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：
