Gallegos Teramoto, Desire Marjorie, Pinedo De La Cruz, Brigham Spencer 15 September 2020 (has links)
El sistema Lean y la metodología Kaizen tienen como objetivo principal la mejora continua, alineado a ello este trabajo presenta un sistema integrado, donde se combinan y complementan las 2 metodologías. El sistema denominado Lean Kaizen se basa en el enfoque de objetivos y la interrelación de herramientas. Entre ellas se han elegido: Equipos Kaizen, Value Stream Mapping, Estandarización de Procesos y Gestión Visual. Estas permitirán identificar el flujo de valor en el proceso, eliminando actividades innecesarias y controlando el proceso crítico. El sistema propuesto se aplica en la industria de venta directa en Perú. La evaluación inicial se realizó a través de encuestas. Los resultados muestran que el principal problema de las empresas del rubro en mención es la insatisfacción a causa del retraso en el servicio de atención. En este caso, se utilizó una empresa para validar la metodología propuesta mediante una Prueba Piloto, como método de validación. Es así como se verá la factibilidad de reducir tiempos, mejorar el nivel de servicio, permitiendo un aumento del 23% en el indicador de fidelización NPS y elevar el nivel de servicio en un 12%. Finalmente, se concluye que Lean Kaizen es una poderosa herramienta que permitirá al sector de venta directa e, incluso a otros, a lograr la mejora continua. / The Lean system and the Kaizen methodology have as main objective the continuous improvement, aligned to this this work presents an integrated system, where the 2 methodologies are combined and complemented. The system called Lean Kaizen is based on the focus of objectives and the interrelation of tools. Among them have been chosen: Kaizen Teams, Value Stream Mapping, Process Standardization and Visual Management. These will allow to identify the flow of value in the process, eliminating unnecessary activities and controlling the critical process. The proposed system is applied in the direct sales industry in Peru. The initial evaluation was carried out through surveys. The results show that the main problem of the companies in the field in question is dissatisfaction due to the delay in the attention service. In this case, a company was used to validate the proposed methodology through a Pilot Test, as a validation method. This is how the feasibility of reducing times, improving the service level, allowing an increase of 23% in the NPS loyalty indicator and raising the service level by 12% will be seen. Finally, it is concluded that Lean Kaizen is a powerful tool that will allow the direct selling sector and even others to achieve continuous improvement. / Trabajo de investigación

Modelo de mejora de procesos de reparación de cilindros hidráulicos empleando metodologías ágiles en sector metalmecánico / Model for the improvement of hydraulic cylinder repair processes using agile methodologies in the metalworking sector

Canales Membrillo, Sergio Maximiliano, Espinoza Navarro, Gabriela del Pilar 12 January 2021 (has links)
En la presente investigación, se evalúa la situación actual de una empresa del rubro metalmecánico, dedicada a la reparación y fabricación de cilindros y pistones hidráulicos y neumáticos. Se identificó que el problema principal es el exceso de tiempos de atención de las órdenes de trabajo recibidas, que retrasan la producción y su entrega final. Se tomó como referencia al tiempo total abarcado en el proceso desde que se genera la orden de atención hasta su entrega al cliente. En base al análisis realizado, se observó que los tiempos son generalmente dilatados en los procesos iniciales de evaluación y cotización, agrupados como procesos de diagnóstico. Asimismo, se pudo identificar que en estos procesos existían varios periodos de espera injustificados, por desorden o dejadez de los encargados. A pesar de ser un problema recurrente en empresas de este sector, existen pocas investigaciones que sustenten una metodología para la mejora. Por ello, se busca implementar un modelo híbrido entre dos metodologías ágiles: Lean Manufacturing y Quick Response Manufacturing, con la finalidad de reducir desperdicios como espera, reducir el lead time, aumentar la productividad y lograr abarcar mayor cantidad de órdenes de atención. Finalmente, luego de implementar un plan piloto de validación de resultados en los tres procesos principales, se observa que la ratio de On time deliveries (OTD) se incrementó de un 37.5% a 58.82%, demostrando que se redujo el tiempo de atención y se incrementó el tiempo de valor agregado en los procesos. / In the present investigation, the current situation of a company in the metalworking industry, dedicated to the repair and manufacture of hydraulic and pneumatic cylinders and pistons, is evaluated. It was identified that the main problem is the excess of attention times of the work orders received, which delay the production and its final delivery. It was taken as a reference to the total time covered in the process from the moment the service order is generated until its delivery to the customer. Based on the analysis carried out, it was observed that times are generally long in the initial evaluation and quotation processes, grouped as diagnostic processes. Likewise, it was possible to identify that in these processes there were several unjustified waiting periods, due to disorder or neglect of those in charge. Despite being a recurring problem in companies in this sector, there is little research that supports a methodology for improvement. Therefore, it seeks to implement a hybrid model between two agile methodologies: Lean Manufacturing and Quick Response Manufacturing, in order to reduce waste as expected, reduce lead time, increase productivity and achieve a greater number of service orders. Finally, after implementing a pilot plan for the validation of results in the three main processes, it is observed that the ratio of On time deliveries (OTD) increased from 37.5% to 58.82%, showing that the attention time was reduced and increased value-added time in processes. / Trabajo de investigación

