🥛 Coffee and State Transition Modeling

The paragraph begins with a casual conversation about coffee preferences, specifically the use of milk. It transitions into a tutorial on modeling the coffee-making process using the concept of state transitions in system dynamics. The speaker explains the importance of milk in the process and introduces the concept of 'state', which represents the condition of an object at a given time. The milk's state changes from 'cold' to 'hot' through the 'Heating' process. This is modeled in OPCloud, where the transformation is represented as 'Heating changes Milk from cold to hot'. The speaker also discusses the input-output link pairs that connect the milk's state to the heating process. The paragraph concludes with a practical application of these concepts in the real world, such as the coffee-making process and the journey of a passenger through an airport, highlighting various state transitions.

Keywords

💡Coffee Making

Coffee making refers to the process of brewing coffee, which involves combining coffee beans, water, and sometimes additional ingredients like milk. In the video, coffee making is used as a practical example to illustrate the concept of transformation and state change. The process of adding milk to the coffee represents a consumption transformation, where milk is used up to create a latte.

💡Milk

Milk is a liquid produced by mammals and often used in coffee making to create beverages like lattes. In the video, milk serves as an example of an object that undergoes a state transition from 'cold' to 'hot' through the heating process, which is a key concept in the modeling of systems.

💡Latte

A latte is a type of coffee drink made with espresso and steamed milk. The term is used in the video to demonstrate the creation transformation, where the addition of hot milk to coffee creates a new product, the latte.

💡State

In the context of the video, 'state' refers to the condition or status of an object at a particular point in time. The concept is central to understanding how objects change during processes. For example, milk starts in a 'cold' state and transitions to a 'hot' state through heating.

💡Transformation

Transformation in the video refers to the change that an object undergoes during a process. There are three types discussed: consumption, creation, and change or state transition. The video uses the coffee making process to explain how milk is consumed to create a latte, and how its state changes from cold to hot.

💡Heating Process

The heating process is the act of increasing the temperature of an object, such as milk, to change its state. In the video, heating is used to transition milk from a cold to a hot state, which is essential for making a latte.

💡OPCloud

OPCloud is mentioned as a tool or platform where the imaginary line representing the transformation process is drawn. It seems to be part of the system modeling process, where the user can input the transformation details, such as 'Heating changes Milk from cold to hot.'

💡OPL

OPL likely stands for 'Object-Process Language,' which is used to describe the changes and relationships in a system model. In the video, the sentence 'Heating changes Milk from cold to hot' is an example of how transformations are expressed in OPL.

💡Input-Output Link Pair

An input-output link pair is a concept used in system modeling to represent the flow from an initial state to a process and then to a final state. In the video, the milk's transition from cold to hot is illustrated by an input link to the heating process and an output link to the hot milk state.

💡Modeling

Modeling in the video refers to the process of creating a conceptual or visual representation of a system to understand and analyze its components and behavior. The coffee making system is modeled to demonstrate the various transformations and state changes involved.

💡System

A system, in this context, is a set of interconnected elements or components that work together to achieve a specific purpose. The video uses the coffee making process as a system where various transformations occur, such as milk heating and coffee brewing.

Transcripts

Hi, again!

Do you take your coffee with milk? Come, I'll make you one.

Ok, remember , we need the milk because it's consumed in the cofee making process.

That will be enough.

We're going to use the milk to make the Latte.

Put it back in the machine.

And we're ready to go, just press the button.

Meanwhile, let's continue modeling our Coffee Making system.

After we have learned about

Ok, I think that would be enough.

After we have learned about two types of transformation - consumption and creation -

we'll learn about the remaining third type: change, or state transition.

The milk was still cold.

Before pouring it to the coffee, we want it to change from cold to hot.

To model this, we introduce the concept of STATE:

A state is a situation or position the object is... at some point in time.

Our milk is currently at state cold,

We wish to change the state from cold to hot.

To model this, we are now adding to Milk these two states.

The Heating process, which we are adding now to our model,

will change the Milk object from its input state: "cold"

to the output state: "hot".

To model this, we drag an imaginary line from the input state cold to the transforming process - Heating

In the table that just popped up in OPCloud, we select the option in which the sentence will be:

"Heating changes Milk from cold to hot."

Exactly what we want to model!

Indeed, this sentence is what we get now in our OPL window:

"Heating changes Milk from cold to hot".

The Milk object is connected to the Heating process with an input-output link pair

- a pair of links comprised of an input link from the input state cold to the Heating process,

and an output link from this process to the output state "hot" of Milk.

Now we can add the hot milk into your coffee.

The little milk we have left will go to HopCat - our little smart cat.

The capsule, here, also underwent state change - from new to punctured

This was done by the Puncturing process inside the machine.

Looking back at our flight journey system, we see state transitions there too.

Let's follow your journey through the airport. Before Flight Ticket Purchasing ends,

Passenger (you) is in a state of being pre-ticketed.

Once this process ends, the Passenger's state changes to ticketed.

Following Boarding, Passenger state changes from ticketed to having a Boarding Card.

Actually going on the airplane, which is also called Boarding, is physical,

as it changes the state of Passenger from outside the airplane to boarded.

Landing changes the Passenger's state from airborne to landed.

At this time, you thought you would have your suitcase in the Carousel,

so the Suitcase would be at state found.

Not retrieving it means losing it, changing its state from found to lost.

Finding does the inverse, and changes the state of Suitcase from lost back to found.

Back to your coffee, it is now ready!

Not less importantly, you now have the initial tools required to conceptually model any system!

With this knowledge, you already know how to create an initial model of an electric car,

and how to present this model to the company you are interviewing for - StoreDot.

The company develops ultra-fast charging batteries.

While driving, the electric car consumes electricity.

Here is the OPM model of this:

Following charging, each Cell inside the car's Battery changes from depleted to charged.

This means that the charging process changes the state of the cell from depleted to charged.

More critically, your application process to StoreDot changes your state from candidate to employee.

The learning process you have gone through so far is changing the state of your knowledge,

and through the Learning process you are gradually becoming an OPM expert.

You can use this knowledge in every company, product, or system you are involved with.

Input-output link pair is a pair of links from an input state to a process,

and from that process to the output state.
