Proposta de rearranjo físico baseada no método ROC em uma confecção de pequeno porte

Abstract

This work is to apply the mathematical method Clustering Rank Order (ROC) to propose the development of cell production in the sewing sector of a small textile manufacture company and reduce the distances between the processes of the production system, including sewing through a physical rearrangement. The study started with conducting a literature review on the topics of lean production, manufacturing waste and physical arrangement. Since then, was identified six steps that comprise the study methodology, where after identified in the case study were applied to a company that belongs to the segment of the textile manufacture. As a result of applying the mathematical method was obtained in elaboration of four production cells, where each cell is linked to a product family, but found that due to the high degree of similarity existing among the manufactured products necessarily have to pass through more than one cell for transformation, characterizing the cellular layout proposed for the sewing process as a hybrid. Giving sequence to the case study, was proposed a rearrangement of existing production processes, where by using spaghetti diagrams could observe simplification of production flow and reducing the transport of material. It is concluded, therefore, that even the layout presenting cell hybrid character, for manufacturing waste reduction, the proposed formulating production cells, in this type of process is valid.
