Researchers at NASA's Johnson Space Center have developed a Monte Carlo simulation tool that assists the International Space Station (ISS) program with determining logistics support resources. The functional Availability Simulation Tool (fASTER) simulates a multitude of different operational scenarios and allows for the effects of complex program resource restrictions and constraints including, crew maintenance time, carrier upmass capability, and sparing postulate. fASTER uses orbital replacement unit (ORU) reliability data and operational constraints to compute an average expected availability over time at the ORU level and at the functional level. Based on the expected ORU failure rate distribution, the model uses a random number generator process to simulate failures over the life of the station. The tool runs on a desktop personal computer and uses an intuitive user interface that facilitates fast set-up of each model simulation.

Benefits

  • Precise: Produces consistently accurate predictions
  • Flexible: Suits ever-changing configuration and operational priorities
  • Quantified: Measures risks to logistics support requirements
  • Productive: Reduces potential data errors and training time due to descriptive input screens and data field automation

Applications

  • Organizations designing, planning, and supporting new space vehicles
