The objective of this thesis is to find an appropriate analytical method for scheduling the daily driver tasks in the grocery industry. The goal is to maximize driver utilization. A "Bin-packing" approach is employed to solve the problem. A Bin-packing problem concerns packing a list of items into the minimal number of unit capacity bins. In our problem, the drivers correspond to the bins and the daily delivery tasks are equivalent to the items, where we use time units to measure bin capacity. The model is applied to characterize the operation of a grocery company. Several bin-packing algorithms are implemented on two weeks of delivery data, which represent the company's transportation demand. The driver requirements are calculated and compared with their actual assets. Driver requirements are assessed on a per-day basis, considering the volatility in transportation demand over the course of the week. The performance of a given bin-packing algorithm is measured by how well it maximizes driver utilization and balances the workload among the drivers. The model's solution generated labor savings and proved that better resource allocation is possible by considering the demands of the various dispatching locations and the days of the week. Extension of the current model to capture the time window constraints of the delivery locations is proposed for future further research.

Resumo: O risco de acidentes rodoviários com produtos perigosos tem estimulado estudos que possam prever os locais mais críticos a essas ocorrências e seus efeitos em relação à contaminação do solo, da água e suas conseqüências à saúde humana. O mapeamento de risco é uma das formas de obter essas informações, tendo a vantagem de proporcionar uma leitura clara da informação. O presente trabalho tem como objetivo elaborar mapa que represente a potencialidade de risco de contaminação dos recursos hídricos, que poderá ser utilizado como ferramenta para os gestores de bacias nos planos de prevenção de acidentes e sistemas de alerta. Foi escolhida como área de estudo a bacia hidrográfica do rio Cotia em virtude da sua importância para o abastecimento de água da zona oeste da Grande São Paulo, além de ser uma área com grande desenvolvimento industrial no eixo da rodovia Raposo Tavares, que corta a bacia. O mapa foi obtido por meio da utilização da metodologia de Sistemas de Informações Geográficas (IDRISI 3.2), o qual foi produzido com uma visão genérica da problemática, dando maior importância às vias de maior tráfego em relação aos recursos hídricos, a declividade da área e a permeabilidade de solo. O mapa elaborado demonstrou ser capaz de representar a potencialidade ao risco de contaminação de determinada área, podendo ser usado como ferramenta no auxílio da prevenção e remediação de acidentes. Esta metodologia pode ser adaptada para outras bacias, subsidiando os gestores a alocar equipes e recursos para o atendimento emergencial, agilizando o processo de resgate e contenção de produto e também pode ser utilizado no planejamento de outras bacias
Abstract: The highway accidents risk with hazardous materials have been stimulating studies to forecast what are the critical locations that these accidents can occur and how they affect the soil and water contamination, as well as their consequences to human health. One way of getting a clear picture of this information is the risk mapping. This study aims to elaborate a risk map of potential water resources contamination, and can be used by watershed managers in the accident prevention and alert system. Due to its water supply importance to the west of the Metropolitan Region of São Paulo and because of its significant industrial development around the Raposo Tavares highway, the Rio Cotia watershed was chosen for this study. The methodology is based on the Geographic Information System (IDRISI 3.2), and the map was elaborated with a generic view of the problem, focusing on roads with heavy traffic near water resources, local slope and soil permeability. The map elaborated represents the contamination risk potential of the studied area, and can be used as a support tool in accident prevention and remediation. This methodology can be adapted to other basins, allowing managers to relocate teams and resources in case of emergency and accelerating the product rescue and restrain. It can also be used for other water basins planning

