Redução de reprocessos em uma indústria de milho através da utilização de ferramentas da metodologia 6 sigma

Abstract

The objective of this work is to reduce the reprocess in a corn seed industry due excess of physical defects at the final product. Most of the defective seeds are rotten grains, which, due to the difficulty of their removal in the process, cause great impacts on the capacity and yield of the plant. 6 Sigma methodology was used to find root causes through in-depth statistical analysis and to define the actions necessary to mitigate the problem. All the work was structured in the DMAIC cycle and was developed with the aid of statistical analysis and quality tools, such as Pareto Diagram, Ishikawa Diagram, Capability Analysis, etc. From the analysis of all the hypotheses raised, it was possible to implement effective actions that obtained a much greater gain than initially proposed at the project.
