Technical Foundations
✔️ Describe the technical foundations of your component. Describe in detail the models, algorithms, or methods you use. If the documentation is available in a different source, for instance, an open access paper, provide here a high-level overview and links to external references.
Code blocks
You can enter block codes in Markdown cells surrounding the text you want to display as code using triple quotes (````) and adding the language name. For instance, the following code block will display some python code styled using Python language syntax:
# This is a comment
print("Hello, world!")
Tables
You can add a table like this in your document:
| This | is |
|------|------|
| a | table|
will display the following table:
| This | is |
|---|---|
| a | table |
The table cells are delimited by the (|) character. The first row and first column are used to determine the width of the table, so it is important to insert spaces if you want to control the table width and text alignment across the table. Also, note that the first row is used as headers, and that there is a separator between the header and the table body.
Note that the text in the table is automatically aligned to the left. You can control the alignment of the text using colons (:) after the column delimiter. For instance, the code:
```markdown
| Right aligned |centered aligned |
|----------------------------------:|:------------------------:|
| This is a right aligned column | and this one is centered |
```
see:
| Right aligned | centered aligned |
|---|---|
| This is a right aligned column | and this one is centered |
Lists
You can build itemized lists using the - character, and nested sublists using the tabulator or insert some spaces before the - character. For instance, the code:
- Item list number one
- Sublist number one
- This is a sublist item
- Sublist number two
- This is a sublist item
- And this is another
- Item list number two
- This is another sublist item
- Here, just one more sublist:
- One item
- And one more!
Creates the following list:
- Item list number one
- Sublist number one
- This is a sublist item
- Sublist number two
- This is a sublist item
- And this is another
- Sublist number one
- Item list number two
- This is another sublist item
- Here, just one more sublist:
- One item
- And one more!
You can also create numbered nested lists just using numbers before a '.' character. For instance:
1. Here we go
1. Sublist item 1
2. Sublist item 2
2. Here we go again
1. Sublist item 1
2. Sublist item 2
Will create this sublist: 1. Here we go 1. Sublist item 1 2. Sublist item 2 2. Here we go again 1. Sublist item 1 2. Sublist item 2
LaTeX equations
You can include mathematical expressions using LaTex notation wrapped using the dollar symbol as a delimiter. You can insert equations inline (in the same line) as text like:
This is an inline equation $e^{i\pi} + 1 = 0$
````
This is an inline equation $e^{i\pi} + 1 = 0$
You can also use the dollar symbol to include equations standalone in a new line. For instance, the code:
```markdown
$$e^x=\sum_{i=0}^\infty \frac{1}{i!}x^i$$
Will introduce an equation in a new line, like this:
$$e^x=\sum_{i=0}^\infty \frac{1}{i!}x^i$$
Latex cheat sheet
You can find a comprehensive cheat sheet for LaTeX equations here. You can also use Overleaf to find tutorials and edit equations online. However, we hope this table contains the most common LaTeX commands and symbols.
| Symbol | LaTex Command | Description | Example |
|---|---|---|---|
| $x^y$ | ^{x} |
Exponent. The expression in the exponent is passed between curly brackets ({}) | $x^{y+1}$ |
| $x_i$ | _{i} |
Subscript. The expression in the subscript is passed between curly brackets | $x_{i+1}$ |
| $\sum$ | \sum |
Summation. You can add subscripts and exponents to determine the range of the summation | $\sum_{i=0}^{10}{i!}$ |
| $\frac{x}{y}$ | \frac |
Fraction. Pass first the numerator and then the denominator using curly brackets | $\frac{1}{2}$ |
| $\int$ | \int |
Integration. Pass the expression to integrate and the variable to integrate over | $\int x^2 dx$ |
| $\sqrt{x}$ | \sqrt |
Square root. Pass the expression to square root using curly brackets | $\sqrt{x^2}$ |
| $\geq$ | \geq |
Greater than or equal to. | $\geq x^2 dx$ |
| $\leq$ | \leq |
Less than or equal to. | $\leq x^2 dx$ |
| $\neq$ | \neq |
Not equal to. | $\neq x^2 dx$ |
| $\alpha$ | \alpha |
Any greek symbol, using its english name (e.g. alpha). | $\alpha$ |
| $\beta$ | \beta |
Beta is another popular greek symbol. | $\beta$ |
| $\gamma$ | \gamma |
Gamma is another great greek symbol. | $\gamma$ |
| $\omega$ | \omega |
But Omega as in Omega level mutant is my favourite. | $\omega$ |
Matrices and vectors in LaTeX
You can just use brackets to insert vectors in LaTex, which is quite convenient. For instance, the code:
x = [1, 2, 3]
Defines a row vector x with the values 1, 2, 3.
