Calculating the most efficient location of logistic distribution centers for one project in China

A logistic distribution center for a set of products is a warehouse or other specialized building, often with refrigeration or air conditioning, which is stocked with products (goods) to be redistributed to retailers, to wholesalers, or directly to consumers. A distribution center is a principal part, the order processing element, of the entire order fulfillment process. Distribution centers are usually thought of as being demand driven. A distribution center can also be called a warehouse, a DC, a fulfillment center, a cross-dock facility, a bulk break center, and a package handling center. The name by which the distribution center is known is commonly based on the purpose of the operation. For example, a retail distribution center normally distributes goods to retail stores, an order fulfillment center commonly distributes goods directly to consumers, and a cross-dock facility stores little or no product but distributes goods to other destinations.
