Lehigh’s Industrial and Systems Engineering (ISE) Council will be holding their sixth ISE Career Fair on September 16, 2015, a day before the Lehigh University Career Fair on... Read More
In this talk, we will present our recent work on two fundamental optimization problems in electric power systems, namely the optimal power flow (OPF) problem and the unit commitment (UC) problem. The first one is highly non-convex, and the second one is subject to significant uncertainty. In the first-part of the talk, we will present three strong second-order cone... Read More
We consider distributionally robust (DR) single-server scheduling problem variants with a fixed sequence of appointments with random no-shows and service durations. The joint probability distribution is ambiguous and only the support and first moments are given. We study
DR models that incorporate the worst-case expected cost and the worst-case CVaR of waiting,... Read More
In this talk, we consider two online optimization problems. The first one is the online linear programming problem. In this problem, the underlying optimization problem is a linear program, however, its constraint matrix is revealed column by column along with the corresponding
objective coefficient and a decision variable has to be set each time a column is... Read More
MOPTA aims at bringing together a diverse group of people from both discrete and continuous optimization, working on both theoretical and applied aspects. There will be a small number of invited talks from distinguished speakers and contributed talks, spread over three days. Our target is to present a diverse set of exciting new developments from different optimization... Read More
Wing shape is a crucial characteristic that has a large impact on aircraft performance. Wing design optimization has been an active area of research for several decades, but achieving practical designs has been a challenge. One of the main challenges is the wing flexibility, which requires the consideration of both aerodynamics and structures. To address this, the... Read More
We consider a Poisson hail on an infinite d-dimensional ground. In other words, there is a Poisson rain of “hailstones” of a random size (height+width). In the case of a cold ground, we analyze conditions for at most linear growth. In the case of a hot ground (hailstones are melt when touch the ground), we are interested in stability conditions. In the case of a mixed... Read More

Inventory Control in Assemble-to-Order Systems with Identical Lead Times: Lower bound, Control Policies, and Asymptotic Analysis
Assemble-to-order (ATO) is a widely-adopted supply-chain strategy to facilitate product variety, mitigate demand forecasting error, and enhance the overall efficiency of a manufacturing process. A general ATO inventory system serves... Read More
This paper discusses a number of important spatial optimization problems, including path routing and location planning, highlighting how they have evolved from simplified expressions to more advanced formalizations. Computing, enhanced data and GIS (geographic information systems) are shown to be central in this evolution. Trends suggest continued advancement, but also... Read More
