According to the locations of in or out entrance, the RGV could be sorted two kind of model, first in first out(FIFO) and last in first out(LIFO). FIFO: The pallets loading entrance in one side, and taking out in other side Advantages: To achieve the order of logistics access, meeting the general requirements of logistics To realize logistics access division operation, improving on the spot management. Disadvantages: Must be arranged forklift channels in two side of the RSCRS,the usage rates of dynamic storage is lower than the LIFO model LIFO: Pallets loading in or taking out all in one side of RSCRS, and arranging one forklift channel only one side Advantages: To arrange one forklift channel only one side, and utilizing the storage area maximally To fulfill the situation which undemanding the specified order of seniority. Disadvantages: Can not achieve the specified order of pallets
