T公司航材库管和配送系统的优化研究

　　摘要：中国民用航空事业经历了几十年的高速发展，航空公司的机群己经扩大到相当大的规模，市场竞争也越发激烈。飞机维修是典型的知识、技术、资本密集型和高技术、高附加值、高风险、长周期的产业。为了提高航空公司的运营效率，很多航空公司已经把飞机维修外包给第三方维修公司。公司为了保障飞机维修的正常进行，普遍存在航材库存量偏高的现象。08年金融危机以后，很多航空公司都在对外包的飞机维修服务费用不断缩减，第三方维修公司为了保持利润，必须在运营成本上不断缩减。因此，保持合理的航材库存水平对保证航班正常运行和安全飞行起着非常重要的决定性作用。

　　精益思想目前广泛应用于供应链中的物流环节，在精益的物流模式中通过强调在物流的各个换件中减少浪费提高运输效率，降低钱、物、人流的运作成本来达到精益的物流管理目的，并最终为公司的运营部门提供利润贡献。基于对精益思想和精益物流理论的研宄和对国内外相关实践经验的了解，对T公司库存和配送的总体状况和目前存在的问题进行了总结和概括，针对总结出来的库存和配送各个环节存在的缺陷，本文运用Kraljic矩阵分类法将T公司航材分为四个矩阵，根据各个矩阵所属航材的特点提出T公司的供应物流进行精益改进方案，合理制定航材需求计划，日常库存管理改进，供应商管理改进；针对配送进行采用“拉式”配送系统，改良配送设施，提高配送种类的全方位覆盖，通过调整Milk Run Delivery配送使之与生产的节奏和需求相匹配来减少生产线边的停工待料，最后对优化方案实施的投入和节省的人力物力进行比较评价，得出了精益物流配送在T公司的执行中确实带来了显着的效果。

　　Abstract：With the continuous development of civil aviation industry China, the scaleof Airlines fleet increased sharply, the market competition is more and more fierce.

　　Aircraft repair is a typical knowledge, technology, capital intensive and hightechnology, high added value, high risk, long cycle of industry. In order to improvethe airline's operating efficiency, many airlines have outsourcing aircraft repair tothe third party repair company. The MRO service company in order to ensure theaircraft repair the normal, the air material inventory keep at high level. Afterthe 2008 financial crisis, many airlines curtailed at theexpense of aircraft repair service outsourcing,third party repair company in order tomaintain profits, must continue to shrink in operating costs. Therefore, air materialinventory level to ensure flight for the reasonable operation, and flight safety is veryimportant.

　　The lean logistics is a new logistics management mode currently andalso applied widely,it emphasizes the supply of high quality by eliminatingwaste, reduce non value added part of the logistics activities to achieve material, lowcost operation of logistics,and the shortest material delivery cycle. After reviewthe theory of lean logistics,the paper analyzed the general situation ofT companyinventory and distribution and the existing problems. Base on the aboveproblems, this paper classified subdivision material by using the KraljicMatrix,according to the characterizes of each kind of material property and leansupply logistics optimization scheme T company come out four schemes for eachkind of material . T company inventory management and distribution optimization.

　　According to the principle of Kraljic material classification firstly classified differentmaterials, reasonable development of material requirement planning, improvingthe inventory management,supplier management improvement; according to thedistribution of the “pull” distribution system, improved distribution facilities,improve the comprehensive coverage distribution types, increase Milk Run Deliverytimes to meet the production requirements, increase the distribution of advance theamount of the final evaluation, bring the optimization effect.

　　Key Words: Lean Logistics, Inventory Management, Distribution.
