BehaviorSpace的结果

Question

我正在模拟一个教室，以求出教室电器的总能耗。现在我想在BehaviorSpace中运行模拟，这样我就可以通过改变教室中的学生数量来获得能量消耗。

在BehaviorSpace: measure中，使用这些记者，我将能量计算放在电子表格中，但在电子表格中，所有内容都显示为零。为什么会发生这种情况？

我不能运行您提供的代码，但我怀疑问题出在您的go过程中。BehaviorSpace将go过程视为一个永久按钮，也就是说，它将一直运行，直到滴答次数超过Time limit，或者直到被其他用户提供的条件停止。此外，BS仅在go过程的每次迭代结束时运行Measure runs using these reporters下列出的报告程序。它假设每一次迭代都需要一个滴答。但是，您的go过程只运行一次。while循环被执行time次，但这都是在go的第一次(也是唯一一次)迭代中执行的，在第一次迭代之后，stop命令将停止模拟。我不确定您为什么要使用simulation-timer而不是ticks来节省时间，但让我建议一个go过程，它将完成我怀疑您想要的事情。

to go    
  move-students
  tick 
  if ticks > time [ stop ]
end

在这种情况下，go将继续运行，BS将在go的每次迭代结束时报告能量计算，直到迭代次数(滴答)超过time。如果将BS中的Time limit设置为time，则if语句将是多余的，但如果还在BS外部运行模型，则不会。(如果您从界面选项卡运行，则go按钮应该是一个“永久”按钮。)

在appliance-on过程的末尾还有一个冗余的stop。

我可能在你正在尝试做的事情中遗漏了一些重要的东西，但这可能会让你开始解决你的问题。
