Abstract

The objective of this research was to improve productivity in the production line of soles of Multisuelas Beltrán company from Ambato city, by applying tools of the Lean Manufacturing methodology, combined with the implementation of the PH VA Cycle. A diagnosis of the initial situation was done where the factors that affect the production process were made evident, to counteract the problem a continuous improvement plan was designed based on the PHVA cycle, and through a time study, movements and diagrams that allowed to identify the process, with the help of the VSM tool the opportunities for improvement were identified with the Kaizen bursts, Later, with the application of Kaizen and 9S check sheets, the percentage of Lean compliance was established, and with the calculation of the performance evaluation , the development of SMED of a proposal to decrease the preparation time was proposed , with the assistance of FM EA, the RCM plan was implemented , which reduced the failures in the injection molding machines. With the execution of the action plan, a comparative analysis of the initial situation was developed and after the application of the strategies it was determined that with the implementation the percentage of compliance with the 9S methodology was increased by 25%, Kaizen by 45%, with SMED the mold change was reduced by 8.81 minutes, productivity improved by 8.46% increasing the capacity of the i njection molding machines. It is considered that with the application of the PHVA cycle in com bination with the Lean Manufacturing tools, the objective of increasing the company's productivity was achieved. It is recommended that the company to engage in the process of constant improvement by evaluating the problems in order to ensure that the results remain the right way forward.
