Improving Efficiency of a Process in Warehouse with RFID: A Case Study of Consumer Product Manufacturer

This warehouse has two main problems: long cycle time of receiving process and poor accuracy of inventory location. Therefore, the objective of this research is to improve the process in the warehouse by using radio frequency identification (RFID) technology. There are four steps in this research. First of all, the current of the receiving process is studied. Second is to give the guideline for RFID application. Third is to implement of RFID in this warehouse. The last one is to compare the result of the current process and the proposed process. The passive ultra high frequency (UHF) RFID is selected for used in this warehouse. The RFID readers are attached on forklift trucks, the warehouse entrance and loading dock area. The system used RFID tags in two forms: one used to identify pallets and another to indicate the locations of shelves on which pallets are stored. After using RFID in receiving process, the results showed that the cycle time decreases from 66 min to 47 min which is down to 28.79 %. Moreover, accuracy of inventory location increased from 72.8 % to 100 %.
