In the current competitive and global scenario, companies in search for solutions that become the production every time more efficient is increasing and at the same time cost reductions and cost eliminations are becoming increasingly evident and needed. In an attempt to improve production, this work aims to compare benefits obtained using principles of philosophy Lean Manufacturing in an productivity growth of a cell from an auto parts sector industry. For that purpose it will be studied the history, the concepts and the tools of philosophy Lean Manufacturing, thus using the as a business-strategic tool to accomplish goals that the company expects to get greater competitiveness and quality. The efficiency of philosophy Lean Manufacturing was already confirmed through applying the concepts in the process which has been improved inside an auto parts sector industry. At last, comparative analyzes showed benefits obtained with the use of Lean Manufacture tool called VSM, Value Stream Map, which translates the Value Stream Map of a particular family of parts as the identification, minimization and elimination of waste identified

The use and inadequate exploitation of natural resources is restricting the occurrence of aroeira (Myracrodruon urundeuva F.F. & M.F. Allemão), which now is on the FAO list of endangered species. This exploitation causes a decrease in the genetic base of M. urundeuva populations, which makes it difficult to find genotypes with stability and adaptability to different growing conditions. This study aimed at estimating the genetic variation and productivity, stability and adaptability of progenies of a M. urundeuva natural population, from the Ecological Station of Paulo de Faria-SP, under different planting systems. DBH (diameter at breast height) was evaluated in four progeny tests of M. urundeuva: i) planted with Anandenanthera falcata and Guazuma ulmifolia (TP-AMA); ii) single (TP-ASO); iii) planted with annual crops (TP-SAF) and iv) planted with Corymbia citriodora (TP-EUCA), installed in Selvíria-MS. The experimental design consisted of complete randomized blocks with three replications and a variable number of plants per plot in each of the four planting systems. From the joint analysis of the planting systems studied, it was found that: i) there were variations among planting systems particularly in TP-SAF; ii) only in TP-EUCA it was possible to detect variations among the progenies; iii) the effects of the genotype x environment interaction were not significant. Thereby, the harmonic mean of genotypic values (MHVG), the relative performance of genotypic values from the mean of each site (PRVG) and the harmonic mean of the relative performance of genotypic values (MHPRVG) for DBH showed, respectively: progenies with greater stability, adaptability, and stability and simultaneous adaptability within different planting systems. The use of these selection criteria provided a more refined selection of the best progenies of M. urundeuva under the different planting systems studied.
