To operate efficiently as a regional society, I invite you all to attend a general meeting of ORGS (OR Group of Scotland) to discuss the following items:

• Election of the ORGS committee (Chair, Secretary, Treasurer, and Members-at-Large).
• Insights from current committee members & transfer of posts.
• Discussion of how ORGS should operate.

If you would like to serve in any particular role in the committee, please indicate your interest by noon, 26th October, to kerem.akartunali@strath.ac.uk, so that can be circulated to attending members.

Thanks for your interest, and looking forward to seeing you in Glasgow in few weeks.

Abstract

The inventory-routing problem jointly decides on inventory management issues and when and in what sequence to visit the customers in a supply chain. The aim is to minimize the system-wide inventory holding and routing costs of the supply chain. We consider several mixed integer program formulations of the problem and discuss computational advantages and disadvantages of these formulations. A branch-and-cut approach and a heuristic based on an a priori tour are presented to solve the problem. We provide our computational results about the branch-and-cut algorithm and the heuristic that perform better than their competitors in the literature.
