| Warehouse layout is one of the factors which can improve productivity of a company. For now, the condition of auxiliary material’s warehouse layout can make a honeycombing problem which can make acceptance and displacement process worse. From moving distance cummulative method, we can know the moving distance in non B3 auxiliary material’s warehouse is 478,80 metres and for B3 auxiliary material’s warehouse is 167,58 metres. For now, the placement process of auxiliary material in its warehouse was doing randomly. The moving distance for displacement process is longer because there are auxiliary materials was placing in the track for placement and honeycombing problem. So, the placement process must go through the problems. In this final project, it will give an advice for improvement of auxiliary materials’ warehouse layout which start from make a warehouse layout based of materials’ flow. So, we can optimize the rack’s quantity in auxiliary materials’ warehouse. For auxiliary materials’ placement process, in B3 auxiliary materials’ warehouse will compare two methods are dedicated storage and class based dedicated storage method. In addition, for non B3 auxiliary materials’ warehouse will compare combinations of usage-dimension-function factors and use three methods are dedicated storage, class based dedicated storage, and randomized storage method. In B3 auxiliary materials’ warehouse, the best method is class based dedicated method which can minimalize the moving distance for 12,27 % that make the distance becomes 147,02 metres and can optimize the rack’s quantitiy for 18,18% that make the rack’s quantity becomes 39 racks. For B3 auxiliary materials’ warehouse, the best method is combination of usage-dimension-function factors with dedicated storage method which can minimalize the movng distance for 14,38 % that make the distance becomes 409,93 metres and can optimize the rack’s quantity for 18,07% that make rack’s quantity becomes 98 racks which divided into two levels. |
