  text: Although it is recommended to store goods in a warehouse based on the principle
    of first in first out, it is still unavoidable to use block storage of storing,
    for example, long andbulky goods. If the major advantage of block storage in area
    saving is themost important, the companyhas to accept the removal principle of
    last in first out or in other words, first in last out. The last goods to be stocked
    are the first goods to be removed and the first stocked goods are the last to
    be removed. There are some special observations in the block storage concerned
    in this paper. The first one is that the goods in the storage ordered by the customers
    can often not be removed directly from the storage without any stock movement.
    Theaim is to not only benefit fromthe high-density storage solution but also decrease
    the negative influence of block storage, especially when pre-stocked goods must
    be removed at first. The second observation is that during one concerned time
    period, forexample, one day, there may be several operations of put-away and several
    operations of order picking for shipment preparation. The third observation is
    that before goods are put away to storage, which goods to be removed are not always
    predictable. The preplanned removal dates are quite often unexpected changed.
    In this paper, scenarios with different dynamic properties and stochastic probabilities
    have been concerned and defined. Strategies for the three main stages of put-away,
    i.e. stacking, pre-marshalingand retrieval are defined and examined developed.
    Simulations have been conducted to examine the strategies based on different scenarios.
    The aimis to select the right strategy which may reduce the overall relocation
    operations. It is expected that the sum of blocks movement during put-away i.e.
    stacking, pre-marshaling, and block retrieval is optimally minimized.