Texte intégralThe fast changes produced by the technological development and by the globalization process highlight the need for a new profile of an engineer that can meet the demands of the labor market and of the society. The emergence of new techniques and analyses tools is a natural consequence of that technological and scientific development and it should be immediately incorporated into courses with a strong technological basis, such as Engineering. The challenge to do so is the time constraint imposed to disciplines, which can no longer be increased to include additional topics. However, the hypothesis of this research is that although the new technologies are part of the problem, they can also provide the resources needed for its solution. In such a context, a new paradigm for the teaching learning process is required, in which not only the potential role of the computer itself and of the tools associated to are acknowledged, but also the different learning styles of the students should be taken into account. Therefore, the objective of this research work is to search and evaluation of alternatives for adapting the teaching-learning process to the context of fast and constant innovations currently observed. This is achieved by using multimedia resources for exploring concepts of constructivism, tested with the inclusion of innovative concepts in a Transportation Planning discipline. This experiment was meant to evaluate if the students would be able to grasp new topics along with the long-established contents with the proposed approach. The traditional paradigm was then combined with several pedagogical alternatives (team work, educational CD-ROM, research on Internet, WebCT, etc.) in a Civil Engineering attended by third-year students. The results found indicate that the alternatives considered have contributed to some extent, to the improvement of the traditional teaching method, bringing positive outcomes to the learning process. Therefore, one can conclude that this study brought a valuable contribution for Transportation Engineering education, given that the teaching-learning process was improved while making possible the inclusion of new topics even in a very inflexible grid course.

Resource optimization has always been a challenge both in traditional fields, such as logistics, and particularly so in most emerging systems in the sharing economy. These systems are by definition founded on the sharing of resources among users, which naturally creates many coordination needs as well as challenges to ensure enough resource supply to cover customer demand. This thesis addresses these challenges in the application of vehicle sharing systems, as well as in the context of multi-operation companies that provide a wide range of services to their users. More specifically, the first part of this thesis focuses on models and algorithms for the optimization of bike sharing systems. Shortage of bikes and docks is a common issue in bike sharing systems, and, to tackle this problem, operators use a fleet of vehicles to redistribute bikes across the network.
We study multiple aspects of these operations, and develop models that can capture all user trips that are performed successfully in the system, as well as algorithms that generate complete redistribution plans for the operators to maximize the served demand, in running times that are fast enough to allow real-time information to be taken into account. Furthermore, we propose an approach for the estimation of the actual user demand which takes into account both the lost demand (users that left the system due to lack of bikes or docks) and shifted demand (users that had to walk to nearby stations to find available resources). More accurate demand representations can then be used to inform better decisions for the daily operations, as well as the long-term planning of the system. The second part of this thesis is focused on schedule generation for resources of large companies that must support a complex set of operations.
Different operation types come with a variety of constraints and requirements that need to be taken into account. Moreover, specialized employees with a variety of skills and experience levels are required, along with an heterogeneous fleet of vehicles with various properties (e.g., refrigerator vehicles). We introduce the Complex Event Scheduling Problem (CESP), which captures known problems such as pickup-and-delivery and technician scheduling as special cases. We then develop a unified optimization framework for CESP, which relies on a combination of metaheuristics (ALNS) and Linear Programming. Our experiments show that our framework scales to large problem instances, and may help companies and organizations improve operation efficiency (e.g., reduce fleet size).

Texte intégralI denna rapport försöker vi ge insikter om hur en resurseffektiv lösning för transportlägesigenkänning kan implementeras på en smartphone genom att använda accelerometern och magnetometern som sensorer för datainsamling. Det föreslagna systemet använder en hierarkisk klassificeringsprocess där instanser först klassificeras som fordon eller icke-fordon, sedan som hjul- eller järnvägsfordon, och slutligen som tillhörande ett av transportsätten: buss, bil, motorcykel, tunnelbana eller tåg. Ett virtuellt gyroskop implementeras som en lågenergi källa till simulerad gyroskopdata. Olika särdrag extraheras från accelerometer, magnetometer och virtuella gyroskopläsningar som samlas in vid 30 Hz, innan de klassificeras med hjälp av maskininlärningsalgoritmer från WEKA-maskinlärningsbiblioteket. En Android-applikation har utvecklats för att klassificera realtidsdata, och programmets resursförbrukning mättes med hjälp av Trepn profiler-applikationen. Det föreslagna systemet uppnår en övergripande noggrannhet av 82.7% och en fordonsnoggrannhet av 84.9% genom att använda ett 5 sekunders fönster med 75% överlappning med en genomsnittlig energiförbrukning av 8.5 mW.

