The Study Of The Theory And Methodology Of Plant Management In Modern Large-scaled Enterprises Based On The Information Technology

To adapt to the new requirements of plant management in large-scaledenterprises in the knowledge economy and information society, the research on thetheory and methodology of plant management based on the information technologyin modern large-scaled enterprises is conducted in this dissertation. Based on themodern theory and methodology of plant management, as well as the moderndistributed information technology and artificial intelligence technology, the plantmanagement information platform is constructed. Then the theory, methodology andtechnology of equipment monitoring and running management system, thecooperative maintenance and production insurance system, spare parts managementmodes and intelligent equipment diagnosis system are explored from the perspectiveof the mid-term plant management. The main research work is divided into thefollowing parts:The part of plant management information platform model analyzes thecharacteristics and requirements of the platform in large-scaled enterprises, designsthe platform architecture adopting ESB (enterprise service bus) based on thedevelopment of modern distributed information technology, designs the standardplant management modules, and discusses the database management, runningenvironment and the information security.The part of equipment monitoring and running management system researcheson the integration of the offline monitoring wireless transfer trend analysis system,online intelligent monitoring and diagnosis system, equipment life cycle costanalysis and evaluation system based on the PMIS (Plant Management InformationSystem) information platform according to the theory of prediction maintenance, lifecycle cost control and decision, and also reliability. The topologies, key technologiesand models of the above systems are explored to realize the integrated equipmentmonitoring and running management system which is exploited to effectivelydiagnose the status of the control points of key equipments and control the technical and economical status of the equipments.The part of cooperative maintenance and production insurance system analyzesthe problems existed in traditional maintenance systems, such as dispersed andunbalanced maintenance capacity, high maintenance cost, and low production ratio,and then proposes a kind of new cooperative maintenance and production insurancesystem to solve them. Two typical modes are given. One of them isprofession-matrix and the other is profession-integration. The evaluation indexsystem is constructed and the evaluation method based on discrete mathematicsmodel is explored.The part of spare parts management modes analyzes the problems existed intraditional management methods and proposes three kinds of new managementmodes. The first is e-business based online supermarket model for low-value andlow-batch parts. The second is united storage sharing model for parts which willcause a great loss in case of breakdown though the probability of breakdown is low.The third is JIT (Just In Time) mode for general low-value-added consumable parts.The theory and methodology of the above three modes are explored.The part of intelligent equipment breakdown diagnosis system analyzes themodern theory and methodology of intelligent diagnosis. After that the keytechnologies of diagnosis platform model, logic reasoning model, data repository,management modules and remote data communication are studied. An exampleusing the above technologies is given.The part of research on practical cases applies the above theory, methodologyand technology of information platform, equipment running management, equipmentmaintenance management, spare parts management and breakdown diagnosis in thepractical plant management activities of Wuhan Iron and Steel Corporation Ltd andevaluates the economic benefits of the application.
