Bulk-cargo Ship Stowage Model and Algorithm for the Optimization of External Logistics

A 0/1ship stowage model was developed to optimize the stowage along with the crane scheduling,which aimed at minimizing the total loading time.The warehouse consigning capability was also considered to optimize the external logistics.Since the height and width of the bulk-cargo are restricted in the cabin according to the stowage rules,only length is need to satisfy the volume constraint,which removes the non-linear constraint by simplifying the 3D packing problem to 1D problem.The warehouse consigning time and transportation tasks are then calculated based on the beginning time of stowage of each cabin.
