El presente trabajo tuvo como finalidad mejorar la calidad de servicio que tiene la empresa AVICESAR S.A.C, debido a que en su diagnóstico inicial se pudo destacar una diminución en sus ventas los últimos meses. Como indicador de calidad se consideró el índice de quejas con la que la empresa contaba, contabilizándose 188 quejas en 60 días, obteniéndose de esta forma el índice de 3,13 quejas por jornada laboral. Con el propósito de reducir este índice, se empleó la metodología de mejora SIX SIGMA. Esta metodología permite, mediante una secuencia ordenada de actividades (DMAIC), atacar la fuente que genera la variación en el producto final; para el caso del presente estudio, se recolectó datos de las quejas de los clientes durante dos meses, para luego buscar y analizar las causas que generan las quejas que tiene mayor incidencia y posteriormente, determinar soluciones que ...

The text examines the evolution of human nutrition from the emergence of the first hominids to the present day, focusing on how changes in food production have impacted both health and the environment. The objective of the research was to analyze these changes, emphasizing the responsibility of food companies in promoting sustainable and healthy practices. The methodology employed was a literature review, selecting 47 relevant articles published between 2016 and 2024. The findings revealed that although technological advances in food production have improved food security, they have also contributed to the rise in chronic diseases such as obesity and type 2 diabetes. Notably, the negative impact of consuming ultra-processed foods and refined grains was highlighted, along with the influence of marketing on dietary decisions. The study concluded that it is essential to reassess current pro...

The Peruvian diet is recognized worldwide for its diversity and exquisiteness, which has made it an international gastronomic benchmark. Proof of this is that Peru is home to some of the best restaurants in the world, with distinctions in prestigious guides such as The World's 50 Best Restaurants and Michelin stars. But this comes at a price, since its composition is dominated by foods rich in carbohydrates and processed, which negatively affects the health of the population. This study has set itself the challenge of analyzing how nutrients interact in the daily Peruvian diet and their effect on health. To this end, a literature review was carried out with studies published between 2014 and 2024, using academic databases and rigorous selection criteria. The results show that positive interactions, such as the combination of vitamin C with non-heme iron, improve the bioavailability of ke...

In this study, the aim was to reduce the distribution costs in an aquaculture company, which, after an initial assessment, were found to be excessively high with an uncontrolled statistical distribution. The initial approach focused on distribution costs per service provided, employing the DMAIC methodology as the primary improvement tool. This technique aided in breaking down effects and symptoms to identify the root causes of the issues, enabling the suggestion and implementation of improvements such as standardization of the order handling process, enhancement of communication channels, innovative recruitment strategies, and theoretical and practical training. These measures significantly improved the work environment, involving a more committed team and processes that were clearly established and aligned with the company's needs. Regarding distribution costs, there was a reduction fr...

The growing global demand for meat has generated a profound environmental, economic and social crisis. Where intensive production, slaughter and distribution generate a great environmental impact, due to the high water footprint, deforestation and greenhouse gas (GHG) emissions that contribute to the loss of biodiversity. The objective of this review is to analyze the challenges and possible solutions for a sustainable future in the meat industry, highlighting the urgency of moving towards more responsible food systems, due to the fact that 1.85 kg of CO2 fluctuates per kilogram of meat and its consumption also produces 84% hepatocellular carcinoma. On the other hand, agroecological practices are explored such as efficient manure management, the use of biodigesters to generate renewable energy, composting for the inactivation of pathogens in poultry waste, and the use of black soldier fl...
