Vehicle Routing for City Logistics / OPTIMISATION DE TOURNEES DE VEHICULES POUR LA LOGISTIQUE URBAINECattaruzza, Diego 27 March 2014 (has links)
Le transport de marchandises dans les zones urbaines est un sujet important de nos jours. Le transport est une activité vitale pour les villes, mais implique pollution, congestion, accidents. La logistique urbaine vise à optimiser les processus logistiques et de transports urbains en tenant compte des aspects environnementaux et sociaux. Cette thèse traite de cette thématique et fait partie du projet MODUM.MODUM vise à étudier un système de livraison basé sur des centres de distribution urbains. Nous présentons une classification et une analyse des mouvements de marchandises et des problèmes de tournées de véhicules (VRP) associés.La deuxième partie propose une revue complète des travaux de recherche traitant des problème VRP avec excursions multiples (MTVRP). Le MTVRP est une extension du VRP où les véhicules sont autorisés à effectuer plusieurs tournées. Nous proposons une heuristique pour le MTVRP qui est par la suite adaptée pour un problème plus riche, le MTVRP avec fenêtres de temps et dates de disponibilité. Il s'agit d'une variante du MTVRP où à chaque client est associée une fenêtre de temps et à chaque marchandise une date de disponibilité qui représente l'instant où elle devient disponible au dépôt.Par la suite, nous étudions une variante du MTVRP où les marchandises sont classées par types de produits qui ne peuvent pas être transportés dans le même véhicule. Une analyse est effectuée pour montrer l’avantage des tournées multiples pour le problème de dimensionnement des flottes.Enfin, nous décrivons le problème de tournées qui se pose dans MODUM et le simulateur qui est développé pour évaluation du système. / Transportation of merchandise in urban areas has become an important nowadays topic. In fact, transportation is a vital activity for each city, but entail pollution, congestion, accidents.City logistics aims at optimizing the whole urban logistics and transportation process, taking into account environmental and social aspects. This thesis, that is part of the MODUM project, finds its location in this area of research. In particular, MODUM aims at studying a delivery system based on City Distribution Centers.We first present a classification and an analysis of urban good movements and routing problems peculiar to metropolitan areas. A second survey proposes a complete collection of articles that has been done on the Multi Trip Vehicle Routing Problem (MTVRP). The MTVRP is an extension of the Vehicle Routing Problem (VRP) where vehicles are allowed to perform several trips.We propose an efficient heuristic for the MTVRP that is, in a subsequent step, adapted to a new routing problem, the MTVRP with Time Windows and Release Dates (MTVRPTWR). It is a variant of the MTVRP where each customer is associated with a time window and each merchandise is associated with a release date that represents the instant it becomes available at the depot.We, then, study a variant of the MTVRP where goods belong to different commodities that cannot be transported at the same time by the same vehicle. An analysis is conducted on the benefits of the multi-trip aspect in fleet dimensioning problems.Finally we describe the complex routing problem that arises in MODUM and the simulator that is developed to evaluate the performances of the system.

Evaluation and assessment of relocation from a city to the outskirts: Case study DHL Gävle (Sweden)Syed, Haseeb Ahmed, Ajifowowe, Olanrewaju John January 2018 (has links)
The ‘City Logistics’ activities are contributing to traffic congestion and accumulating to environmental challenges, such situation has prompted the creation of urban consolidation centre (UCC), as a multimodal logistics park facility in the outskirts. The relocation of business from a city to the outskirts requires the evaluation and assessment of the key factors in order to make the better decisions. However, no relocation decisions evaluation model has been found, neither its application on the case company to find the effects of relocation on the logistics firms. This study is aimed at developing general business relocation model, that can be used by logistics firms, to evaluate the effects of their relocation. The model is a decision making tool. Application of the model before the relocation, help’s in decision making. Therefore, this research study focuses on developing a general model involving selected important factors that can be considered by logistics firms to evaluate the effects of relocation. The results for this research were analysed using the qualitative method, predominantly literature review, factors were applied on the case company. The DHL’s relocation scenario from Gävle city centre (Näringen) to the proposed Tolvfors Logistics Park (outskirts), relocation led to transport cost and drive-time reductions, along with efficiency improvements. The evaluation model has been developed, have likewise presented the drivers of relocation, and factors that logistics firms can consider for relocation’s possible outcome.

