product sizes and weights, these systems are designed to handle a specific range of products. Very large, small, heavy, or light products require varying degrees of manual handling.

As the process of handling involves more steps and becomes increasingly manualized, the cost increases. Storing products instead of receiving and immediately shipping them adds cost. Firms must determine when lost sales due to not having product on the shelves are balanced by increased handling and storage costs. Conversely, automating these additional manual steps can reduce the labor and costs associated with these processes. For example, automatic box-opening technology makes the process of opening individual boxes for re-packaging much faster.

Distribution center organization
All distribution centers have three main areas and may have additional specialized areas. The three main areas are the receivingand furthermore some amount of precipitation of very fine particles of material is taking place within the matrix. Once precipitated the morphology of the precipitate is altered as the heat treatment persists. Furthermore subcells are formed within the alloy. In addition to changes in relation to the precipitate there are also changes in the composition of the matrix.
The relative speeds of the various reactions alter as the temperature of heat treatment changes and furthermore vary with the time at a given temperature. This makes the prediction of the outcome of a variation in heat treatment very difficult when it is considered on a detailed and practical scale.
A subcell of the type referred to above is basically a subgrain in which there is a small difference in the angle
