LiSTOT General Discritpion

LiSTOT was created at the Institute of Astronautics as a trade off tool for environmental controll and life support systems (ECLSS). It combines the commonly used equivalent system mass (ESM) metric as described in "Advanced Life Support Equivalent System Mass Guidelines Document" with a multi criteria based approach (MCA) as described in "Multi-criteria Decision Making Methods". This enables LiSTOT to consider the usual ESM metrics (Mass, Volume, Power, Cooling, Crew Time) but also consider further relevant parameters like the Technology Readines Level (TRL), Maintenance and Reliability.

LiSTOT has the following features:

  • Excel VBA calculation tool with a documented Graphical User Interface which guides the user through the different steps necessary to perform an analysis
  • Built-in user guide to explain the tool and lead the user through the calculations
  • ECLSS technology database with all relvant parameters and the corresponding references for the parameters used in the tool
  • Variable and adjustable crew schedule
  • Combined MCA and ESM analysis
  • Built-in sensitivy analysis
  • Graphical interface for mass flows in the system
  • Preliminary dynamic analysis of e.g. power consumption, CO2, O2, relative humidity, etc. (For detailed anaylsis please refer to our dynamic ECLSS modelling tool V-HAB)
