Math. Artif. Intell. 37, No.4, 381-407 (2003).} \itemab Summary: In this paper we describe a formalism for integrating the SHOP HTN planning system with the IMPACT multi-agent environment. We define the A-SHOP algorithm, an agentized adaptation of the SHOP planning algorithm that takes advantage of IMPACT's capabilities for interacting with external agents, performing mixed symbolic/numeric computations, and making queries to distributed, heterogeneous information sources (such as arbitrary legacy and/or specialized data structures or external databases). We show that A-SHOP is both sound and complete if certain conditions are met. \itemrv{~} \itemcc{I.2.8} \itemut{multi-agent systems; HTN planning; heterogeneous/distributed data} \itemli{doi:10.1023/A:1021560510377} \end
