Port Equipment Spare Parts Inventory Management Under The Environment Of JIT

An important part of the port facilities management is spare parts inventory management. The safe port spare parts requirements high, consumption of large, strong randomness, regularity is poor, difficult to forecast demand.JIT environment, production enterprise does not allow for pipeline shutdown, port enterprises face the same rush shipment, port machinery equipment allowed no downtime events. In such circumstance, how to carry out scientific and reasonable management of these port facilities and equipment, which can ensure the production operation smoothly, while the number of spare parts of equipment and facilities of the possession, liquidity ratio can reduce, has been plagued by the operator of port enterprises, but also the problem to be solved all port people.Combination of the automated warehouse management and VMI, JMI and other spare parts inventory management and port management theory, management method adapted to the port inventory research under the environment of JIT, introducing the present in the global high-end manufacturing enterprise application of VMI and JMI management model is extensive, learn from the successful experience of the equipment, spare parts inventory structure of port enterprises improved, thereby reducing the cost of holding inventory.Based on the spare parts of Tianjin port terminal companies in recent years, the use of facilities and equipment, spare parts and other comprehensive screening, analysis, summarized the characteristics of port equipment, spare parts management rules and existing problems, and according to the particularity of the port of spare parts, spare parts classification method into the rapid flow and slow flow. The case study, this paper according to the common problems of Tianjin port in spare parts management, analysis and improvement. For general spare parts, propose to partition the domain of stereoscopic warehouse management, distribution; for spare parts fast flowing, the spare parts consumption quickly in the port operations, inventory is very large, share enterprise liquidity ratio is very high, we propose to use the VMI model to management; and slow moving spare parts, these spare parts of single value is high, the inventory is not high, difficult to predict failure, once the fault loss caused by the larger, so the author uses JMI method to carry on the management.Through the model deduction analysis, spare parts classification method into the rapid flow and slow flow, to rationalize the management of spare parts, spare parts inventory can be effectively optimized structure, solve some shortage, capital rate is high. At the same time, the research results of this paper, is also a reference inventory optimization of manufacturing enterprise.
