The storage and retrieval are matched processes. The quick location of any item in the stores is required to minimize the retrieval delays. It is possible only when there is definite place for keeping each item and the item is kept there. Moreover, the address of that place is conveniently defined.
A variety of stores address systems are used to address storage locations. A typical address system is shown in Figure VI. In this system, the store room is divided into blocks; each block is identified by a lateral block letter and a longitudinal block letter. Every row of shelves, within each block, is given a number. Each row is divided vertically into columns and horizontally into shelves. A particular bin is identified by a six digit, alphanumeric address code as follows:
First digit – Lateral block
Second digit – Longitudinal block next two digits – Row
Fifth digit – Column
Sixth digit – Shelf
Blocks and rows should be clearly identified with painted signs. Columns and shelves are counted from lower left corner.
Every item carried thus has a specific store location address in the form of a code, which may be written in the inventory catalogue, or a separate store location index may be prepared. The location code should not be confused with the material identification code.
