Initial Release

Introducing the NASA Prognostics Models Package. The NASA Prognostic Model Package is a python modeling framework focused on defining and building models for prognostics (computation of remaining useful life) of engineering systems, and provides a set of prognostics models for select components developed within this framework, suitable for use in prognostics applications for these components.

Features of the initial release include:

• Parent class for models (prog_models.PrognosticsModel) - either discrete or continuous
• Tool for generating new models
• Tools for simulating model to time or threshold
• Tools for visualizing results (prog_models.visualize)
• Example models: Battery - Equivalent Circuit Model (BatteryCircuit), Battery - ElectroChem Model (BatteryElectrochem), Centrifugal Pump Model, Pneumatic Valve Model
• User Documentation
• Examples of package use, including:
  • Simulating a model
  • Simulating with complex future loading profiles
  • Simulating with different noise profiles
  • Creating a new model (through model_gen function or subclass)
  • Visualizing results
  • Benchmarking models
  • Sensitivity analyses
• User tutorial
• New model template
