Modeling Sustainability In Renewable Energy Supply Chain Systems, Fei Xie
Modeling Sustainability In Renewable Energy Supply Chain Systems, Fei Xie
All Dissertations
This dissertation aims at modeling sustainability of renewable fuel supply chain systems against emerging challenges. In particular, the dissertation focuses on the biofuel supply chain system design, and manages to develop advanced modeling framework and corresponding solution methods in tackling challenges in sustaining biofuel supply chain systems. These challenges include: (1) to integrate 'environmental thinking' into the long-term biofuel supply chain planning; (2) to adopt multimodal transportation to mitigate seasonality in biofuel supply chain operations; (3) to provide strategies in hedging against uncertainty from conversion technology; and (4) to develop methodologies in long-term sequential planning of the biofuel supply chain …
Large-Scale Solution Approaches For Healthcare And Supply Chain Scheduling, Ridvan Gedik
Large-Scale Solution Approaches For Healthcare And Supply Chain Scheduling, Ridvan Gedik
Graduate Theses and Dissertations
This research proposes novel solution techniques for two real world problems. We first consider a patient scheduling problem in a proton therapy facility with deterministic patient arrivals. In order to assess the impacts of several operational constraints, we propose single and multi-criteria linear programming models. In addition, we ensure that the strategic patient mix restrictions predetermined by the decision makers are also enforced within the planning horizon. We study the mathematical structures of the single criteria model with strict patient mix restrictions and derive analytical equations for the optimal solutions under several operational restrictions. These efforts lead to a set …
Time-Driven Activity-Based Costing For Healthcare Provider Supply Chain Processes, Martha Isaura Gonzalez
Time-Driven Activity-Based Costing For Healthcare Provider Supply Chain Processes, Martha Isaura Gonzalez
Graduate Theses and Dissertations
In a time when healthcare costs continue to rise, nearly a third of hospital operating expenses are related to supplies, and the healthcare supply chain is complex, it is pertinent for healthcare providers to have a clear understanding of their healthcare supply chain process costs. Having a clear picture into how these costs are driven and where opportunities for cost reductions exist can support supply chain efficiencies. In this research, we develop a Time-Driven Activity-Based Costing (TDABC) supply chain cost management tool for healthcare providers. A TDABC management system can provide healthcare providers with valuable product and process supply chain …
