摘要: Planning for real world problems with explicit temporal constraints is a challenging problem. Among several approaches, the use of flexible timelines in and Scheduling (PaS) has demonstrated to be successful number concrete applications, such as, instance, autonomous space systems. A timeline describes an envelope possible solutions which can exploited by executive system robust on-line execution. remarkable research effort been dedicated design, build deploy software environments, like EUROPA, ASPEN, APSI-TRF, synthesis timeline-based PaS applications. Several attempts have also made characterize concept timelines. Nevertheless, formal characterization plans still missing. This paper presents account aiming at providing general semantics related planning concepts as domains, goals, problems, plans. Some basic properties defined are stated proved. simple running example inspired domain illustrate proposed notions. Finally, tool, called Extensible Library (EPSL), briefly presented, able generate that compliant given semantics.
