Priority-based queueing in AnyLogic
问题
我是AnyLogic的新手，正在为一个真实的急诊科制作模型。我已经几乎完成了所需的一切，但是在优先级排队方面遇到了问题。在我们的模型中，患者有两种不同的优先级（红色和黄色），其中红色在排队时具有更高的优先级。例如，如果一个黄色优先级患者和一个红色优先级患者都在排队等待进行X光检查，应该先选择红色优先级患者（基于优先级的排队，而非后进先出）。
我看到了很多解释如何实现这一点的帖子，但是它们对我都没有起作用。我尝试在“患者”代理中创建一个名为“priority”的参数，并在SelectOutput的退出处使用“agent.priority=1;”来指定优先级，然后在Queue中选择“基于优先级”的选项，但似乎并没有起作用，我收到以下错误：
我还尝试将“patient.priority=2;”替换为“agent.priority=2;”，还尝试使用变量而不是参数，还尝试使用以下公式初始化变量的值：uniform() < 0.7 = 1 : 3。但都没有起作用。
有谁知道如何使用基于优先级的排队，或者我可以使用的某种解决方法吗？这是我成为工程师的最终项目！
我使用的版本是AnyLogic Professional 7.0.2
非常感谢您的时间！
英文:
I'm new in AnyLogic and I'm developing a model for a real Emergency Department. I have developed almost everything I need, however I'm having trouble with priority queueing. In our model we have 2 different priorities for patients (red and yellow), where red has a higher priority in queueing. For example, if a yellow-priority patient and a red-priority patient are both in queue for going to the X-ray, the red should be picked first (Priority-based queueing NOT LIFO).
I saw a lot of posts that explained how to do this but none of them worked for me. I tried making a parameter called "priority" within the "Patient" agent and using "agent.priority=1;" for assigning priorities on the exit of a SelectOutput and then selecting the "Priority-based" option in the Queue but that doesn't seem to work as I get the following error:
I also tried typing "patient.priority=2;" instead of "agent.priority=2;", also using a variable instead of a parameter, and also initializing the variable's value with the following formula: uniform() < 0.7 = 1 : 3. But this didn't worked.
Does anyone know how to use priority-based queueing or some sort of walkaround I could use? It's for my final project for becoming an engineer!
The version I'm using is AnyLogic Professional 7.0.2
Thank you very much for your time!

你正在使用一个非常旧的AnyLogic版本，该版本仍然使用旧的过程建模库，其中实体并不是真正的代理。你可以尝试使用entity代替agent。
在导致错误的字段（您输入了agent的地方），当光标位于字段中时，是否有一个小的“灯泡”？如果有的话，它允许您编写哪些关键字？请参阅这篇文章以了解我在谈论什么。
强烈建议您尽快升级 
英文:
You are using a very old AnyLogic version that still applies the old process-modelling library where entities are NOT actual agents. Instead of agent you could try entity.
In the fields causing the errors (where you typed agent), is there a small "lightbulb" when you have the cursor in the field? If so, what keywords does it allow you to write? Please see this article to understand what I am talking about
