flow shop systems in a dynamic factory environment. This study introduces the general framework of SIMEX. A prototype is developed on an IBM compatible PC in Prolog, MODSIM II, Visual Basic, and Visual C++ to generate feasible and acceptable schedules with a synchronous data exchange facility. In general, primary tasks of SIMEX are to meet due dates of the final products, to increase throughput by reducing the number of setups, and to reduce inventory cost in a flexible flow shop system in real time. SIMEX has also an ability to change its expert system's rule base interactively by means of a user interface. The expert system module of SIMEX allows to use heuristics, and production rules which are the simplifications that help limit the search for possible problem solutions and handling unexpected events. Simulation-based scheduler written in MODSIM II, is another module of SIMEX. It generates the schedules, repeatedly, to analyze and verify proposed design and alternatives.

Abstract:

In this thesis, and complex real world problem, a sequence dependent scheduling of different product orders on a number of lines is addressed. Changeover costs occur between product orders belonging to different product groups. The operational research cycle is employed exploring different optimization techniques as mathematical modelling and heuristic approaches. The identification, implementation and demonstration of the techniques are supported with numerical results from experiments. One combination of different solution techniques is put forward. Some suggestions are done for reducing cost and increasing productivity.
