Applicability of ISO 56002 in Production Processes

Sayahi, Zeinab January 2021 (has links)
The popularity of the term innovation is growing rapidly. Its significant role in the increasingly competitive world is not deniable. Consequently, to secure their profitable growth, enterprises across the world try to improve their innovation capabilities.After publishing the first international standard by ISO, in the realm of innovation management system, this current thesis project is performed to investigate the challenges and motivations that production units may have in implementing the new standard, ISO 56002, in their production processes. The empirical part of the project is carried out in cooperation with five Swedish industrial companies. A variety of companies regarding to the type of activities, size, age, etc. were selected. Based on the content of standard ISO 56002, the collected data from prior research and empirical findings, an analysis is performed. The results shows that organizations have different approaches toward managing innovation activities and their current innovation management’s capabilities is a determining factor for challenges with ISO 56002. However, all respondents have positive attitude toward the implementation of ISO 56002 in the production processes and consider it as a useful standard with many potential benefits for their organizations. Challenges that companies may confront, in applying ISO 65002 in the production processes, are culture, involvement of leadership, immaturity in working with processes, etc. Considering the consensus about the culture as a challenge, a model to enhance the employee’s engagement is suggested.This thesis is one of the pioneers in investigating the applicability of ISO 56002:2019 in a production process. It can provide production units with useful information and contribute to the innovation management community.The empirical information is collected from companies that have not implemented ISO 56002.Future studies by focusing on the companies with ISO 56002, can shed light on new aspects of the standard’s applicability in the production processes and develop findings of the present thesis. Additionally, the implementation of standard’s various features in production processes can be inspected individually. Keywords:ISO 56002:2019, ISO 56000:2020, Standard, Innovation, Innovation Management System, Production Process / <p>The presentation was online through the application ZOOM.</p>

Propuesta de incremento de la capacidad de producción de masas de harina para cubrir la demanda en cadena de pizzerías / Production process improvement of a restaurant chain applying TOC and MRP

Ladines Tejada, Rodrigo, Villa Alvarado, Jaime Armando 18 October 2021 (has links)
El proceso de producción es uno de los más importantes, si no el más importante, para una organización. Para el rubro de alimentos y restaurantes, una producción eficiente y que se adapte a las diversas fluctuaciones de la demanda determinará su éxito económico como posicionamiento en el mercado. En este contexto, las áreas de Operaciones y de Marketing juegan un rol importante para el desarrollo de la rentabilidad anhelada por la compañía. Numerosos casos de estudio e investigación han demostrado que la Teoría de Restricciones, en conjunto con el seguimiento de la metodología MRP, permite una adecuada planificación de la producción. Es por ello por lo que este trabajo se apoyará en ambas herramientas de ingeniería industrial para solucionar la problemática identificada en una importante cadena peruana de restaurantes. TOC permitió identificar la restricción del proceso productivo, llegando a la conclusión que para satisfacer la demanda de pizzas sería necesario considerar la compra de nueva maquinaria (levadoras). Adicionalmente, se simularon los escenarios actual y mejorado para validar matemáticamente la propuesta que se desea implementar, por medio del software Arena. El análisis económico se validó con el software @Risk. En los límites de un escenario conservador de demanda, podría lograrse una TIR de aproximada de 57% en promedio, colocando a la propuesta planteada como viable y exitosa. / Production is one of the most important, if not the most important, process for any organization. For the food and restaurant sector, efficient production that adapts to demand fluctuations will determine its economic success, as market position. In this context, the Operations and Marketing areas play an important role in developing the desired profitability for the company. Numerous case studies and research have shown that the Theory of Constraints and MRP methodology, allow adequate production planning. For this reason, this paper will rely on both industrial engineering tools to solve the problems identified in an important and major Peruvian restaurant chain. TOC identified the restriction of the production process, reaching the conclusion that to satisfy the demand for pizzas it would be necessary to consider the purchase of new machinery (lifters). Additionally, the current and improved scenarios were simulated to mathematically validate the proposal to be implemented, using the Arena software. The economic analysis was validated with @Risk software. Within the limits of a conservative demand scenario, an IRR of approximately 57% on average could be achieved, placing the proposed proposal as viable and successful. / Trabajo de Suficiencia Profesional

Ali, Amir, Ali, Aweys, Mårtensson, Fredrik January 2023 (has links)
In line with today's emergence of new technology, there is high competition within the manufacturing industry, which places higher demands on today's industries to develop new strategies to withstand the fierce competition. For this reason, today's industry needs to be more efficient and is becoming increasingly digitized, which is the core of the new industrial revolution called "industry 4.0".  The aim of this study is to investigate, with the help of value flow analysis, new innovative tools, and principles within lean production, whether the manufacturing process can be more efficient. The study was carried out at a manufacturing company that produces dehumidifiers and has ambitions to streamline it’s manufacturing process.  Through the literature review, site observations, interviews and data analysis, a comparison was made with the theory to find solutions to the problems that emerged. The results of this study show that it is theoretically possible to make a manufacturing process more efficient using these methods. It can be pointed out that one important study will be to test these solutions to see what results can be achieved. / I linje med dagens framväxt av ny teknik råder det hög konkurrens inom tillverkningsindustrin, vilket ställer högre krav på dagens industrier att utveckla nya strategier för att stå emot den hårda konkurrensen. Av den anledningen måste dagens industri bli mer effektiv och digitaliseras alltmer, vilket är kärnan i den nya industriella revolutionen som kallas "industri 4.0".  Syftet med denna studie är att med hjälp av värdeflödesanalys, nya innovativa verktyg och principer inom lean production undersöka om tillverkningsprocessen kan bli mer effektiv. Studien genomfördes på ett tillverkningsföretag som producerar avfuktare och som har ambitioner att effektivisera sin tillverkningsprocess.  Genom litteraturgenomgång, platsobservationer, intervjuer och dataanalys gjordes en jämförelse med teorin för att hitta lösningar på de problem som uppstod. Resultaten av denna studie visar att det är teoretiskt möjligt att effektivisera en tillverkningsprocess med hjälp av dessa metoder. Det kan påpekas att en viktig studie kommer att vara att testa dessa lösningar för att se vilka resultat som kan uppnås.

