Workshop on Constraint Reasoning, Planning and Scheduling Problems for a sustainable future (GREEN-COPLAS)

The workshop will aim at providing a forum to discuss novel issues on planning, scheduling, constraint satisfaction problems (CSPs) to solve combinatorial problems that addressing environmental, economic, and societal challenges concerning sustainable development and a sustainable future. On the whole, the workshop will mainly focus on managing complex problems where planning, scheduling and/or constraint programming can be combined and/or interrelated, which entails an enormous potential for practical applications and future research. This edition will be mainly focused on planning and scheduling techniques for sustainable purposes.


The areas of AI planning and scheduling have seen important advances thanks to the application of constraint satisfaction models and OR techniques. Especially, solutions to many real-world problems need to integrate plan synthesis capabilities with resource allocation, which can be efficiently managed by using constraint reasoning techniques and OR techniques for solving sustainable combinatorial problems. COPLAS is ranked as CORE B in ERA Conference Ranking and it is covered in selected Elsevier database products.

We invite submissions on any topic relevant to the workshop, particularly those that combine techniques from both perspectives, planning & scheduling, and constraint programming. This includes but is not limited to:

  1. Planning:
    • Green planning
    • Constraint management
    • Temporal planning
    • Multi-criteria planning
    • Planning with resources
    • Reformulations to CSP
  2. Scheduling
    • Green Scheduling
    • Innovative models
    • Robust solutions
    • Energy efficient scheduling
    • Manufacturing
  3. Green planning and scheduling in Autonomous Greenhouse
  4. Integration of planning and scheduling,
  5. Heuristic and Metaheuristics techniques for green manufacturing.
  6. Hybrid CP and OR techniques for P&S,
  7. Real life applications for a sustainable future.

We are pleased to accept papers based on recent publications from other (non ICAPS) venues such as specialized conferences (CP, CP-AI-OR, AAMAS, …), or general AI conferences (AAAI, IJCAI, ECAI, …). This must be however clearly indicated in the submitted paper. Submission of papers that are under review in another forum is allowed and encouraged for wider dissemination as COPLAS will have informal proceedings only (but double check the submission conditions of the other conference).

In this edition, papers from the Autonomous Greenhouses International Challenge that uses intelligent planning and scheduling techniques are welcomed ( At least one author of each accepted paper must attend the workshop in order to present the paper. Authors must register for the ICAPS main conference in order to attend the workshop. There will be no separate workshop-only registration.

Submission Instructions

Papers must be prepared according to the instructions for ICAPS-20 (in AAAI format) available at and must be no more than ten (10) pages long, including figures and bibliography. Submitted PDF papers should be anonymous for double-blind reviewing and should be sent via the EasyChair conference system ( Every submitted paper will be reviewed by at least two members of the Program Committee. Late submissions must be consulted with the workshop organizers prior the submission deadline. Accepted papers will be included in the workshop notes. The best papers will be invited to be published in an International journal.
