SHOP and SHOP2 are based on a planning formalism called hierarchical task network planning. SHOP and SHOP2 use a search-control strategy called ordered task decomposition, which breaks tasks into subtasks and generates the plan{\textquoteright}s actions in the same order that the plan executor executes them. So, throughout the planning process, the planner can tell what the state of the world at each step of the plan.}, keywords = {automated planning, hierarchical task network planning, ordered task decomposition, planning (artificial intelligence), problem solving, search-control strategy, simple hierarchical ordered planner, trees (mathematics), uncertainty handling}, isbn = {1541-1672}, doi = {10.1109/MIS.2005.20}, author = {Nau, Dana S. and Au,T.-C. and Ilghami,O. and Kuter,U. and Wu,D. and Yaman,F. and Munoz-Avila,H. and Murdock,J.
