This research is carried out in a company that produces frames and moldings and addresses the need to develop a Total Productive Maintenance (TPM) program, as a result of the unavailability of machinery and equipment; and training that affects maintenance operations, which are not performed correctly causing costs. Currently there is a 76% availability of machinery; 78% in equipment; 42% in training and monthly average costs in machinery of $ 15,260 pesos; and in equipment of $ 1,860 pesos, in terms of maintenance costs there are no globales records. The objective was to carry out a proposal for maintenance activities, through the TPM methodology; to have an updated maintenance program. The procedure was: Describe the area under study; describe the situation of the area under study; establish TPM policies and goals; identify failures in machinery and equipment; and develop the maintenance program. It was contributed with the contribution of a maintenance program composed of: calendar, records of equipment in stock, corrective and preventive maintenance, maintenance scheduling, records of maintenance costs and catalog. Thus fulfilling the objective of this investigation.

This research is carried out in a company that manufactures inorganic fertilizers and addresses the need to acquire a sanitary license for the mixing and packaging of fertilizers. For this, it is required to comply with the regulatory requirements established by COFEPRIS and STPS in the area of industrial and toxic waste management with code (CRETIB) Corrosive, Reactive, Explosive, Toxic, Flammable, Infectious-Biological. Currently there is a 17% regulatory compliance representing a risk to the integrity of employees and the revision of the license. The objective was to carry out improvement actions through the guidelines established by COFEPRIS to increase the percentage of compliance with them. The procedure was: Describe the area under study, prepare a list of requirements, security measures, document with training and dissemination to workers, technical information card, inventory of raw materials, personal protective equipment and determine the compliance of requirements. Eight documents were delivered which were necessary to comply with the requirements established in compliance with the objective and increasing the percentage from 17% to 83% compliance.

The present project took place in a pork production company, which wants to reduce the waste of the products of the slicing area, specifically in the products Belly Slice, Kataroso Slice 120 gr and Belly Slice (3cm), aiming to identify activities that do not add value, through lean manufacturing tools, to propose improvement actions in the slicing process in the production area. The procedure used was to describe the activities of the process, generate specifications table of products, determine cycle time and productive capacity, determine sample size, prepare Value Stream Map (VSM) of the current process, identify activities that generate waste, perform VSM of the future situation and, finally, generate proposals for improvement. As a result, was obtained a program to monitor production, adapt the production line as a manufacturing cell and create a format for preventive maintenance of machinery and equipment; as well as the information that will lay the foundations for the products under study. With these actions, the intention is to contribute to the continuous improvement of performance, productivity and efficiency indicators.

El objetivo del presente estudio fue analizar el alto consumo de combustible de una flota de autobuses modelo volvo 9700. El desarrollo del proyecto implicó analizar el impacto de la variable denominada peso del equipaje en diferentes unidades del mismo modelo, mediante la metodología Lean Six Sigma la cual está comprobada que es útil para la solución de problemas sobre procesos ya creados. Los resultados del análisis mostraron como resultado que no existe relación significativa entre las características del equipaje y el consumo de combustible, por lo que no influye el peso del equipaje en el consumo de combustible; sin embargo, el conocimiento de dichas características puede ser de gran utilidad para la empresa, para emprender acciones que le permitan mejorar la gestión del equipaje en el área de carga de los autobuses.

This research analyzes a skewer production line of a meat processing company due to the fact that it presents bottlenecks and leisure time, with the objective of proposing improvements in the method through the analysis of operations. The procedure was to know the specifications of the product and the process, study the activities and determine standard times by the Maytag Company method. The results show that the critical operations are those of portioning and assembling the product for which three improvement proposals were designed whose evaluation determined that the mold method is the most suitable for the production of skewers. The chosen method is considered more efficient, since when compared to the current method, it presents a decrease in the operating time of 11.68s per product, as well as 7.88s in leisure time, resulting in an increase in production of 321.95 kg per shift, this represents an increase of 124.83% in the efficiency of the production line, making evident the relevance of these techniques for the continuous improvement of the processes.
