Development Of Planning Module In Enterprise Asset Management System

Primary problem that the intensive enterprises of the assets pay closeattention to is that the assets efficiency is highest and the cost is lowest. Inthese decades, with the constant progress of the apparatus maintenancemanagement idea, apparatus maintenance has already developed fromafterwards trouble maintenance to the preventative maintenance which putsemphasis on maintaining in advance, and then further developed intoenterprise assets management of lifespan. Meanwhile, different kinds ofadvanced management modes are moving to maturity constantly too, suchas the whole apparatus maintenance which gives play to staff activity, andregarding behavioral analysis as the core, setting up reliable managementmode of procedure system which comes from the function, the trouble, thedependability and the result, etc. The information technology revolutionstarting from 20th century intermediate stages has brought the technologyinnovation of the field of plant maintenance. Enterprise asset managementsystem becomes one of the indispensable management tools of intensiveenterprise of assets more and more.The enterprise asset management system gradually appears in the1980s and moves towards the mature one which is always to state face theinformation solution of intensive enterprise. its predecessor is themaintenance of equipment management system which computerizes(Computerized Maintenance Management System, is called CMMS).Theenterprise asset management system is a set of advanced managementinformation system, which takes the property as the core and the serviceflow as the principal chain, covering property life cycle each link. Throughthe EAM system implementation, we will be able greatly to improve themanagement way of the enterprise interior property, lengthen the life ofequipment, reduce the operation cost and provide the highly effectivecooperation, enhance security and efficiency which the worker will do,reduce the down time, the control maintenance cost, reduce the componentsstock and the expense, enhance the purchase efficiency, fully use theequipment, the facility, the manpower and other resources. It can reduce theartificial loss, enhance the working efficiency, provide reliable guarantee forleadershipmacro-scientific policy-making. Simplifying the internal flow forthe enterprise, enhancing the efficiency and the enhancement competitiveability will provide the powerful help, the information will be sharing bymaximum limit, it can have the ability to come the maximum limit jointoperation between the profession various departments.This text has mainly introduced the whole framework of "EnterpriseAsset Management system EAM", the whole characteristic of the system,the whole characteristic of the system, the demand analysis of the function.Emphatically introduced the demand analysis and the detailed design ofplan module which participated by the author."Enterprise Property Management system EAM" mainly is suitable forthe property crowded electricity generation enterprise's informationmanagement of high value asset's maintenance, track. It takes enhancing theproperty to be possible used, takes reducing the enterprise movementmaintenance cost as the goal, takes optimizing the enterprise to service theresources as the core, through the information method, it reasonablyarranges the service of plan and the resources and activity are connected,thus it enhances the enterprise's economic efficiency and enterprise's marketcompetition strength1. "Enterprise Asset Management system EAM" is a typical MVC threelayers of system structure based on B/S structure:The model level expressions application procedure servicelogic, it is the application procedure core, it has sealed theapplication procedure construction of data and business logicprocessing, it has manifested the application procedurecondition, and may provide data to the view according to thechanges of its condition. The author uses EJB to realize theModel level development;The view is the surface which the user sees and interacts with,the module's outward appearance which it realizes is theapplication procedure external performance, it can visit thedata in the model, when the model changes, it can obtain thenotice and automatically renew. The view mainly is the htmpage;In the development we use Velocity to returns thecustomer page;The controller is responsible to receive the request of the user,carry on the user's data to the corresponding service logicmodule processing, finally according to the result choicessuitable view to the customer;Controller level is the linkrelation of the View level and the Model level, in theperformance history author used Servlet to realize this kind ofcontrolling function.视图控制器 模型请求选择调用通知访问Chart 1 Relationship among Model,View and ControllerThe MVC three systems structure is the current popular softwaresystem structure, uses the thin customer -server the way, puts the servicelogic on the server, provides the unification to the customer. Using threesystems structure, it causes the service logic and the expression logicseparated, between them the loose coupling enhances the system to bepossible expansion, stability and maintainability.Taking Hibernate as the mapping tool of the object -relations.The application procedure has the relations with the databasethrough Hibernate in order to operation data, through reads takesin the disposition document and the kind of mapping documentcontent, Hibernate produces the SessionFactory example, foundsthe Session object, completes in the Session object method withthe aid of Persistent Object to database operation.ApplicationHibernateDataBaseHibetnate.cfg.xml MaXpmpilngPersistent ObjectChart 2 Hibernate's role in whole application program2. "Enterprise Asset Management system EAM" fully uses computertechnology as well as the property and success experience of themaintenance of equipment, provides stock management and thestatistical analysis, the resource management, the preventativemaintenance plan, the workorder management, the equipment flawanalysis, the material purchase controlling which can realize thebusiness automation management.This system gets the enterprise property and production work inclose integration, according to the work experience it realizesenterprise's intellectualized management. Software takesworkorder's submits, examination and approval, execution,shutting down as a master line, takes the equipment movementhistory and an account as the foundation, takes enhancing theservice efficiency, reducing the overall maintenance cost as thegoal;According to flaw processing, the preventive maintenance, theforecast service several kind of possibilities patterns, integratesservice, human resources, stock, purchase into a informationsystem, it will be reasonable arranging related person, wealth,commodity and real-time data gathering system integration, thustransforming the traditional passive overhaul into the positiveinitiative preventive maintenance. Through recording enterprise'smaintenance history activity, we can transform individualknowledge into the enterprise scope intelligence capital;Through integrating work flow disposition function, we mayconveniently carry on the system business management;3. "Enterprise Asset Management system EAM" plan module is developedby author, its main function:Managing standard work plan, safe plan, safety hazard, safetyprecaution, segregation of security mark, including above fivekind of plans' create, inquiry, deletion, revision;Maintenance different plan's connection as well as the visitingbetween different modules. Standard work plan is a main body,the content of standard work plan is long lasting workexperiences' summary, it provides the work template using forcreating workorder, through using standard work plan inworkorder, we may use successful experience to solve currentlyfaces;The safe plan is for the standard work plan, its function isguarantee standard work plan carrying on safely and smoothly,each safe plan is connected with certain safety hazard;The safety precaution and the segregation of security mark is thecorrelation information of the property ,and they are connectedwith safety hazard, segregation of security mark contains a groupof operation, when appears the danger, we can follow thesequence of operation to eliminate the danger;In the performance history of plan module, the author uses the UMLmodeling technology, according to the request of the developing methodtakes the system structure as the central, in the object-oriented analysisstage creates analysis model, makes use case diagram, sequence diagram,class diagram, etc.
