HIERARCHICAL MODELING APPROACH FOR PRODUCTION PLANNING [PDF]
IFAC Proceedings Volumes, 1992 Abstract Production management problems are complex owing to large dimensionality, wide variety of decisions of varying scope, focus and time-horizon, and disturbances. A hierarchical approach to these problems is a way to address this complexity, wherein the global problem is decomposed into a series of top-down sub-problems.

Hierarchical Planning With Annotated Skeleton Guidance
IEEE Robotics and Automation Letters, 2022 We present a hierarchical skeleton-guided motion planning algorithm to guide mobile robots. A good skeleton maps the connectivity of the subspace of c-space containing significant degrees of freedom and is able to guide the planner to find the desired solutions fast.

Hierarchical D ∗ algorithm with materialization of costs for robot path planning [PDF]
, 2005 In this paper a new hierarchical extension of the D ∗ algorithm for robot path planning is introduced. The hierarchical D ∗ algorithm uses a down-top strategy and a set of precalculated paths (materialization of path costs) in order to improve ...

Molecular Oncology, EarlyView.To integrate multiple transcriptomics data with severe batch effects for identifying MB subtypes, we developed a novel and accurate computational method named RaMBat, which leveraged subtype‐specific gene expression ranking information instead of absolute gene expression levels to address batch effects of diverse data sources.

Using Earley Parser for Verification of Totally Ordered Hierarchical Plans
Proceedings of the International Florida Artificial Intelligence Research Society ConferenceHierarchical planning extends classical planning by capturing the hierarchical structure of tasks via decomposition of tasks to subtasks. Hierarchical plan verification is the problem of determining whether a given plan is valid according to that ...

A Parametric Hierarchical Planner for Experimenting Abstraction Techniques [PDF]
, 2003 This paper presents a parametric system, devised and implemented to perform hierarchical planning by delegating the actual search to an external planner (the "parameter") at any level of abstraction, including the ground one.

Learning to Plan Hierarchically From Curriculum [PDF]
IEEE Robotics and Automation Letters, 2019 We present a framework for learning to plan hierarchically in domains with unknown dynamics. We enhance planning performance by exploiting problem structure in several ways: (i) We simplify the search over plans by leveraging knowledge of skill objectives, (ii) Shorter plans are generated by enforcing aggressively hierarchical planning, (iii) We learn ...