Texte intégralDe senaste årens framsteg inom autonom körteknik har lett till mer mogna autonoma fordon. Dessa fordon har setts tillämpas i flera pilotprojekt över hela världen, oftast i form av små bussar. Samtidigt växer mängden människor som reser, särskilt i stadsområden, kontinuerligt vilket resulterar i fler resor i transportsystemet. Därför krävs ett effektivt transportsystem för att tillgodose det växande antalet passagerare. Autonoma bussar (AB) antas ha lägre driftskostnader och därmed kan system för kollektivtrafik (public transport, PT) potentiellt utformas mer effektivt för att underlätta den ökade efterfrågan bättre. I denna studie föreslås ett AB-specifikt simuleringsbaserat optimeringsramverk som gör det möjligt att analysera effekterna AB har på linjebaserade PT-system. Avhandlingen fokuserar på övergången från befintliga PT-system till linjebaserade PT-system som delvis eller uteslutande drivs av AB. Befintligt arbete med PT-tjänstdesign utvidgas så att realistiska AB-system kan undersökas. Detta uppnås genom att (i) använda AB-specifika operatörskostnadsformuleringar, (ii) integrera infrastrukturkostnader som krävs för AB-verksamhet, (iii) använda en dynamisk, stokastisk och schemabaserad modell för att tilldela passagerare vid simulering av PT-nät samt genom att (iv) formulera ett multifunktionellt optimeringsproblem som gör det möjligt att undersöka AB: s intressespecifika effekter. I artikel I undersöks effekterna av AB, med avseende på servicefrekvens och fordonskapacitet, på fasta linjer i PT-nät. Förändringar utvärderas bland annat utifrån skillnader i servicenivå och passagerarflöde. Dessutom studeras den sekventiella introduktionen av AB i befintliga PT-system. Det föreslagna ramverket tillämpas på en fallstudie i Kista, Sverige. Studien bekräftade den initiala hypotesen att utplaceringen av AB leder till en ökning av servicefrekvensen och en marginell minskning av fordonens kapacitet. Vidare kunde man se att utplaceringen av AB ökar passagerarbelastningen på AB-linjer och att passagerare kan skifta från andra PT-former mot AB-tjänsterna. Artikel II integrerar en multifunktionell heuristisk optimeringsalgoritm i ramverket för simuleringen. Studien undersöker förändringar i transportnätverkets design baserat på implementeringen av AB. Skillnaderna i användarfokuserad och operatörsfokuserad nätverksdesign analyseras och AB: s inverkan på dessa kvantifieras. Denna studie tillämpas på en fallstudie i Barkarby, Sverige, där ett fullstort linjebaserat PT-nät är utformat för att exklusivt driva AB. Vi visar bland annat att den autonoma tekniken reducerar antalet använda busshållplatser och reducerar den totala PT-nätstorleken. Dessutom kan implementeringen av AB på användarfokuserade PT-nät ytterligare förbättra servicenivån främst genom att minska den genomsnittliga väntetiden per passagerare.