Previous issue date: 2017-03-10 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) / The streets historic cities are designed to support only the traffic of animal-dragged vehicles and few pedestrians. However, the heavy flow of vehicles in these cities leads to negative impacts for city logistics and for the preservation of its built heritage. These impacts are more perceived in the historical center, which is the oldest place in the cities, usually characterized by narrow streets, winding trails and, in some cases, sloping terrain, in addition to being the place where there is a predominance of commercial and administrative activities. A possible solution to minimize these impacts, particularly those related to freight transport, is the implementation of an Urban Distribution Center (UDC). However, prior to the effective implementation of a UCD, it is necessary to do a study about the conditions that may favor its use and to understand the views of stakeholders involved directly or indirectly in this process. The main objective of the study is to analyse the relevant criteria to be considered in the implementation of a CDU to supply the Brazilian historical cities, taking the example of the historic center of Ouro Preto, which is considered a reference to the other historical cities. For this, based on the perception of sustainability (economic, social and environmental), technical and historical criteria reported in the literature, is done a survey with retailers, carriers, residents, and municipal guards of Ouro Preto. Five semi-structured interviews are also carried out: three with public authorities related to freight traffic in the city, one with a manager of the commercial association and another with the head of the office of Iphan, a Federal autarchy that aims to ensure the preservation of the historical heritage of Ouro Preto. To find the relevant criteria, a descriptive analysis and a factor analysis is applied. Moreover, the qualitative analysis of interviews, and the literature review will be used to correlate the results. It is concluded that residents and municipal guards have similar point of views while retailers and carriers diverge opinions among themselves and among the other agents. The carriers have also shown against the existence of the negative impacts of transport. The variables that presented at least 75% of agreement among all the agents were: increase of the level of service; local prosperity; total investments and costs; use of technologies and vehicle size. The factors found for retailers and residents showed little correlation, reinforcing the different points of view of these agents. However, it should be noted that the most striking factor for both agents was related to the concern for the preservation of historical patrimony, by representing 14.31% of the variance in the set of all variables of the retailers and 21.12% of the common variables of the retailers; in the case of residents, this factor explained 23,38% of the all variance. / As vias das cidades históricas foram projetadas para suportar apenas o tráfego de veículos de tração animal e poucos pedestres. Entretanto, o fluxo intenso de veículos existente nessas cidades acarreta impactos negativos tanto para a logística urbana quanto para a preservação do seu patrimônio. Esses impactos são mais percebidos nos centros históricos, isto é, o local mais antigo das cidades, geralmente caracterizado por ruas estreitas, traçado sinuoso e, em alguns casos, terreno inclinado, além da predominância de atividades comerciais e administrativas. Uma possível solução para conter tais impactos, particularmente aqueles relacionados ao transporte de carga, é a instalação de um Centro de Distribuição Urbana (CDU). Contudo, antes da implantação efetiva de um CDU é preciso estudar as condições que possam favorecer o seu uso e entender a visão dos agentes envolvidos direta ou indiretamente nesse processo. Posto isso, o objetivo principal do estudo é analisar os critérios relevantes na implantação de um CDU para atender cidades históricas brasileiras, tendo como exemplo o caso do centro histórico de Ouro Preto, considerada como cidade referência para as demais cidades históricas do país. Para isso, utilizando como base a percepção de critérios de sustentabilidade (econômicos, sociais e ambientais), técnicos e históricos identificados na literatura, é realizada uma survey com os seguintes agentes: varejistas, transportadoras, residentes e guardas municipais. Também são realizadas cinco entrevistas semiestruturadas: três com autoridades públicas relacionadas ao tráfego de veículos de carga na cidade, uma com um representante da associação comercial e outra com o chefe do escritório do Iphan, autarquia federal que visa assegurar a conservação e preservação do patrimônio histórico de Ouro Preto. Para encontrar os critérios relevantes, é aplicada a análise descritiva e a análise fatorial exploratória. A análise qualitativa das entrevistas, unida ao material bibliográfico foi utilizada para corroborar os resultados encontrados. Conclui-se que residentes e guardas municipais possuem pontos de vista semelhantes enquanto varejistas e transportadoras divergem opiniões entre si e em relação aos demais agentes. Os motoristas de veículos de carga também atenuaram a existência dos impactos negativos do transporte. As variáveis que apresentaram pelo menos 75% de concordância entre todos os agentes foram: aumento do nível de serviço; prosperidade local; total de investimentos e custos; uso de tecnologias e tamanho do veículo. Os fatores encontrados para varejistas e residentes apresentaram pouca correlação, reforçando os diferentes pontos de vista desses agentes. Ressalta-se, porém, que o fator mais impactante para ambos agentes foi o que estava relacionado à preocupação pela preservação do patrimônio histórico, representando 14,31% da variância no conjunto de todas as variáveis dos varejistas e 21,12% das variáveis comuns dos varejistas; no caso dos residentes, este fator explicou 23, 38% da variância.

