如何将概率分布与代理相关联-Anylogic [英] How to associate a probability distribution to Agents - Anylogic

问题描述

我正在Anylogic上模拟一个模型，在该模型中，代理从队列块流到服务块. 我需要用这样的概率分布来定义蚂蚁在服务中花费的时间:

I'm simulating a model on Anylogic, in which Agents flow from a Queue block to a Service block. I need to define the time spent by the angents in the service with a probability distribution like this:

-其中70％的人在服务中花费了15到30分钟的时间(应该是均匀分布，例如:Uniform(15，30))

-the 70% of them spent in the service a lapse of time between 15 and 30 minutes (it should be an uniform distribution like: uniform( 15, 30 ))

-其中20％在30至45分钟之间

-the 20% of them between 30 and 45 minutes

-其中45％至60分钟内的10％

-the 10% of them between 45 and 60 minutes

我已经将一个名为"timeInService"的参数与代理相关联，我想应该使用它，也许应该使用服务的Dalay时间，但是我不知道该怎么做.

I've already associated to the agents a parameter called "timeInService", I think I should work with it and maybe the Dalay time of the service but I dont'k know how.

非常感谢您！

推荐答案

在服务块延迟上，您可以输入以下代码:

on the delay of the service block you can put this code:

uniform()<0.7 ? uniform(15,30) : (uniform()<2/3 ? uniform(30,45) : uniform(45,60))

这将为您提供所需的内容.
另一种选择是在进入服务块之前先在该块上，然后在出口"上执行此操作:

This will give you what you want.
Another alternative is on the block before entering the service block you do this on the "on exit":

double rand=uniform();
if(rand<0.7)
    agent.timeInService=uniform(15,30);
else if(rand<0.9)
    agent.timeInService=uniform(30,45);
else
    agent.timeInService=uniform(45,60);

在服务延迟中，您将agent.timeInService

这是两个可能的选择.
