PT. Isuzu Astra Motor Indonesia is a company engaged in the automotive field. The purpose of this study is to optimize inventory planning so as to reduce the risk of shortage / excess pile of parts. It certainly requires some planning to determine the amount of inventory of parts that need to be prepared. In this study, the results obtained in inventory planning will be information in determining the layout of the warehouse in accordance with the conditions at hand. PT. Isuzu Astra Motor Indonesia has 423 types of parts are stored in a local warehouse small parts that have different levels of demand. Used to determine the ABC classification of inventory planning. Based on the classification obtained 78 types of parts
fast moving and slow-moving 345 units. Planning for fast moving parts inventory using inventory model Q. The results of this model is the optimal order quantity and reorder point. While the slow-moving parts using a model P. Where the output of this model is the interval during booking and expectations of demand and lead time interval reservation. In this research, the preparation of warehouse layout using dedicated storage, class - based storage, and randomized storage. Where each method has its foundations berbedasa from each other. The preparation was viewed from a perspective of parts. That is because in
the warehouse, the system is done by making parts of the goal post. Based on the results obtained with the method of preparation of the method according to the storage shed is a randomized method. Where the method is seen by parts standpoint, the goal post and the parts of the parts vendors. The preparation of getting the warehouse with an area of 794.76 m2. Results are wider than the original condition. But the number of racks used on the proposal by 8 rack units. Wide space / looseness in the barn with the method of randomized storage of 123.11 m2. The result of the proposal can be tailored to the needs of the proposed warehouse warehouse to get better again. |
