Abstract [en]

Over the years the global competition has increased among companies. Companies need to know their competitive priorities to survive. Decisions about facility layout will transform a company`s competitive priorities, processes, and capacity into an actual physical arrangements of people, equipment and space. Volvo trucks in Umeå deliver today the truck cab without the front lid but when the front lid and the truck cab are painted in two different places there may be a different tint. This tint difference is eliminated when the truck cab and the front lid are painted together. When Volvo trucks in Umeå started to paint those parts together they will assembly the front lid on the cab before deliver. When they start assembly the front lid in Umeå they need to create a new factory layout to have the same efficiency as before. Two different solutions have been evaluated and compared were the front lid can be placed into a transport rack. One of those places is the workstation called the Pi-station, which is the first workstation on assembly department, and the other is on the first workstation on the ninth segment. Those two alternatives have been compared with respect to how large area that is needed for the inventory of the front lid and how much resources that are required to transport the front lid racks. The lead time for transportation of the front lid has been calculated for two cycle times and two different cases. These cases are based on where the truck driver is in the facility when he/she gets the signal to deliver a front lid rack. One of the alternatives were the front lid can be placed into a transport racks are segment nine. To transport the front lid with the cab to segment nine they need to move the assembly of the back window from segment three to Pi-station. To know if there is a chance to transport the front lid on the back of cab two simulations was made. One simulation was made in Visual Basic and the other in Matlab. The result of those simulations was mean time, shortage from buffer, total time of shortage and time of shortage. Information has been gathered through visual studies on the assembly department and historic data has been gathered from Volvo trucks databases. The information that had to be collected through visual studies could not be found in the databases. This information was used in the Matlab simulation. The result of transporting the front lid on the back of the truck cab instead of using trucks are that the inventory area of front lids can be decreased by 20 square meters and the time for transporting the front lid form the Pi-station to the subassembly station can be decreased by 10 %. The risk will also decrease that the front lid will be assembled on the wrong track cab.
