Improvement of storage system upright piano cabinet using class based storage

Abstract

Abstract The objective of this research is to reduce the process distance on storage and retrieval (S/R) by suggesting storage system of piano’s cabinets (piano’s parts) on the certain storage shelf. The object of the research is department of setting cabinet that obligated to bridge and organize cabinet’s supply from department of painting to department of assembly. Based on the planning and actual delivery of piano cabinets to department of assembly, it is found that only 33,3% deliveries were accomplished as recorded by data on April 2018. One of the causes is internal handling problem at the department of cabinet setting that takes longer time due to unorganized cabinet storage. After all data of “in-out stock” are resumed, later it will be processed by employing class-based storage method for material’s grouping. The data indicated that cabinet with material class A is dominated by top 4 requested models of piano and the comparison between initial storage system layout and the proposed one shows the difference on total distance of retrieval activities for 210 kilometers during 5 months of working. It could be concluded that the purpose of storage system could reduce the retrieval distance by 68%.
