Lean Process Optimization Model for Improving Processing Times and Increasing Service Levels Using a Deming Approach in a Fishing Net Textile Company

Over the years, the textile industry has become increasingly important, both domestically and internationally, owing to its great contribution to the economy. Therefore, with prior planning of resources and times, companies now need to increase each of their processes' efficiency to achieve the maximum potential in the shortest period of time. Based on this, order processing times become more relevant because they are critical for fulfilling this objective. Companies want to prevent cost overruns and sanctions. Therefore, they seek to implement improvements that may provide greater sustainability and reliability to both their production processes and end customers. For these reasons, this study proposes the application of Lean tools such as SMED, Kanban, 5S, and standardization based on the Deming Continuous Improvement approach. The main objective is to increase On Time In Full (OTIF) service levels from 56% to 63% by increasing the number of orders delivered on time. The case study is conducted in a fishing net textile company. This study is motivated by the lack of in-depth studies executed in this significant subsector, which exhibits a great development potential.