Texte intégralMetaheuristics are optimization problem-solving methods that primarily rely on an abstract representation of solutions in the form of direct or indirect encoding. Improving a solution or a set of solutions in parallel is achieved through manipulations of these encodings and algorithms evaluating the quality of associated solutions. The transition from one solution to another involves the use of one or more operators to explore the search space. Generally, metaheuristics utilize these operators to iteratively enhance solutions until reaching a local (or global) optimum. A plethora of metaheuristics has been proposed to address combinatorial optimization problems, including task scheduling problems. These ones are often dedicated to specific classes of instances. In this context, researchers frequently propose algorithms that combine various methods, striving to optimize parameters across different parts of their algorithms. However, the achieved performance is often comparable, and efficiency depends on the class of instances addressed. While solution encodings and neighborhood operators are recognized as essential components within metaheuristics, they are rarely jointly examined in an analytical and scientific manner.This thesis aims to characterize solution encodings and neighborhood operators commonly used in scheduling, particularly for the job shop problem and for one of its variants, in which the objective is to minimize the makespan. The ambition is to exploit the properties of the search spaces induced by these encodings and operators to enhance the design of metaheuristics. The approach applied in our study is structured into two main parts, with a gradation in the complexity of the job shop problem. The first part focuses on characterizing search spaces through a fitness landscape analysis, using metrics from the literature. The second part involves evaluating the performance of various combinations of encodings and neighborhood operators with the aim of identifying potential correlations with landscape properties. This is done to provide recommendations for the design of metaheuristics. This approach is initially applied to a basic job shop and then to a more constrained variant: the flexible job shop with transportation constraints. Our work highlights the challenge of linking the performance of tested combinations with standard metrics. The comparison of results obtained for the basic problem and its more constrained variant leads us to express reservations about a systematic generalization of encoding and operator characteristics for this category of optimization problems

Texte intégralThe growing complexity of the global mobility is a key challenge for the understanding of the worldwide spread of emergent infectious diseases and the design of effective containment strategies. Despite global connectivity, containment policies are often based on national, regional and ’egocentric’ assessments of outbreak situations that are no longer effective or meaningful, as recently demonstrated by 2014 Ebola outbreak in West Africa, where months passed before a concerted, international effort followed. Despite the importance of the matter, optimal strategies in highly connected non-local settings are poorly understood. In the work at hand we propose a set of methods for more informed decision making during and prior to a pandemic. All of the studied systems are represented by networks in analogz the traffic networks, which play a dominant role during the global disease spreading. We introduce methods to calculate the risk of disease importation in a specific location and to determine the role of a node during an outbreak. Using the world aviation network, we demonstrate how the methods can be applied on real and hypothetical pandemics. We show that the airports can be divided into two distinct groups according to the role they take on in distributing the disease. Further, investigate the allocation of resources as a game theoretic dilemma. We embrace a bottom-up approach to this question, allowing the nodes of the network to distribute the resourses. We investigate egocentric and altruistic strategies and conclude that the optimal state of both systems are very similar if the outbreak is spacially confined. In this case allocation of resources ti the affected nodes is the optimal strategy. When there are multiple independent outbreaks, the optima diverge substantially. To foster the benefits of multiple approaches, the work at hand combines the information on the network topology but also regard some specifics of the outbreak at hand outbreak.

Texte intégralThe planning of railway production at the french national railways (sncf) is currently based on a mainly sequential process in which the design of railway timetabling widely conditioning design planning of railway equipment (rolling stock), then one of the train drivers (driver rosters). this strategy of sequential planning of railway resources massively adopted for practical and scientific reasons (expertise, complexity of the railway system, etc.). however, this strategy generates solutions which can be more expensive and less robust to uncertainties, because decisions taken at any given stage can significantly reduce the overall feasible solutions of the following steps.given this situation and the strong interaction between these heterogeneous and very expensive resources, the thesis deals with the feasibility and inputs of a process where these critical resources could be planned and optimized in an integrated way. the thesis focuses on the feasibility study, prototyping and validation of an integrated approach for planning rolling stocks and drivers, so as to improve the efficiency of the overall transportation plan, increase sncf competitiveness and enhance the quality of its services. we propose a mixed integer linear programming formulation of the rolling stock/ train drivers integrated planning problem. in this mathematical model, each planning sub-problem is formalized and coupling constraints are further introduced to model the interdependencies of these two resources when they are simultaneously used for train production. in this heuristic, the solution of the lagrangian dual and the calculation of feasible solutions are performed by calling two proprietary software modules available at sncf for planning rolling stocks and train drivers. the heuristic is tested experimentally with real data from the ter bretagne region, and several evolutions are introduced in the models and algorithms so as to improve their performances.validation tests on of real data sets at an industrial scale are encouraging and, when compared to a traditional (sequential) approach, show gain of up to 4% for train drivers used

