Analysis Techniques For Man-Machine Systems Design

NATO UNCLASSIFIED3 AC/243(Panel 8)TR/7Volume 2sis could reflect behavioural relationships. i.e.. the material. energy, or informational flows between sub-systems orsystem functions. procedural and chronological sequences of system functions. or event driven transitions betweensvstem states. These options are shown in Table 1.1 and explained in detail in section 2. A ship propulsion systemulthas been selected for the examples given in section 2. To facilitate the identification of analyses a template which in-.s dicates the category of the described analvsis is used.'edtenIn section 3 examples of system and function hierarchies as well as chronological function representations (flow,a diagrams) are given for different system classes. Due to different viewpoints or purposes of applied analyses differencescan be noticed in the examples. The given representations may assist system designers and engineers in developingsystem concepts. The different system classes include aircraft, land vehicle systems. ship systems. and an anti-tankweapon system.MISSION CONDLUCT CONDCT CONDUCT CONDU(-T1de- ASW AA ASUW EWde-IVi-Vcl.tISSION PLAN CODI CT TERMINATESCENARIO MISSIONS OPERATIONS OPERATIONStnn .2110OP'ERATIONSA D A ICvelshu-;il isteSWaineSUBFUNCTIONS SELFECT L.omlop-GROSS TASKS A PRFPARi-incitics-e often~tsasksLOSQEC,asis.r AirUISE(TIA DTERtN|ients TASKS | FRING | lIENTO T|RCT FIRINGMAKESUBTASKSFINAL- REAINES COMANDS DECISION1.oREVIEW ERF EIY VERF EEMNn.
