Mk. Alha et Vj. Pohjola, ELICITING EXPERT KNOWLEDGE - A STUDY ON CONNECTIONIST APPROACH FOR BUILDING A COGNITIVE MODEL OF PROCESS DESIGN, Computers & chemical engineering, 19, 1995, pp. 809-814
The conceptual stage of process design is the most crucial component o
f the overall design process because the decisions made at this phase
have a disproportionately large share of impact than later phases. A m
ethodology for the conceptual stage of the chemical process design has
been presented in Pohjola et al. 1994a, Pohjola et al. 1994b and Alha
and Pohjola 1994, This study aims at testing the design strategy sugg
ested in the methodology, the performance driven design strategy (Pohj
ola and Alha 1994). A combined method for eliciting expert knowledge f
rom verbal data was developed for constructing a descriptive cognitive
model of a design process. The method has its basis in connectionist
view of information processing and it utilizes parallel distributed co
mputing (neural networks).
