Warehousing Functions and Objectives
February 3, 2007The basic warehousing functions traditionally have been considered to be as follows (Tompkins and White, 1984):
- receiving;
- identification and sorting;
- dispatching to storage;
- placing in storage;
- storage;
- retrieval from storage;
- order accumulation;
- packing;
- shipping
- record keeping.
In designing warehousing systems it is desirable to maximize (Tompkins et al. (1996):
- space utilization;
- equipment utilization;
- labor utilization;
- accessibility of all materials;
- protection of all materials.
Storing goods in adequate space with the proper equipment by well trained personnel in a properly planned layout results in maximum protection of items.
