**5. Conclusions**

In this paper, we have proposed an effective hard computing technique to solve large-sized GCF incidences to the global optimum within a short computation time. The distinctive contributions of this paper are summarized as follows:


A limitation of the paper should be addressed. Unlike Danilovic & Ilic's part assignment rule [50], the part assignment procedure proposed in this paper does not guarantee the optimal part assignment since it is heuristic. The solution quality due to the assignment of a part depends on the assignment of other parts. Therefore, establishing sufficient conditions for optimal part assignment in the GCF problem will be a very attractive future research issue.
