A flexible temporal planner

چکیده
The idea of including a flexible management of time in a temporal planner is the aim of this work. We propose an extension of a previous work of the authors [4] based on the use of fuzzy temporal intervals by defining a possibility measure over the continuous time line. This gives the planner some very interesting features like obtaining valid plans when the knowledge is ill defined, obtaining approximate plans when exact plans are not possible and provide a flexible time line of execution.

A temporal constraint network based temporal planner
This paper describes a preliminary work on Machine , a temporal partial order planner based on the use of temporal constraint networks to represent and propagate temporal constraints over the actions of a plan. The use of this formalism provide several advantages like the possibility of including deadline goals, makespans and imprecise temporal references able to obtain a flexible timeline for ...
متن کاملSome Issues about the Representation and Exploitation of Imprecise Temporal Knowledge for an AI Planner
This paper discusses the need for an AI temporal planner to represent ill defined and imprecise temporal knowledge for real world problems. The ability to deal with imprecise knowledge provides a flexible framework for temporal planning, in contrast with the rigidity of classical temporal planners, and it concerns all of the stages of the planning process, that is, from domain and plan represen...
متن کاملPlanning Under Temporal Uncertainty Using Hindsight Optimization
A robot task planner must be able to tolerate uncertainty in the durations of commanded actions and uncertainty in the time of occurrence of exogenous events. Sophisticated temporal reasoning techniques have been proposed to deal with such issues, although few existing planners support them. In this paper, we demonstrate the capabilities of a much simpler technique, hindsight optimization, in w...
متن کاملEnabling Fast Flexible Planning through Incremental Temporal Reasoning with Conflict Extraction
In order for an autonomous agent to successfully complete its mission, the agent must be able to quickly replan on the fly, as unforeseen events arise in the environment. This is enabled through the use of temporally flexible plans, which allow the agent to adapt to execution uncertainties, by not over committing to timing constraints, and through continuous planners, which are able to replan a...
متن کاملIntegration of fuzzy scheduling into a planning framework
This paper presents an approach for the representation and handling of soft temporal constraints in a planning framework. It is achieved in two steps. The first one is the representation of soft temporal constraints by means of fuzzy subsets of a real timeline. And the second one is the successful integration of the temporal reasoning capabilities of a scheduler able to handle these constraints...