Un modelo para mejorar el cumplimiento de las entregas a tiempo a través de MRP, TPM Y SLP en el sector construcción modular / A model to improve the fulfillment of deliveries on time through MRP, TPM and SLP in the Modular Construction Sector

Luyo Muñoz, Alisson Mabel, Sanchez Flores, Katherin Leonor 04 April 2021 (has links)
Las entregas a destiempo son un problema recurrente en las empresas que representan un mercado incipiente pero también muy importante en la satisfacción de los clientes. Se presentan diversos factores que permite el retraso de los pedidos, como la planificación inadecuada de los materiales, los tiempos muertos y una distribución de áreas ineficientes en la planta de producción. Para optimizar el cumplimiento de las entregas a tiempo y reducir costos generados por el problema, se desarrollará una propuesta de mejora representado por un modelo combinado esquematizado en tres fases, utilizando la planificación del diseño sistemático (SLP), la planificación de los requerimientos de material (MRP) y Mantenimiento Productivo Total (TPM). El artículo se basará en un caso de estudio en el rubro de la construcción modular con un tipo de producción bajo proyectos, demostrando que el método desarrollado aumentará la precisión de la entrega de los pedidos en la fecha requerida. Dentro de las mejoras obtenidas luego de la validación, se logró superar el 50% de reducción tanto en el desplazamiento como en el tiempo. También se logró cumplir con el despacho de los materiales en un 95.74%. Además, en el proceso de compras se lograron emitir ordenes de acuerdo al proceso de producción, obteniendo así un cumplimiento del 92.10%. Por último, luego de la ejecución de los principales pilares del programa del mantenimiento productivo total, se obtuvo un incremento en el OEE de 37.67%, alcanzando el 97.76%. / Untimely deliveries are a recurring problem in companies that represent an incipient market but also very important in customer satisfaction. There are various factors that allow order delays, such as inadequate material planning, downtime, and inefficient area distribution on the production floor. To optimize the fulfillment of deliveries on time and reduce costs generated by the problem, an improvement proposal will be developed represented by a combined model outlined in three phases, using the systematic design planning (SLP), the planning of material requirements (MRP) and Total Productive Maintenance (TPM). The article will be based on a case study in the field of modular construction with a type of production under projects, showing that the method developed will increase the precision of the delivery of orders on the required date. Among the improvements obtained after validation, it was possible to exceed a 50% reduction in both travel and time. It was also possible to comply with the dispatch of materials by 95.74%. In addition, in the purchasing process, orders were issued according to the production process, thus obtaining a compliance of 92.10%. Finally, after the execution of the main pillars of the total productive maintenance program, an increase in OEE of 37.67% was obtained, reaching 97.76%. / Trabajo de investigación

