Abstract

For all 8192 combinations of Allen's 13 relations between one task with origin o_i and fixed length ℓ _i and another task with origin o_j and fixed length ℓ _j, this paper shows how to systematically derive a formula F (o_j, o_j, ℓ_i, ℓ_j), where o_j and o_j respectively denote the earliest and the latest origin of task j, evaluating to a set of integers which are infeasible for o_i for the given combination. Such forbidden regions allow maintaining range-consistency for an Allen constraint.
