Optimization of a Block Stacking Storage Model for a Single Product using (s, S) Inventory Policy

(s, S) 재고정책하에서 단일제품의 확률적 Block Stacking 저장모형의 최적화

Block stacking, which involves the storage of unit loads in stacks within storage rows, is typically used in traditional warehouses to achieve a high space utilization at a low investment cost. In this paper, assuming that the demand size from a customer is an i.i.d. random variable, we develop a probabilistic block stacking storage model and its algorithm for a singles product, which minimizes the time-overage floor space requirement under an (s, S) inventory policy and the violation of the FIFO lot rotation rule only in a single partially-occupied row.
