The paper takes the operation center of D company as an example, studies the packing material inventory control. Grouping by ABC classification, the paper establishes the joint order of multi-item inventory control model to determine the optimal order cycle, achieving the purpose of reducing inventory levels and inventory cost. Keywords-packing materials; inventory; joint order; multi-item

The aim of this paper is to evaluate the effective properties of composite materials with periodic random packing of ellipsoids of different volume fractions and aspect ratios. Therefore, we employ computational homogenization. A very efficient MD-based method is applied to generate the periodic random packing of the ellipsoids. The method is applicable even for extremely high volume fractions ...
