Call for Papers

ISORA-QTNA2020, the 14th International Symposium on Operations Research and its Applications (ISORA) and the 15th International Conference on Queueing Theory and Network Applications (QTNA) will be jointly organized by Asia-Pacific Operations Research Center (APORC) under APORS and the Operations Research Society of China (ORSC), to be held in Xi'an, Shaanxi Province in China, from August 19 (Wednesday) to 23 (Sunday), 2020.

Aim of the Conferences

ISORA is a series international symposium with goals to provide an international forum for scientists, researchers, educators, and practitioners in OR/MS to exchange ideas and approaches, to present research findings and state-of-the-art solutions, to share experiences on potentials and limits, and to open new avenues of research and developments, on all issues and topics related to the theories and applications of Operations Research. The previous ISORAs under the support of CAS and National Science Foundation of China (NSFC) were successful and attracted many international scholars.

The QTNA conference aims to promote the knowledge and development of high-quality research on queueing theory and its applications to networks and other related fields. The conference brings together researchers, scientists and practitioners from over the world and offers an open forum to share the latest important research accomplishments and challenging problems in the area of queueing theory, and network and related applications.
