The author's chosen domain is the scheduling of aircraft maintenance work. Scheduling - which I take as defined as the selection and sequencing of resources over time to perform a collection of desired tasks - involves reasoning about resources. Reasoning about resources is a common phenomenon. It is a useful way of representing many domains, a natural way for humans to think about problems, and, consequently, an important aid to interaction with a planning system. Therefore, I am designing a resource-oriented planner. My central idea is to represent resources as objects, in the object-oriented programming sense. Possible worlds are super-objects containing all the objects and some object-classes. All the possible-worlds after a decision event are related to their parent, pre-event possible-world. Each resource will have behaviours for sending messages to other resources and for maintaining its own time-line and other attributes. Infeasible plans will be shown up as clashes on one or more resources' time-lines. In essence, the time-lines maintain temporal truth about the plan-world.