Texte intégralДиссертация посвящена исследованию теоретических и прикладных принципов управления производственными запасами материально-технических ресурсов субъектов нефтегазового комплекса Украины. В работе обобщенно теорию и практический опыт разработки методических подходов к построению управления многономенклатурными производственными запасами с точки зрения междисциплинарного подхода, а именно: экономической теории, бухгалтерского учета, финансового анализа, статистического и эконометрического анализа и прогнозирования, логистики. Проведен анализ профессиональной литературы, который показал зависимость сущности категории «производственные запасы» от производственных программ предприятий, и, как следствие — наличие функциональной зависимости (обслуживающая или комплектующая). Для определения ресурсной части материально-технического обеспечения с обслуживающим характером производственного цикла добычи и транспортировки природного газа, предложено следующее толкование категории «производственные запасы» - под производственными запасами МТР следует понимать продукцию производственно-технического назначения, которая сохраняется и учитывается в складских хозяйствах газодобывающих и газотранспортных предприятий и подготовления для выполнения работ, предоставления услуг, обслуживания производства и административных потребностей. Обосновано функции маркетинга материально-технического обеспечения, которое дает основания рассматривать его как отдельное направление в снабженческо-сбытовой деятельности предприятий. Систематизированы существующие модели по регулированию объемов производственных запасов. Обоснование практического применения моделей позволили рекомендовать модели ABC, MRP, MRPII, ERP в области производственных запасов на газодобывающих и газотранспортных предприятиях. Усовершенствована классификация производственных запасов МТР для газодобывающих и газотранспортных предприятий по соответствующим классификационным признакам: местонахождение, направление использования в производстве, по экономическим признакам, по группам товаров, однородных по техническим признакам, которая в отличие от существующих классификаций запасов, обеспечивает унификацию показателей при работе с многономенклатурными производственными запасами в сложных иерархических системах. Предложен подход, который является актуальным в современных условиях развития сферы материально-технического обеспечения, — переход к отраслевым стандартам закупки товаров, работ и услуг. В результате проработки литературных источников и изучения практики выбора поставщиков, которые могли бы эффективнее всего обеспечить успешную деятельность предприятия, разработана схема отбора поставщиков для практического применения при предварительном квалификационном отборе участников открытых торгов. Проведен анализ объемов производственных запасов в структуре газодобывающих и газотранспортных предприятий. Определена степень связи и зависимости между закупкой материально-технических ресурсов и складскими производственными запасами методом корреляционно-регрессионного анализа. На основе построенных моделей взаимосвязей экономических показателей деятельности исследуемых предприятий, осуществлены прогнозные расчеты и дана объективная оценка эффективности производственных запасов в деятельности хозяйствующих субъектов в условиях рыночных отношений. Разработаны формы управленческой отчетности, ставшие основой создания управленческого учета на предприятиях в сфере материально-технического обеспечения. Определены пути повышения эффективности логистических процессов в складских хозяйствах предприятий. Научно обосновано методические рекомендации относительно рационального финансового обеспечения производственных запасов. Разработан инструментарий для внедрения путей повышения экономической эффективности в хозяйственной деятельности газодобывающих и газотранспортных предприятий, при условиях управления производственными запасами МТР и сопутствующими финансовыми процессами. Даны практические рекомендации относительно организации контроля в области управления производственными запасами. Разработана сбалансированная система показателей, основой которой является совокупность независимых модулей, сгруппированных за сформированными критериями, которые в отличие от существующих разрозненных показателей, смогут обеспечить прямую и обратную связь от финансового контроля деятельности предприятий в сфере управления производственными запасами к управленческому контролю. Построена модель организационно-экономического обеспечения управления производственными запасами, направленная на реализацию стратегии, создание корпоративной культуры и которая позволит предприятиям использовать все возможности современного управления.
Dissertation has been concentrate on the investigation of the theoretical and practical methods of production reserves management of the material and technical resources (MTR) of entities in oil & gas complex Ukraine. It has been elaborated conceptual methods for the buildup of strategic targets in management of productive supplies MTR which based on the principle of profit maximization as newly seen oriented influence upon this process what give us opportunity to enlarge basic terms which absent in strategy of oil&gas complex (OGC) development. Elaborated forms of management reporting would became the basis for the system management calculation in the enterprises in the sphere of productive supplies. It has determined priorities for the effective functioning of enterprise warehousing. Scientifically justified methodical recommendations for the efficient financial cover of productive supplies. There were build up the model of business support of management of productive supplies basis of which are summarizing of independent modules, grouped according to the measures which as distinct from present segmental indexes could achieve transition from financial control of enterprises activity in the sphere of productive supplies to the managerial and vice versa.

