Modelling Task Knowledge Structures in Demos 2000

[摘要] Task Knowledge Structures provide an account of the knowledge structures that people possess and use when performing a task. Such models can be constructed using various techniques, such as direct observation, interviews, questionnaires, and others. TKS models can represent either knowledge structures that are possessed by a specific individual or, alternatively, a number of such individual TKS models can be amalgamated to form new TKSs. Demos 2000 is tool for specifying and executing mathematical simulation models of systems. The structure of Demos 2000 models can be considered to be based on the resources and processes that describe the system components and a stochastic representation of the (dynamic) environment within which the system resides. This report summarizes our work in translating models of human behavioural characteristics, as represented by Task Knowledge Structures, into Demos 2000 models.
