In the building, it will be the main component of frame structure, and also can be used as the main component of wire rod, having the advantages of high bearing capacity, high stiffness, light weight, good plasticity and toughness, good impact resistance and fatigue performance, saving materials etc.
Under the action of loading, the stiffness of the cellular steel column is weaken, so we should consider about geometric nonlinearity and material nonlinearity of large deformation to predict the stress redistribution after the formation of plastic hinge accurately[2].

Introduction Typically, the goal of setting inventory control is to effectively coordinate the acquisition, manufacturing and releasing of materials to meet market needs [1].
Lot sizing is not used, so quantity can be ordered and delivered and any allocation rule for material rationing to the local stock points is allowed (as far as the allocation quantity are non- negative). 7.
