Analysis Techniques For Man-Machine Systems Design

NATO UNCLASSIFIEDAC/ 24 3 (Pane l 8 ' TR/ 7Volume 2an application to the design of a prototype radar using the standard sequence for operating the equipment (a widelycited example by Cornell (1968) was actually an hypothetical application). Link analysis was used to evaluatecompeting human-machine interface designs during the sele.ion of a maritime patrol aircrafL Recently the techniquewas used for the development of interface designs for a forwari air defence system. Link analysis has also been usedwidely in crew compartment design, for example for patrol aircraft, for army command posts, and for the developmcntof improved designs of destroyer bridges.Quality assurance considerationsThe analysis is dependent on the frequencies and weightings used to weight the different links. The weightings aresubjective.Relationship to system performancerequirementsOperator performance is implicit in the use of the "cost" function to determine the arrangement of systemcomponents, resulting in reduced operator times, and errors. The cost function chosen will determine the exactrelationship to system performance.Referencesand Bibliography1. Cornel, C.E. (1968). Minimizing human errors. SpaceIAeronatlics. March, p. 79 .2.