Propuesta de un Modelo de Referencia de la Gestión de Proyectos y Calidad para mejorar el tiempo y costo ejecutados en los bienes y servicios de una PYME del Sector Eléctrico, basados en las herramientas Lean y PMBOK / Project Planning Methodoly base don Lean Philosophy and PMBOK Guidelines for SMEs in the Electricity Sector

Bazan Cantorin, Denisse Elizabeth, Pinedo Soriano, Marco Junior 19 February 2021 (has links)
En la actualidad, muchas empresas que ejecutan proyectos eléctricos carecen del conocimiento teórico sobre el cómo desarrollarlos correctamente debido a que se basan en el conocimiento empírico. Por tanto, presentamos una nueva forma de dar soluciones prácticas y económicas a las organizaciones; la propuesta a presentar es la ejecución de 2 enfoques como lo son la filosofía lean y gestión de proyectos. A través de la recopilación de los casos de estudio, la literatura cita una demostración sobre la importancia de realizar una apropiada planificación en base a los pilares del costo y tiempo que deberían identificarse y mejorarse para garantizar mejores resultados, estos pilares fueron analizados a través de las herramientas de Ishikawa y árbol de problemas. Para ello, se escogieron algunas de las herramientas lean como lo son: 5’S, gestión visual y círculos de calidad, las cuales mediante las directrices de la gestión de proyectos, específicamente los 47 procesos publicados en la 5ª edición del Cuerpo de Conocimientos de Gestión de Proyectos, dictaminaron el modelo desarrollado en la investigación en una empresa piloto donde se contrastaron los resultados del cómo esta combinación de soluciones disminuyen los plazos de entrega en dicha organización / Currently, many companies that execute electrical projects lack the theoretical knowledge on how to develop them correctly because they are based on empirical knowledge. That is why it has developed from the need to implement the lean philosophy and project management as distinctive and well-known pillars that guarantee high competitiveness in the market of the sector under study. Through the compilation of case studies, the literature cites a demonstration on the importance of making appropriate planning based on the cost and time pillars that should be identified and improved to guarantee better results. These pillars were analyzed using the Ishikawa tools and problem tree. For this, some of the lean tools were chosen such as: 5'S, visual management and quality circles, which through the project management guidelines, specifically the 47 processes published in the 5th edition of the Body of Knowledge of Management of Projects, ruled the model developed in the research in a pilot company where the results of how this combination of solutions decrease delivery times in said organization were contrasted. / Tesis

The Influence of Selected Non-Cognitive Factors in The Flourishing and Intention to Quit Studies of Working Students at A University in the Western Cape

Amadi, Winston Aligbaso January 2020 (has links)
Magister Commercii (Industrial Psychology) - MCom(IPS) / Working students encounter challenges and responsibilities at university and work. In attempting to study the books and chapters assigned, meet assignment deadlines, take part in extracurricular activities and function at work, working students may be overwhelmed sensing inadequate time to complete all their responsibilities. These may lead to certain negative outcomes for the working student, such as languishing, poor grades, taking longer than the expected time to complete studies or, in the worse scenario, quitting their studies. The primary aim of this study was to examine and understand the influence of non-cognitive factors (including PsyCap, time management, and grit) on flourishing and the working students’ intention to quit employing correlational and hierarchical regression analysis. The secondary objective was to make recommendations to universities and organisations on how to aid working students to develop or increase non-cognitive factors to ensure their flourishing and a reduced intention-to-quit studies. A non-probability sampling technique indicating, convenience sampling and purposive sampling were employed to recruit respondents. Respondents had to be working students (part-time students). The sample included 194 respondents (n = 194) from a university in the Western Cape. The survey instrument included a biographical questionnaire, the academic PsyCap questionnaire, mental health continuum - short form (MHC-SF) questionnaire, Grit-Perseverance of effort subscale, the time management short-range planning subscale, and a self-developed intention-to-quit questionnaire. Numerous studies confirmed the validity and reliability of these instruments. The relationship amongst the non-cognitive variables (PsyCap, grit and time management), flourishing and intention-to-quit studies were assessed through Pearson correlation and hierarchical regression analysis. The non-cognitive variables had a positive relationship with flourishing and a negative relationship with intention-to-quit studies. PsyCap was established to explain the largest proportion of the variance in flourishing and intention-to-quit studies. This is consistent with the findings of studies with similar variables. Recommendations were made for lecturers, counsellors, and university officials to collaborate to incorporate programmes that will aid in developing these non-cognitive variables into the university’s curriculum.

