【Abstract】 A layout optimization problem is discussed, that is, to locate a group of cuboids and cylinders onto the up and down surface of a supporting board in a rotating module, which is a simplied satellite one. This problem belongs to 3-D packing layout optimization one with behaviour constraints and NP-hard one. The mathematical model, solving process and a heuristic algorithm are given. The idea of the algorithm is to construct non-homogeneous topo-model as much as possible and to search for near-optimal solution under each topo-medel. During the process of optimization, a stepped method is adopted which carries out 2-D layout at first and then the 3-D layout. Some examples are shown afterward.更多还原
