The 16th International Conference on Automated Planning
The English Lake District, U.K., June 6-10, 2006
Planning has primarily considered plans in the context of how they could be generated from the domain theory and problem specification. While synthesizing plans is useful and important, it puts heavy demand on how the information is modeled and available in an application. Beyond synthesis, they may also be acquired from domain meta-models or experts, or learnt.
As planning is employed in new applications like grid, web services, e-services, workflows and business processes to facilitate service composition to manage tasks and resources, there is a growing realization that acquiring plans is just one part of the complex process of how a plan is used in any real world application. Users want to generate plans only when needed and they want to know how they are using their plans. Once available, they may be organized in large collections, where they can be grouped along different purposes and are made amenable to the search, inspection, evaluation, and modification by human experts or automated reasoning systems. Eventually, plans will outlast their utility and be replaced by newer, better ones. This has lead some researchers to propose a life-cycle view of plans to bring together the various techniques needed to use plans in an application.
In this workshop, we will look at issues related to how plans are used after they are obtained and how they play a role in subsequent planning. For our purpose, we will consider plans and workflows as synonymous to stress the fact that beyond the PDDL plan representation, planning should also consider the generalized workflows representation which is not always automatically generated. The workshop will look at issues of acquiring plans (e.g., eliciting plans, learning them), synthesizing plans when the domain is incomplete, modeling updates to plans (e.g., through instructions), analysis techniques to manage plans, metadata generation, storage of plans and how to retire them.
This workshop covers an important source of challenge identified in the ICAPS 2003, 2004 and AAAI 2005 workshops on planning and scheduling for web and grid services that how the problem of practical interest is formulated and how the result is used. While the genesis of the motivation is in the above identified areas, we believe that the discussions will be relevant to the wider community involved in applying planning.
The workshop will bring together researchers who are working on these topics to discuss these issues as well as real systems that are under development. Those wishing to attend are encouraged to submit either a long paper of up to 8 pages in AAAI format, or a short position paper of up to 3 pages, to sbiplav __ in.ibm.com (replace " __ " by @).
