To solving the real-time material delivery problems during the assembly process of mechanical products, a multi-objective real-time materials distribution model was proposed considering from optimization objectives, constraints and impact factors, which integrated materials transportation costs, materials transportation time and materials storage on-line as optimization target. The calculation method of optimization objectives was given, a hybrid particle swarm algorithm was designed and the detail realization process with this algorithm was presented. Then distribution bills were gained, which used to guide materials distribution, and the overall objective optimization will be achieved, the decision-makers choose the preferred solution of optimization objectives according to the facts. Finally, the validity of this model and algorithm was verified by a case of assembly plant materials distribution problem.
