CT: In contrast to reactive agent architectures, deliberative architectures take up a different position
and emphasize a symbol-based reasoning process, which requires an agent to posses a local worldview. In line with the physical symbol system hypothesis (Newell and Simon 1976) symbol manipulation is necessary for producing general intelligent action. In consequence, it is often assumed that deliberative agents store their beliefs as logical formulae and have some inference mechanism at their disposal, which infers new knowledge and actions from the existing knowledge. Of course, this also means that deliberative agents are dependent on the efficiency and speed of the inference mechanism and possibly cannot react to urgent events as fast as needed. A well-known deliberative agent architecture is IRMA (Intelligent Resource-bounded Machine Architecture) (Bratman et al. 1988), which exploits traditional planning techniques for goal achievement. IRMA has been successfully used to explore agent reasoning in a relatively simple artificial environment called tile world, in which agents have to transport tiles to holes.
As both architecture styles exhibit weaknesses when implemented in their strict form, many hybrid architectures try to unify aspects from both approaches and therefore combine timely reactions with well-planned behavior. Hybrid architectures have gained high attention in practice and nearly all internal architectures, which are supported by agent frameworks, build on the balanced reactive as well as deliberative actions. Due to the high significance of hybrid architectures, in the following two typical representatives are presented in more detail.

N: 1. hybrid (n): c.1600, from Latin hybrida, variant of ibrida “mongrel,” specifically “offspring of a tame sow and a wild boar,” of unknown origin but probably from Greek and somehow related to hubris. A rare word before c.1850. The adjective is attested from 1716.
hybrid (adj): being offspring produced by parents of different races, breeds, species, or genera.
architecture (n): 1560s, from Middle French architecture, from Latin architectura, from architectus “architect” (see architect).
2. A methodology for detailed design hybrid architecture of intelligent service mobile robot (ISMR) is presented in this paper. Aiming at ISMR, the conceptual, logical, physical and hierarchical design model are discussed step by step in-depth from system analysis and agile manufacturing (AM) point of view. These analysis methods of down-up for designing ISMR provide new thought for building ISMR efficiently in engineering practice. Moreover, the detailed design processes based on this strategy are provided by a case study. The results have shown its effectiveness and feasibility.
