Fallstudie om Prediktivt och Tillståndsbaserat Underhåll inom Läkemedelsindustrin / Case study regarding Predictive and Condition-based Maintenance in the Pharmaceutical Industry

Redzovic, Numan, Malki, Anton January 2022 (has links)
Underhåll är en aktivitet som varje produktion vill undvika så mycket som möjligt på grund av kostnaderna och tiden som anknyts till den. Trots detta så är en väl fungerande underhållsverksamhet väsentlig för att främja produktionens funktionssäkerhet och tillgänglighet att tillverka. En effektiv underhållsorganisation går däremot inte ut på att genomföra mer underhåll än vad som egentligen är nödvändigt utan att genomföra underhåll i rätt tid. På traditionellt sätt så genomförs detta genom att ersätta slitage delar och serva utrustningen med fastställda mellanrum för att förebygga att haveri, vilket kallas för förebyggande underhåll. De tidsintervaller som angivits för service bestäms av leverantörerna och grundar sig i en generell uppskattning av slitagedelarnas livslängd utifrån tester och analys. Till skillnad från att köra utrustningen till den går sönder som kallas för Avhjälpande underhåll så kan underhåll genomföras vid lämpliga tider så att det inte påverkar produktion och tillgänglighet. Men de tidsintervall som leverantörerna rekommenderar till företagen garanterar inte att slitage delen håller sig till det intervallet, delarna kan exempelvis rasa tidigare än angivet eller till och med hålla längre. Av denna anledning är det naturliga steget i underhållets utveckling att kunna övervaka utrustningens hälsa i hopp om att kunna förutspå när och varför ett haveri ska uppstå. Den här typen av underhåll kallas för tillståndsbaserat och prediktivt underhåll och medför ultimat tillgänglighet av utrustning och den mest kostnadseffektiva underhållsorganisationen, då god framförhållning och översikt uppnås för att enbart genomföra underhåll när det behövs. Det som gör tillståndsbaserat och prediktivt underhåll möjligt är den fjärde industriella revolutionen “Industri 4.0” och teknologierna som associeras med den som går ut på absolut digitalisering av produktionen och smarta fabriker. Teknologier som IoT, Big Dataanalys och Artificiell Intelligens används för att koppla upp utrustning till nätet med hjälp av givare för att samla in och lagra data som ska användas i analyser för att prognosera dess livslängd. Uppdragsgivaren AstraZeneca i Södertälje tillverkar olika typer av läkemedel som många är livsviktiga för de patienter som tar dessa mediciner. Om AstraZenecas produktion står still på grund av fel i utrustningen kommer det inte enbart medföra stora ekonomiska konsekvenser utan även påverka de människor som med livet förlitar sig på den medicin som levereras. För att försäkra produktionens tillgänglighet har AstraZeneca gjort försök att tillämpa tillståndsbaserat och prediktivt underhåll men det är fortfarande enbart i startgroparna. Eftersom ventilation är kritisk del av AstraZeneca produktion då ett fel i ventilationssystemet resulterar i totalt produktionsstopp i byggnaden förens problemet åtgärdas och anläggningen sanerats blev det även rapportens fokusområde. Arbetets uppgift går därför ut på att undersöka möjligheter för AstraZeneca att utveckla deras prediktiva och tillståndsbaserat underhåll på deras ventilationssystem, för att sedan kunna identifiera och presentera förslag på åtgärder. Dessa förslag analyserades sedan med hjälp av verktygen QFD-Matris och Pugh-Matris för att kunna uppskatta vilket förslag som är mest kostnadseffektivt, funktions effektivt samt vilket förslag som kommer tillföra mest nytta för underhållet på AstraZeneca. / Maintenance is an activity that every production wants to avoid as much as possible due to the costs and the time associated with it. Despite this, a well-functioning maintenance operation is essential to promote the production's availability to manufacture and operational reliability. Running an efficient maintenance operation is not about carrying out more maintenance than is necessary but carrying out the right amount of maintenance at the right time. Traditionally speaking this is done by replacing worn parts and servicing the equipment at set intervals to prevent breakdowns, this method is called preventive maintenance. The intervals specified for service are determined by the suppliers and are based on general estimates of the service life for the spare parts from test and analytics. Preventive maintenance allows for maintenance to be carried out at appropriate time to not affect production and availability unlike running the equipment until breakdown, which is called reactive maintenance. However, these intervals that the suppliers recommend do not guarantee that the parts adhere to the given interval, the part can for example break down earlier than expected or even outlast its prescribed lifetime. Because of this, the natural step in the development of maintenance is giving companies the ability to monitor the health of the equipment in hope of being able to predict potential breakdowns. This is what Condition-Based and predictive maintenance is and it provides the ultimate availability of equipment and the most cost-effective maintenance organization, because the good foresight and overview allows maintenance to be carried out only when needed. The fourth industrial revolution “Industry 4.0”, absolute digitalization of production, smart factories and all the technologies associated with this is what makes this type of maintenance possible. Technologies such as IoT, Big Data Analytics and Artificial Intelligence are used to connect equipment to the network using sensors so that data can be stored and collected to be analyzed to forecast the lifespan of parts and equipment. AstraZeneca in Södertälje manufactures different types of medicine, many of which are vital for the patients who take them. If their production comes to a standstill due to equipment failure, it will not only have major financial consequences but also greatly affect the people who rely on the medicine offered with their lives. To ensure the availability of production, AstraZeneca has made attempts to apply condition-based and predictive maintenance, but it is still only in its infancy. Since ventilation is a critical part of AstraZeneca's production, as a failure here will result in a total production stoppage for the building affected and will not resume before the problem is remedied and the plant is decontaminated, it also became the report's focus area. The task at hand is therefore to investigate the opportunities AstraZeneca must develop their predictive and condition-based maintenance for their ventilation systems, in order to be able to present proposals for measures. The proposals will then be analyzed using tools like the QFD-Matrix and the Pugh-Matrix in order to estimate which is more cost effective, function effective and which one will bring the most benefit to AstraZeneca.

