用AnyLogic进行多智能体仿真-文档资料

1、1,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state chart components 5.5 动画的表示,2,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,3,5.1 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：This is an Agent Based model of a sales process in a business where clients are to be reviewed by t

2、he company: e.g. this could be insurance, banking,leasing, etc. The process has several stages that are modeled by different states in the statechart of a Customer object: initial contact, quote, credit review. The customer may leave on each stage, and the company, in turn, may reject the customer.

3、The model helps you to examine how the skill level and size of the sales force and the credit review team affect the efficiency of the whole process,4,5.2 Agent的形成,A初始状态和属性 Prospect的最初位置： Getx和getY,5,状态图,State chart: 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

4、户prospect 的变化状态,6,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,7,各种变量和参数（二者有何区别,Main model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state chart中哪些要放在Main model中,8,集成运行,展示：sales funnel,9,5.3具体的学习,State chart Entry Point、Final state Statechart entry point is used to indicate the initial state

5、of the statechart.There should be exactly one statechart entry point defined for each statechart. You may define several independent statecharts for the same active object, each one describing some particular process. In this case AnyLogic will distinguish how manydistinct statecharts there are by a

6、nalyzing the number of statechart entry points,10,General properties of statechart entry point,Name The name of the statechart entry point.The name is used to identifyand access the entry point from code. Show name If selected, thename of the statechart entry point is displayed on a presentation dia

7、gram. Ignore If selected, thestatechart entry point is excluded from the model. Public Defines, whether thestatechart entry point is visible on a presentation diagram of the owner of this active object class.Since statechart elements cannot appear on owner class presentation, this checkbox is always

8、 deselected and disabled. Showat runtime If selected, thestatechart entry point is visible on a presentation at runtime. Action Sequence of Java statements executed when thestatechart entry point forwards the control to an initial state,11,state,State represents a location of control with a particul

9、ar set of reactions to conditions and/or events. A state can be either simple or, if it contains other states, composite. Control always resides in one of simple states, but the current set of reactions is a union of those of the current simple state and of all composite states containing it i.e., a

10、 transition exiting any of these states may be taken,12,Transition,denotes a switch from one state to another. A transition indicates that if the specified trigger event occurs and the specified guard condition is true, the statechart switches from one state to another and performs the specified act

11、ion. When this occurs, the transition is taken,13,转移发生时，执行的事件选择,A transition may freely cross simple state and composite state borders. If the source of a transition lies either on or inside a state, and the destination of that transition lies outside of the state, then that state is considered exit

12、ed by the transition. If such a transition is taken, the exit action of the exited state is executed. If the source of a transition lies outside a state, and the destination of that transition lies either on or inside the state, then that state is considered entered by the transition. If such a tran

13、sition is taken, the entry action of the entered state is executed. In case a part of a transition lies inside a state, but both source and destination are outside the state, this state is considered neither entered nor exited,14,分支选择：branch,represents a transition branching and/or connection point. Using branches , can create a transition that has more than one destination state, as well as several transitions that merge together to perform a common action. When control passes a branch,
