Abstract: One of the many complexities of multinational coalition operations
stems from differences in culture, military procedures, and command and control
processes between the cooperating command centers. These differences
can influence the interactions between decision makers of different command
centers and can affect the outcome of the coalition operation. A
coalition model, composed of individual models of the five-stage interacting
decision maker model, was used in a virtual experiment. The
subjective parameters included in the decision maker model can be any attribute
that characterizes the heterogeneity of the decision makers. In this
case, the parameters of power distance and uncertainty avoidance were used, two
of Hofstede's (1991) cultural dimensions. The accuracy and
timeliness of the coalition's response was used to evaluate its performance as
a function of heterogeneity. Including the presence of heterogeneity in the
coalition model, through the use of subjective parameters, is the first step in
formalizing the process for developing adaptive coalition architectures.
