Research activities in the lab relate to effective and efficient design and operation of networked systems that provide consumers with products and services. These activities have three dimensions:


1. Effective modeling approaches for efficient design of large scale networked systems:

Complex and large-scale networked systems appear in the context of several practical settings. Each of these systems has its own specific operational and structural characteristics, and it is imperative to incorporate these characteristics into quantitative modeling for higher effectiveness. Thus, each networked system possesses both modeling and methodological challenges. Examples include emergency response networks, biomass/biofuel logistics networks, closed-loop supply chain networks, and wireless sensor networks.


2. Strategic and tactical decision making in networked systems, e.g., supply chains:

The decision problems that we study relate to product and service flow management via location, transportation, and product/service supply planning for the underlying networks; integration of location, transportation, product/service supply, and inventory decisions; and contractual issues in location, transportation, product/service supply, and logistics-service management.


3. Efficient optimization methodologies to support these design and decision problems:

The design and decision problems considered in the context of the above two dimensions dictate large-scale mathematical optimization models incorporating complex/interrelated nature of various components of the underlying networked systems. We study the associated trade-offs inherent in such design and decision making activities with a systems approach. Thus, the focus of the third dimension of our activities is to investigate efficient solution methodologies that support the analysis of these optimization models. The specific methodologies of interest include efficient exact optimization methods, heuristic approximation algorithms, hybrid methodologies as well as stochastic modeling and optimization.
