Software agent has much flexibility and adaptation,it is suitable to open and dynamic network environment and it canilluminatehumansocialresponsibilities.Amulti-agent system is composed of many interacted computingunits which are called Agents.An agent is autonomous in some degreeat least.It can determine which action should be taken to achieve thegoal designed.Each agent can communicate with other agents.Whilethe communication is not simply a data exchange,it's like a kind ofsocial activity,just like what happens in our everyday life:cooperate,collaborate,andnegotiate.The technique of Multi-Agent has been developed fast in recentyears.The effective integration of distributed and heterogeneousapplication sub system can be implemented by using the technique ofMulti-Agent. In this way, information and function can be shared andAgents can coordinate each other. Coupling relationship amongAgents is loose. These Agents are independent of others and actautomatically. There existing protocols that every Agent complies to.Agents finish the task by coordination and cooperation. Thedevelopment of theory and technique of Multi-Agent provides a newwaytoconstructanopenandintegratedsystemforenterprise.Computer technology is the most important technologyproduction in modern society; it is important force for societyadvancement. How to apply computer technology in solving real problem in kinds of fields in contemporary society is the hotspot andkeypointofresearch.According to requirement that Oilfield development documentmaterial existing in a oilfield oil extraction mine should be processeddigitally and managed based on information, requirement analysis andintrasite investigation has been finished. Subsequently, OilfielddevelopmentdocumentmaterialmanagementplatformmodelbasedonAgent has been proposed. The present platform can be described informula as: platform equals to middleware and business component.By using the thought of technique of middleware and Agent, theconcept of platform in thesis can be defined as: platform equals tomiddleware based on Agent and Agent. Oilfield developmentdocument material management platform based on Agent has beendesigned on the basis of this thinking. According to requirement andthe feature of application that Oilfield development document materialexisting in a certain oilfield oil extraction mine should be processeddigitally and managed based on information, Agent-orientedMiddleware Model (AMOP) has been proposed. And application ofOilfield development document material is constructed on the basis ofthismodel.Byusingthemanagementplatform,informationofOilfielddevelopment document material distributedonheterogeneous databasecan be normalized, in addition, Oilfield development documentmaterial of this factory can be processed digitally as well, andapplication software Agent workingon the material can be maintainedand managed effectively and dynamically. Other application ofOilfield development document on the basis of the platform will beopenandhastheabilitytoextendfunctionofsystem.Oil-field development reference material digitization processingandthe information management the role which act in the modernizedoilfield enterprise is more and more important. Oil-fielddevelopmentreference material digitization processing and theinformationmanagement modernized degree directly affects an oilfield enterpriseworking efficiency. The oil-field developmentreference materialinformation is the public foundation information,realizes the oilfield information system subsystem coordinationoperation link. Itsspecial status proposed to oil-field developmentreference materialdigitized processing and the informationmanagement a stricterrequest, to this system flexibility, vigorous andhealthy,thesecurity,mighttheextension,aswell asthemaintainabilityalsosetahigherrequest.Among the system design process, passes through face theAgentsoftwareengineeringthought. The AOMP model design unifies the Agent technology and themiddlewaretechnology, mutually cooperates by many Agent the formto realize themiddleware efficiency. This way causes system itself theway which byone kind open, the component and may entrust withheavy responsibilityto be able to realize. In the system distributedcomputing, the Agentautonomy and the transportability is easy torealize based on the AOMPsystem intelligence, and can fully use thenetwork resources; TheAgent cooperation and the stronger trafficcapacity causes many iseasy using the subsystem or the module torealize the division oflabor and cooperation, completes the morecomplex system functiontogether; The Agent concurrency enhancedthe system efficiency; TheAgent initiative and the emergency causesthesystemtheintelligentdegreeandfriendlinesscanstrengthen.Broke through to the curve to quantification sPT(scanning,Preprocessing, Tracing) the method.
