An adaptive algorithm of PDA location commodity out-store

1. Function description
2. Code implementation
3. Algorithm requirements

Back to top function description on the PDA, by scanning the order number, query the item number, size, number of orders, as well as the warehouse location commodity "SKU", showing the location of the product, inventory quantity, the number of matching.   Because the PDA interface is small, the table split is displayed as two, and the code is correspondingly more complex.

Back to top algorithm requirements(1) Order number >= The sum of the stock number is the appropriate number = inventory number;

  (2) Number of orders < Total number  of items in stock = allocation of number of any location (must = number of orders)

(3) The location of large inventory priority adaptation; an equal number of location, a small location number of priority adaptation strategy
