Then , the paper analyzes the existing problem in management mode of maintenance inventory of equipment and the improvement of these problems by tpl . meanwhile , analysis and discussion about building the management mode , construction tactics and risk precautions on the basis of tpl are carried on . at last , the case about managing the maintenance inventory of equipment by tpl abroad is analyzed ; the proved is beneficial to reduce the cost of maintenance inventory , and improve the management level and service quality , and finish the maintenance task easily 论文在分析现状和总结装备维修库存管理发展历程的基础上，首先，对第三方物流的行业发展、市场环境及现实意义等方面进行了分析，得出第三方物流管理装备维修库存是可行的；其次，分析了装备维修库管理存在的问题，在此基础上分析了第三方物流对这些问题的改善；第三，基于第三方物流的装备维修库存管理模式的实现、流程的优化、策略构建以及风险防范等进行了分析和探讨；最后，结合国外第三方物流管理装备维修库存的实例，分析讨论了在处理类似问题所可能出现的问题及影响因素，这些对降低维修库存成本、提高整体管理水平和服务质量，更好地完成装备维修任务是非常有益的。
Only if these enterprises are all of one mind , they can get profit . to the large enterprise as daxian limited company which is one of b to b companies , it need n ' t face at final customs , so its goal of supply chain management is to pursue efficiency and benefit of whole system , to make total cost at the lowest level 本文认为，对于像大连大显股份有限公司这样的国有大中型企业来说，它属于b ot型的企业，并不直接面向最终用户，其供应链管理的目的就在于追求效率和整个系统的费用有效性：使系统总成本达到最小，这个成本包括从运输和配送成本到原材料、在制品和产成品的库存成本。
Firstly , principles , characteristics and functions in three development stages of erp are introduced ; secondly , the dissertation takes a certain product in feng yang radiator corporation for example and analyses how to make the plan of its relative materiel under the guidance of erp theory , and then puts forward the idea of uniting materiel planning , materiel purchase and materiel storage and dropping the purchase cost and storage cost considering the whole supply chain ; thirdly , system analysis and system design for the materiel management subsystem are carried out and the result is presented . finally , the dissertation introduces key techniques in the process of development from technician ' s viewpoint 文章首先阐述了制造业信息管理系统发展的历程? ?从物料需求计划mrp到制造资源计划mrp ，再到企业资源计划erp ? ?介绍了erp三个发展阶段的原理、特点及其功能模块组成；接着以企业某一型号的产品为例运用erp思想中的物料管理理论分析了其相关物料的计划制定过程，提出把物料计划、物料采购和库存三者统一起来，从整个供应链的角度考虑降低物料的采购成本和库存成本的观点；然后采用客户机服务器模式，按照erp系统整体开发思路对物料管理分系统的开发进行了详细的系统分析与系统设计，并给出了分析与设计的结果，同时也从系统开发人员的角度介绍了开发过程中的关键环节和关键技术。
3 . inventory model under uncertainty demand environment , two kinds of service level including unit service level and cycle service level and their relation were studied . the solution to safety factor aimed at minimizing the total cost of inventory was given , therefore , some useable heuristic relation was found by linear regression with simple variable and multi - variables , together with bp neural network methods 讨论了从库存参数变量出发，以库存成本最低为目标，求得安全库存的递推解法，并由此研究了安全库存因子与参数之间的简化关系，用单变量和多变量线性回归及bp网络方法，比较了三种模拟效果，找到可用的简化模型关系。