Texte intégralThis dissertation had the objective to study methods of transport cost allocation on milk collection in order to deepening and debating about several ways usually used and new ways to proceed the allocation, such as Activity Based Costing methodology. Methodologies traditionally used consider volume or distance to allocate costs to farmers generating distortions that penalize some farmers and benefit others in many cases. This has happened because traditional methodologies do not require knowledge about logistic process of milk collection to be applied. However, the Activity Based Costing methodology contributes to cost allocation process by taking into account variables as volume, distance and time. In addiction, the ABC methodology has managerial function by demanding a well-known logistic process allowing, in this way, to identify the most costly activities. The comparison between traditional methodologies and ABC methodology took place through a case study applied to Cooperativa dos Produtores Agropecuários de São Pedro COOPAMSP, that had 46 farmers producing milk in three routes (L1, L2 and L3), in the period of time that was considered. The results obtained by comparison between cooperative's methodology, that allocates costs in direct proportion to volume, and ABC methodology are emphasized. The methodology used by the cooperative allocates the highest costs to the more efficient route (L1) in aid of less efficient farmers (L2 and L3). That distortion does not happen when ABC methodology is used.

Texte intégralThe present work focuses on optimal management, resource sharing and conflicts resolution in Discrete Event Systems (DES). We mainly focus on public transportation systems and supply chains. The main objective of this work is to develop a generic approach to represent the functioning of a DES in a real and dynamic context, with fewer simplifying assumptions. More precisely, we aim to develop theoretical models, describing the behavior of the real system characterized by different phenomena including conflicts and resource sharing. In order to solve these phenomena, we develop algorithms and routing policies to arbitrate conflicts and thus determine and control the different states of the system. To this end, we propose a new modelling approach combining colored Petri nets and (max, +) algebra. The obtained models make it possible to study and evaluate the behavior of the system and therefore prove its performance properties. As a second contribution, and in order to improve the performance of the system, a control approach based on residuation theory in dioid algebra is developed. The purpose of this control is to ensure a certain performance both for users, in terms of waiting times and travel times, and for companies in terms of the number of transportation means to deploy in the network (vehicles, etc.) in order to minimize their costs. The developed models are generic and can be applied to any public transportation network (bus network, rail network, multimodal network, etc.) of any size. Similarly, these models are adapted to supply chain networks in order to minimize storage and transport times for goods in different warehouses and distribution hubs. Illustrative examples are given to show the applicability of the proposed approach and the obtained results are promising. These examples enables the verification and the validation of the developed models through concrete scenarios. Finally, a simulation tool, based on established models and programmed with python, is developed. This tool is used to study, analyze and control DES, particularly public transportation systems and supply chains
