Analizar y comparar la gestión de inventarios de materia prima clásica, versus el modelo (s, Q), con demanda y nivel de servicio definido, para la industria metalmecánica. Caso: “Metalmecánicos del Ecuador”.
Narváez Lara, Jean Pierre
This research work had the goal of analyzing and comparing two inventory management models applied at “Metalmecánicos del Ecuador”, a metal-mechanic company where the current model will be contrasted with a new proposal. The data will be collected at the organization with the goal of identifying opportunities for financial improvement and reducing inventory management costs, since opportunities to boost the company´s profitability have been identified. The metal-mechanic sector in Ecuador has been affected by constant variations in Steel prices, its main raw material, since Price fluctuations depend on the international stock market and thus do not allow Ecuadorian companies to have continuous and controlled resupply due to the uncertainty generated by variable prices. This study used the assessed company, which is part of one of the country´s most important strategic sectors, to test a controlled resupply model in which the demand is known and the level of service required by the company is defined prior to inventory management. After assessing both models, we will conduct an analysis of the costs generated by each one of them, comparing them and verifying which option generates the best results in this economic sector.

Estudio sobre el síndrome de Burnout en docentes de la Escuela Politécnica Nacional
Manzano Orbe, Luis André
This Master’s research focuses on why academic teaching staff at the National Polytechnic University (EPN) are experiencing and living with the various debilitating symptoms of Burnout Syndrome and identifying the main sources of stress that has caused the mental, emotional and physical exhaustion termed ‘Burnout’. In order to measure the ‘level of Burnout’ and the most likely causes of stress amongst academic teaching staff in their particular work environment, which includes the scope and nature of their individual functions, two questionnaires, already validated by previous studies, were used as the primary information gathering tools of this study. According to the results of this study, 10,71% of all full-time academic teaching staff at the National Polytechnic University (EPN) are showing clear symptoms of ‘Burnout’ and that the most common causes of this stress are; the lack of co-operation the lack of communication and constantly adapting to change. However, the study also shows that academic teaching staff find a lack of co-operation and a lack of communication more stressful than dealing with constantly adapting to change, which implies that they have developed ways of coping with ‘constantly adapting to change’. The results also indicate that there are no significant differences in the prevalence, magnitude and common causes of ‘Burnout’ neither between the different genders nor between the various faculties at the university.

Diagnostico de la gestión y el manejo de residuos líquidos químicos generados en las operaciones de docencia e investigación en los laboratorios de la Facultad de Ingeniería Química y Agroindustria de la Escuela Politécnica Nacional
Jácome Camacho, Gonzalo Rafael
This research reviews a management`s diagnosis and chemical liquid waste management generated during teaching and research operations in four departments from Chemical and agroindustry Engineering schools at Escuela Politécnica Nacional. It has the purpose of establishing a baseline to contribute to the development of a sustainable campus model, through a descriptive study supported by quantitative and qualitative information obtained from primary sources and secondary as well as field data, documentary review, interviews and reported statistics 1192,4 liters of liquid chemical waste was identified and classified, the ones which were stored in 738 containers, with a weight approximately 1240,3 kg of which 45% are special waste and mostly complex mixtures derived from research and educational practices, 32% correspond to organic and inorganic aqueous dilutions. It was determined that the packaging is not suitable for containing such substances. No labels were evidenced with regulatory information and the designated spaces for storage do not have the necessary conditions of ventilation, luminosity, mobility and accessibility, described by the Ministerial agreement 061 and standard INEN 2266. The complexity level with these regulations in the FIQA does not exceed 10%, in terms of internal institutional regulation. Therefore, it´s considered non-existent, in consequence, it establishes guidelines for these fundamental parameters in the chemical waste handling and management.

Análisis de la eficiencia de una red de transporte urbano terrestre público, mediante la utilización de un software especializado acorde al inicio de operaciones del metro de Quito en el centro histórico.
Cortez Chulde, Lenin Patricio
This work is a study to analyze the efficiency of a public terrestrial urban transport network, from the validation of the current conditions of the routes and the analysis of the available critical variables that influence the operation. Established this context, the use of a software that analyzes the efficiency of the routes and provides a framework of analysis of the variables to optimize is posed. Selects the route with greater inefficiency and routes that are in the vicinity to the new stops of the Metro of Quito in the downtown to generate new routes based on criteria of accessibility of stops and optimization of shortest path. After generating the new routes through specialized free software, the efficiency of the set of routes is again evaluated to compare with the initial scenario. It should be noted that due to the transversal configuration and the restricted pathway options in the historical center, the shortest path optimization is very limited and usually the algorithm produced similar results for different routes, on the other hand, at the end of the routes, it is possible to generate routes optimized by the availability of roads.

