This paper presents a library of problem-solving methods dedicated to production scheduling, and reports our experience in applying the library to the development of a real-life system. The library consists of three loosely coupled sub-systems: a manufacturing domain model, scheduling methods and graphical user interfaces. The domain model provides fundamental concepts to be employed by the other two sub-systems. In particular, the relationship between scheduling methods as articulated in terms of the structural relations among concepts in the domain model. Application systems developed with the library can be extended by modifying the configurations of the sub-systems and elaborating the concepts in each sub-system. The reusability of the library is investigated in terms of the ratio of code reuse in a real case. Finally, we compare our approach with related studies, and draw implications for designing domain-oriented libraries of problem-solving methods, taking account of the transition of knowledge-modelling perspectives.
