Container Example

pydes.Container(sim, capacity=inf)

Containers have the capability to acumulate and provide continuous amounts of what contains. It is particularly useful to model non discrete accumulators like Tanks.

Parameters:

Name Type Description Default
sim Simulator

The simulator instance.

 required
capacity int | float

The capacity of the container, default is 1.

 inf

Methods:

Name Description
get

decrease the level of the container by some amount.
put

increase the level of the container by some amount.

get(amount=1)

Get some amount from the container.

Parameters:

Name Type Description Default
amount int | float

The amount to get from the container, default is 1.

 1

put(amount=1)

Put some amount into the container.

Parameters:

Name Type Description Default
amount int | float

The amount to put into the container, default is 1.

 1

level()

Get the current level of the container.

capacity()

Get the capacity of the container.

p2 = Process2(sim, container)
sim.schedule(p1.main)
