Create a simulation

For starting a simulation, the following files must be created:

  • Main.py: starts simulation

  • production_config.ini: initializes the production

  • controller_config.ini: defines the controll strategie, e.g. routing, scheduling

  • logger_config.ini: defines how the KPIs and events should be saved

  • owl_config.ini: ontologysim path and save options

  • pnml-files: defines the product types

First simulation run

For a quick start the required files are already build and could be found in the /example folder.

Go to the /example/Main.py and run this python file.

This simulation exist of:

  • 1 machine

  • 1 transporter

  • 1 product type

Adapting the simulation run

Main.py

Explanation of the Main.py file

  1. Initialize the initialization and set the current dir correctly

current_dir = os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe())))
parent_dir = os.path.dirname(current_dir)
sys.path.insert(0, parent_dir)

init=Initilizer(current_dir)
init.initSimCore()

  1. define all needed config ini files

production_config_path="/example/config/production_config.ini"
owl_config_path="/example/config/owl_config.ini"
controller_config_path="/example/config/controller_config.ini"
logger_config_path="/example/config/logger_config_simple.ini"

  1. create production

    • either load from owl file or create vom production_config.ini

#choose between load from owl or create from config
init.createProduction(production_config_path,owl_config_path)
#init.loadProductionFromOWL("ontologysim/example/owl/production_without_task_defect.owl")

  1. add task

init.addTask(production_config_path)

  1. add defect (optional)

init.addDefect(production_config_path)

  1. add logger

init.addLogger(logger_config_path)

  1. load controller

init.loadController(controller_config_path)

  1. set a additional save time for the ontology (option)

init.set_save_time(400)

  1. run simulation

init.run()

Production config

Defines the production, e.g. number of machines, transporter .. For further infos view: production config

Controller config

Responsible for defining the used control strategies: For further infos view: controller config

Logger config

Responsible for logging the kpis, events and allows to set a live plot For further infos view: log config

PNML

Defines the product type, each product type has it’s own pnml-file For further infos view: pnml

OWL

Defines the java path and gives save options For further infos view: owl config