Tala om arkitektur : Om två arkitekturorganisationers förhållande till talet, språket och behovet av utbredd kunskap inom ett samhällsbärande område / Talking about architecture : Two Swedish architecture organizations relations to talking, language and the need for a broad knowledge in a field of great social importance

Daram Westling, Lisa January 2021 (has links)
På ett övergripande plan handlar den här studien om språkets roll inom arkitektur, teoretiskt och praktiskt. Titeln Tala om arkitektur refererar till vad som händer i talad mening, mellan arkitekter, mellan arkitekter och andra yrkesgrupper och – bredare – i allmänt tal om arkitektur. Är tal om arkitektur en grund för kunskap, i kunskapsproduktion och i användandet av arkitektur, på samhällsnivå? Frågan har bäring på förutsättningar för demokrati. Studien bör ses som en ambition att resa frågor om språk och arkitektur, för att lägga en grund för fortsatta studier. Som bakgrund till intresset för språk finns tankar kring arkitekturens status i samtiden, kopplat till klimatfrågor och social hållbarhet. Vet vi tillräckligt för att skapa byggd miljö som inte skadar planeten och som bidrar till välfungerande miljöer, socialt och hälsomässigt? Vad behövs för att vi ska få tillräcklig kunskap? Studiens konkreta fråga är hur två arkitekturorganisationer i Sverige – Stiftelsen Arkus (åren 1986–2018) och den statliga kommittén Rådet för arkitektur, form och design (åren 2004–2008) – har uppmärksammat språk om arkitektur som ett särskilt kunskapsområde, i egen rätt. Uppdragen för båda organisationerna har, på olika sätt, varit och är fortfarande för Arkus del, kunskapsproducerande.  Det empiriska materialet I studien består av allmänt tillgängliga skrifter, rapporter och styrdokument. En problembild är tecknad med utgångspunkt i tidningsartiklar, myndighetsrapporter och facklitteratur. Den pekar mot en problematisk, samtida situation gällande brister vad gäller tillämpning av kunskap om arkitektur, vid planering och byggande. Problembilden omfattar också brister i den allmänna kunskapsnivån som bildar bas för en allmän diskussion i samhället, om arkitektur och byggd miljö. Resultatet av undersökningen är att tal och språk har uppmärksammats i både Arkus och Rådet för arkitektur, form och design, men temat har inte lyfts i egen rätt som ett kunskapsområde som behöver fortsatta undersökningar. Språkfrågan – att tala, läsa, skriva, reflektera samt även att skapa kontakt med omvärlden, har snarare förts fram av enstaka eldsjälar med ett starkt intresse. Kommentarer om språkets betydelse har då och då framförts på ett tydligt sätt, av utomstående. Studien är långt ifrån en fullödig bild. Den visar utdrag från en begränsad situation inom ett tidsspann av närmare 40 år. Syftet med studien är att resa frågan om språkets roll inom arkitekturfältet, samt att belysa hur detta tema har hanterats av två svenska arkitekturorganisationer med kunskapsspridande uppdrag. Studien är på svenska. / On a larger scale this study is about the role of language within architecture – in theory and in practice. The title Talking about architecture is referring to what is happening, in a spoken sense, between architects, between architects and other professions in planning, building and property management, and broader – how the public speaks about architecture, and how this is linked to knowledge. Is the talking about architecture the root of knowledge, in production and in the use of architecture/built environment on a societal level? The study is set in Sweden and should be seen as an ambition to raise questions about language and architecture to prepare for further investigations. As a background to the interest in language lies a concern for the status of architecture and built environment, connected to climate and social sustainability. Do we know enough to shape built environment that is not harming the planet, but contributes to well-functioning communities, socially and health-wise? What is needed to know enough? The study’s central question is how two important architecture organizations in Sweden – The Arkus foundation (1986–2018) and The National Council for Architecture, Form and Design (2004–2008) – have put their attention to language as a specific topic, to be addressed in its own right. The task for both organizations, even in different ways, was the production of knowledge within the field of architecture. Besides the language topic, an important aim connected to the study, was to make knowledge about these two organizations available, since little is known about their work outside the organizations themselves.  The method for analyzing the documentation originating from the organizations was qualitative. The empirical material in the study consisted of white papers and research reports. A few open interview-like conversations have also been made. A background is depicted in the study, retrieved from articles and reports. It is reflecting on a problematic contemporary situation concerning a lack of applied knowledge in production processes for architecture and the built environment. It also points out a shortcoming in the contemporary public discussion about architecture and the built environment, due to a frail knowledge base for these topics. The study concludes that the language topic was addressed in both Arkus and The National Council for Architecture, Form and Design. However, language and communication, among architects and with the world around, was not raised as a central issue in need of being further investigated. The language topic – talking, reading, writing, reflecting and also reaching out – was rather brought forward by a few persons in the organizations with a strong interest, or by outsiders.  This study does not give a full picture, but it highlights different events on architectural language within a timespan close to 40 years. It suggests that the focus on language should have been a special concern for two architectural organizations whose focus was on the practical field and on knowledge dissemination. The study is in Swedish.
