Presentation Title
The Application of Living Systems Theory to Mars Missionsfor presentation to The Mars Society August 2013 Gary V StephensonLinQuest [email protected] 20130OutlineIntroduction to Millers Living Systems Theory CategoriesAn alternate way to decompose system requirements based on living systems functionsA way to use UML based functional decomposition to model biological functionsApplications of Living System Theory (LST) to Space ECLSSLST on ISS, LST in Transhabs and Surfacehabs, and LST in EMU & SMU SpacesuitsThe Application of Hatley-Pirbhai (HP) Diagrams to LST CategoriesA way to sort LST categories as input, processing, and output activitiesMass-Energy (ME) and Information Processing (IP) HP Templates are recommendedMission Directed Personnel, Information, and Mass-Energy FlowsPersonnel & Info flows in mission contextMass-Energy flows in local context ,for Transhab and for Surfacehab Conclusions and Next Steps
Prediction: LST modeling will become more meaningful as aerospace and biotech systems begin to merge1IconTrigraphCategory NameIconTrigraphCategory NameMATTER-ENERGY LST CATEGORIESINGIngestorSTRME StorageDSTDistributorEXTExtruderCNVConvertorMOTMotorPRDProducerSUPSupporterINFO-PROCESSING LST CATEGORIESINTInput TransducerMEMMemoryITLInternal TransducerASCAssociatorDCDDecoderDECDeciderTIMTimerECDEncoderNETNetworkOUTOutput TransducerBOTH M-E AND INFO LST CATEGORIESBNDBoundaryREPReproducer
