Timelinebased

Timelinebased refers to approaches and systems that organize events, actions, or states along a time axis to coordinate behavior and outcomes. In timelinebased modeling, a timeline consists of events or intervals, each associated with attributes such as action type, parameters, and constraints. Timelines can represent a single agent or multiple interacting agents, and they are linked through temporal constraints that specify start times, durations, sequencing, deadlines, and resource usage. A central mechanism, such as a scheduler or constraint solver, determines feasible assignments of times and actions that satisfy the constraints and respect dependencies.

In timelinebased planning, the evolution of the world is described over time with actions that have durations and preconditions that can change. The approach emphasizes explicit temporal reasoning and synchronization across timelines, enabling parallel actions and contingencies.

Applications include robotics and industrial automation, multimedia production and broadcasting, interactive storytelling and games, and complex project management.

Advantages include explicit handling of temporal relationships, support for parallelism and contingency planning, and modular representations for different actors. Limitations include computational complexity, data requirements for accurate timelines, and debugging difficulties when constraints are underconstrained or overconstrained.
