传染病模型系统动力学VENSIM模拟
模型流图如下：
公式如下：
(01) CR感染率=
IPC每次接触的感染率*IP患病人口*NCF额定接触系数*SR未患病人口
Units: **undefined**
(02) FINAL TIME = 100
Units: Month
The final time for the simulation.
(03) INITIAL TIME = 0
Units: Month
The initial time for the simulation.
(04) IPC每次接触的感染率=
0.1
Units: **undefined**
(05) IP患病人口= INTEG (
CR感染率,
10)
Units: **undefined**
(06) NCF额定接触系数=
0.02
Units: **undefined**
(07) P总人口=
100
Units: **undefined**
(08) SAVEPER =
TIME STEP
Units: Month [0,?]
The frequency with which output is stored.
(09) SR未患病人口=
P总人口-IP患病人口
Units: **undefined**
(10) TIME STEP = 1
Units: Month [0,?]
The time step for the simulation.
仿真结果如下：
