Marcolová Klímková, Markéta January 2013 (has links)
The dissertation thesis is focused on increase of the efficiency of production processes in Czech companies, whose main work focus is electric motor production with usage of the lean manufacturing tools with the environmental management system. The main reason for choosing this topic were results of prime study of the target group of companies which has proved that companies do have trouble not just with integration but especially with implementation of the lean manufacturing methods. This is the reason why concrete conditions and basic principles need to be defined to show how to proceed. The objective of this dissertation thesis is to suggest the model of integration of lean manufacturing tools with optional environmental management tool and as the lean manufacturing tools were chosen methods of lean management in production and as an optional environmental tool was chosen system of environmental management based on norm ISO 14 001. For this area of interest the primary and secondary research was used. Based on knowledge from detailed research of Czech and foreign literary sources a survey and guided interview was started with companies, which are focused on electric motor production. The thesis contains a detailed evaluation of empirical research with testing of stated hypothesis, based on which the verbal model of the integration of the lean manufacturing tools with the environmental management system is assembled. The implantation based on the suggested verbal model of the integration in the company should lead not just to the relationship improvement between the company and the environment but also to better understanding of the relationship of two independent kinds of company management leading to saving money, working environment improvement, productivity increase or ecological onus decrease. The benefits can be seen in theoretical, practical and also pedagogical level.

3D Printed Customized Tooling Development Approach

Thawaba, Sami January 2021 (has links)
3D printing technologies have been gaining a lot of popularity in the last fifteen years, technologies like Fused Deposition Modeling (FDM) 3D printing have never been as accessible as they are today, and with the introduction of the desktop 3D printer, the technology is becoming a mainstream tool for developing prototypes and direct part production from a Computer-Aided Design (CAD) file. In an industrial context, the technology is utilized for different purposes, among which is the development and production of customized and task-specific tools. The proposed work in this thesis is an approach to simplify and streamline the development process of customized production tooling and workstation. The approach was used to identify problems and improvement opportunities at a production facility that delivered IT products. Furthermore, the Technical framework included in the proposed approach provided a guiding path to follow for the prototype development of tools to address identified problems. Developed tools and proposed solutions positively affected the production line work procedure and were accepted and adopted. While other solutions required further exploration and iterative cycles as some reluctance was experienced hence it implied changes in the workflow and daily routines.

Irkñampa Seminario, Leyla Carolina, Ruiz Tacuri, Katherine Mercedes 23 July 2021 (has links)
Lean Manufacturing (LM) en la actualidad, es una de las metodologías de trabajo más aplicadas en las compañías que buscan eliminar los desperdicios de la operación, en base a la filosofía de mejora continua. Esto con el fin de que sus procesos internos se vuelvan más esbeltos y por ende más eficientes. En el presente estudio se podrá apreciar cómo un modelo de mejora basado en la combinación de algunas herramientas Lean tales como VSM, SMED y Manufactura celular, puede ser aplicado para optimizar las operaciones de una empresa de supermercados que produce panes a gran escala y de manera automatizada. Los panes son elaborados en una planta de producción de alimentos, para luego ser distribuidos a las distintas sedes del supermercado en donde se produce la venta final del producto. Algunos de los beneficios más relevantes que se identificaron después de la implementación de este modelo son el ahorro de costos de operación y distribución; así como el cumplimiento de la cuota de producción inicialmente planteada para la línea de panadería. / Lean Manufacturing (LM) is currently one of the most applied work methodologies in companies seeking to eliminate waste from the operation, based on the philosophy of continuous improvement. This in order that their internal processes become more slender and therefore more efficient. In the present study it will be appreciated how an improvement model based on the combination of some Lean tools such as VSM, SMED and Cellular Manufacturing, can be applied to optimize the operations of a supermarket company that produces bread on a large scale and in a automated. The breads are made in a food production plant, and then they are distributed to the different branches of the supermarket where the final sale of the product takes place. Some of the most relevant benefits that were identified after the implementation of this model are savings in operating and distribution costs; as well as the fulfillment of the production quota initially set for the bakery line. / Trabajo de Suficiencia Profesional