Diseñar una propuesta de mejora en el modelo Inbound Marketing aplicando herramientas de clasificación ABC y marketing B2B para incrementar el índice de conversión de cotizaciones a ventas en empresas distribuidoras de régimen pyme / Design a proposal for improvement in the Inbound Marketing model by applying ABC classification tools and B2B marketing to increase the rate of conversion of quotes to sales in SME distribution companies

Cruz Alfaro, Milagros Gisell, Gálvez Torres, Erika Katerine 03 May 2021 (has links)
En la actualidad las empresas pymes distribuidoras presentan algunos inconvenientes en el mercado, porque no pueden competir con éxito algunos factores como sus precios, logística o calidad de los productos, entre otras características con las empresas. Asimismo, estas empresas les falta enfocarse en los procesos pre o post el pedido de compra del cliente. Antes de cumplir 2 años activos en el mercado peruano, el 82.5 % de las empresas pymes se disuelven. La empresa en la que se enfoca este trabajo se llama es especializada en la distribución de herramientas manuales, eléctricas y neumáticas, la cual fue analizada para identificar los problemas principales y las posibles causas. En la lectura y análisis de los artículos científicos encontrado, se plantea una metodología de mercadotecnia llamada Inbound Marketing, en la cual se modificado y adecua para el caso de estudio del presente trabajo.  Por otro lado, se ha utilizado herramientas como clasificación ABC, flujo de trabajo y metodología de Inbound Marketing como estructura de la metodología propuesta para poder solucionar el problema de ventas insuficiente. Se ha analizado que las causas principales de esta problemática de diferentes pymes es el bajo índice de conversión de cotizaciones a ventas, lo cual genera el poco rendimiento e impacto económico negativo. Al finalizar la implementación de esta metodología, se refleja un incremento en el porcentaje de eficiencia del desarrollo de cotizaciones y un aumento en el índice de rendimiento de estos. En conclusión, se puede medir el impacto monetario de la implementación que ha sido beneficioso para la empresa en estudio, el rendimiento que se obtuvo en el último mes de implementación fue el aumento en un 10 %. Por ello, se recomienda realizar esta propuesta para adaptarla a situación actual de cualquier pyme. / Currently, SMB distribution companies have some drawbacks in the market because some factors such as their prices, logistics or product quality, among other characteristics with companies, cannot compete successfully. These companies also need to focus on the pre or post processes of the customer's purchase order. 82.5% of SME companies disappear before two years of market existence. The company is a specialized in the distribution of manual, electrical and pneumatic tools, which was analyzed to identify the main problems and possible causes. In the reading and analysis of the scientific articles found, a marketing methodology called Inbound Marketing is proposed, in which it is modified and adapted for the case of study of this work.  On the other hand, tools such as ABC classification, workflow and Inbound Marketing methodology have been used as the structure of the proposed methodology to be able to solve the insufficient sales problem. It has been analyzed that the main causes of this problem of different SMEs is the low rate of conversion of quotes to sales, which generates the low yield and negative economic impact. At the end of the implementation of this methodology, an increase in the percentage of efficiency of the development of quotes and an increase in the rate of return of quotes is reflected. In conclusion, you can measure the monetary impact of the implementation that has been beneficial to the company under study, the performance obtained in the last month of implementation was the increase by 10%. It is therefore recommended that this proposal be made to adapt it to the current situation of any SME. / Tesis

