Diseño de una propuesta para el mejoramiento de la productividad en el área de pegamento en la planta de Evacol S.A.S

Abstract

The general objective of this study is to design a proposal to improve the production process in the area of glue in Evacol S.A.S based on the principles of the theory of restrictions that positively affect productivity. To fulfill this purpose, it was necessary to analyze the glue process, identify the bottleneck and analyze the efficiency index of the OEE industrial machinery. This study is descriptive, correlational and explanatory. It uses in its development tools of industrial engineering like: theory of restrictions, study of times, diagram of Ishikawa, OEE, and balancing of line; through which it was possible to identify that the problem is focused on efficiency, once the time study was done, two bottlenecks were identified within the process in the glue line. The first was the activity in which the operator inspects the correct pair and size of footwear and thermoplastic rubber (TPR) to the footwear. The second restriction was found in the operation to reactivate footwear, in order to increase the capacity of these restrictions, it was proposed in the first instance to carry out a line balancing in which the number of operators required for each task or operation was determined and activities were reassigned in the line, while for the operation of reactivating the footwear, it was proposed to carry it out as a pre-setup in which a product warehouse is included in the process so as to be able to count on the inventory required by the shift on the line. With these proposals the following results were reached. The efficiency increases from 50.42% to 89.63%; productivity from 50.8% to 89.1% and OEE from 45.89% to 83.13%. There were limitations in the execution of the project such as the coincidence of the manufacturing dates of the reference under study, change of production engineer, rotations in the work places by operators that did not allow to take normal times, business hours of the company, Saturdays of inventories, among others; who prolonged their execution; nevertheless, the information was obtained and the company contributed to its achievement.