Análisis del costo beneficio de la implementación de procesos productivos automatizados para la eliminación de inspecciones redundantes de las empresas autopartistas. Caso: Transejes Ecuador Cía. Ltda.
Lalvay Espinosa, Alejandro Daniel
This Master's thesis intends to evaluate the feasibility of making the investment in the repowering of the productive processes considered critical within an Ecuadorian company of the auto parts sector. The decision to invest in this type of projects must have a very thorough analysis because automotive companies have very demanding quality standards to be able to manufacture their products, which leads to highly specialized production processes, to the point that they are unique in the manufacturing field. For the analysis will be taken into account the ease of access to the technology needed for the improvements identified in a previous quantitative analysis, also the investment needed to make such improvement and finally the social impact that these improvements may have on workers in this sector. The quantitative analysis will be carried out under the automotive standard IATF 16949:2016, in its section related to Statistical Process Control (SPC). This standard is under the approval of the Automotive Industry Action Group (AIAG), which is the largest association of automotive assemblers in the world where companies such as Ford, General Motors and Chrysler stand out.

Análisis del proceso de comercialización en el mercado Iñaquito: principales actores y dinámica
Chavarrea Centeno, Carlos Marcelo
This Master's thesis analyzes social composition in the Iñaquito market (La Carolina).The popular markets from its creation to the present dynamize the economy of the city and facilitate access to any kind of consumer considering non-discriminatory places that promote interpersonal communication between its actors.
This research has a non-experimental descriptive approach since it is based on the observation of demographic variables through its main actors (traders, consumers and suppliers
The study was done in 2019 with structured questions so were applied to both merchants and consumers that allowed us to characterize these actors and identify the main motivations of consumers.
In merchants, 78.7% of females predominate, most of them aged between 40 and 72 years, evidencing the absence of young traders who currently do not find this type of profession attractive. Income levels are relatively variable according to each section, clearly identifying enhanced and non-powered sections.
Consumers predominate in the male sex 62.9%, relatively young age 20 to 45 years whose income exceeding 1000 dollars 61%, have a level of education of third and fourth level, also identified factors such as hygiene, safety, quality and access to parking lots that encourage consumption in this market.
This study allowed us to make a diagnosis of the current market situation, which will be a reference for the management and implementation of improvements in the market.

Determinación del nivel de innovación dentro del sector metalmecánico aplicando un modelo de evaluación de capacidades, resultados e impactos. Caso de estudio: SEDEMI S.C.C.
Guayta Valladares, Nelson Eduardo
Innovation is considered a business development factor; therefore, the continuous improvement of innovation activities is the key to success. Innovation conduces companies to enhance their performance and, in this way, it makes companies more competitive improving at the same time living standards. Nowadays, there are not evidence about quantification of the innovation level in the Ecuadorian metalworking industrial sector. However, this is a relevant productive sector, so it is important to know its innovation level. The aim of this research is to estimate the innovation level in the company SEDEMI S.C.C., which is a representative company of the metalworking industrial sector of Ecuador. For that a model that analyze capabilities, results and impacts of innovation in the organization has been applied in order to estimate its innovation level; for the model application, two dimensions (implementation and importance) have been considered. Data has been collected through a questionnaire that evaluates the capabilities, results and impacts of innovation in the organization. Then, there was applied a principal component analysis in order to find the factors that better represent these three aspects (capabilities, results and impacts of innovation). Subsequently, the results obtained were compared with a baseline generated in previous researches. The results show that SEDEMI has an innovation behavior similar to the innovation behavior observed in other organizations of its regional business environment. Moreover, it is important to note that SEDEMI business model is focused on the satisfaction of client needs, then, its innovation objectives usually consider this approach. Finally, the existence of innovations in SEDEMI is observed, but there is not improved any formal procedures to promote and record the realize innovations, for this reason usually innovations are not visualized.