Mani, Tshiangwa Adolphina January 2020 (has links)
Thesis (M. A. (Nursing)) -- University of Limpopo, 2020 / Background: Long patient waiting time for services is demonstrated by daily long queues of patients in Primary Health Care (PHC) and hospitals Outpatients departments. Aim: The aim of the study was to determine the factors contributing to long waiting time at Blouberg Health Centre (BHC), Capricorn District, Limpopo Province. Methods: A quantitative, descriptive and cross-sectional research design was used to describe factors contributing to long waiting time. The study population consisted 31356 patients in the financial year 2017/2018. Simple random probability sampling was used to select 395 respondents. Data were collected using self-developed questionnaire. All questionnaires were completed and returned. The 395 questionnaires were then analyzed using the Statistical Package for Social Sciences (SPSS, version 25). Descriptive statistics were used to analyze and describe and summarized data. Findings: The findings were presented in the form of distribution graphs and tables. Inferential statistics were used based on probability and allowed judgement to be made about variables. The study revealed factors considered most important were lack of commitment; full time study leaves at the same year; workshops; sick leaves; increased population; sitting in tearoom for hours; many foreign national without passports; staff shortages; laissez faire working style and transfers or escorting patients, while the nearby Hellen Franz Hospital (HFH) also transfer to the same hospitals, leading to mismanagement of budget reduced manpower and increased death rate. Recommendations: The study recommends that all Primary Health Care (PHC) settings should use numbers for patients when entering facilities to monitor the queuing and prevent dissatisfaction that can result from long waiting. Conclusion: It is of paramount importance to provide clearer, transparent information to the recipients of the Primary health care services that they might receive. The provincial coordinators are accountable to the waiting time management with the assistance of the PHC specialist nurse and Nursing Management.

Propuesta de mejora del proceso de fabricación de ventiladores utilizando la metodología Lean Manufacturing para mejorar el nivel de servicio / Proposal to improve the fan manufacturing process using the Lean Manufacturing methodology to improve the level of service

Vásquez Nuñez, Armando, Quispe Huayhua, Milagros Natali 02 May 2021 (has links)
Este estudio revela el problema de una empresa metalmecánica que se dedica a la fabricación de ventiladores Industriales, colectores de polvo, lavadores de gases, etc. Se analizó el problema principal de la empresa KT PERU SAC que es en el retraso de entrega de sus pedidos hacia sus clientes, provocando constantes quejas y retraso de pagos. El estudio de tiempos se realizó en el proceso de fabricación del ventilador centrífugo, ya que era el que mayores ventas nos generó en los últimos años y también el que mayor tiempo tarda un técnico de fabricarlo. Después de haber realizado el estudio de tiempos guiándonos de artículos, se implementaron herramientas Lean Manufacturing para reducir los tiempos improductivos y en consecuencia entregar los pedidos a tiempo y calidad. Para el diagnóstico del problema utilizamos el VSM y grafica de control por variables, las herramientas de ingeniería que implementamos fueron el SLP y 5´S para el primer motivo de Tiempos Improductivos, luego el Kanban para los reprocesos de fabricación y finalmente gestión de Inventarios para un abastecimiento eficiente de materiales. Con estas herramientas de ingeniería seleccionados llegaremos a cumplir con la entrega a tiempo de pedidos a los clientes, por lo cual no habría quejas y los pagos serían a tiempo. / This study reveals the problem of a metalworking company that is dedicated to the manufacture of Industrial fans, dust collectors, gas scrubbers, etc. The main problem of the company KT PERU SAC was analyzed, which is the delay in the delivery of its orders to its customers, causing constant complaints and late payments. The time study was carried out in the centrifugal fan manufacturing process, since it was the one that generated the highest sales in recent years and also the one that took the longest time for a technician to manufacture it. After having carried out the study of times guiding us of articles, Lean Manufacturing tools were implemented to reduce unproductive times and consequently deliver orders on time and quality. For the diagnosis of the problem we used the VSM and variable control graph, the engineering tools that we implemented were the SLP and 5´S for the first reason for Downtime, then the Kanban for manufacturing reprocesses and finally Inventory management for an efficient supply of materials. With these selected engineering tools we will be able to deliver on time orders to customers, so there would be no complaints and payments on time. / Trabajo de Suficiencia Profesional

