Integration of Quick Response Manufacturing and Lean Manufacturing to increase on-time deliveries in a metal-mechanical company

Nowadays, companies sustain their permanence in the market with the satisfaction of their customers, and manufacturing companies, specifically those in the metal-mechanic sector, are no strangers to this. This is due to the fact that they have a method of working to order and a high variability of products with low volume, which leads to failure to meet delivery deadlines. Thus, in the field of industrial engineering, there is a percentage indicator that measures this problem. This is the "On Time Delivery" indicator which, with the efforts reviewed in the literature and success cases, is the most accurate for the analysis. The importance of solving this problem lies in the shortcomings of the models applied without a combined structure such as Quick Response Manufacturing and Lean Manufacturing. In this case study, a current value of 50.10% in orders with on-time delivery of the machining line was determined. This integrated model, post-validation, managed to increase the percentage of on-time deliveries to a final value of 91.07% (includes: final machine availability of 90.17%; Set-up time of 213.35 minutes and Cpk of 1.1651).