Análisis de la influencia de la implementación de un sistema integrado de transporte y el metro, frente al uso de vehículos particulares hacia el hipercentro del DMQ desde los valles
Paucar Quinga, Luis Felipe
The present work is a study that analyzes the displacements of people in private vehicles, from the valleys to the hypercenter of the Metropolitan District of Quito. A study of times, costs and use of the private vehicle from the Valle de los Chillos and Cumbayá to Quito at peak hours on a daily and monthly basis. At the same time, it is proposed to create an integrated transport system that includes parking lots outside the hypercenter, interconnection buses and the Quito Metro. These two transport methods are compared and analyzed in the context of time and costs. For the measurement of transport times in a private vehicle, the transfer time from the determined points is investigated on-site daily at peak hours, in addition to establishing the cost structure for this type of transport and routes, using the method of the shortest route. For the integrated system, the parking capacity and its tariffs are established, a method of connection with the stops of the Quito Metro is established through the shortest route, and its tariffs and transfer times are established. Finally, these two systems are compared and the method that uses the lowest cost and time is analyzed.

Análisis del impacto de las pérdidas de frutas y vegetales en términos biofísicos: caso de estudio mercado mayorista de la ciudad de Quito
Fajardo Caizaluisa, Daysi Paulina
Sangacha Robalino, Edwin Vinicio
The present study analyzes the Impact of the Losses and Waste of fruits and vegetables in biophysical terms in the Public Company Mercado Mayorista de Quito; the waste generated in relation to the products that concern the study is quantified, for which, the quantification methods proposed by the Commission for Environmental Cooperation are used, as well as a survey of market traders, with which they identify: demographic characteristics of the population, habits and customs on waste management and the causes that generate waste. Once the information has been collected, the analysis is carried out based on the MuSIASEM methodology, to find the biophysical loss, which originates due to fruits and vegetables that were not handled and used efficiently.
The weekly waste of fruits and vegetables is obtained, as well as the products that generate the greatest amount of waste in the two groups, of which the environmental loss is calculated. In addition, you can identify the causes that generate the PDA in the phases of distribution and wholesale. In addition, the study proposes an improvement plan for inconveniences related to food loss and waste, and for the general functioning of MMQ-EP.

For this investigation first we will identify the most relevant production factors for the association of San Rafael Agricultural Producers with the help of the Likert technique, and also calculate the efficiency before the implementation of the technified irrigation project and after the implementation of the project, using data provided by the Agriculture and cattle Ministry, as a tool of analysis, the DEA method will be used in conjunction with the DEAP 2.1 software. Finally it will be identified the variation that has surpassed the productivity behind the implementation of the drip irrigation system with the aid of the Malmquist index. For this purpose, we will work with the data of consecutive periods of time with the aid of DEAP software 2.1. The result of this work will assist in the decision-making by the governmental authorities regarding the implementation of future technified irrigation project

Caracterización biofísica y cuantificación de desperdicios del sector cárnico de la ciudad de Quito: caso de estudio Empresa metropolitana de rastro Quito EMRAQ-EP
Auz Rosero, Verónica Anabel
Chérrez Gavilanes, Christian Wladimir
According to the UN for the year 2026, forecasts indicate that meat production will increase by 13% compared to the 2014-2016 period. On the other hand, health control agencies seek to achieve a balanced diet to prevent diseases, where meat proteins will replace carbohydrates; consequently, the slaughter process must be efficient to achieve maximum utilization of the slaughtered animal. This research has the purpose of evaluating losses and waste in a slaughterhouse, taking as reference the EMRAQ-EP for its capacity of 600 cattle per day in addition to other species. Based on the EMRAQ-EP records, losses and wastes were determined in biophysical terms related to water-soil-energy, of the species: cattle, pigs and sheep. To perform this analysis, we worked with the MUSIASEM methodology, an instrument that allows us to know the socio-ecological system by identifying the weaknesses and potentials of the food system. The results show the values of losses and waste to have a clearer vision and achieve reduction in meat production, also providing proposals to optimize slaughter processes and the reuse of derivatives.

Análisis de la producción de la hilandería intercomunal salinas (HIS).
Rosero Narváez, María Augusta
This research work analyzes the production of Intercommunal Spinning Mill: Hilandería Intercomunal Salinas (HIS). The mill was founded in 1987, in Salinas of Guaranda, located in the Bolivar Province. This work identifies and documents the manufacturing process of it’s yarn wool product. It also examines the performance of said process, by using the historical data to quantify the production indexes. Those results are then used to propose the implementation of the 5S methodology as a continuous improvement tool.
This research has descriptive-non-experimental scope and focuses on quantitative analysis. The information was collected: during visits to the HIS Mill, interviews with managers, bibliographic documentation reviews and the compilation of manufacturing records.
The results of the spinning mill's production performance analysis reveals: the efficiency varies between 15% and 85%, and the plant utilization is below 50%. Therefore, the use of the S5 methodology is proposed, as an elementary tool to eliminate waste and activities that unnecessarily consume resources. This will improve the efficiency and performance of the productive processes.