Forecasting the Present / A Media-archaeo-genealogical Inquiry into Project Cybersyn

Gómez Venegas, Diego Ignacio 14 August 2024 (has links)
Diese Arbeit versucht, die techno-epistemologischen Grundlagen des Projekts Cybersyn zu entschlüsseln. Durch die Rekonstruktion des technologischen Archivs wird zum ersten Mal ein detaillierter Bericht über die technologischen Ereignisse vorgelegt, die dieses Projekt in Gang setzten. Als Versuch, die chilenische Industriewirtschaft nach den Theorien der Management-Kybernetik zu steuern, gilt das Projekt Cybersyn als eines der innovativsten technologischen Unternehmungen der frühen 1970er Jahre. Da es im Kontext der Regierung Allende und der sozialistischen Revolution in Chile entwickelt wurde, ist das Projekt in der Regel als ein Produkt eines solchen Prozesses interpretiert worden. Diese Arbeit fragt jedoch, ob ein solches Verständnis nicht eine umfassendere Bewertung des Projekts und seiner Tragweite behindert. Daher wird in dieser Dissertation das technologische Archiv von Project Cybersyn untersucht, um zu klären, ob dieser Fall möglicherweise eine frühe Konkretisierung einer Techno-Episteme war, die wiederum einen epochalen Wandel signalisierte, in den unsere Gegenwart noch immer eingeschrieben ist. Mit Blick auf Wolfgang Ernsts Begriff der Agentur der Maschine zeigt diese Arbeit, dass sich in der operativen Konfiguration des Project Cybersyn klare technologische Prinzipien erkennen lassen, die nicht nur neue Modi für die Konfiguration und Zirkulation von Informationen vorschreiben, sondern auch für die Organisation und Interaktion zwischen maschinellen und menschlichen Agenturen. In diesem Sinne zeigt diese Dissertation, dass das technologische Archiv des Project Cybersyn das Entstehen einer Techno-Episteme und einer Techno-Politik signalisiert. Schließlich zeigt diese Arbeit, dass bei der Umsetzung von Project Cybersyn eine Reihe von technologischen Ereignissen einem allgemeinen Prozess des kollektiven Werdens weichen musste. Mit anderen Worten, diese Studie über das Projekt Cybersyn zeigt, dass dieser Fall als eine Vorhersage der Gegenwart funktioniert. / This research seeks to unravel the techno-epistemological principles underlying Project Cybersyn. By reconstructing its technological archive, this study presents for the first time a detailed account of the technological events that set this project in motion. As an effort to control Chile's industrial economy under the theories of management cybernetics, Project Cybersyn is considered one of the most innovative technological undertakings of the early 1970s. Developed in the context of the Allende government and the socialist revolution in Chile, the project has usually been understood as a product of such a process. This research asks, however, whether such an understanding may hinder a more comprehensive assessment of the project and its scope. Accordingly, this dissertation examines the technological archive of Project Cybersyn in order to elucidate whether this case may have been an early concretization of a techno-episteme that, in turn, signaled an epochal shift in which our present is still inscribed. With attention to Wolfgang Ernst’s notion of the agency of the machine, this research shows that in the operational configuration of Project Cybersyn, clear technological principles can be discerned; principles that prescribe not only new modes for the configuration and circulation of information, but also for the organization and interaction between machine and human agencies. In this sense, this dissertation demonstrates that the technological archive of Project Cybersyn signals the emergence of both a techno-episteme and a techno-politics. Finally, this research shows that in the implementation of Project Cybersyn, a series of technological events gave way to a general process of collective becoming. In other words, this study of Project Cybersyn shows that this case operates as a forecast of the present.