Um modelo de localização-roteirização de instalações de transferência para distribuição de carga urbana baseado no método de cluster-first route-second. / A location-routing model for urban distribution centers based on the cluster -first route- second method.Fabiana Takebayashi 17 November 2014 (has links)
O trabalho apresenta o desenvolvimento e a aplicação de um modelo de localização de centros intermediários de consolidação e redistribuição de cargas em um ambiente urbano brasileiro. O método integra o TransCAD e o OpenSolver e é aplicado à cidade de Curitiba, uma das dez mais populosas do Brasil. O método proposto é caracterizado como um modelo de localização-roteirização baseado em agrupamento e subsequente roteirização, identificado na literatura por cluster-first routesecond; a adoção deste ordenamento permite tratar o problema para o atendimento de muitos estabelecimentos, como os até 65 mil em alguns dos cenários no estudo de caso de Curitiba. Cada agrupamento representa os pontos a serem visitados em uma única viagem e o processo inicial tenta minimizar as distâncias entre os estabelecimentos de cada grupo; na fase seguinte o melhor roteiro é computado para cada grupo; a terceira etapa consiste em calcular, para cada grupo e candidato, a distância total percorrida na viagem; por fim, a implantação ou não dos candidatos a centros de distribuição é obtida com a minimização em um modelo de programação linear inteira dos custos de aquisição e de operação dos centros de distribuição e dos custos de transportes. A dissertação também aborda a crescente percepção da importância da logística urbana à qualidade de vida nas cidades onde o adensamento populacional acirra a disputa pelo espaço viário e o conceito de City Logistics, que delineia entre outras medidas o ambiente cooperativo no qual implantação de centros de distribuição urbanos deve ocorrer. / This work presents the development and application of a model for the location of intermediary consolidation and redistribution freight centers in Brazilian cities. The method integrates TransCad and OpenSolver, and its use was evaluated with data from the City of Curitiba one of the ten largest in Brazil. The proposed method is characterized as a location-routing model based on clustering and subsequent tour building known as cluster-first route-second. This enables dealing with problem instances containing as many as 65 thousand customers. Each cluster comprehends the points visited on a single trip and the initial process minimizes the distances between customers; the routes are calculated in the next phase and the third step consists in computing the total distance covered in each trip for every cluster and every candidate; finally, the implementation of each distribution center candidate is decided by minimizing the costs of acquisition, operation and distribution, using an integer linear programming model. The dissertation also highlights the growing realization of the importance of urban freight transport to quality of life, especially in cities where increasing population density intensifies the competition for road space, and City Logistics concepts, that outline among other measures the cooperative environment where implementation of urban distribution centers should occur.

Urban freight consolidation platforms as a means of decreasing costs and enhancing performance of urban logistics chains within the framework of a market economy: Application to Brussels-CapitalJanjevic, Milena 27 June 2016 (has links)
Les centres de consolidation urbaine sont une mesure populaire dans la logistique urbaine visant à rationaliser les trajets liés aux livraisons en ville. Cependant, bien que les avantages environnementaux de ce type de dispositifs ont été largement abordés et documentés, un nombre important de cas d’implémentation n’ont pas parvenu à atteindre une participation suffisante et démontrer un modèle de fonctionnement viable. Les principaux obstacles liés à leur mise en œuvre relèvent des préoccupations financières et de l’acceptation de la part des acteurs de la logistique urbaine. Par conséquent, le succès de ces schémas logistiques est souvent conditionné par un fort soutien réglementaire et financier des pouvoirs publics. Récemment, de nouveaux types de modèles d'exploitation des centres de consolidation urbaine, proposant une gamme d'activités à valeur ajoutée, sont apparus, permettant une meilleure intégration de ces plateformes dans la chaîne d'approvisionnement. En outre, un grand nombre d'expériences récentes se concentrent sur la consolidation de fret à petite échelle, ce qui permet un assouplissement des besoins en ressources matérielles et humaines. L'objectif de cette thèse est d'étudier le potentiel des plates-formes de consolidation de fret urbaines de diminuer les coûts et d'améliorer les performances des chaînes logistiques urbaines. En particulier, la thèse traitera des facteurs qui influent sur la viabilité de ces schémas logistiques dans le