Decentralized decision-making is an active research topic in artificial intelligence. In a distributed system, a number of individually acting agents coexist. If they strive to accomplish a common goal, the establishment of coordinated cooperation between the agents is of utmost importance. With this in mind, our focus is on multi-agent reinforcement learning (RL) methods which allow for automatically acquiring cooperative policies based solely on a specification of the desired joint behavior of the whole system.The decentralization of the control and observation of the system among independent agents, however, has a significant impact on problem complexity. Therefore, we address the intricacy of learning and acting in multi-agent systems by two complementary approaches.First, we identify a subclass of general decentralized decision-making problems that features regularities in the way the agents interact with one another. We show that the complexity of optimally solving a problem instance from this class is provably lower than solving a general one.Although a lower complexity class may be entered by sticking to certain subclasses of general multi-agent problems, the computational complexitymay be still so high that optimally solving it is infeasible. Hence, our second goal is to develop techniques capable of quickly obtaining approximate solutions in the vicinity of the optimum. To this end, we will develop and utilize various model-free reinforcement learning approaches.Many real-world applications are well-suited to be formulated in terms of spatially or functionally distributed entities. Job-shop scheduling represents one such application. We are going to interpret job-shop scheduling problems as distributed sequential decision-making problems, to employ the multi-agent RL algorithms we propose for solving such problems, and to evaluate the performance of our learning approaches in the scope of various established scheduling benchmark problems.

En la actualidad, se evidencia un incremento de residuos sólidos en Lima Metropolitana (INEI, 2019). Según el informe de INEI, los distritos que generan mayor cantidad de residuos son Santiago de Surco, Miraflores, San Miguel y La Molina. Por otro lado, la pandemia generada por el COVID-19 ha generado un cambio en los hábitos de compras del consumidor y esto se ve reflejado debido a que existe un incremento en las compras a través del e-commerce, con la finalidad de evitar los contagios los consumidores prefieren comprar todo tipo de artículos desde la comodidad de su hogar. Tomando en consideración ambas variables, nace la idea de crear un proyecto de florería ecoamigable con la modalidad de delivery. Para ello, se hará uso de productos eco-amigables los cuales permitirán reducir el consumo de plásticos y otros materiales dañinos para el medio ambiente comparado a los arreglos florales tradicionales ofrecidos en las florerías. De esta manera, se busca generar conciencia en los consumidores respecto a la importancia de cuidar el medio ambiente. Por lo tanto, se realizó una investigación cualitativa para determinar la frecuencia y aceptación de este proyecto en las zonas 6 y 7 de Lima Metropolitana. Además, se realizó un análisis financiero a través del cual se obtuvieron indicadores de rentabilidad favorables, los cuales avalan la viabilidad y rentabilidad de poner en marcha “Costumbres Latinas” un proyecto que ofrecerá la posibilidad de reducir la contaminación ambiental a través del uso de productos orgánicos y el reciclaje de residuos sólidos. / Currently, there is an increase in solid waste in Metropolitan Lima (INEI, 2019). According to the INEI report, the districts that generate the greatest amount of waste are Santiago de Surco, Miraflores, San Miguel and La Molina. On the other hand, the pandemic generated by COVID-19 has generated a change in consumer shopping habits and this is reflected due to the fact that there is an increase in purchases through e-commerce, in order to avoid contagions consumers, prefer to buy all kinds of items from the comfort of their home. Taking both variables into consideration, the idea of ​​creating an eco-friendly florist project with the delivery modality was born. For this, eco-friendly products will be used which will reduce the consumption of plastics and other materials that are harmful to the environment compared to the traditional flower arrangements offered in flower shops. In this way, it seeks to generate awareness in consumers regarding the importance of caring for the environment. Therefore, a qualitative investigation was carried out to determine the frequency and acceptance of this project in zones 6 and 7 of Metropolitan Lima. In addition, a financial analysis was carried out through which favorable profitability indicators were obtained, which endorse the viability and profitability of launching "Latin Customs" a project that will offer the possibility of reducing environmental pollution using products. organic and solid waste recycling. / Trabajo de investigación

En los últimos años se ha podido ver una tendencia al comercio de ropa de segunda mano en distintas partes del mundo, lo que se entiende como un modelo de negocio que se adapta a las necesidades de las personas de poner a la venta diversas prendas que probablemente tienen en desuso, por las cuales desean obtener un ingreso extra. Este es un tipo de negocio que nace a raíz de las diversas personas que no realizan un uso frecuente de sus prendas al adquirirlas, por distintas razones, y por ello deciden ponerlas en venta, dando apertura a la posible adquisición por parte de otras personas. Actualmente el mercado textil se encuentra en constante crecimiento a raíz de las tendencias de moda que vienen apareciendo continuamente lo cual permite desencadenar diversas formas de implementar negocios relacionados a ello que permiten a las personas ser partícipes del mismo de distintas maneras. Es por ello que nace Closet Out, una marca y modelo de negocio presentado bajo una plataforma web que permite interconectar a aquellas personas que deseen comprar o vender prendas de vestir de segunda mano y de alta calidad. / In recent years it has been possible to see a trend in the trade of second-hand clothing in different parts of the world, which is understood as a business model that adapts to the needs of people to put on sale various garments that probably they have in disuse, for which they want to obtain an extra income. This is a type of business that was born as a result of the various people who do not make frequent use of their garments when acquiring them, for different reasons, and for this reason they decide to put them up for sale, opening up the possible acquisition by other people. Currently the textile market is constantly growing as a result of the fashion trends that are continuously appearing which allows to unleash various ways of implementing related businesses that allow people to participate in it in different ways. That is why Closet Out was born, a brand and business model presented under a web platform that allows people who wish to buy or sell second-hand and high-quality clothing to interconnect. / Trabajo de investigación