Análisis del impacto de la incertidumbre en la gestión de inventarios en una empresa que opera en el sector petrolero y propuesta de un sistema de control de ítems agrupados
Guanoluisa Acero, Lorena Jacqueline
This research project analyzes the incidence of uncertainty in inventory management in a company that operates in the oil sector. In the first instance, the suppliers and products of greatest relevance to the company are established, using the Analytic hierarchy process (AHP), in which three criteria for suppliers and four criteria for products were considered, defining two categories, one for purchasing products. national and another for international purchase products. With the established suppliers and products, the historical demand data is consolidated, with which the coefficient of variation was calculated, and the type of demand managed by the company was established. Other relevant data in the study are delivery time, ordering costs, service levels and unit value. The data acquired allows the calculation of exchange curves, in which the current situation of the company was analyzed and what would be the optimal scenario by comparing the relevant total cost at each point of the curve. The final part of this work allows proposing an inventory control system considering the effect of uncertainty and based on the relevant total cost.

Aplicación de una heurística de optimización para el balanceo de mallas curriculares de tres carreras técnicas de la Escuela Politécnica Nacional
Zambrano Pérez, María José
The present work is oriented in the characterization and balancing of curricular meshes of three careers of the National Polytechnic School (EPN), through the heuristics used in the balancing of production lines. The collection of primary data was carried out by means of unstructured interviews with the Subdecane of the Faculty of Mechanical Engineering and the Director of Teaching of the EPN with regard to the elaboration of curricular meshes. Secondary data were obtained through the documentary analysis of curricular meshes and the Academic Regime Regulations. The secondary data were previously selected and organized in a precedence diagram to be analyzed using the positional weights heuristic (Helgeson and Birnie method). The inactivity time for each semester and the total time were determined, as well as the percentage of efficiency of each curriculum mesh before and after balancing. It resulted in a total efficiency of 100% and a zero-hour downtime in the meshes of the Production Engineering and Electronic Engineering and Automation careers. The mesh of the career of Mechanical Engineering presented some downtime within each semester and therefore efficiencies less than 100%, however, the total efficiency was 100%, After the balancing, an optimal solution was obtained with which the downtime was reduced from 210 hours to 10 hours and the total efficiency was maintained at 100 %.

Análisis de la estructura de la cadena de suministro en restaurantes ubicados en el centro y norte de quito, en el contexto provocado por el covid-19.
Pichucho Andrade, Carlos Alexander
The pandemic caused by COVID-19 was a disruptive event with consequences for the supply chain
management of all companies around the world. Micro and small companies do not have at their disposal the
resources of larger companies, and therefore the recovery measures they adopt respond to a different reality. In
this context, this descriptive work analyzes the current structure of the supply chain of Fourth and Third
Category restaurants considered micro and small companies. It describes the members that make up the supply
chain, the relationships between them, the barriers perceived as a result of the context of the pandemic, and the
recovery measures adopted to keep the restaurants operational. Finally, the role played by cooperative
relationships is analyzed, understood as a stage in the integration of the supply chain of organizations and a
means of recovery or mitigation of the negative effect of barriers. It is found that there is a predominance of
direct suppliers of raw materials, which are wholesale and retail markets, where products are purchased without
transport intermediaries. Members who are currently critical to the operational development of restaurants were
identified, such as customers who buy at home. The general level of integration between the members of the
chain and the restaurants under study, is also quantitatively indicated and the possibility of creating cooperative
relationships based on the measurements made is formulated.