cadre d'une économie de marché.La thèse est structurée autour de trois questions de recherche qui portent sur (1) la viabilité du modèle traditionnel du centre de consolidation urbain basé sur les activités de transbordement et de consolidation, (2) les impacts des mesures qui visent à soutenir la mise en œuvre des schémas de consolidation et le niveau d’approbation des acteurs de la logistique urbaine qui en découle, (3) l’impact des nouvelles approches dans le domaine de plates-formes de consolidation de marchandises en ville et en particulier des nouveaux modèles d’exploitation de centres de consolidation urbains et des plates-formes de micro-consolidation. En abordant ces aspects, la thèse démontre que le modèle du centre de consolidation urbain traditionnel peut présenter une alternative viable, mais que le succès de ces schémas logistiques est soumis à un grand nombre de conditions qui sont difficiles à satisfaire en pratique. La thèse identifie les mesures d'accompagnement qui peuvent à la fois accroître la participation dans le schéma de consolidation et l'acceptation des acteurs, ainsi que celles qui rencontrent une réponse plus mitigée de la part des acteurs. Enfin, la thèse identifie les avantages potentiels des nouveaux modèles d’exploitation de centres de consolidation ainsi que les avantages de la consolidation à petite échelle. / Urban consolidation centres are a popular measure in city logistics, which aims at rationalizing delivery trips in an urban area. However, although their environmental benefits have been extensively addressed and documented, many of the implementation cases fail to reach sufficient participation and demonstrate a viable business model. Some of the main barriers linked to their implementation are the financial concerns and the stakeholder acceptance. Consequently, the success of these schemes has often been subject to a strong regulatory and financial support from public authorities. Recently, new forms of urban consolidation centre operating models offering a range of value-added activities have appeared, allowing a better integration of these facilities in the overall supply chain. Furthermore, a large number of recent experiments focus on small-scale freight consolidation, relaxing the requirements for material and human resources. The objective of this thesis is to investigate the potential of urban freight consolidation platforms to decrease the costs and improve the performance of urban logistics chains. In particular, the thesis will address factors that influence the viability of these schemes in a framework of market economy.The thesis is structured around three research questions that address (1) the viability of the traditional urban consolidation centre model based on transhipment and consolidation activities (2) the impact of market-based accompanying measures for urban consolidation centre project implementation and the resulting level of stakeholder support and (3) the impact of new approaches in urban freight consolidation platforms and in particular those of new urban consolidation centres operating models and micro-consolidation platforms. By tackling these aspects, the thesis demonstrates that the traditional urban consolidation centre model can present a viable alternative but that the success of the scheme is subject to a large number of requirements that are often difficult to meet in practice. The thesis highlights accompanying measures that can both increase the expected participation in the consolidation scheme as well as the stakeholder acceptance of the scheme, and those that meet a less positive stakeholder response. Finally, the thesis identifies the potential benefits of new operating models of urban consolidation centres and of small-scale consolidation. / Doctorat en Sciences de l'ingénieur et technologie / info:eu-repo/semantics/nonPublished

City logistika v Paríži / City logistics in ParisŠkopová, Anna January 2011 (has links)
Diploma thesis indicates on traffic problems that arise not only in the huge world metropolis but increasingly appeal in smaller towns. They cause not only time and money losses but also irreversible environmental damages. This issue represents a big challenge not only for cities, transport companies, logistics service providers but also for each human being in the world. The thesis focuses on the utilization of a relatively new concept called city logistics, which should be the key for improvement of traffic situation in the cities through a higher level of transport organization and its management, cooperation between the parties and the search of new forms of transport, which don't support just the economic part of certain territory, but also brings sustainable development of transport in the future. While some cities try to become familiar only in theory, others have already obtained positive effects of its implementation. To those progressive cities belongs as well Paris to which I paid attention in diploma thesis.

