4.7.2 Subsumption Architecture
e subsumption architecture is adopted for the constitution of reac-
tive agents (Brooks and Connell 1986). is architecture decomposes
an agent into vertical modules where each is responsible for one type
of very limited behavior (Ferber 1997). ese modules perform their
tasks in parallel. e interactions between modules are fixed. ey
run through a dominance relation defined in the design. However, if
two modules are in conflict, then only the information provided by
the dominant module is considered. However, if the dominant mod-
ule is not working and the lower module produces a result, t
