“…Real world experimental results were obtained with a robotized Kalmar Tugmaster truck ( Figure 12 and Figure 13 ), in the framework of the Autoport project [ 25 ]. Here, the robotized vehicle was autonomouslly driven on a Ro-Ro ship hold, whose map is shown in Figure 14 , as well as on a 9.5 m × 39.1 m narrow environment at a warehouse, which was also cluttered with several hydraulic jacks and other furniture.…”

This paper presents an algorithm for finding a solution to the problem of planning a feasible path for a slender autonomous mobile robot in a large and cluttered environment. The presented approach is based on performing a graph search on a kinodynamic-feasible lattice state space of high resolution; however, the technique is applicable to many search algorithms. With the purpose of allowing the algorithm to consider paths that take the robot through narrow passes and close to obstacles, high resolutions are used for the lattice space and the control set. This introduces new challenges because one of the most computationally expensive parts of path search based planning algorithms is calculating the cost of each one of the actions or steps that could potentially be part of the trajectory. The reason for this is that the evaluation of each one of these actions involves convolving the robot’s footprint with a portion of a local map to evaluate the possibility of a collision, an operation that grows exponentially as the resolution is increased. The novel approach presented here reduces the need for these convolutions by using a set of offline precomputed maps that are updated, by means of a partial convolution, as new information arrives from sensors or other sources. Not only does this improve run-time performance, but it also provides support for dynamic search in changing environments. A set of alternative fast convolution methods are also proposed, depending on whether the environment is cluttered with obstacles or not. Finally, we provide both theoretical and experimental results from different experiments and applications.

For decades, the technology of freight railcars has not changed significantly, mostly due to little or no incentive for significant investments in rolling stock. Taking into account the disruptive developments anticipated in automotive transportation, this approach appears no longer feasible, especially if regulatory agencies aim to reduce carbon dioxide emissions while maintaining economic growth. With the advent of telematics, on-board sensing and cloud-based analytics for control and condition based maintenance, high potential for efficiency improvements has become possible. Such technologies are de facto standards in automotive transport, which induces the need for implementation of similar technologies in rail transport as well. In addition to enabling efficiency gains, telematics, on-board sensing and cloud-based analytics also offer new means to approach pressing problems such as rail noise emission, train integrity and safety against derailment, while at the same time reducing maintenance cost and downtime. Furthermore, a connected wagon offers a seamless integration into current and future logistics systems, which are driven and controlled by the industrial Internet of Things to support the fourth industrial revolution. An important concept, introduced with theWagon 4.0, is standardized hardware, together with an open-source operating system based on prognostics and health management principles for predictive analytics. Thus, the Wagon 4.0 paves the way for new operations and maintenance concepts, user interfaces and value proposals. Additional economic advantages will be made possible from the self-organizing features of such vehicles, the ability to achieve mass customization and from a rise in efficiency in operation and maintenance. This paper describes the basis of such a system including the power supply, intra-train communications, sensing and cloud-based analytics. A study of use cases from railway operation illustrates the approach and highlights the opportunities of this novel system design. The paper concludes with a description of how the implantation enables the railcar operator to practice predictive maintenance and increase operational efficiency.

Fluvial transport of LPG into the state of Amazonas (Brazil) has been made precarious and artisanal over the years. The solution to this problem was the implementation of the system roll on -roll off to boarding canisters of LPG that are sent to the state. This paper presents the case study and the solution to the faced problem. The specific objectives, as well as the results from the implementation of this new mode of delivery of LPG cylinders for the interior of the Amazonas state, will be presented in this article. Keywords I INTRODUÇÃOA utilização do planejamento estratégico em uma organização é um processo que, quando bem implementado, mobiliza as empresas e seus colaboradores em busca de resultados de longo prazo. O Planejamento Estratégico através da metodologia Balanced Scorecard, possui quatro pilares fundamentais que são: pessoas, processos internos, clientes e finanças. Basicamente pessoas bem treinadas, qualificadas, motivadas, executam processos internos de forma eficiente, fazendo com que os clientes fiquem satisfeitos e consequentemente, a empresa tenha rentabilidade superior. Todos os colaboradores da organização precisam estar focados no planejamento e execução da estratégia da organização.O pilar processos internos, precisa estar em constante evolução, com inovações que tragam agilidade aos processos executados, tendo em vista que os clientes estão cada vez mais exigentes. O sistema de gestão, com a utilização de indicadores que apontem as oportunidades de melhoria, completa as etapas do planejamento organizacional.O processo de entregas para os Revendedores dos municípios que são acessados somente por via Fluvial no Amazonas, historicamente, sempre foi de elevado grau de complexidade. A análise dos indicadores relativo aos processos desta atividade, apontavam para um elevado índice de insatisfação por parte da rede de Revendedores, devido a demora para conclusão do desembarque de botijões vazios e embarque de botijões cheios, assim como custos elevados e riscos de acidentes, ergonômicos e físicos.O presente artigo trata da implantação do sistema roll on -roll off para o transporte de botijões de GLP para os municípios do estado do Amazonas que são acessados somente pelo modal de Transporte Fluvial.O transporte de botijões para estes municípios é realizado em balsas de diferentes portes, conforme demonstrado na figura.
