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. In our specific
research, we study the design of multi-commodity flow networks,
production/distribution and closed-loop logistics networks, resilient
communications networks, sensor networks, and emergency response networks. 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.
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 methods, heuristic approximation algorithms, hybrid
methodologies, as well as stochastic modeling and optimization.
