Abstract


For manufacturing companies , the equipment in the enterprise occupies an extremely important position , it is an important asset of the enterprise but it is also the basic guarantee of its production capacity . Equipment Management Information System on the device can be achieved within the life cycle management of enterprise equipment efficiently , so that it can play an important role , for the preservation and protection of corporate assets smooth production has important significance. However, device information management systems are complex systems , its business logic complexity , development more difficult , the paper enterprise device management information system for a detailed study to improve enterprise device management level. In this paper, the equipment management business processes and characteristics of the equipment of the enterprise information management needs adequate based on the analysis , build the system function tree diagrams and IDEF0 functional model for the planned system to a complete understanding ; use the form and ask the user to view the user 's approach to building ER model for database design constructed a blueprint ; in the ER model into a relational model of the process, discussed in detail : the entity into a table in the process , as well as the contact maximum particle size of the foreign key into the design process and the minimum size design process ; tells SQL-based database of the implementation process , including: tables, constraints, and the minimum size of the implementation technology. This paper also studied the Pareto analysis, implementation techniques , corrective maintenance to achieve standardized management techniques . A brief introduction of the system purchase requisitions , spare parts inventory inquiry , inspection data input and query interface .
