An alternative solution to optimal control problems using collaborative optimization (CO); an MDO method with decomposition strategy; is discussed. A collocation method is used for converting problem into a finite-dimensional nonlinear optimization problem. It is found that to avoid a high-dimensional system-level problem; CO tends to be most effective in weak-coupled problems; problems with few global variables; and the formulation of problem exactly satisfies this requirement. The results show that the objective value of CO is slightly smaller than that of the integrated solution; which is due to the allowed relaxed tolerance (10-5) of the system-level constraints. There are slight inconsistencies between the system-level target and the responses of the suboptimizations; which are also due to the relaxed tolerance in the system-level constraints;