Análisis del impacto de la emergencia sanitaria provocado por la pandemia del Covid-19 en la cadena productiva de artesanos calificados dedicados a la elaboración de prendas de vestir en la ciudad de Quito.
Criollo Apolo, Mauricio Julio
This research analyzes the effects of the health crisis caused by the Covid-19 pandemic on the production chain
of small companies engaged in the manufacture of garments and that possess an artisan qualification granted by
the National Board for the Defense of Artisans (JNDA) in Quito city. The methodology is of a descriptive
exploratory nature; surveys were used as a tool to obtain data from a sample of qualified artisan companies.
The data were processed with statistical tools to determine trends in the phenomena studied. The results
indicated that the government and support institutions failed to establish policies that benefit the actors in the
chain; variations in raw material costs had a negative influence. Mobility problems, the implementation of
teleworking, the shortening of working hours and the personnel reduction were also factors that directly
affected the chain. There were cases of Covid-19 among the actors in the chain, but not all employees had
social insurance. The use of technology, especially electronic commerce and social networks, facilitated
communication between chain actors. It is concluded that the production chain of skilled artisans is weakened.
The research has reflected the lack of public policy procedure, which has failed to benefit the sector in the
context of the pandemic. The need to strengthen the leadership of the guild and improve relations with the
companies linked to the productive chain is evident.

Freire Montenegro, Sandy Macarena
At the national level, the economic impact caused by the covid-19 pandemic mainly affects Small and Medium
Enterprises. Due to the pandemic, small businesses deliver the products to home. The evaluation of the quality
of service is essential since it improves the performance of organizations, this is how customer satisfaction is
directly related to the quality of service. The objective of this study was to evaluate the quality in the delivery
of bedroom line products in the supply chain as a consequence of the covid-19 pandemic. As a study unit, the
clients of a small company that sells home products for the home were sampled. The methodology of this
research is quantitative because the perception and expectation of the client regarding the quality of service
received was analyzed. The scope of the research was exploratory regarding the quality of delivery of bedroom
line products. The tool used was the survey based on the SERVQUAL model. The results obtained allowed to
obtain the dimension of the SERVQUAL survey with the greatest difference between the expectation and the
perception of the client. In conclusion, the quality of service of bedroom line home products does not meet
people's expectations.

Análisis de las competencias digitales de los docentes (CDD) de la Escuela Politécnica Nacional (EPN) en el contexto de la emergencia sociosanitaria causada por el covid-19..
Núñez Yépez, Paul Alexander
In march 2020, due to virus COVID-19, Ecuador underwent a change in the normal course of higher education, the State authorities announced the suspension of face-to-face teaching in universities, forcing all educational institutions and their teachers to transition to online teaching. The National Polytechnic School had to face the challenges of the transition, noting the relevance of teacher training in the use of technological tools and especially that they are competent in the digital environment so that the impact of this transition is less. Faced with this context of socio-health emergency, the purpose of analyzing the digital competencies of teachers of the National Polytechnic School (EPN) arose, through a self-assessment based on a questionnaire developed in Spain and validated for the Latin American context. This instrument was sent to a sample of EPN teachers and the responses allowed measuring the level of digital competence with respect to the years of experience, age and gender of each one, finding similar results to other research related to the same topic. The results showed that most teachers have an expert level in digital competencies; however, when analyzing the competencies with respect to their dimensions, there was evidence of opportunities for improvement in the management of digital tools, as well as that age is inversely proportional to the level of self-perceived digital competency and that years of experience and gender are not related to this level.

The work below presents the analysis of the current situation of the José Rubén Orellana Campus (hereinafter referred to as JRO) in energy-electrical terms in the context of what is required in a higher education institution so that it can be considered as a sustainable campus. To this end, in the third chapter the methodology is presented, focusing on the relevant energy analysis for a sustainable campus. In this sense, the guidelines established by the UI GreenMetric Wold University Ranking have been adopted, which is an initiative of the University of Indonesia launched in 2010, and which has currently been adopted by more than 950 universities and more than 80 countries. on a global scale. Based on these guidelines, in the fourth chapter, for the analysis of the current situation of this case study, four indicators are considered, which are closely linked to the subject in question. These are: start-up of smart buildings, renewable generation systems installed on the university campus, net energy consumed divided by the campus population (kWh per person) and the relationship between the production of renewable energy with respect to the net use of energy. in a year. Based on the findings reached after the analysis of the current situation based on the indicators detailed above, a proposal is made that can potentially be adopted so that, after eventual compliance, the institution can improve them.

Criollo Chávez, Danilo Santiago
The objective of this research is to develop a socio-demographic credit score model for a Public Micro financial Institution in Ecuador whose focus is natural persons and not small and medium enterprises. The results of this research develop a methodology and the steps needed to design the statistical model, and the assessment and validation process that can be applied in the Ecuadorian geography to establish financial inclusion policies with customers with no credit history. Finally, this work also explains the performance of the model over future periods and how it can be used to develop credit risk management approaches for credit exceptions and limits of risk appetite.
