Optimization Model and Algorithm of Logistics System in Industrial Port Material Terminal Yard Based on LINGO and VB

The research is base on established material terminal yard optimization model of inventory check, inventory warning and bedding proportioning, propose a new algorithm by VB 6.0 and LINGO 9.0, which is especially suitable for the solving of nonlinear programming problem with object-oriented and visualization techniques. The connection of LINGO and VB has been researched, which makes the LINGO scripting language run directly by VB commands. Finally, the optimization model and the algorithm is proved original and effective for the proportionality of the inventory verified by the practical data acquired from an iron and steel enterprise in China.
