Research On Integrated Information Systems For Customized Product Based On Plm

According to the civil situation, it is the trend for the manufacturing in China to rebuild and upgrade current pattern of manufacturing with modern information technology. Information exchanging and integration are the basis of informatization. Without integrating, all kinds of enterprise's information systems only are automation and information isolated island and data information can't be shared, whole business process can't be unifiedly managed. The vitals of information isolated land are dividing up business process which are close linkages originally.Analyzing the main problems of project management, production management and procurement management in China's small and medium enterprises especially for assemble-to-order, guiding by the Product Lifecycle Management (PLM) concept, reengineering, optimizing, and dredging its each sector process relations, researching a suitable integrated information systems for small and medium enterprises, improving the ability to respond to market demands timely and management efficiency, to strengthen the company's synthesis competitive ability.Taking Tangshan henglian electric and mechanic equipment Co.,Ltd and its electric equipment product as research object, based on deep investigation into enterprise status and existing problems, aiming at the problem which the decisions are lack of the scientific basis and the poor ability of quick bid in project management, through reengineering the business process of project management, with the method of modular product configuration and supporting quick bid's project cost estimation, effectively solved the problems existed in project management; by standardizing the production management, based on standard hour machining operation and product's cost control material management, provided reliable basis for the enterprise production plans and project cost estimation; to optimize the process of procurement management, removing unreasonable phenomenon in the current stage of procurement process, standardizing the purchasing clerk's work process, setting up compare-stock mathematical model, accurately controlling the number of material purchasing, minimizing amount of inventory, economizing finances's liquidity, establishing the supplier evaluation mechanism, providing the quantitative basis for purchasing clerk to scientific and reasonable choose the suppliers, ensuring the timely delivery and the reliability of quality; on database security and role-based user access design, effectively guarantee the integrated information systems security. Through implementing and applying the integrated information systems, it has achieved the good effect of application.
