Ergonomics/ Human Factors

1. Systems Engineering and Systems E/HF

   • System Ergonomics
     • Examines
       • A design system
         • People interactions with it
         • Doesn't concentrate on an individual
     • Accounts
     • Enhances
   • Systems
     • Singleton (1974)
       • Sytems have related objects changed over time and, for human-made systems, have a purpose
     • Chapanis (1996)
       • "Systems" is used in many ways, but equipment systems
         • Equipment systems
           • An interacting combination, at any level of complexity, of people, materials, tools, machines, software, facilities, and procedures designed to work together for some common purpose
     • Set of inter-ralated, coupled act. or entities (Hardware, software, buildings, spaces, communities and people)
       • Have a joint purpose, links between the entities which may be of state, form, function and causation
         • Changes and modifies its state and the interactions within it, given circumstances and events, and whichis conceptualised as existing within a boundary
   • Sytems engineering
   • Human System Integration
