21st International Conference on Operational Research - KOI 2026

Dear OR Society,

on behalf of Croatian Operational Research Society (CRORS) can you please forward this e-mail to your Society members.

Namely, we are organizing the 21^st International Conference on Operational Research - KOI 2026 which will be held 23-25 September, 2026 in Brela, Croatia (more details can be found at: https://hdoi.hr/koi-2026/).

We encountered some technical issues with our previous [email protected] (which is not in function any more) and advise you to send us any inquiry that you have (or had in the last month) regarding the conference to our new e-mail address: [email protected]. 

Call for Abstracts is coming soon (end of February 2026), but we are still waiting for the special sessions proposals.

We are kindly inviting you to propose special session for KOI 2026.

Proposal should include:

•    Title
•    Session subject (not more than 1 page)
•    Chair(s)

If you or any of your colleagues will be able to organize a special session, please let us know as soon as possible (no later than February 15) so we could announce the special session and include it for abstract submission at the web page.

We are looking forward to receiving the affirmative answer, and will be very pleased to have you at KOI 2026.

Thank you in advance for your cooperation and hope to see you soon!

Regards from Croatia!

Tea Šestanovi?, president of CRORS and co-chair of Program Committee