Writing a matrix in LaTex is a bit more complicated. You can use the following syntax:
\begin{bmatrix}
1 & 2 & 3 \\
4 & 5 & 6 \\
7 & 8 & 9
\end{bmatrix}
To write a matrix like:
\begin{bmatrix} 1 & 2 & 3 \ 4 & 5 & 6 \ 7 & 8 & 9 \end{bmatrix}
Note that we write the matrix row-by-row, using two backslashes to separate rows, and the & symbol to separate cells in a row.
Integrated and Open Source Components
This section outlines both pre-existing technologies and open-source components that have been integrated into the HRC painting re/scheduler. It provides details on their sources, purposes, modifications, and compliance with licensing terms. In this solution we applied some existing technologies as FACOP and developed new products around them.
Overview
The HRC painting re/scheduler is a scheduling application that is integrated with the Collaboration Ambient Data Model database. It provides a seamless task management for painting production, and manage scheduling information easily. The application retrieves the required data from the database, which is used by the scheduler to provide a scheduling proposal for the required painting tasks. Once the schedule is approved, the application stores the scheduling for each task following the result and updates the information in the database. It also manages cobot training sessions when new products require painting programs.
Pre-existing Components
Collaboration Ambient Data Model
Source
The Collaboration Ambient Data Model is available in the AI-PRISM repository.
Description
The data model database serves as the central repository for storing and managing scheduling-related data. It includes records of human and cobot availability, tasks, training requirements and execution data. This structured data allows the scheduler to provide an optimized scheduling proposal for painting tasks.
Modifications
The data model has been adapted to include new fields and tables to support cobots in the scheduling of painting tasks.
Purpose in AI-PRISM
The data model database enables efficient and automated scheduling by providing structured access to processes and resources, ensuring an accurate scheduling based on the company resources and constraints. It also keeps track of cobot training sessions to ensure that the cobots are always up-to-date with the latest painting programs.

FACOP (Framework for Applied Computational Optimization Problems)
@megerar@iti.es I really dont know if this is necessary because the component includes all necessary to calculate the schedule, this should include also the user interface. And this description if too technichal from my point of view
FACOP is a set of libraries developed by ITI to accelerate the process of creating, testing, and deploying optimization algorithms. These libraries provide the necessary methods and components for constructing algorithms by combining existing elements. Each component is specialized in a specific process, such as data reading, solution generation, solution evaluation, solution comparison, objective measurement, among others. FACOP enables the creation of new components while reusing previously developed ones, allowing the construction of new algorithms by integrating different components capable of deriving solutions for a given optimization problem. In this solution FACOP was used to create and compose the scheduling algoritm used in AW pilot.
Modifications
Necessary components to calculate different scenarios schedules where developed, like several components needed to load external data, an three evaluation component to measure the proposed solutions values, two objective components. Some modifications where made to a genetic algorithm. We created and API that published some methods to send data and receive results in form of scheduling tasks. This API can compose the necessary algorithm for weekly and daily scheduling from a given configuration using FACOP components.
Purpose in AI-PRISM
FACOP is used in this project to create and execute algorithms for weekly and daily schedule, and also an algorithm for daily re-scheduling. All these schedules will incorportate the training of the cobot arm as part of the plant scheduling.

How to install
This component does not requiere further configuration to be used or installed.
How to use
The HRC painting re/scheduler is accessed through the browser interface. The user can log in with their credentials and access the scheduling application. The main functionalities of the application include both weekly and daily scheduling, which include both production tasks and cobot training sessions. To get the best scheduling proposal, the user needs to input the date, as this process is done weekly on mondays based on the information available by last Friday and new orders. The application will provide a scheduling proposal based on all orders that should be completed in the week, so the user can approve or reject, making the algorithm propose another schedule. Once one schedule is approved and stored in the database, the system will update all information, and the user can access the daily scheduling to check the tasks for the day. The information will be displayed through a visual representation of the tasks in a gantt component and also through a list of tasks with detailed information in a table.
Scheduling Tasks
The scheduling process is an automatic process, so when a new schedule is created the user only has to provide the date so the system get which week is being scheduled. Once it is introduced, all information required is retrieved from the database: available workers and cobots, task priorities, capabilities, and training requirements. After getting a scheduling proposal, the result will appear in the dashboard, where the user can approve or reject it. If rejected, the system will propose another schedule.
Scheduling Cobot Training
A training session is required if a cobot does not have a painting program for a new product.
