Graph products for configuration processing of space structures

In this paper four undirected graph products and four directed graph products are presented for the formation of structural models. The undirected products are extensively used in graph theory and combinatorial optimization, however, the directed products defined in this paper are more suitable for the formation of practical structural models. Here, the directed and undirected products are employed for the configuration processing of space structures. This application can easily be extended to the formation of finite element models.
