Internal material transports at Siemens Industrial Turbomachinery AB / Interna materialtransporter vid Siemens Industrial Turbomachinery AB

Gabrielsson, Petter January 2008 (has links)
This report is the result of a master thesis work which has been carried out at Siemens Industrial Turbomachinery AB (SIT). The aim of the study has been to examine the possibilities of improving the internal material handling at SIT by making the flow of materials more efficient. SIT develops, manufacture and sell steam and gas turbines to industrial customers all over the world. The site in Finspång consists of a number of workshops which are geographical spread across a fairly large area. This creates a need for material movements and transports that does not add any value to the final products being made. To examine the possibilities of making the material handling at SIT more efficient, a description of the present situation and a mapping of the internal material flows have been made. With the mapping as a starting point, a proposal for how to improve the material flow is presented and analyzed regarding both quantitative and qualitative aspects. The proposal, which is overarching and describes general effects rather than details, suggests that SIT relocate the core engine assembly department from the area called “Centrum” to the area called “Norrmalm” and locate the incoming goods area as close as possible to the place of the consumption of the material. The analysis of the mapping shows that there is 180 kilometers of internal transports at SIT every week. In this distance, transport between different departments and different working stations in the same building, are not included. The need for transports exists mainly because of the fact that SIT has its incoming goods area located at Norrmalm, approximately 2.2 kilometers away from its warehouse building and by implementing the proposal given in this work, the weekly transport distance will decrease by 60 percent. Apart from the decrease in distance, the change will also make it possible to simplify the goods receiving process.

Utredning av intermodala transporter för materialtransport inom byggbranschen / Investigation of intermodal transports for material transport in the construction industry

Väinölä, Niclas, Wong, Bengt January 2019 (has links)
Rapporten undersöker skillnaden mellan vägtransporter och intermodala transporter. Detta görs bland annat genom en totalkostnadsanalys vilket undersöker kostnader relaterade till transportprocessen och även miljöpåverkan genom utsläpp de olika transportmetoderna bidrar med och diskuterar även kringliggande faktorer som påverkar valet av transportmetod. Det visar sig att vägtransporter är det billigare alternativet men de bidrar även med mycket större miljöpåverkan än Intermodala transporter.

Effektivisering av interna materialflöden : En fallstudie på Leine &amp; Linde AB, Strängnäs

Blank, Richard January 2016 (has links)
This study is made because of the increased global competition where companies have to look in to their own business to find opportunities for improvements. The purpose of the study is to gain a deeper knowledge of the waste that occurs in internal material flow and how to improve processes like transports and material handling as part of the internal material flow.  Internal material flows in itself a waste of resources since it does not add value to the product, but the flow is necessary to make a business work. Therefore, companies should review their flows and try to find improvement to become more efficient. Unused transportation, waiting and poor material handling are just three examples of waste that was discovered during the case study. Based on the theories and data from the case study proposals for improvement have been developed.  By solving the defined questions of the study, the purpose has also been attained. More knowledge about the factors that affect the internal material flow negative and the methods you can use to enhance the flow is obtained by the study. Since only one company has studied the study can be considered limited, from a scientific perspective. / Bakgrunden till studien ligger i den ökade globala konkurrenssituationen för medelstora företag som leder till att företag måste ser om sin verksamhet för att hitta förbättringsmöjligheter. Syftet med studien är att få en fördjupad kunskap i vilka slöseri som förekommer i interna materialflöden samt hur man kan effektivisera processerna materialtransporter och materialhanteringen som ingår i det interna materialflödet.  För att kunna bemöta studiens syfte genomfördes en litteraturstudie parallellt med en fallstudie ute på ett producerande företag. Litteraturstudien startade väldigt brett med generella teorier, för att sedan gå över till att bli mer fokuserad på de delar som studien omfattar. Under fallstudien samlades kvantitativ data in genom observationer för att få fram ett resultat av nuläget hos fallföretaget. Därefter analyserades resultatet med den genomförda litteraturstudien för att på så sätt kunna besvara studiens frågeställningar och därmed syfte.  Interna materialflöden är i sig ett slöseri av resurser då det inte höjder värdet för slutprodukterna, dock är flödet nödvändiga för att få en verksamhet att fungera. Därför bör man se över sina sitt flöde och hitta ständiga förbättringar för att bli mer effektiva. Outnyttjade transporter, väntan och långa materialhanteringar var några av de slöseri som upptäcktes under fallstudien. Utifrån teorier och data från fallstudien har förbättringsförslag tagits fram, där bland annat förslag på mer strukturerade och planerade transporter kan lösa problem med outnyttjade transporter.  Genom att svara på frågeställningarna har studiens syfte uppnåtts. Då fördjupad kunskap om vilka faktorer som påverkar det interna materialflödet negativt och vilka metoder man kan använda för att förbättra flödet är erhållits genom studien. Då endast ett företag har studerats kan studien anses som begränsad ur ett vetenskapligt synsätt.  Därför kan det vara intressant att studera liknande företag i framtida studier för att se om resultaten är generaliserbara. Det skulle även vara intressant att se hur en implementering av förbättringsförslagen påverkar fallföretagets interna materialflöde.