Además, presenta una pérdida de S/. 90,697.27 soles en el periodo 2019, debido al problema antes mencionado. Este impacto económico representa un 2.6 % de las ventas totales del año analizado. Por esta razón, se propone la implementación de las herramientas de Lean Manufacturing, a través de la implementación del trabajo estandarizado, se logró reducir los produc tos defectuosos por errores en coagulado y medida de cuajo de 0.9% a 0.6%; también, se redujo los productos con exceso de presencia de suero de 16.6% a 12% y finalmente, se redujo el tiempo de ciclo del proceso de cuajado de 74.6 minutos a 64.1 minutos. Mediante la implementación del TPM y la mejora continua, se logró reducir el porcentaje de fallas de la bomba centrífuga de 40% a 31%. Finalmente, se concluye que el proyecto es viable, ya que el VAN es de S/. 29,890.41 y un TIR de 57%. Además, el IR del proyecto de es de 2.83, esto quiere decir que por cada sol invertido se obtiene una ganancia de 1.83. / The present research work aimed to develop a proposal to improve the efficiency of fresh cheese production in a dairy company in Peru, using Lean Manufacturing tools. The company under study presents an efficiency of 61%, while the efficiency in Latin America is 95% and the efficiency of other companies in the sector in Peru is 70%. The low efficiency is due to three reasons, which are: defective products with a representation of 56.7%, unproductive times with 34.9% and functional failure of the centrifugal pump with 8.3%. In addition, it presents a loss of S /. 90,697.27 soles in the 2019 period, due to the aforementioned problem. This economic impact represents 2.6% of total sales for the year analyzed. For this reason, the implementation of Lean Manufacturing tools is proposed. Through the implementation of standardized work, it will be possible to reduce defective products due to errors in coagulation and rennet measurement from 0.9% to 0.6%; Also, the products with excess presence of whey were reduced from 16.6% to 12% and finally, the cycle time of the curdling process was reduced from 74.6 minutes to 64.1 minutes. Through the implementation of TPM and continuous improvement, the centrifugal pump failure rate will be achieved from 40% to 31%. Finally, it is concluded that the project is viable, since the NPV is S /. S/. 29,890.41 and the IRR is 57%. In addition, the IR of the project is 2.83, this means that for each sun invested a profit of 1.83 is obtained. / Trabajo de Suficiencia Profesional

Lean-användning i Sverige : En kvantitativ studie av svenska tillverkningsföretag / Lean in Swedish manufacturing companies : A quantitative study of Swedish manufacturing companies use of Lean manufacturing and management

Weber, Oscar, Haxhiu, Agonis January 2022 (has links)
Bakgrund och problem: Lean är en välkänd ideologi som företag implementerar för att bidra till bättre kvalitet, kortare ledtid, högre produktivitet, lägre tillverkningskostnad, större leveransprecision, högre lönsamhet, mer flexibilitet och högre engagemang hos medarbetare. Detta för att hänga med i marknadsförändringar samt att bli, och fortsätta vara, framgångsrika. Det finns många studier som undersöker samband mellan Lean och operationella samt finansiella prestationer bland olika stora tillverkande företag, dock finns det ingen sådan studie utförd just i Sverige. Där av är det intressant att se hur svenska företag upplever Lean och identifiera samband mellan Lean-verktyg och prestationsmått för att studera likheter och skillnader jämfört med studier utförda i andra länder. Syfte: Syftet med denna uppsats är att bidra till en ökad förståelse kring användningen av Lean i Sverige bland företag i tillverkningsbranschen samt förklara samband mellan användning av Lean-verktyg och prestationsmått (lönsamhet, kvalitet, tillverkningskostnader, leveransprecision, lagernivåer, ledtid, medarbetarnöjdhet och flexibilitet). Metod: En kvantitativ studie är utförd på svenska tillverkande företag i olika storlekar. Svar har samlats in från 95 respondenter i olika företag genom en webbaserad enkätstudie. Studien har anammat en deduktiv forskningsmetod med ett deskriptivt och förklarande forskningsändamål. Slutsats: Genom användandet av Lean-verktyg kan svenska tillverkningsföretag uppnå förbättrade operationella och finansiella prestationer. Företagets storlek, ålder eller lönsamhet påverkar inte förhållandet mellan Lean och prestationer, däremot kan explicit användning av Lean samt att engagera medarbetarna stärka de positiva effekterna av Lean. / Background and problematization: Lean is a well-known ideology that companies implement to contribute to better quality, shorter lead times, higher productivity, lower manufacturing costs, greater delivery precision, higher profitability, more flexibility and increased employee engagement. This is to keep up with the volatile market and to become and be successful. There are many studies that study the relationship between Lean and operational and financial performance among different sized manufacturing companies. However, there is no such study conducted in Sweden. Therefore, it is of interest to see how Swedish companies experience Lean and to identify correlations between Lean tools and performance measures to study similarities and differences compared to studies performed in other countries. Purpose: The purpose of this thesis is to contribute to an increased understanding of the use of Lean in Sweden among companies in the manufacturing industry and explain the relationship between the use of Lean-tools and performance measures (profitability, quality, manufacturing costs, delivery precision, inventory levels, lead time, employee engagement and flexibility). Method: A quantitative study has been carried out for Swedish manufacturing companies in different sizes. Answers have been collected from 95 respondents in different companies through a web-based survey. The study has adopted a deductive research method with a descriptive and explanatory research purpose. Conclusion: By using Lean-practices, Swedish companies can achieve improvements in both operational and financial performance. Company size, age or profitability does not affect this relationship between Lean and increased performance, although implementing Lean explicitly and engaging workers may further increase the positive effects of Lean.