RekUpp – Utvecklingsprocessen bakom ett systemför självreflektion och kursutveckling

Windefelt, Andreas January 2022 (has links)
Ett hinder inom utbildningar på högre nivå har sedan länge varit att det är svårt förlärare att få en bild över hur det går för studenterna som överensstämmer medverkligheten. De områden som förmodas vara svåra kanske inte upplevs som detav studenterna, och vice versa. Utöver direkta frågor från studenter så behöverlärarna gissa sig fram till vad studenterna upplever som svårt, vilket inte ger en sannbild.Inom vissa tekniska och matematiska utbildningar rekommenderar lärare övningarsom studenterna förväntas göra för att skapa en förståelse för området. Det finnsen risk att studenter inte genomför uppgifterna löpande utan i stället spenderarmycket tid vid kursens slut. Det ger inte samma djupa kunskap som att kontinuerligtstudera.Lärare publicerar vanligen de uppgifter som rekommenderas i en textfil påtillgänglig utbildningsplattform, vilket inte ger möjlighet att lösa de problem somtidigare nämnts. Förslaget är därför RekUpp (Rekommenderade Uppgifter), enwebbapplikation som lärarna ska kunna använda för att föreslå uppgifter somstudenterna bör utföra. Programmet är skräddarsytt för att engagera studenternai reflektion angående sin egen prestation samt ge förutsättningar för att bättrehantera sin egen studietid. Informationen och den data som uppstår kan lärarnaanvända på bästa sätt för att övergripande analysera studenternas prestationer påkursen. Programmet förväntas både bidra till att lösa problemet med brist påinformation och till att engagera studenter.I det här arbetet redovisas utvecklingsprocessen. Denna baseras på tidigareforskning kring självreglering, självreflektion och digitala verktyg för att på bästamöjliga sätt engagera studenter och samtidigt få ut information som lärare kananvända för att justera och förbättra undervisningen. Tanken är att utvecklingen avsystemet, och de slutsatser som presenteras, ska kunna användas somutgångspunkt eller ramverk för att utveckla liknande system. / An obstacle in higher education has for a long time been that it is difficult forteachers to get an overview for how the students are performing. The parts of thecourse that are believed to be hard may not be, and vice versa. Beyond directquestions from students, teachers must guess from the best of their ability aboutwhich exercises that the students experience as difficult.Within certain technical and mathematical educations, it is common for teachersto recommend exercises that the students are expected to complete to get anunderstanding of the field. There is a risk that students don’t do these exercisescontinuously and instead spend a lot of time studying ahead of an exam at the endof the course. This does not give the same deep knowledge as continuous studydoes.Teachers tend to publish these exercises in a text file on an available learningplatform, this does not solve the problems mentioned previously. A suggestion fora solution is RekUpp (from the Swedish translation of Recommended exercises), aweb application that teachers can use to publish which exercises students aremeant to do. The program is tailored to engage students in self-reflection abouttheir performance and give them prerequisites for better time management. Theinformation and data that is created can be used by teachers to analyze how thestudents are performing. The system is expected to contribute to solving both theproblem of a lack of information and to continuously engage students.In this report the development process is described. This is based on previousresearch about self-regulation, self-reflection, and digital tools to engage studentsin the best possible way and at the same time transfer information that teacherscan use to adjust and improve their courses. The intention is that the developmentof the program, and the conclusions that are presented, can be used as a startingpointor framework to develop similar systems.
