Abstract : Production systems are commonly used in cognitive modelling research. However, most production system implementations are difficult to program because of the syntax complexity of the rules, and the presence of obscure interactions between rules resulting from system features such as conflict resolution. PPS is a production system implementation in which simplicity of syntax and explicitness of control structure have been emphasized. Experience with several modelling projects suggests that this approach is well suited for cognitive modelling. This paper describes the production rule syntax, and summarizes the data structures and algorithms used in the implementation. Keywords: Cognitive models, Production systems, Rule based system.