Integration of UAVS with Real Time Operating Systems and Establishing a Secure Data Transmission

NIRANJAN RAVI (7013471) 16 October 2019 (has links)
In today’s world, the applications of Unmanned Aerial Vehicle (UAV) systems are leaping by extending their scope from military applications on to commercial and medical sectors as well. Owing to this commercialization, the need to append external hardware with UAV systems becomes inevitable. This external hardware could aid in enabling wireless data transfer between the UAV system and remote Wireless Sensor Networks (WSN) using low powered architecture like Thread, BLE (Bluetooth Low Energy). The data is being transmitted from the flight controller to the ground control station using a MAVlink (Micro Air Vehicle Link) protocol. But this radio transmission method is not secure, which may lead to data leakage problems. The ideal aim of this research is to address the issues of integrating different hardware with the flight controller of the UAV system using a light-weight protocol called UAVCAN (Unmanned Aerial Vehicle Controller Area Network). This would result in reduced wiring and would harness the problem of integrating multiple systems to UAV. At the same time, data security is addressed by deploying an encryption chip into the UAV system to encrypt the data transfer using ECC (Elliptic curve cryptography) and transmitting it to cloud platforms instead of radio transmission.

Mobiliųjų paslaugų portalų technologijų tyrimas / Research of mobile portals technologies

Najulis, Mindaugas 03 June 2005 (has links)
Information technologies and mobile telecommunications rapidly enter our personal and social life. Mobile phone is no longer luxury – it has become a necessity. Growing volumes of the mobile services has caused a need to expand the mobile service employment opportunities in the Internet portals. Today’s portals, created using the means, offered by software manufacturers, employ exclusively the mobile Internet service, thanks to which the users can see and manage the necessary information and process of the portal at any time and from anywhere. The problem is related with the fact that mobile Internet services are still expensive in Lithuania. Therefore one should look for cheaper ways to reach and manage portal information. In order to solve this problem one can consider the SMS and MMS message sending, suggested by mobile technologies. Basic aim of the work is to create an entertainment portal, rendering the user both various Internet entertainments (e.g. Internet acquaintances, games), and mobile entertainment (e.g. sending messages, logos, melodies, animations and games for mobile phone) as well as a wide range of mobile services to be used to obtain and to manage the portal information. In the work I describe: portal evolution, classification and creation measures („BroadVision Portal“, „IBM WebSphere Portal for Multiplatforms v5.x“, „Sun One Portal Server v6.0“, „Red Hat Enterprise Portal Server“, „Microsoft SharePoint® Portal Server 2003“, „ORACLE 9ias Portal“, „PHP:...

Překlad z češtiny do angličtiny / Czech-English Translation

Petrželka, Jiří January 2010 (has links)
Tato diplomová práce popisuje principy statistického strojového překladu a demonstruje, jak sestavit systém pro statistický strojový překlad Moses. V přípravné fázi jsou prozkoumány volně dostupné bilingvní česko-anglické korpusy. Empirická analýza časové náročnosti vícevláknových nástrojů pro zarovnání slov demonstruje, že MGIZA++ může dosáhnout až pětinásobného zrychlení, zatímco PGIZA++ až osminásobného zrychlení (v porovnání s GIZA++). Jsou otestovány tři způsoby morfologického pre-processingu českých trénovacích dat za použití jednoduchých nefaktorových modelů. Zatímco jednoduchá lemmatizace může snížit BLEU, sofistikovanější přístupy většinou BLEU zvyšují. Positivní efekty morfologického pre-processingu se vytrácejí s růstem velikosti korpusu. Vztah mezi dalšími charakteristikami korpusu (velikost, žánr, další data) a výsledným BLEU je empiricky měřen. Koncový systém je natrénován na korpusu CzEng 0.9 a vyhodnocen na testovacím vzorku z workshopu WMT 2010.

