“…The results of the present study were similar to those of Tomazela et al (2010), who obtained 0.97 L t -1 and, although very close, were higher than those obtained by Lyra (2012), 0.71 L t -1 , Belardo (2010), 0.70 L t -1 , and Schmidt Júnior (2011), 0.75 L t -1 . Rosa (2013) observed that, due to the greater harvesting capacity for the machine harvesting in dual row spacing, the fuel consumption per harvested ton is lower, being virtually half compared with the results of studies using single row spacing.…”

A B S T R A C TThe interventions performed during the mechanized harvesting are essential to improve the operational performance of sugarcane harvesters and reduce operational costs. The objective of the present study was to evaluate the fuel consumption of a sugarcane harvester in different forward speeds and engine rotations. Harvesting was conducted in a green cane plot, with the variety RB 855156. Flow meters were installed in the harvester's fuel supply system and an electronic device was used for data acquisition. The experiment was carried out in a completely randomized design in a factorial scheme (3 x 2), using three engine rotations and two forward speeds, with six replicates. Harvesting capacity and fuel consumption per hour, per area and per ton of harvested sugarcane were analyzed. The results were subjected to analysis of variance and means were compared by Tukey test. The variations in engine rotation did not affect the performance for harvesting capacity, but influenced fuel consumption. Forward speed influenced both harvesting capacity and fuel consumption.Consumo de combustível de uma colhedora de cana-de-açúcar em diferentes configurações de operação R E S U M O As intervenções realizadas durante a colheita mecanizada são fundamentais para a melhoria do desempenho operacional das colhedoras de cana-de-açúcar e redução dos custos desta operação. O objetivo foi avaliar o consumo de combustível de uma colhedora de cana-deaçúcar em diferentes velocidades de trabalho e rotações do motor. A colheita foi realizada em canavial sem queima prévia cuja variedade foi a RB 855156. Foram instalados medidores de fluxo no sistema de alimentação de combustível da colhedora e utilizado equipamento eletrônico para aquisição dos dados. O experimento foi conduzido em delineamento inteiramente casualizado em arranjo fatorial 3 x 2 usando três rotações do motor e duas velocidades de trabalho, com seis repetições. Foram avaliados a capacidade de colheita e o consumo de combustível horário, por área e por tonelada colhida. Os resultados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey. As variações na rotação do motor não interferiram no desempenho para capacidade de colheita, porém influenciaram significativamente o consumo de combustível da colhedora; já a velocidade influenciou tanto a capacidade de colheita como o consumo de combustível.

“…In the agribusiness sector, in particular, the identified publications that depict the application of Lean Production System present, predominantly, exploratory and descriptive character. From these, the case study is the research method for (Barth et al, 2013;Cox et al, 2007;Perez et al, 2010;Silva, 2006;Simons & Zokaei, 2005;Taylor, 2006;Simons & Taylor, 2007;Tanco et al, 2013;Xie & Li, 2012) and the survey method for (Cardozo et al, 2011;Claire et al, 2014;Forrester et al, 2010;Tomazela et al, 2010).…”

“…Taking into account the approach aligned to designated research methods, studies aim at the implementation of the Lean Production System in parts of the process (Xie & Li, 2012), in the organization (Barth et al, 2013;Dora & Gellynck, 2015;Tanco et al, 2013), and in the supply chain (Cox et al, 2007;Perez et al, 2010;Simons & Taylor, 2007;Simons & Zokaei, 2005;Taylor, 2005Taylor, , 2006. Evaluation studies also occur on the use of Lean Production System in internal environments of the organization or along the chain (Claire et al, 2014;Dora et al, 2013;Forrester et al, 2010;Cardozo et al, 2011;Silva, 2006;Tomazela et al, 2010).…”

The literature regarding Lean Production philosophy is vast depicting historical aspects, implementation challenges, benefits of its adoption and other topics applied to various industries and services. However, the agribusiness segment, one of the major segments of the global economy features a large gap in national and international literature. This article aims to conduct a research through multiple case studies concerning the use of techniques and tools of Lean Production System in agribusiness organizations. Multiple type case studies were conducted in eight agribusiness units from different segments through the application of structured interviews, on site visits and document analysis. The research carried has identified that Lean Production techniques and tools are applicable to agribusiness environments, and that the ones which involve improvements in process control, production flow and logistics have higher emphasis on research units. Techniques and tools such as long-term supplier and customer relationship, production smoothing/heijunka and value stream mapping distinguished themselves by the similarity of use when compared to previous studies in agribusiness environment. It was also identified that there are differences concerning the adoption of the techniques and tools in research units that operate in production environments of the type Make to Order or Make to Stock. Such differences are imposed by specificities that affect agribusiness organizations, which is indicative for future studies.
