Translating expert knowledge into production rules has been the most difficult and time- consuming when building expert systems (Buchanan at al. 1983). Especially. building hierarchical structure, i.e. developing sequential is dominant relationship among production rules is one of the most important and difficult processes. Hierarchical relationship among rule has been typically determined in the course of interviewing human experts. Since this interviewing procedure is rather subjective, however, the hierarchically structured rules produced in terms of interviewing is widely exposed to the severe discussion about their validity (Nisbett and Wilson 1977: Ericsson and Simon 1980: Kellog 1982). We thus need an objective method to effectively translate human expert knowledge in to structured rules. As such a method. this paper suggests the order analysis technique that has been studied in psychometrics (Cliff 1977: Reynolds 1981: Wise 1983). In this paper, we briefly introduce the order analysis and explain how it can be applied to building
