This volume includes all papers selected for plenary and poster presentation at ICAPS 2007. This year, the distinction between plenary and poster papers was based, not on the quality of the paper, but on whether it was considered to be of broad, or more focused, interest. The 45 accepted papers were selected from a total of 136 submissions. All submissions were rigorously reviewed by an international program committee, managed by a senior program committee. The senior program committee consisted of the three cochairs and an additional member, John Bresina, whose role was to handle chairs' papers. The papers present the latest advances in the field of automated planning and scheduling, ranging in scope from theoretical analyses of planning and scheduling problems and processes, to new algorithms for planning and scheduling under various constraints and assumptions, to empirical evaluation of planning and scheduling techniques in practical applications. They reflect recent research trends in the field toward the use of search and constraint reasoning in planning and scheduling; probabilistic planning models and algorithms; integrated frameworks for planning, scheduling, and execution; learning in planning and scheduling; and mixed-initiative systems.
