Kartläggning av truckflöden på Primary Products : Ur ett Lean Production perspektiv

<p>The Transport division is responsible for the internal transports on Sandvik Material</p><p>Technology AB. At the moment there is no clear picture of how the straddle carriers are</p><p>moving at the division Primary Products and if it is working in a satisfying way. It is</p><p>important to see the whole picture of the transportation flow so improvements can be made.</p><p>The purpose of this essay is to survey and analyse the truck flow in a Lean Production</p><p>perspective. The essay is delimited to only include straddle carriers transportation ways in the</p><p>Primary Products division. To survey the truck flow we have used a method called Walkthrough.</p><p>This means that we have walked thorough the whole production flow and</p><p>interviewed some of the employed on the way to get the necessary information. We have also</p><p>made an extensive literature study to gather all the necessary theories that is relevant for this</p><p>essay.</p><p>Since 2003 Sandvik Material Technology is running a project called “ledtidsprojektet”, the</p><p>purpose of this project is to create a more efficient production. This project is based on the</p><p>Japanese philosophy Lean Production but is audited to be suitable to Sandviks organisation.</p><p>Today most of the producing divisions within SMT are working according to</p><p>”ledtidsprogrammet”, unfortunately it is not introduced on the Transport division yet.</p><p>The result we got by studying the use of the straddle carriers showed that 40 % where with</p><p>cargo, 35 % without and 25 % where remaining times were breaks are included. The basis of</p><p>the study is from a GPS-transmitter which is placed on one of the straddle carrier. We have</p><p>also made our own study where we followed on the straddle carrier and measured the time for</p><p>the different activities. To get a more statistical secured investigation it is necessary to make a</p><p>more extensive study, when these study where made during a limited time.</p><p>On the basis of the truck flows survey some suggestions for improvements have been</p><p>identified. It has showed that today’s key measurements have to be overlooked to give a fair</p><p>picture of the situation. They also have to improve the way they are planning the transports.</p><p>This can be made by better communication with the producing divisions.</p><p>For the straddle carriers to be more Lean first the producing divisions have to work according</p><p>to the Lean philosophy. It is up to them to try to reduce the stock level and get a more evenly</p><p>production.</p>
