Analysis of the Automation and the Human Worker, Connection between the Levels of Automation and Different Automation Concepts

Mishev, Grigor January 2006 (has links)
<p>Manufacturing is becoming a crucial part of now-a-days fast growing economies and increase of earth’s population. Recently manufacturing is changing rapidly, different manufacturing strategies are being implemented, the conceptual understanding for manufacturing is changed, and new ways of producing products are showing up. Automation has been the essential term regarding the modern manufacturing processes. The humanmachine sharing is playing a major role in the production systems, and the most elegant thing is to create and design the appropriate level for interaction between them depending on the desired outcome in the production area. Technological innovation is the implementation of new more efficient production method by achieving qualitative improvements of the goods and services in a specific area in this paper’s case is a production system. This paper is regarding the importance of the correct production system being chosen for an organization regarding the right level of automation (LoA) being used, which is a way of controlling the overall effectiveness of the system.  Different approaches and methods are going to be used for demonstrating the choice of  the exact and right level of automation and the possibility of changing it by introducing and implementing the ongoing DYNAMO research on a different conceptual solutions for a foundry application in Factory-in-a-Box. The main objective of the research is to develop a method and system for supporting sustainable flexible and reconfigurable production system providing competitive industrial characteristics in the fast developing world.</p> / ProViking, Factory-in-a-box, Dynamo

Analys av klimatpåverkan och lokaliseringsbeslut för en Factory-In-A-Box produktionsanläggning / Analysis of climate impact and location decision for a Factory-In-A-Box production facility

Ding, Yiming Alex, Qian, Liuyu January 2023 (has links)
Syftet med denna studie var att analysera lokaliseringsbeslut för en Factory-In-A-Box (FIAB) produktionsanläggning med fokus på dess klimatpåverkan genom användning av livscykelanalys (LCA). En FIAB produktionsanläggning användes som ett exempel för att utföra analysen. Metoden som användes för att bedöma klimatpåverkan var LCA, där kategorin global uppvärmningspotential (GWP) valdes som den primära indikatorn. Materialen som användes för tillverkning av personlig skyddsutrustning, såsom polyeten (PE), polyetentereftalat (PET), polypropen (PP), polyuretan (PUR) och syntetiskt gummi, analyserades. Dessutom studerades energianvändningen i produktionsanläggningen samt avfallshanteringsstrategier i både Turkiet och Sverige. Anledningen till det var att den utvalda Factory-In-A-Box fabriken hade sitt ursprung i Sverige, och Turkiet identifierades som en plats med avsevärd potential för produktion av enkla produkter som skulle kunna tillverkas med hjälp av FIAB-anläggningen i händelse av nödsituationer. Resultaten av detta arbete visade att mer än hälften av utsläpp av de personliga skyddsutrustningar som producerades av FIAB-fabriken av EQpack AB kom från material som hade använts i tillverkning och att användningen av återvunnet material borde prioriteras, då utsläppen av återvunnen polyeten var endast hälften så stora som utsläppen från primära material. Resultaten visade också att det inte fanns någon klimatmässig nackdel med att omlokalisera FIAB-fabriken till Turkiet, eftersom energianvändningen i Turkiet skulle medföra endast 4.4% ökning av emissionen än att producera varorna i Sverige, vilken jämnades ut med transport av varor från Sverige till Turkiet. Dock identifierades andra aspekter som behövde beaktas vid omlokalisering av en FIAB-fabrik till områden som hade drabbats av kris, till exempel krig eller jordbävningar. Sammanfattningsvis gav denna studie insikter om klimatpåverkan av EQpack AB:spersonliga skyddsutrustning och diskuterade olika aspekter som behöver övervägas vid beslut om lokalisering av en FIAB-produktionsanläggning. / This thesis describes a study aimed at analyzing the location decision for a Factory-In-A-Box (FIAB) production facility in terms of its climate impact using life cycle assessment (LCA). A FIAB production facility was used as a case study to conduct the analysis. LCA was employed to assess the climate impact, with global warming potential (GWP) chosen as the primary indicator. The materials used for manufacturing personal protective equipment, such as polyethylene (PE), polyethyleneterephthalate (PET), polypropylene (PP), polyurethane (PUR), and synthetic rubber, were analyzed. Additionally, the energy use in the production facility and waste management strategies in both Turkey and Sweden were examined. The reason to this was that Sweden is a baseline FIAB location and Turkey was chosen as one of the locations with high potential for simple products that can be produced using the FIAB-facility for emergency situations. This study showed that more than half of the emissions derived from the production of Personal Protective Equipment at the FIAB-factory, operated by EQpack AB, originated from the manufacturing materials. The results suggest prioritizing the use of recycled materials, as the emissions from recycled polyethylene were only half as large as those from primary materials. The results also revealed that, from a climate perspective, there was no obvious disadvantage in relocating the FIAB factory to Turkey. As the energy consumption in Turkey would result in 4.4% greater environmental burdens compared to producing the goods in Sweden, which would be covered by the transport of goods from Sweden to Turkey. However, other aspects needed to be considered when relocating a FIAB factory to areas affected by crises, such as war or earthquakes. In conclusion, this study provides insights into the climate impact of EQpack AB'spersonal protective equipment and discusses various aspects to consider when making decisions regarding the localization of a FIAB production facility.
