The “cargo plan”and “stowage plan”which are different and related either,are two terms in common use of shipping transportation and should be used as the nouns with different conception.

Attention being paid to the safe stowage management of dangerous cargo containers on board ships;

Stowage,securing and management of vehicles loaded onboard Ro/Ro passenger ships;

In order to provide the basis for the local strength calculation and security stowage of heavy(vehicle) Ro/Ro ships,according to the method of a simple flat panel local strength calculation,a calculating method about the local strength of heavy vehicle Ro/Ro ships is presented under operation of Ro/Ro ships,considering the effect of the hull decays and the vertical inertia force.

Fussy-optimization ES for cargo stowage;

This paper,with a view to establishing the foundation for auto-stowage expert system for container ships,based on the status quo of the stowage process and application of the technology of knowledge process to container ships,puts forward the structure mechanism for the database and repository thereof by employing the technology of knowledge reasoning.

Thus, the concept of optimization using ANN and a mathmatical model are put forward for improving cargo stowage.
