In complex engineering systems, collaboration between different design disciplines and optimization of whole system concurrently are caused an important issue in optimization. In recent decades the multi-disciplinary design optimization approaches and meta-heuristic algorithms have been used in this field. In this regard, a hybrid modified collaborative optimization framework and teaching-learning -based-optimization algorithm, for solving these kind of problems is presented here. We show efficiency of the introduced algorithm by solving test cases and comparison to former results
