Teoría de Restricciones en el área de producción en industrias textiles para el incremento de la productividad

Abstract

The research project deals with the implementation of the theory of restrictions in the production area in textile industries to increase productivity. The investigation started from the analysis of the current situation of the company, for this information was requested from the commercial department regarding the sales made in the months of February, March and April 2021, with these data the Pareto analysis was carried out to determine the 20% of products that represent 80% of the demand, obtaining a total of 27 references with the highest demand. In order to obtain better results, an ABC classification was applied to these 27 references according to their demand, where it was determined that the references made in the production plant with the highest demand are 7; These references were unified in a single group (group 1), since they have the same pattern and processes in common. For group 1 of references, the process flow, analytical course chart was prepared, time was taken to establish the production standard and the units produced per day with a group of 14 people, finally the current productivity calculation was carried out, giving a value of 16.38 hour for units. Following the steps of the TOC methodology, the improvements were proposed, eliminating the restrictions, establishing the model to simulate considering four input variables: 1 production process, 2 arrival of cut and elastic, 3 start of each process and 4 standard time, and also four output variables: 1 throughput, 2 WIP, 3 productivity and 4 use of the process. The improvements are modeled using TOC, the simulation model is designed in Flexim, obtaining as a result of the simulation a productivity of 20.81 hour for units, with an improvement of 79% in relation to the current model.
