Modelling process#

When you want to buy something, you usually read the specifications of the item you want. For example, if you want to buy a new car, you might want to know how much it costs, how much horsepower it has, how much fuel it consumes, and so on.

With the same logic, the Simulator Automatic Warehouse library wants to know from the user How is your environment modelled?. In our case, the subject of modelling is an automatic warehouse.

A user should start here, from the modelling process of his industrial automatic warehouse.

The modelling can be digitised using a YAML file. In this file you can write the dimensions of your warehouse and the parameters of the simulation.

In the following code we can see a sample configuration where we use every available field allowed by the schema. The Json Schema used to validate your configuration can be found in the package you install from pip (in the automatic_warehouse-res folder), or online in the repository.

height_warehouse: 1000
default_height_space: 25
speed_per_sec: 1

tray:
  length: 390
  width: 180
  maximum_height: 140

columns:
  - description: "right_column"
    length: 400
    width: 250
    height: 325
    offset_formula_description: "width / 2"
    x_offset: 125
    height_last_position: 75

  - description: "left_column"
    length: 400
    width: 200
    height: 1000
    offset_formula_description: "(left_column.width / 2) + right_column.offset + 250"
    x_offset: 475
    height_last_position: 75

carousel:
  description: "carousel-bay_and_buffer"
  width: 250
  length: 400
  hole_height: 375
  bay_height: 150
  buffer_height: 150
  offset_formula_description: "width / 2"
  x_offset: 125

simulation:
  time: 10000
  num_actions: 100
  trays_to_gen: 5
  materials_to_gen: 3
  gen_bay: false
  gen_buffer: false

A full explanation of each field in the configuration can be found in the dedicated section (Configuration). Here we present a sample configuration that you can use to run your first code. Don’t worry if you don’t understand some of the fields, we have a special section where we talked about that. Also, this section should be a step-by-step guide to understand how to approach the library.

As you can see in the configuration, we have a warehouse with a height of 1000. The warehouse has two columns and a carousel. Each tray that you can find in the warehouse has some specifications. Finally, the simulation is set to perform 100 actions and create a warehouse filled with 5 trays and 3 materials.

Then we will save the configuration in a YAML file, e.g. my-config.yaml.