資訊科技公司產業解決方案之策略研究 - 以IBM公司之「智慧的地球」計劃與其產業解決方案策略為例 / The industrial solution strategy research for IT companies - IBM`s「Smarter Planet」initiative and solution strategy as the case study

馬紹宏, Ma, Andy Unknown Date (has links)
本論文從IBM在軟體的策略,尤其是軟體的產業解決方案作為研究的核心。2008年的金融海嘯造成全球經濟大衰退,IBM適時提出了智慧的地球的計劃與願景,並積極推動從客戶實際需求與價值思考出發的產業解決方案(Industrial Solution),結果IBM驗證了其營運與業績不但沒有受到影響並且在營收與獲利上繼續穩健成長。本論文首先依時間軸對IBM自1993年葛士納總裁接任後針對服務與創新的轉型;到2003年帕米沙諾接班後的併購計劃與智慧的地球創新策略;乃至於2012年羅美蒂繼任後推動之商業分析,軟體產業解決方案以及最重要的2015年成長計劃等各項重要改革與執行策略做一詳細的整理與分析,個案研究針對IBM公司所面臨的挑戰與企業經營策略及轉型架構進行分析與探討並延伸至軟體產業解決方案,以Michael Porter的五力分析架構對IBM公司在軟體產業與產業解決方案的產業競爭態勢予以深入探討分析,並針對IBM與其主要競爭對手的軟體產業解決方案以SWOT做一完整的分析,此外也從IBM的軟體事業群的成長與轉型策略,來驗證IBM對軟體的產業解決方案的重視與策略意涵,並針對軟體之產業架構(Industry Framework)的發展與導入的「客戶導向與客製化產業解決方案開發策略(client focused & tailored execution strategy)」與成功要素予以分析並歸納。 最後結論中對國內軟體產業以Michael Porter的鑽石模型做一分析,並對未來台灣軟體產業可能的發展方向提出建議以提供產業與政策制定者參考,如何面對與開發國際市場以及如何從人才面發展並建立台灣的軟體產業競爭優勢將是值得我們仔細深入思考的方向,希望未來台灣的軟體產業也能創造出典範移轉,發展出如同IC設計與製造產業的規模與競爭優勢。 / The development of this paper is focused on IBM`s software strategy,especially on the strategy of IBM`s software industrial solution as the research focuses。When the financial tsunami caused the serious economic recession around the world during 2008 year end,IBM raised the「smarter planet 」initiative and vision to drive the execution of series of industrial solution centric projects according to the client real requirements and values。IBM proved that its operation and business performance were not affected by this crisis,moreover IBM continued to grow steadily in the areas of both income and margin。In the context of this paper,I will first analyze the IBM`s transformation history in the three key stages under three CEOs,including Lou Gerstner`s service & innovation transformation since 1993;Sam Palmisano`s Merge & Acquisition plan & smarter Planet initiative;and Ginni Rometty`s 2015 roadmap plan to shoot for at least US$ 20 EPS by year 2015。 In the case study we will analyze the challenges which IBM was facing from corporate operation and transformation standpoints. For IBM`s software & software industrial solution strategy,Michael Porter’s five forces framework will be used to do an analysis to have a clear view on IBM`s competitiveness in the software & software industrial solution industry. SWOT analysis will also be applied to gain an in-depth view on IBM and its major software industrial solution competitors。From IBM software group’s growth and transformation strategy,we can also verify the strategic imperatives on IBM`s focuses on industrial solutions。Finally we use the example of how IBM successfully developed the various Industry Frameworks through client focused & tailored execution strategy to illustrate IBM`s asset-based solution development concept。From the recent organizational transformation of IBM software group in 2012,we can also prove that the transformation direction is toward solution centric。 In the summary of this paper I will analyze Taiwan`s software industry using Michael Porter’s Diamond model to come out several suggestions for the reference of software development vendors and government policy makers in Taiwan。How to develop the international market and build the talent resources to increase Taiwan`s competitiveness advantage will be the key focuses which we need to think deeply。Hopefully the software industry in Taiwan will have a paradigm shift and grow to the scale of the IC design and manufacturing industry with competitiveness。
