Table 1: Summary of selected iterated assignment architectures for MRTA. Shown here for each architecture are the computational and communication requirements, as well as solution quality.
"... In PAGE 12: ... Perhaps the most significant trend in these results is how similar the architectures look when examined in the manner. For example, the iterated ar- chitectures listed in Table1 , which assign all available tasks simultaneously, exhibit almost identical algorith- mic characteristics. Only the ALLIANCE architecture (Parker 1998) shows any difference; in this case the de- crease in communication overhead is achieved by hav- ing each robot internally model the fitness of the oth- ers, thereby effectively distributing the utility calcula- tions.... ..."

Table 1. Quality of Service (QoS) re- quirements in fleld communication
"... In PAGE 2: ... Deviation from an ideal simultaneity is referred to as jitter. The requirements in terms of com- munication quality in factory automation for the area near to the process can be roughly divided into three classes (see Table1 ). The deflnition of these rough classes is based on the experiences with existing classes of applications in the fleld bus technology.... ..."

Table 4 gives some examples for the determination of quality levels in different application areas. These quality levels are not based on technical criteria, but on different communicative goals which have to be achieved.

Table 9 provides an outline of recent studies that link task attributes to communication. Task has been a primary interest of group work in general (McGrath 1984) and of computer supported group work in particular (DeSanctis and Gallupe 1987; Zigurs and Buckland 1998). Most of the studies reviewed measure performance according to various combinations of task and communication medium, where performance includes quality of

Recent Studies of Task and Communication Quality Situational Attributes Use and Action-Oriented Impact Relationship- Oriented Impact Task analyzability Immediate feedback and multiple cues improve under- standing particularly for equivocal tasks (Dennis and Kinney 1998; Straus and McGrath 1994) but also asynchronous communication improves idea exchange in less equivocal tasks (Shirani et al.... In PAGE 42: ... Moreover, there is clear need for more empirical research on mes- sage form. Meanwhile, in the review of task attributes, there are no studies of task effects on relationship (see Table9 ). This is an area of potential research that is of particular significance to virtual organizations, which on the one hand will have to cope with decreasing levels of analyz- ability and, on the other hand, may depend on CMC to form relationships.... ..."
