Packing problems with performance constraints are categorized as combinatorial optimization problems with strong application background. This paper is concerned with the research on global optimization algorithms based solution for packing problems. Genetic algorithm as a kind of intelligent algorithm, can be used to solve problems of the global optimal solution but their efficiency is not quite satisfied due to their intrinsic NP-hard computational complexities. The paper improves the initial solu-tion of GA, and a multi-object optimization model is formulated on simplified satellite cabin packing problem. By comparison on a case of such packing problem constructed with traditional genetic algorithm which produces with random data, this algorithm is superior to the traditional GA and multiplier algorithm in the term of solution efficiency.
