Quick Decision And Analysis Of Liquid Cargo Supply’s Project

In the process of the entire supply, the change of the ship’s liquid cargo is large, that will bring big impact to its own state. In order to make its stability, strength and the float state moderate, the captain should always have rich experience to make these decisions by referring to the manual of ship loading, ship design specification, and the whole process is time-consuming and error-prone.About the above problem, this paper introduces the ship’s stability, strength and the theory calculation formula of floating state in detail. According to real engineering research projects, the problem is turned into multi-objective optimization mathematical model. The classical methods of multi-objective optimization are expounded. In the meanwhile,multi-objective evolutionary algorithms are introduced especially particle swarm optimization algorithm. Different methods are used to solve the multi-objective optimization problem, including equal traversal thought to generate the feasible solution.Minimizing the objective function is used to find the optimal solution. TOPSIS is a method of approach ideal solution sorting algorithm, which is used to find the optimal solution.Aiming at the faults of the above methods, PSO algorithm is applied into the project and the time complexity and mathematical precision are both improved effectively.In addition,this paper summarizes the design concepts of maritime cargo resupply. The liquid cargo supply software is researched and developed using Visual Studio 2010. At last it is proved to be effective in practical engineering project inspection. The software makes the liquid cargo supply more intelligent and more automatic.
