库存管理作为企业运营的关键环节，优化库存管理，不仅可以减少资源浪费，还可以加快物资与资金周转速率，利用计算机技术对库存管理信息进行科学化、智能化分析对企业的长远发展具有重大意义。

作为支撑国民经济发展的重要的能源基础产业，煤炭行业为我国经济腾飞做出了不可磨灭的贡献，但是由于长期以来粗放型的发展模式，也产生了资源浪费、环境污染等一系列问题。为了实现经济可持续发展，煤炭行业需要积极响应资源节约政策号召，构建纵横交错的协同采购体系，优化现有行业物资采购模式，改进现有煤炭供应物流体系，解决目前采购体系效果差、不稳定、不集中等问题，优化煤炭行业生产结构，同时也为构建资源节约型、环境友好型社会做出有益贡献。

随着现代化管理理念的兴起，ERP系统作为重要的资源管理工具被引入企业，ERP系统可以帮助企业更好地管理调配企业资源，调节企业供给与需求之间的关系。鉴于库存管理在供应链体系中的关键位置，本文以库存管理相关理论为指导，结合供应链管理思想分析如何进一步提升ERP系统在企业资源管理中所发挥的作用，从ZMHJ公司的技术分析和业务流程等角度分析如何优化ERP系统库存管理工作。在系统阐述库存管理、库存内部控制体系及ERP管理模型的基础上，分析ZMHJ公司库存管理基本情况和应用以来取得的效果，运用专家访谈法对参与相关工作的人员进行数据调研，获取信息进行分析，初步得到ZMHJ公司库存管理存在的主要问题，并从控制工作开展情况及系统自身分析出现问题的深层次原因；然后，基于ZMHJ公司的发展状况，从存管理模块与流程优化、安全库存设置优化以及需求预测优化库三个方面优化ZMHJ公司ERP系统库存管理模块；最后，论文归纳总结了在ERP环境下优化ZMHJ公司库存管理的保障措施。

本研究将有助于ZMHJ公司实现对库存资源的科学管理，盘活库存资源，减少损失和浪费，降低企业采购成本；库存管理的优化，有助于加快物资周转速率，减少资金占用，提升盈利空间；也有助于加强企业各个单元之间的工作连接，促使沟通更加高效顺畅，推动企业持续不断发展，增强企业的竞争实力。  

Inventory management is a key part of enterprise operations. Optimizing inventory management, it can not only reduce waste of resources, but also speed up the turnover rate of materials and funds. The use of computer technology to conduct scientific and intelligent analysis of inventory management information has great influence on the long-term development of the enterprise.

As an important energy-based industry supporting the development of the national economy, the coal industry has made an indelible contribution to my country's economic take-off. However, due to the long-term extensive development model, a series of problems such as resource waste and environmental pollution have also been generated. In order to achieve sustainable economic development, the coal industry needs to actively respond to the call for resource conservation policies, build a crisscross coordinated procurement system, optimize the existing industry material procurement model, improve the existing coal supply logistics system, and solve the current poor and unstable procurement system Optimizing the production structure of the coal industry, while also making beneficial contributions to building a resource-saving and environment-friendly society.

With the rise of modern management concepts, ERP systems have been introduced into enterprises as an important resource management tool. ERP systems can help companies better manage and allocate corporate resources and regulate the relationship between corporate supply and demand. In view of the key position of inventory management in the supply chain system, this article is guided by inventory management related theories, combined with supply chain management ideas to analyze how to further improve the role of ERP system in enterprise resource management, from the technical analysis and business of ZMHJ Analyze how to optimize the inventory management of the ERP system from the perspective of process. On the basis of systematically expounding inventory management, inventory internal control system and ERP management model, analyze the basic situation of ZMHJ company inventory management and the results achieved since its application, and use the expert interview method to conduct data research on personnel involved in related work and obtain information for analysis , And initially obtained the main problems of ZMHJ company’s inventory management, and analyzed the in-depth causes of the problems from the control work development and the system itself; then, based on the development status of ZMHJ company, from the inventory management module and process optimization, and the optimization of safety stock settings And the demand forecast optimization library optimizes the inventory management module of ZMHJ's ERP system in three aspects; finally, the paper summarizes the guarantee measures for optimizing ZMHJ's inventory management in the ERP environment.

This research will help ZMHJ company realize the scientific management of inventory resources, activate inventory resources, reduce losses and waste, and reduce corporate procurement costs; the optimization of inventory management will help accelerate the rate of material turnover, reduce capital occupation, and increase profitability; It also helps to strengthen the work connection between the various units of the enterprise, promote more efficient and smooth communication, promote the continuous development of the enterprise, and enhance the competitiveness of the enterprise.
