Ph.D. Research Topic:

My Ph.D. thesis, titled "Supply Chain Optimization," focuses on improvements in supply chain management through the use of concepts such as game theory, the price of anarchy, and stochastic optimization. My current work has two main areas: a theoretical approach to analyzing the competition and coordination in a two-channel supply chain, and a real-world problem optimizing a large-scale distribution network with parameter uncertainty.

In the first, I study competition and coordination in a supply chain in which a single supplier both operates a direct channel and sells its product through multiple differentiated retailers competing in quantities. Using analytical methods to find solutions in closed form, I show that the supplier generally prefers to have as many retailers as possible in the market. Further, I prove that many contracts known to coordinate a single-channel supply chain are insufficient to perfectly coordinate the two-channel supply chain and therefore propose a linear quantity discount contract and demonstrate its ability to coordinate the two-channel supply chain with symmetric retailers and improve the efficiency of the supply chain with asymmetric retailers.

In the second, the sponsoring company has funded research that would improve upon their existing distribution planning method. The large-scale nature of this problem, including over 800 uncertainties and 1200 decision variables, provided an opportunity for novel methods in solving this problem. I show that the existing method of using point-in-time data for all of the uncertain parameters produced a sub-optimal plan, and that stochastic optimization methods could improve upon this plan by lowering the expected total cost of production and distribution. Using chance constraint methods combined with a penalty cost for unfulfilled demand, I develop and implement an improved plan and provided a process for the company to use in future planning.
