Welcome to My Page

 

I am PhD candidate in the Department of Industrial Engineering at Clemson University. My research interests lie in the areas of operation research and analytics. I am especially interested to develop optimization models and solution algorithms (prescriptive analytics) to deal with the challenging problems arising in the areas of supply chain managment and renewable energy production. My research has been published in peer reviewed journals such as IIE Transactions, Optimization Methods & Software, and International Journal of Advanced Manufacturing Technology.

Life cycle assessment and economics of biopower supply chains

In this study, we propose a bi-objective optimization model to investigate the economic and environmental impacts of integrating biopower and carbon capture and storage (CCS) strategies in power plants. Biomass cofiring in conjunction with CCS, known as Bio-CCS, is shown to be an effective approach to achieve large scale reductions in greenhouse gas (GHG) emissions from coal-fired power plants. However, the associated costs are often higher than using only the conventional CCS approach. Thus, in absence of the appropriate governmental support and incentives, power plants may not find Bio-CCS commercially attractive...

Analysing alternative incentive schemes to promote bioenrgy

We examine the impacts of governmental incentives for coal-fired power plants to generate renewable energy via biomass cofiring technology. The most common incentive is the production tax credit (PTC), a flat rate reimbursement for each unit of renewable energy generated. The work presented here proposes PTC alternatives, incentives that are functions of plant capacity and the biomass cofiring ratio. Following a resource allocation perspective, this study evaluates the impacts of alternative PTC schemes on biomass utilization and power plants' profit-earning potentials. The efficiency of these incentive schemes are evaluated by comparing with the results of utilitarian solution, an approach that finds a distribution of credits which maximizes the total profits in the system. To evaluate the fairness of the proposed schemes, the results of the max-min fairness solution is used as a basis.
