Abstract
<p><strong> </strong>Refinery Unit (RU) V is a processing company owned by PT XYZ located in Balikpapan. Refinery Unit V has twelve warehouses with four warehouses being the main focus in this research of RGM, RMS, RIN, and RSP used to store products for refinery maintenance processes. In the initial conditions, there is a delay in traveling searching activities. The occurrence of delay in traveling searching activity caused by the absence of details of the product location clearly. The proposed product allocation is using Interaction Frequency Heuristic-Order Oriented Slotting method. The last step is to create a new layout for each RU V warehouse.</p><p>The first step is to calculate the cycle time for each work order list by calculating the distance between the storage point with the point of I / O based on the aisle distance calculation. Next is to compare between the cycle time of each work order list with the standard time of the warehouse, so it will know the percentage of work order list that experienced delay for one year. Next, allocate product storage based on the popularity value of the product and the value of the interaction frequency between the products. The final step is to simulate using new work order list based on the proposed allocation layout to know the effect of change from the proposed layout. The result of this research is a new layout for each warehouse. All stock taking performance are better than the standard time while the exisiting condition violate the standard time.</p>
Highlights
In the process of storing the product, Refinery Unit (RU) V Warehouse divides the warehouse into two categories, namely category S (Small) using Mezanine system and category M using single deep racking system
To identify the occurrence of delay in traveling searching activities in the warehouse PT XYZ, the steps taken is to calculate the distance using the initial condition of the layout data in the form of AutoCad
The step is to calculate the cycle time of each work order list and compare it with the standard time owned by each warehouse
Summary
In the process of storing the product, RU V Warehouse divides the warehouse into two categories, namely category S (Small) using Mezanine system and category M (medium) using single deep racking system. Judging from the problems in this research that happened at RU V warehouse PT XYZ has problem because of the happening of delay in an activity, the writer use interaction frequency heuristic-order oriented slotting method to allocate product storage to reduce the delay time on traveling searching activity. The method used in this research is Interaction Frequency Heuristic-Order Oriented Slotting method The workings of this method is first, determine the level of popularity of each SKU, determining the level of popularity of each SKU calculated using the method of COI Based on Popularity. The results of the comparison will be analyzed to prove that by doing product allocation using interaction frequency heuristic-order oriented slotting method will reduce the delay time on traveling searching activity in RU V XYZ warehouse.
