第5讲 用AnyLogic进行多智能体仿真.ppt

第5讲用AnyLogic进行MAS仿真,5.1先看一个例子5.2对此例子进行概览5.3具体的学习5.4主要的statechartcomponents5.5动画的表示,之前的之前要看的视频,观看视频：航天神五、神六发射时，飞行控制室实况录相。注意，哪些地方应用了仿真技术为什么要用？不用行不行？,5.1例子：熟读唐诗三百首，不会作诗也会呤,销售渠道的模拟：背景：ThisisanAgentBasedmodelofasalesprocessinabusinesswhereclientsaretobereviewedbythecompany:e.g.thiscouldbeinsurance,banking,leasing,etc.TheprocesshasseveralstagesthataremodeledbydifferentstatesinthestatechartofaCustomerobject:initialcontact,quote,creditreview.Thecustomermayleaveoneachstage,andthecompany,inturn,mayrejectthecustomer.Themodelhelpsyoutoexaminehowtheskilllevelandsizeofthesalesforceandthecreditreviewteamaffecttheefficiencyofthewholeprocess.,5.2Agent的形成,A初始状态和属性Prospect的最初位置：Getx和getY,状态图,Statechart:Agent的各种状态在这里用图形方式表达，状态图中，将各种状态变化时的行为或者属性更改在此处写出，这里（可能需要用到各种Anylogic里的编程对象）例如：潜在客户prospect的变化状态。,在mainmodel中进行调用,用get返回对模型中各种对象的引用在不同的状态图中对这些对象进行编程和调用,各种变量和参数（二者有何区别？）,Mainmodel中的参数与变量各个不同的状态图中的参变量统计状态与表示思考：哪些变量要放在statechart中哪些要放在Mainmodel中？,集成运行,展示：salesfunnel,5.3具体的学习,StatechartEntryPoint、FinalstateStatechartentrypointisusedtoindicatetheinitialstateofthestatechart.Thereshouldbeexactlyonestatechartentrypointdefinedforeachstatechart.Youmaydefineseveralindependentstatechartsforthesameactiveobject,eachonedescribingsomeparticularprocess.InthiscaseAnyLogicwilldistinguishhowmanydistinctstatechartstherearebyanalyzingthenumberofstatechartentrypoints.,Generalpropertiesofstatechartentrypoint,NameThenameofthestatechartentrypoint.Thenameisusedtoidentifyandaccesstheentrypointfromcode.ShownameIfselected,thenameofthestatechartentrypointisdisplayedonapresentationdiagram.IgnoreIfselected,thestatechartentrypointisexcludedfromthemodel.PublicDefines,whetherthestatechartentrypointisvisibleonapresentationdiagramoftheownerofthisactiveobjectclass.Sincestatechartelementscannotappearonownerclasspresentation,thischeckboxisalwaysdeselectedanddisabled.ShowatruntimeIfselected,thestatechartentrypointisvisibleonapresentationatruntime.ActionSequenceofJavastatementsexecutedwhenthestatechartentrypointforwardsthecontroltoaninitialstate.,state,Staterepresentsalocationofcontrolwithaparticularsetofreactionstoconditionsand/orevents.Astatecanbeeithersimpleor,ifitcontainsotherstates,composite.Controlalwaysresidesinoneofsimplestates,butthecurrentsetofreactionsisaunionofthoseofthecurrentsimplestateandofallcompositestatescontainingiti.e.,atransitionexitinganyofthesestatesmaybetaken.,Transition,denotesaswitchfromonestatetoanother.Atransitionindicatesthatifthespecifiedtriggereventoccursandthespecifiedguardconditionistrue,thestatechartswitchesfromonestatetoanotherandperformsthespecifiedaction.Whenthisoccurs,thetransitionistaken.,转移发生时，执行的事件选择,Atransitionmayfreelycrosssimplestateandcompositestateborders.Ifthesourceofatransitionlieseitheronorinsideastate,andthedestinationofthattransitionliesoutsideofthestate,thenthatstateisconsideredexitedbythetransition.Ifsuchatransitionistaken,theexitactionoftheexitedstateisexecuted.Ifthesourceofatransitionliesoutsideastate,andthedestinationofthattransitionlieseitheronorinsidethestate,thenthatstateisconsideredenteredbythetransition.Ifsuchatransitionistaken,theentryactionoftheenteredstateisexecuted.Incaseapartofatransitionliesinsideastate,butbothsourceanddestinationareoutsidethestate,thisstateisconsideredneitherenterednorexited,分支选择：branch,representsatransitionbranchingand/orconnectionpoint.Usingbranches,cancreateatransitionthathasmorethanonedestinationstate,aswellasseveraltransitionsthatmergetogethertoperformacommonaction.Whencontrolpassesabranch,
