Abstract  With the background of the satellite module layout, the orthogonal rectangle packing problem with static non-equilibrium constraints is studied. By drawing lessons from quasiphysical strategy and defining embedded computing formula between each two rectangles, and between the rectangle and the circular container, this problem is converted into an unconstrained optimization problem. By incorporating heuristic configuration update strategies, local search strategy based on the gradient method and the simulated annealing algorithm with global optimization, a heuristic simulated annealing algorithm for orthogonal rectangle packing problem with static non-equilibrium constraints is put forward.The heuristic configuration update strategies in this algorithm produce new configurations and jump out of trap. The gradient method is searched for lower-energy minima near newly generated configurations. In addition, in the process of layout optimization, a static non-equilibrium penalty term on the basis of the extrusive elastic energy is introduced. Subsequently, by adopting the translation of the center of mass, the static non-equilibrium constraints of the whole system can be satisfied. The experimental results show that the proposed algorithm is an effective algorithm for solving the orthogonal rectangle packing problem with static non-equilibrium constraints.
