The Planning Model

(Related publications: [PUBLink] [PUBLink] [PUBLink] [PUBLink] [PUBLink])

The previous chapters have provided basic specification and solving techniques that can be used to handle the agents' planning. This chapter introduces a planning model that makes use of these techniques.

The model focuses on resources. A resource consists of a temporal projection of a specific property's state (also called state variable or fluent) and a set of internal constraints, such as possible values and possible state transitions. A resource is also subject to further constraints induced by the plan, such as preconditions and state changes. Numerical as well as symbolic properties are uniformly treated as resources. For example, a production unit's Task Assignment, a battery's Power and the state of a Door are all resources:
