jsimIO
jsimIO is a platform-independent Python library, compatible with Python > 3.x, which can be used to generate JSIM simulation models of a manufacturing system and run the simulation from a Python environment using the Java Modelling Tools (JMT) simulation engine.
GitHub repository: https://github.com/frabera/jsimIO

Features

jsimIO is able to generate simulation models for manufacturing systems with the following characterstics:
  • Multiple part-types
  • Open and closed part-type classes
  • Assembly operations (sub-assembly part types can be joined to a assembled part type)
  • Multiple drop and scheduling strategies
  • Multiple statistical distribution for modelling service times and arrival times.
For a detailed description, refer to the jsimIO Manual in the dedicated GitHub repository.
The available nodes to model the system are:
  • Source
  • Sink
  • Station composed by:
    • Queue of finite or infinite size
    • Server with single or finite number of concurrent jobs
  • Infinite Server (Delay)
  • Fork
  • Join
  • Logger

Measures

Many different measures can be selected as simulations result, such as the throughput or the average number of customers, both referred to a single node or to the whole system. For further information please refer to the JMT manual.

Simulation Log

Using the Logger station, it is possible to save a log of each event relate to part flowing by the station.
jsimIO can automatically add a preceding Logger station to each node of the system. In this way, at the end of the simulation a log file is saved as a .csv file containing all the events and part flows in the system for further analysis.
