Vensim学习之Random Normal函数的使用

Vensim学习之Random Normal函数的使用

本例题比较简单，主要测试Random Normal函数的使用，vensim界面如下：

​​​​

第一个例题：(1) FINAL TIME = 100Units: MonthThe final time for the simulation.(2) INITIAL TIME = 0Units: MonthThe initial time for the simulation.(3) randomNumber=RANDOM NORMAL(-100, 100 , 0 ,50 ,2)Units: **undefined**(4) SAVEPER = TIME STEP Units: Month [0,?]The frequency with which output is stored.(5) TIME STEP = 1Units: Month [0,?]The time step for the simulation.(1) FINAL TIME = 100Units: MonthThe final time for the simulation.(2) INITIAL TIME = 0Units: MonthThe initial time for the simulation.(3) randomNumber=RANDOM NORMAL(-100, 100 , 0 ,50 ,2)Units: **undefined**(4) SAVEPER = TIME STEP Units: Month [0,?]The frequency with which output is stored.(5) TIME STEP = 1Units: Month [0,?]The time step for the simulation.​​​​第2个例题：(1) FINAL TIME = 100Units: MonthThe final time for the simulation.(2) INITIAL TIME = 0Units: MonthThe initial time for the simulation.(3) randomNumber=RANDOM NORMAL(-100, 100 , 50 ,10 ,2)Units: **undefined**(4) SAVEPER = TIME STEP Units: Month [0,?]The frequency with which output is stored.(5) TIME STEP = 1Units: Month [0,?]The time step for the simulation.​​​​
