英文摘要：

A method was proposed for optimization operation sequence based on constraint matrix and ant colony algorithm for the global process optimization problem of complex components. The constraint matrix included two parts, object constraint matrix and cost constraint matrix, according to ours rules, we united the two matrixes to one matrix. With the constraint of this matrix, operation sequence was optimized by using an ant colony algorithm,thus a right optimized operations sequence was obtained quickly. The result shows that this method has good practical effectiveness.
