The IAENG International Conference on Operations Research (ICOR'20) will take place in Hong Kong, 18-20 March, 2020. The conference ICOR'20 is held under the International MultiConference of Engineers and Computer Scientists 2020. The IMECS 2020 is organized by the International Association of Engineers (IAENG), a non-profit international association for the engineers and the computer scientists. The IMECS conferences serve as good platforms for our members and the entire engineering community to meet with each other and to exchange ideas. Our IMECS committees have been formed with over three hundred conference committees members who are mainly research center heads, faculty deans, department heads, professors, and research scientists from over 30 countries. The last IAENG conference has attracted more than eight hundred participants from over 50 countries. All submitted papers will be under peer review and accepted papers will be published in the conference proceeding.
