执行队列中实体的求和[Arena模拟]

Question

在我的ARENA模型中，我有22个QUEUE，我想SUM它们的值并显示在我的动画中。问题是我的expression长度超过了256个字符的限制，因此我卡住了。下面是我想要的表达式：

NQ(TRAFFIC LIGHT AT N1.Queue) + NQ(TRAFFIC LIGHT AT N2.Queue) + NQ(TRAFFIC LIGHT AT N3.Queue) + NQ(TRAFFIC LIGHT AT N4.Queue) + NQ(TRAFFIC LIGHT AT N5.Queue) + NQ(TRAFFIC LIGHT AT N6.Queue) + NQ(TRAFFIC LIGHT AT N7.Queue) + NQ(TRAFFIC LIGHT AT N8.Queue) + NQ(TRAFFIC LIGHT AT N9.Queue) + NQ(TRAFFIC LIGHT AT N10.Queue) + NQ(TRAFFIC LIGHT AT N11.Queue) + NQ(TRAFFIC LIGHT AT N12.Queue) + NQ(TRAFFIC LIGHT AT N13.Queue) + NQ(TRAFFIC LIGHT AT N14.Queue) + NQ(TRAFFIC LIGHT AT N15.Queue) + NQ(TRAFFIC LIGHT AT N16.Queue) + NQ(TRAFFIC LIGHT AT N17.Queue) + NQ(TRAFFIC LIGHT AT N18.Queue) + NQ(TRAFFIC LIGHT AT N19.Queue) + NQ(TRAFFIC LIGHT AT N20.Queue) + NQ(TRAFFIC LIGHT AT N21.Queue) + NQ(TRAFFIC LIGHT AT N22.Queue)

你知道我如何在我的模型中执行这个求和吗？

对于将来访问此页面的任何人来说，我发现的解决办法是使用上面提到的长查询的值来定义variables。Arena本身不接受长expression，但它接受长查询作为变量值。因此，我定义了该变量，并在模型中的每个ASSIGN模块中更新了该变量。