Previous issue date: 2018-02-28 / The sustainability of cities depends on the logistics aspect related to the transportation of people residing in peripheral regions of large municipalities and who need attention regarding access to goods and services, whether public or private. In the particular case of the elderly residents far from the center of the city of São Paulo they go through the difficulty of aging itself, the question of recklessness in the face of low security in the most central area of the city, lack of public transportation options, distances extended by human growth and inaccessibility to public and private services. We investigated the issue of the elderly with hearing problems who need care to acquire hearing aids and the maintenance of such equipment. The general objective is to present the elements, based on the three pillars of sustainability (Triple Bottom Line), which can contribute to the improvement of the provision of goods and services to elderly people who use hearing aids and live in peripheral regions of the city of São Paulo. Methodologically, the research was based on a mixed approach: qualitative and quantitative, and also based on bibliographic review, documentary analysis and statistical analysis from a field survey and structured questionnaire application. From the economic point of view, the company under study provided new possibilities and new real gains with the new sales strategy adopted, which is consistent with door to door sales and through agreements with commercial partners located in the neighborhoods where their clientele reside. Socially, there was a great deficit of urban rigging and public investments in the direction of adequately adapting to the local needs of the population: the access to health to be improved, ergonomically lacking works, optimization of the elements essential to urban mobility (in face of the neighborhoods of Capão Redondo and Grajaú) such as public transport and others. From the environmental point of view, the company under study innovated by being able to reduce the amount of carbon dioxide initially promoted in its regionally directed sales. The contributions to the presented practice showed that new strategies of approaching the company with the clientele can supply the demand of a sustainable way for the lesser part of the city. As contributions to the theory the research was shown to be relevant when presenting that the tripod of sustainability can be applied by companies in diverse segments, as exposed, the branch of hearing aids in peripheral regions of the city of São Paulo. It is also concluded that if the entrepreneurs intelligently apply their resources, beneficially will influence the quality of life of their clientele, even more positively enhancing their business as a whole. / A sustentabilidade das cidades passa pelo aspecto da logística relativo ao transporte de pessoas residentes em regiões periféricas dos grandes municípios e que carecem de atenção quanto ao acesso aos bens e serviços, sejam estes de caráter público ou de caráter privado. No caso particular dos idosos residentes distante do centro da cidade de São Paulo, é possível observar que passam pela dificuldade oriunda do próprio envelhecimento, a questão da temeridade em face da baixa segurança na área mais central da cidade, falta de opções de transporte público, distâncias alongadas pelo crescimento humano e inacessibilidade a serviços públicos e privados. Investigou-se a questão do idoso portador de problemas auditivos que carece de atendimento para adquirir aparelhos auditivos e a manutenção desses equipamentos. Por objetivo geral têm-se apresentar os elementos com base nos três pilares da sustentabilidade (Triple Bottom Line), que podem contribuir na melhoria da prestação de bens e serviços a idosos que utilizam aparelhos auditivos e residem em regiões periféricas da cidade de São Paulo. Metodologicamente optou-se pela investigação de abordagem mista: qualitativa e quantitativa e, ainda, baseada nas técnicas de revisão bibliográfica, análise documental e análise estatística a partir de levantamento em campo e aplicação de questionário estruturado. Por resultados, pôde-se encontrar que, do ponto de vista econômico, a empresa sob estudo proporcionou novas possibilidades e novos ganhos reais com a nova estratégia de vendas adotadas, esta consistente nas vendas door to door e por intermédio de acordos com parceiros comerciais localizados nos distritos em que sua clientela reside. Socialmente, apurou-se grande déficit de aparelhamento urbano e investimentos públicos na direção de se bem adequar às necessidades populacionais locais: é o caso do acesso à saúde a ser melhorado, calçamento ergonomicamente carente de obras, otimização dos elementos essenciais à mobilidade urbana (em face dos bairros do Capão Redondo e Grajaú), como o transporte público e outros. Do ponto de vista ambiental, a empresa estudada inovou ao conseguir diminuir o montante de gás carbônico inicialmente promovido em suas vendas regionalmente direcionadas. As contribuições para a prática apresentadas mostraram que novas estratégias de aproximação da empresa com a clientela podem suprir a demanda de uma forma sustentável para a parte menos abastada da cidade. Como contribuições para a teoria a pesquisa se mostrou relevante ao apresentar que o tripé da sustentabilidade pode ser aplicado por empresas em seguimentos diversos, como exposto, o ramo de aparelhos auditivos em regiões periféricas da cidade de São Paulo. Conclui-se, igualmente, que se o empresariado aplicar de modo inteligente seus recursos, beneficamente influenciará na qualidade de vida de sua clientela, potencializando, inclusive, de modo mais positivo, seus negócios como um todo.

