초록
Currently, the improvement of logistic management in developed countries is changing stably and rapidly, especially centered on automation based on advanced technology. In addition, logistics support procedures and activities need to be improved in a more sophisticated and agile way according to the paradigm shift in future warfare. However, due to the nature of the military, efficient management is limited due to the variety of products in small quantities and diversification of size. Although AS/RS operation algorithms for automated warehouses have been commercialized, the optimization of arrangement in warehouse depends on the operator’s capabilities. With this in mind, the study was conducted. This study constructs the problem of ‘where and how much storage rakcs should be placed in an automated warehouse’ by modeling the naval warehouse for repair parts and presents a solution. Data on the storage and release of repair parts/tools accumulated in the logistics system used by the Navy for three years were collected. After pre-processing the collected data, MBA analysis was used to derive association rules for each part, and the optimal arrangement was calculated by applying the association rules derived to the allocation problem minimizing travel distance and time. Through this, the travel distance was reduced by 20.8% in the semi-automated warehouse, and the effect of reducing the movement time by 11.8% and creating 8.3% of free space in the full-automated warehouse was confirmed.
Abstract
Currently, the improvement of logistic management in developed countries is changing stably and rapidly, especially centered on automation based on advanced technology. In addition, logistics support procedures and activities need to be improved in a more sophisticated and agile way according to the paradigm shift in future warfare. However, due to the nature of the military, efficient management is limited due to the variety of products in small quantities and diversification of size. Although AS/RS operation algorithms for automated warehouses have been commercialized, the optimization of arrangement in warehouse depends on the operator’s capabilities. With this in mind, the study was conducted. This study constructs the problem of ‘where and how much storage rakcs should be placed in an automated warehouse’ by modeling the naval warehouse for repair parts and presents a solution. Data on the storage and release of repair parts/tools accumulated in the logistics system used by the Navy for three years were collected. After pre-processing the collected data, MBA analysis was used to derive association rules for each part, and the optimal arrangement was calculated by applying the association rules derived to the allocation problem minimizing travel distance and time. Through this, the travel distance was reduced by 20.8% in the semi-automated warehouse, and the effect of reducing the movement time by 11.8% and creating 8.3% of free space in the full-automated warehouse was confirmed.
