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 = 100
Units: Month
The final time for the simulation.
(2) INITIAL TIME = 0
Units: Month
The 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 = 1
Units: Month [0,?]
The time step for the simulation.
(1) FINAL TIME = 100
Units: Month
The final time for the simulation.
(2) INITIAL TIME = 0
Units: Month
The 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 = 1
Units: Month [0,?]
The time step for the simulation.
第2个例题:
(1) FINAL TIME = 100
Units: Month
The final time for the simulation.
(2) INITIAL TIME = 0
Units: Month
The 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 = 1
Units: Month [0,?]
The time step for the simulation.
本文通过两个示例介绍了如何在Vensim软件中使用RandomNormal函数生成正态分布的随机数。示例详细展示了设置模拟的时间范围、初始化时间、随机数参数等步骤。
