Call for papers
Workshop on Planning and Scheduling for Web and Grid Services

to be held in conjunction with

The 14th International Conference on Automated Planning and Scheduling,
(ICAPS 2004), Whistler, British Columbia, June 3-7 2004

Recently there has been increasing interest in service composition on the 
web and also in creating and managing workflows of tasks on computational 
grids. These important areas are related: grid toolkits such as Globus have 
recently adopted web service models and extended them to provide 
fault-tolerant services with long-lived state. Their extensions are 
generating interest in the web service communities. Using these models, 
widely distributed services can be discovered and composed into workflows 
either manually or automatically, revolutionizing approaches to distributed 
services.

AI planning and scheduling techniques will play an essential role in 
managing workflows of web and grid services, including their composition, 
allocation of resources, execution and repair. However, many issues remain 
to be resolved. These include (1) forming clean characterizations of 
service composition and execution and workflow management, (2) identifying 
the most appropriate ways to formalize service discovery and composition as 
a planning and/or scheduling problem, (3) determining whether existing plan 
and domain languages are appropriate or whether new features or languages 
are needed, and (4) highlighting important challenges for planning and 
scheduling systems to be maximally effective in this area.

This 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. Topics of interest include:

     * expressive description languages for services and workflows
     * automatic and mixed-initiative composition of services
     * execution monitoring and workflow repair
     * interleaving information gathering and workflow management
     * plan verification and plan quality for services and workflows
     * distributed workflow management

Please send submissions by email in either PDF or postscript format to 
blythe@isi.edu.

Important dates:

     * Feb 17 2004: Initial submissions due
     * March 16 2004: Notification of acceptance
     * March 26 2004: Camera-ready copies due
