Any process of continuous improvement must promote that working conditions are presented in such a way that delays, operational losses or any failure are gradually reduced, so that the use of resources is as close as possible to the optimum. For this reason, it has been established as the primary objective in this study to determine a lean implementation proposal, through the use of lean production and process reliability tools, so as to promote the pursuit of mutual benefit in the use of opportunities for resources and processes improvement and optimization. Thus, measurements of the current system were made versus the proposed or improved one, in order to facilitate the operation, the work routines management, the facilities physical environment and the motivation growth of the whole staff in the company. This type of research is presented in a descriptive way, based on the Lean Manufacturing tools such as the five “S”s (5 s) and reliability maintenance tools through their concepts and the use of Weibull ++ 6 software.

The objective of this paper is to study the costs of non-quality in SMEs (Small and Medium Enterprises) in Colombia since they are the negative points of view of quality as they are associated with inefficiencies not avoidable at a certain time in the organization. Identifying these costs is difficult for SMEs, so they must be properly monitored in order to make the right decisions to obtain economic and commercial results that actively benefit the company and thus avoid and/or at least reduce these types of expenses. This research is based on a documentary methodology, a detailed bibliographic review is carried out to analyze the risks and characteristics associated with the non-quality costs – with this the study is approached. The materials used are documents with similar information that can be analyzed to obtain logical results, data were taken from institutional and reliable websites, minimizing the possibility of plagiarism, these are quantitative and the findings of the researchers are taken to facilitate interpretation. With the data collected, a study was carried out to determine the risks that commonly occur due to non-quality costs, and a plan can also be structured to carry out the control aiming at appropriate reducing outflows. The economy is becoming more and more complex worldwide, so strategies that are competitive in business improvements must be taken into consideration. Among the results obtained, it was learned that cost accounting allows interested parties to read the situation of the organization in monetary terms, with this information it is possible to recognize the usefulness that has been given to the resources, and it was also learned that not only what is associated with quality is taken into account, but also non-quality.

La presente investigación analiza la gestión de abastecimiento e inventario en la cadena de suministro del sector lácteo en Colombia, con particular énfasis en la región del caribe colombiano. Este sector se encuentra altamente influenciado por los fenómenos y cambios climáticos, tales como las estaciones, sequías e incluso movilizaciones sociales, los cuales inciden negativamente en el flujo continuo o normal de la cadena de abastecimiento (proveedor – transformador – minorista), logrando afectar el cumplimiento de los requerimientos de los clientes. Por ello, se presenta un modelo de optimización que considera las variables mas importantes del sistema, los parámetros identificados y las restricciones que detallan el comportamiento de la cadena. Finalmente, se proponen escenarios de mejora.
