The paper considers how to integrate metaknowledge (MK) in cognitive models, in order to improve problem solving capabilities (definition of MK, how to collect MK in operators' protocols, how to integrate MK into other knowledge representations). As a result of empirical studies, a three layer model of MK is proposed with two opposite poles, which are domain independent resource management rules which generate MK rules, and domain specific procedures in which results of MK are implemented, and not MK itself. An intermediary level expresses domain specific MK rules which permit the construction of domain specific procedures. This three layer model could explain the various definitions of MK proposed in the literature (psychological or AI definitions) by considering that each of these definitions concerns a different layer. From a computer stand-point, a joint research programme between JRC Ispra and CERMA started in mid 1990 in order (i) to compute a common core of MK (resource management rules) into the respective cognitive computer models (NPP operator and combat aircraft pilot) with a relative freedom of choice of the AI tools and (ii) to compare the results on the respective domain specific procedures and problem solving abilities.
