“…Furthermore, there are different utility trade-offs for knowledge reuse between general but under-specified models (e.g. walkthroughs; Wharton et al, 1994) and richer yet domain-specific models (Timmer & Long, 1997). More general models can target a wider range of domains but at a penalty of delivering less knowledge, while the converse is true for more domain-specific models.…”

“…Following Dowell and Long (1989), the two are modelled as structures, supporting behaviours-in both cases physical and mental (abstract). A model of the rATM worksystem is shown in the upper panel of Figure 3, following Timmer and Long (1997) and Timmer (1999). rATM operator physical behaviours ("pull down" (current speed menu-see earlier)) are supported by physical structures ("hand").…”

“…At the end of each scenario, the computer-based model of the domain generated a record of all interventions with all aircraft, and an analvsis of all aircraft states as a consequence of the intervention -safety and expeditiousness values (Dowell, Salter & Zekrullahi, 1994). From video data of each interactive scenario, operatortechnologv behavioural models were constructed (Timmer & Long, 1997). From such models, planning behaviour could be selectively extracted for more specific analysis, in terms of outcomes (instantiating the taxonomy) and thereby assessing costs.…”

“…From detailed models of worksystem behaviours (Timmer & Long, 1997), the outcomes for unexecuted plans can be categorised within the taxonomy. At Line 3, a future change of TAW's altitude is specified, for w^hen TAW is safe with respect to another aircraft SAM.…”
