General Information

I am pleased to announce our next INFORMS meeting, Wednesday Sept. 25th at the University of Texas, ETC 5.132, from 6:30-8:30 PM. Our speaker will be Erhan Kutanoglu of the OR department. His abstract can be found below.

The ETC building is at the corner of San Jacinto and Dean Keeton, across a raised walkway from the Engineering School (ECJ) and Robert Lee Moore
Hall (RLM). http://www.utexas.edu/maps/main/areas/engineering.html

Before the talk, we'll have a short discussion of new business, including a proposal to start a job-search support group -- perhaps
meeting every week at a coffee shop to exchange ideas. If you have other new business, bring it up then or let me know in advance.

For those who don't know, we plan to sponsor a Simulation Symposium in February or March. If any of you have ideas for that -- topics, locations, speakers, etc. -- please e-mail them to me. Those of you who mentioned various ideas at the banquet need to jog my pitifully inadequate memory.

Again, please join us Sept. 25th for an informative talk by Assistant Professor Kutanoglu of the OR Department at UT.

Pizza, drinks, and other refreshments will be served.

Topic: "Analysis of Multi-dimensional Coordination Problems in Service Parts Logistics Systems"

Abstract:

Motivated by recent challenges in real service parts logistics (SPL) systems, we present new research focused on models and algorithms for
coordination problems in SPL. The challenge in SPL systems is to coordinate decisions across business units, time horizons, and geographical locations simultaneously towards high-quality system-wide solutions. We first develop a unified framework for integrated logistics network design and inventory management and explore decomposition-based solution methodologies for the associated problems formulated as mathematical models. The logistics network design submodel involves multiple echelons, multiple products and time-based service coverage restrictions. The inventory submodel involves inventory sharing across multiple facilities and response-time based service levels. Motivated by the scale of the problems existing in real SPL systems, we also investigate multiple levels of granularity of the models and decomposition techniques, and undercover the trade-offs between computational burden and solution accuracy. We finally address
the mechanism design and incentive issues that inherently exist in coordination problems: How do we make sure that decision entities, each responsible for a segment of the overall problem, have the necessary incentives to coordinate their decisions?
