From cognitive models to multiple decision makers support systems

Cadier F., Coppin G., Lenca P.

We present in this paper a new approach for building distributed decision support systems. Multiple decision makers support systems are devoted to assist setting a consensus while taking into account all aspects related to the distributed nature of the processes. This approach is based on the integration of the individual cognitive models of the decision makers of the team and on the modeling of the dynamics of individual decisions when being interleaved. Our model allows to detect and prevent extremal group behaviors and to identify the right information transfers to be set among decision makers. This model has been tested in a realistic application framework concerning decision making in Maritime Surveillance where several operators have to converge towards a unique decision in limited time. We conclude with proposing the main elements of a design methodology for decision makers support systems based on the proposed approach.

Wykorzystanie modeli niezawodności operatora w kształtowaniu cyklu obsługowo-naprawczego maszyny

W pracy przedstawiono zagadnienia wykorzystania modeli oceny niezawodności operatora w zadaniu zmniejszenia liczby i zakresu nieplanowych zabiegów obsługowo-naprawczych. Szczególną uwagę zwrócono na wykorzystanie modeli kognitywnych. Równocześnie wskazano na konieczność jakościowo innego usytuowania operatora maszyny w systemach diagnozowania technicznego stanu maszyn.

The paper presents the issue of use of operator reliability assessment models in the task in volving reduction of the number and scope of unscheduled maintenance-and-repair activities. Particular attention is paid to use of cognitive models. At the same time, we pointed to the necessity of finding a different location, from qualitative point of view, for the machine's operator in diagnostic systems used for determining machines technical condition.
