Lean manufacturing production management model to increase the efficiency of the production process of a MSME company in the chemical sector

In recent decades, the demand for a wide variety of products, lead to the requirement of having a reduced cost of manufacturing, shorter cycle times and perfect quality; forcing companies to implement different engineering techniques to have the best manufacturing system. With which it seeks to efficiently control the process, provide an optimal area of work, establish performance standards with respect to the operations that the company performs, thus generating better results in the organization to achieve higher levels of user satisfaction. In the case of the study, the main line of production in the company was analyzed, detecting that representative costs originated from reprocessing and downtime. The result of greater impact obtained was the reduction of the problems in one (60%) and (15%) respectively. In this way, it is expected that companies in the paint industry or products related to the sector can use the results obtained as a reference in their process of continuous improvement, improving the management and performance of the organization and customer satisfaction

Design and development of a model to improve the efficiency of the production process of a MYPE company dedicated to the production of industrial paints applying 5s, Work Study and Process Management

El presente proyecto de investigación se encuentra estructurado en cuatro capítulos los cuales son: Marco teórico y estado del arte, descripción y análisis del proceso actual, propuesta de mejora, validación de la propuesta de mejora, además de conclusiones y recomendaciones. La presente investigación está enfocada en la elaboración de un modelo de gestión la producción para la empresa Pinturas Tricolor Pintri S.A.C, la cual se dedica a la producción y comercialización de pinturas, con una demanda anual promedio de 108130 galones, siendo su producto patrón el “esmalte anticorrosivo”. El objetivo principal de la presente investigación es elaborar la propuesta de un plan de mejoras basadas en la filosofía de manufactura esbelta, para incrementar la eficiencia productiva de la empresa, que actualmente se encuentra en 66.50% situándose por debajo del promedio del sector químico que tiene un valor de 71.70%. Es por ello que se propone la implementación de las técnicas de estudio del trabajo, 5s y gestión por procesos con el objetivo de reducir tiempos muertos y reprocesos involucrados en la producción, siendo estos los principales causantes del problema. Entre los resultados de esta investigación se encuentra una reducción del 58.70% en reprocesos y una disminución del tiempo total de 0.97 h⁄cil a 0.82 h⁄cil, además, se logró incrementar a 81.51% la eficiencia actual del proceso de la empresa. La inversión para la implementación, tiene un periodo de recuperación equivalente a un 4.15 bimestres, siendo este viable, en donde se recupera la inversión y se obtienen ganancias.This research project is structured in four chapters which are: Theoretical framework and state of the art, description and analysis of the current process, improvement proposal, validation of the improvement proposal, as well as conclusions and recommendations. The present investigation is focused on the elaboration of a production management model for the company Pinturas Tricolor Pintri SAC, which is dedicated to the production and commercialization of paints, with an average annual demand of 108,130 gallons, its standard product being “ anticorrosive enamel ”. The main objective of this research is to develop a proposal for an improvement plan based on the philosophy of lean manufacturing, to increase the productive efficiency of the company, which is currently at 66.50%, being below the average of the chemical sector that has a value of 71.70%. That is why the implementation of work study techniques, 5s and process management is proposed in order to reduce downtime and rework involved in production, these being the main causes of the problem. Among the results of this research is a reduction of 58.70% in reprocesses and a decrease in total time from 0.97 h⁄cil to 0.82 h⁄cil, in addition, it was possible to increase the current efficiency of the company's process to 81.51%. The investment for the implementation has a recovery period equivalent to 4.15 two-month periods, this being viable, where the investment is recovered and profits are obtained.Trabajo de Suficiencia Profesiona

Abstract 1122‐000227: Stenting Versus Medical Treatment for Chronic Internal Carotid Artery Occlusions: A Systematic Review and Meta‐analysis

Introduction: Chronic internal carotid occlusion is responsible for 10–15% ischemic strokes or transit ischemic attacks (TIA). Subsequent ipsilateral ischemic stroke rate is 5.9% per year. However, this risk can increase up to 23% in two years in a subgroup of patients with poor collaterals regardless of medical therapy with antiplatelet or anticoagulant agents. Prevention of subsequent stroke in patients with carotid artery occlusion remains a difficult challenge. Carotid artery stenting (CAS) has recently been considered in its management. However, there is ambiguity on its safety. We aim to evaluate the safety and feasibility of CAS and compared it with medical management. Methods: We performed a systematic review and meta‐analysis to compare long‐term outcome (stroke recurrence) of current carotid occlusion treatments (CAS vs medical therapy). Two independent reviewers performed the screening, data extraction, and quality assessment. A random effects model was used for analysis. Results: A total of 5720 studies were screened. Of these, 11 studies were included in our systematic review and meta‐analysis of proportions. The CAS group has lower proportions of recurrent strokes (5% vs 30%,) after 30 days than medical therapy alone. Additionally, the proportion of periprocedural intracranial hemorrhage was 4.4% (95% CI 2.5 to 6.8) in the CAS group. Conclusions: CAS of the chronically occluded cervical ICA seems to be a safe procedure with lower rates of recurrent stroke in clinical follow up. Future randomized studies are warranted to guide the optimal management of this complex disease
