- Title: Minimum Maximum Degree Publish-Subscribe Overlay Network Design
- Presenting Author: Dr. Andrea Richa
Abstract:
Designing an overlay network for publish/subscribe communication in a system where nodes may subscribe to many different topics of interest is of fundamental importance. For scalability and efficiency, it is important to keep the degree of the nodes in the publish/subscribe system low. It is only natural then to formalize the following problem: Given a collection of nodes and their topic subscriptions connect the nodes into a graph which has least possible maximum degree and in such a way that for each topic t, the graph induced by the nodes interested in t is connected. We present the first polynomial time logarithmic approximation algorithm for this problem and prove an almost tight lower bound on the approximation ratio. Our experimental results show that our algorithm drastically improves the maximum degree of publish/subscribe overlay systems.
We also investigate the problem of minimizing not only the maximum degree alone but also in conjunction with the average degree, giving the first parameterized algorithm that achieves nontrivial sublinear bounds for approximating both the average and maximum degrees. In addition, we propose a variation of the problem by enforcing that each topic-connected overlay network be of constant diameter, while keeping the average degree low. We present a heuristic for this problem which guarantees that each topic-connected overlay network will be of diameter 2 and which aims at keeping the overall average node degree low. Our experimental results validate our algorithm showing that our algorithm is able to achieve very low diameter without increasing the average degree by much.
This work in this talk was done in conjunction with Melih Onus, now at TOBB, Turkey, and appeared/will appear in INFOCOM 2009 and ICDCS 2010.

- Title: Moving Forward and Making a Difference: Research Priorities for the Science of Service
- Presenting Author: Dr. Mary Jo Bitner and Kevin A. Burkhard, MBA
Abstract:
Given the significant, sustained growth in services experienced worldwide, Arizona State University’s Center for Services Leadership embarked on an 18-month effort to identify and articulate a set of global, interdisciplinary research priorities focused on the science of service. Diverse participation from academics in a variety of disciplines working in institutions around the world—in collaboration with business executives who lead organizations ranging from small startups to Global 1000 companies—formed the basis for development of the priorities. The process led to the identification of the following 10 overarching research priorities:
Fostering Service Infusion and Growth, Improving Well-Being through Transformative Service, Creating and Maintaining a Service Culture, Stimulating Service Innovation,
Enhancing Service Design, Optimizing Service Networks and Value Chains, Effectively Branding and Selling Services, Enhancing the Service Experience through Cocreation,
Measuring and Optimizing the Value of Service, and Leveraging Technology to Advance Service.
In addition, for each priority, several important and more specific topic areas for service research emerged from the process. The intent is that the priorities will spur service research by shedding light on the areas of greatest value and potential return to academia, business, and government. Through academic, business, and government collaboration, we can enhance our understanding of service and create new knowledge to help tackle the most important opportunities and challenges we face today.

- Title: Real-time Decision Support System for Healthcare and Public Health and Emergency Services Sectors
- Presenting Author: Dr. Sunderesh Heragu
Abstract:
In this talk, we discuss the development of a real-time decision support system (RTDSS) for use by professionals in the healthcare and public health (HPH) and emergency services sectors (ESS) during and immediately after a pandemic influenza or other viral attack. HPH and ESS are two of 18 critical infrastructure and key resources sectors identified by the department of homeland security’s (DHS) Office of Infrastructure Protection (OIP). The RTDSS will address capability gaps identified by the HPH and ESS sectors. We will demonstrate a few of the tools that are being developed for use in the RTDSS. These include simulation models for mass vaccination clinics, throughput analysis of emergency departments in hospitals, mixed-integer models for location of facilities in the strategic national stockpile network and allocation of patients to hospitals during a pandemic attack.
