Construction, Oil Inventory Management System Based On Java Ee

Nowadays,there are enormous branches and frequent resource scheduling in most of large-size petroleum enterprises.But the current information system is insufficient to meet the operational requirements because of no comprehensive information sharing,unreasonable allocation of resources and lack of effective management of petroleum inventory.Therefore,it is necessary to establish a special management system in order to enforce the management of petroleum inventory.The inventory management system is proposed to meet the demand for petroleum inventory management.The system uses effective inventory control strategy and achieves share of the petroleum information.It reflects the petroleum storage overall and shares the information instantly by the reasonable operation rule and advanced technologic disposal.It also accomplishes reasonable inventory control by multi-sides' cooperation.Finally,it helps the company maximize the rational utilization of resources,reduce the cost,and meet the demand from customers.Firstly,the actuality and issues of the petroleum inventory management of large enterprises are discussed,and the necessity of inventory management system development is cleared about.On the basis of this,an analysis about management model and business processes is performed.Then the system architecture design is analyzed.The inventory management system is designed by using modular methods. The user management subsystem,demand plan subsystem,daily business subsystem and VMI(Vendor Managed Inventory) subsystem are analyzed in detail.The discussion is focused on how to implement flow management of the oil business based on Java EE.Thereby the integrity,consistency and accuracy of the commodity data are efficiently assured,and the business data is synchronized in all the aspects of management,also the reasonable inventory control is implemented.Finally,the integration and extensibility of the system are also analyzed.