Previous issue date: 2017-06-27 / Urban areas growth stimulates consumption and, consequently, industrial production. As a result, as the chemicals are consumed by almost all industries, their distribution flow is increasing in cities. By their nature, these products pose risks to society and the environment. Therefore, the intensification of the flow increases the society's exposure to such risks. In this scenario, risk management in the transportation of dangerous products is a topic of academic, public management and managerial concern. The objective of this research is to propose a framework for risk management in the transportation of dangerous products to contribute to urban mobility improvement. The method adopted began with the bibliometric and systematic literature review for the identification of risk factors, mitigation measures and response actions in the transport of dangerous products. These elements made up the theoretical framework analyzed empirically in three case studies of accidents in the transport of dangerous products occurred in the Metropolitan Region of São Paulo from 2006 to 2016. Cases were selected due to the repercussions of the accidents, the occurrence of victims and the availability of respondents. Data collection of multiple cases occurred through documentary research, semi-structured interviews and direct observation. The results showed that there is no linear correspondence between risk, mitigation and response: the elements organize themselves in the form of a broad range of risk factors that converges to a smaller and central group of possible incidents, which, again, diverge for a wider range of consequences. In this structure, there are actions that can prevent the risk factors from triggering the incident (mitigation actions) or that the incident unfolds into consequences (response actions). If the unfolding occurs and reaches the environment, remediation actions of impacts (resilience plan) are also necessary. The structure described was well represented by the bow-tie type tool. It was shown that the tool is suitable for risk management in transporting dangerous products. In addition, it was possible to conclude that: (i) for each risk there is at least one associated mitigation; (ii) for each incident, there are different possible responses, depending, in this case, on the accident characteristics; (iii) for inefficient responses, unfolding consequences may occur, requiring resilience measures (iv) there are transversal mitigation actions, such as the training and collection of transport information, that have the potential to mitigate diverse risks; (v) elements in the Brazilian scenario of dangerous products transportation, that were not yet reported in the literature, should be considered in the framework, such as public safety risk (and associated mitigation actions "use of intelligent traffic lights", "improvement of public safety", "use of cargo escort") and financial compensation as a resilience plan action. / O crescimento das áreas urbanas estimula o consumo e, consequentemente, a produção industrial. Com isso, por serem os produtos químicos consumidos por quase todas as indústrias, seu fluxo de distribuição vem aumentando nas cidades. Por natureza, esses produtos oferecem riscos à sociedade e ao meio ambiente. A intensificação do fluxo aumenta, portanto, a exposição da sociedade a tais riscos. Dessa maneira, a gestão de riscos no transporte de produtos perigosos é um tema de preocupação gerencial, de gestão pública e acadêmica. O objetivo desta pesquisa é propor framework para gestão de riscos no transporte de produtos perigosos para contribuir com a melhoria da mobilidade urbana. O método adotado iniciou-se com a revisão bibliométrica e sistemática da literatura para a identificação dos fatores de risco, ações de mitigação e ações de resposta no transporte de produtos perigosos. Esses elementos compuseram o framework teórico analisado empiricamente em três estudos de caso de acidentes no transporte de produtos perigosos ocorridos na Região Metropolitana de São Paulo entre os anos de 2006 e 2016. Os casos foram selecionados pela repercussão dos acidentes, pela ocorrência de vítimas e pela disponibilidade dos entrevistados. A coleta de dados dos múltiplos casos ocorreu por meio de pesquisa documental, entrevistas semiestruturadas e observação direta. Os resultados demonstraram que não há correspondência linear entre risco, mitigação e resposta: os elementos organizam-se sob a forma de um leque variado de fatores de risco que converge para um grupo menor e central de incidentes possíveis, que novamente diverge para um leque maior de consequências. Nessa estrutura, existem ações que podem evitar que os fatores de risco acionem o incidente (ações de mitigação) ou que o incidente se desdobre em consequências (ações de resposta). Caso os desdobramentos ocorram e atinjam o meio, são necessárias, ainda, ações de remediação dos impactos (plano de resiliência). A estrutura descrita mostrou-se bem representada pela ferramenta do tipo bow-tie. A ferramenta construída mostrou-se adequada para gestão de riscos no transporte de produtos perigosos. Ademais, foi possível concluir que: (i) para cada risco há, ao menos, uma mitigação associada; (ii) para cada incidente, há diferentes respostas possíveis, dependendo, neste caso, das características do acidente; (iii) para respostas ineficientes, desdobramentos poderão ocorrer, sendo necessárias medidas de resiliência; (iv) há ações de mitigação transversais, como o treinamento e levantamento de informações sobre o transporte que têm potencial de mitigar riscos diversos; (v) elementos no cenário brasileiro de transporte de produtos perigosos, ainda não relatados na literatura, devem ser considerado no framework, como o risco de segurança pública (e as ações de mitigação “uso de semáforos inteligentes”, “melhoria da segurança pública” e “uso de escolta de carga”) e compensações financeiras como ação do plano de resiliência.
