Analysis Techniques For Man-Machine Systems Design

ACP243(Panel-8)TRn 2.Volume 2INTRODUCTION: OVERVIEW OF HUMAN ENGINEERING ANALYSISTECHNIQUESThis Volume consists of two parts and three appcndices. In this. Part 1. thirty-one analysistechniques which have been used by human engineering specialists are reviewed to a standard format in Part2, examples are given of different functional analyses of systems. Part I is divided into six sections whichcorrespond to the classes of human engineering analysis techniques:(1) system missions(2) system functions(3) system operator and maintainer functions(4) system operator and maintainer tasks(5) workload and possible errors of the system personnel(6) requirements for displays, controls, workspace and inter-personnel communicationas discussed in Volume 1. Most of the techniques reviewed permit the designers and developers of equipment andsystems to define, structure and decompose relevant information: they are not algorithms which transform input data.Thus they require some learning or experience. Each stage of analysis produces information for subsequent analyses(Figure 0.1).task sequences,Submissn.8-- ....... frequencies .|wtimes ands a2-dedn6; inteface &s -:-: .: ......... .ga atysi.rerequremensn/seq nt A -......Ioperatoractions-E--3. function :: D& times dictated-Aaocationperthemission phase, - -1 Iteracdistance, threat 0 I for tions fo in t analyses:&corresponding , V f- : : -- :iegnNo\requirementsIenvironmental to mission ,data phases operator/ \\ dictated by-, decomposed maintainer r X operatorto lower level functions A performance jfunctions corresponding ask sequence< om sinfrequencies, ...... ..... .:phases tie n -p~frmance.x v ~performance |requirements g : :tsk & tasksqec A/times, probityocompletionwrlaand likely errorsFigure 0.11: Information flow in the sequence of human engineering analysesN ATO U.N-C-LA S.SIFIED-2 -
