....Each subclass is identified with a recurring pattern for evaluating a critique, implemented through EXPECT methods attached to the class. In addition to the ontology of critiques, the background theory uses an ontology of planning terms and a specialised ontology of resources based on Ozone [15]. More details about these can be found in [1] The critiques are defined operationally through EXPECT methods. For example, the method in Figure 2 says that a step satisfies an upper bound (a kind of critique) if and only if the actual value of the property to be measured by the critique is less ....

....difficult, at present, to see how easily Jini s resource model can be adapted to new environments. Related work in AI planning systems The closest resource modeling approach to ours is suggested in the DITOPS OZONE system. OZONE is a toolkit for configuring constraint based scheduling systems [13]. DITOPS is an advanced tool for generation, analysis and revision of crisis action schedules that was developed using the OZONE ontology. OZONE also incorporates a definition of a resource, contains an extensive predefined set of resource attributes, uses resource hierarchies, offers similar ....

Smith and Becker [31] offer a comprehensive analysis of the kinds of entities that need to be considered in such a mapping. 5.2 How are Agents Connected The configuration of an agent community describes the default communication paths among agents. While many systems provide a broadcast capability, a more ....

It is based on the work of (Kumara 1997) (Smith S.1996), and (Smith, D. 1996) The most significant specializations are an elaboration of Resource types. The first tier of specializations divides resources into a number of mathematically or logically disjoint types: ConsumableResource, ReusableResource, SynchonouslyReusableResource, ....

OZONE is a toolkit for configuring constraint based scheduling systems [12]. DITOPS is an advanced tool for generation, analysis and revision of crisis action schedules that was developed using the OZONE ontology. The closeness is evidenced by the fact that OZONE also incorporates a definition of a resource, contains an extensive predefined set of resource attributes, ....

....applications, the terms should be part of a common vocabulary understood by application domain experts, system developers, and final users. This language is defined based on a common terminology for planning and scheduling. This terminology defines an ontological model for planning and scheduling [Smith and Becker, 1997b] The opera tionalization of the concepts in this ontology through an implemented object oriented class library, and the mechanism to guide system configuration provide the modeling environment described in this thesis, the OZONE modeling framework. The tasks involved in implementing this ....

It defines entities, relations, and associates capabilities to concepts, but does not provide any functionality. Methods for developing ontologies have recently been proposed [Gruber, 1993, Uschold, 1996] A particularly ....

....control infra structure for configuring and arbitrating the use of different scheduling and analysis tools. Methodologically, our approach to analyzing the WFM domain is to consider the principal elements of the workflow scheduling problem in terms of the OZONE scheduling ontology (Smith Becker 1997). The OZONE ontology provides a conceptual framework for mapping the characteristics and constraints of a given application environment into the concepts and techniques provided by the class library, and hence a conceptual framework for constructing executable domain models (i.e. working ....
