N owadays PT Indonesia Toray Synthetics (ITS) is facing problems in the good product storage layout. To store Nylon Filament Yarn (NFY), this company has two separated storage, and at each storage there are areas of the good products with only one aisle. The positions of the good products with the distance between the pallets is unwell organized and the pallet is stacks that are limited. So that it needs another area to place to excessive pallets. The position of the pallets that are unwell organized, has caused some difficulties the storage and retrieval of the good products. To retrieve in the good products which are placed on the deepest position of the pallet stacks, the operator has to remove the front pallets and it takes quite long time to re-arrange the pallets. To maximize the space utilization, the operator has to pile up the pallets more than the capacity. Beside that, the management of the store good products data areas still manual, so that is causes misinformation about the good products inventory and flow at the storage.The problem that has decreased the efficiency of storage. The problem can be solved by two ways such as doing re-layout and creating a new computerized system of storage. Before making suggestion, it needs the maximum mount of the stored good products in the future by doing forecasting. The forecasting of the good products has tobe done according to the historical data. Some of the forecasting methods which are use here area Single Moving Average (SMA) (2x2) and (7x7), Single Exponential Smoothing (SES) (a=0,2) and (a=O,7), seasonal and cyclical. Then calculate the errors of the good products by comparing the smallest errors of all. From those errors the maximum need of the pallet can be found. There are several steps for making suggestion of storage layout. To simplify the arrangement of good product from two separated storages into one storage, so the suggestion of good product from to separated shelf which is considering the dimension of pallet and box can be designed, then the number of shelf can be found. After that making design the arrangement of shelf by using Dedicated Storage Method, Fuzzy Subtractive Clustering Method, and Cube per Order Index Method . Than the best layout can be chosen based on the smallest value of Material Handling Evaluation Sheet (MHES) . The chosen design of storage layot for PT. Indonesia Toray Synthetics (ITS) in Nylon Filament Yarn (NFY) department which has been calculated by Fuzzy Subtractive Clustering Method is equal to Rp 7.664.931.96 that is the smallest MHES .Afterwards, computerized storage system is designed to simplify storage and retrieval of good product . This system consist of the information of shelf position for each good and the number of good inventory, and also the document of shipping andreceiving good.
