Multimodal logistic platforms structure analysis worldwide: a comparative study between Brazilian and foreign projects

Plataformas logísticas multimodais - MLPs - fornecem integração de diferentes modos de transporte, possibilitando flexibilidade no sistema logístico e gerando vantagens competitivas. Buscando destacar as características de que uma MLP deve atender às necessidades do mercado, este estudo teve como objetivo uma análise comparativa entre as estruturas MLP que operam na Europa, Ásia e América do Norte e dois projetos brasileiros avançados. Portanto, apresentamos uma comparação com base em variáveis como a natureza do modal, sistema de gerenciamento, área residencial e tipos de carga manipulados. Os resultados sustentam que os projetos brasileiros são semelhantes aos MLPs internacionais e podem atingir o mesmo nível de competitividade

Maketo- stock production systems need to reduce stocks in order to enhance the performance of their productive processes. However, the application of CONWIP is sparse in MTS systems industrial reality. Hence a research has been done, through computational simulations and modelling methodology, with the aim to compare the operational results of a real productive MTS system with the results that a CONWIP method managed system would generate. The CONWIP hás held the demand by reducing the excess production presented by MTS, using 71% less inputs and reducing the processing stocks (WIP) by 85%. Considering the Factory Physics laws, the CONWIP performance was better when compared to MTS for enhancing the resources usage, reducing the processing time variability and eliminating the waste. This work hás contributed to reduce CONWIP performance analysis through computational simulation and modelling studies absence in literature.O método de gerenciamento da produção CONWIP sobresai em sistemas produtivos jobbing por eliminar desperdícios e aprimorar o desempenho do processo produtivo. Sistemas de produção make-to-stock (MTS) necessitam reduzir estoques de modo a aprimorar o desempenho de seus processos produtivos. Entretanto a aplicação do CONWIP é escassa na realidade industrial de sistemas MTS. Nesse contexto foi realizada uma pesquisa, através da metodologia de modelagem e simulação computacional, com o objetivo de comparar os resultados operacionais de um sistema produtivo MTS real com os resultados que geraria ao ser gerenciado pelo método CONWIP. O CONWIP atendeu a demanda reduzindo a produção em excesso apresentada pelo MTS, utilizando 71% menos insumos e reduzindo o nível de estoques em processo (WIP) em 85%. Considerando as leis da Ciência da Fábrica o desempenho do CONWIP foi melhor, comparado ao MTS por ter aprimorado a utilização dos recursos, reduzido a variabilidade dos tempos de processamento e eliminado desperdícios. Este trabalho contribuiu para diminuir a ausência de estudos na literatura com análises do desempenho do CONWIP através da modelagem e simulação computacional

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
