To be competitive, an industrial robot picking fruits must be able to perform this task in an amount of time which compares to that needed by humans. Because the location of a fruit changes due to the picking of others, the determination of their location has to be performed on-line and also the associated path planning for the robot. This poses two major problems in the development of fruit-pi...

This paper investigates three different technologies for solving a planning and scheduling problem of deploying multiple robots in a retirement home environment to assist elderly residents. The models proposed make use of standard techniques and solvers developed in AI planning and scheduling, with two primary motivations. First, to find a planning and scheduling solution that we can deploy in ...

Aiming at the production scheduling problem in the hull block production, this study investigates the maximum use of the assembly blocks working platform. By transforming the scheduling problem into two-dimensional bin packing problem, this study explores the effective block spatial layout under the condition of spatial constraints. In order to improve the drawbacks of the lowest horizontal lin...

The 3rd and 4th International Planning Competitions have enriched the set of benchmarks for classical propositional planning by a number of novel and interesting planning domains. Although they are commonly used for the purpose of evaluating planner performance, the planning domains themselves have not yet been studied in depth. In this contribution, we prove complexity results for the decision...
