Balanceamento de linha de montagem: calçados com imprecisão da demanda

Abstract

Line balancing aims to optimize and synchronize the processing of a product in order to meet the demand in the expected quantity and timeframe. In an assembly cell for footwear, a demand of 420 pairs per day was observed against a cell capacity of 815 pairs per day, resulting in a production process efficiency of 45.3%. Many companies apply line balancing techniques to increase the efficiency of their processes, which is the subject of this research. Based on a case study, a balancing study was developed for an assembly cell in a footwear company, where the resizing of the assembly cell capacity was done using OBC aiming to align the assembly line capacity with the proposed footwear demand. After confirming that the proposed balancing enabled better results, it was validated, presented, and implemented in the production process. With the implementation of the new OBC the efficiency jumped to 61.6%, representing a gain of 16.3%. As a result, the improvement generated estimated annual gains of approximately R$ 197,362.
