Triply Articulated Modelling in Complex Systems
International Conference on Complex Systems, Boston, (Mai 2004)
Zusammenfassung
We argue that traditional systems engineering (TSE) is inadequate
for engineering complex systems. This inadequacy becomes particularly
problematic when the system in question is a System of Systems (SoS)
whose behaviour depends on how human users of the component systems,
anticipating the consequences of their own behaviour, interact with
those systems and with each other. Considering its users to be part
of the SoS renders such a system anticipative, and therefore necessarily
complex. To be effective, the designer of an SoS must incorporate
an understanding of its users’ models of their contexts of use.
However, the process of design then becomes reflexive, since it
must include within itself models of its users’ anticipations
of its relation to the SoS’s environment, including those of its
designers. As a result, complex systems engineering (CSE) has to
become a distinct discipline, involving explicit processes that
occur at the time of use of an SoS, not only for negotiating shared
meaning between component systems within peer-to-peer relationships,
but also for considering the dynamic effects of differing uses of
component systems on the behaviour of the SoS as a whole. By modeling
users’ relations to demand as well as to the behaviour and organisation
of component systems, triply articulated modeling supports the negotiation
of shared meaning and accommodates the reflexivity required of a
CSE regimen.
