This study seeks to solve the optimization problem of different engineering designs by using nonlinear mixed integer programming mode. In the past, this type of engineering design optimization problem has been widely studied and discussed. They are usually solved through mathematical programming method or heuristics. However, there are more constraints and more constraints that cannot be satisfied. In solving this type of problems, we used a penalty guided cooperative particle swarm optimization to avoid the disadvantage of decreased efficiency from the increase of search spatial dimension and to raise the efficiency. In resolving some engineering design problems, the results shows that the solutions found by cooperative particle swarm optimization are equal or better than the best-known solutions from past literature. Thus, the results of this study indicate that cooperative particle swarm optimization is another effective method to find solutions to optimization problems.
