This paper aims to demonstrate how the adoption of a continuous improvement program, based on lean manufacturing tools, can benefit the production of automotive filters for heavy vehicles, considering improved productivity and reduced operational waste, with a consequent increase in effectiveness and cost reduction. In this study we used the lean manufacturing tools, mainly kaizen and value stream mapping. During its development, the application of a kaizen project in a production line of automotive filters for heavy vehicles, aimed obtaining increased productivity and better distribution of physical space, through the reduction of rework time, reduction of downtime due to maintenance and reduction of setup time. The use of lean manufacturing tools, through the instruments presented in this study, guaranteed the viability of improvements in the productive sector. This work allowed the observation of a consistent improvement in production capacity, with productivity increase, through the improvement of the operational time and reduction of time of waste. The best distribution of physical space and the best arrangement of items used by the production process were also achieved through the consolidation of two production lines.
The present study refers to the statistical analyzes applied to the production of commercial eggs carried out in a Poultry Company in the interior of the State of São Paulo, Brazil. Currently, the concern with consumer demands is growing in the food sector, which makes companies seek to increase the level of quality of their products. In this study, the application of statistical analysis was applied to the data obtained from the software that integrates a crack detection accessory, the Crack Detector of 12 egg production lines for 6 months. It was concluded that, when performing the nonparametric tests, Spearman and Kruskal tests, the data are correlated and there is a difference between the analyzed cracks among the quality control equipments. As result of this research work a calibration plan for the measurement equipments was suggested, in order to increase the reliability in the quality control inspection process, reducing the amount of non-conform products delivered to the customers market.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
