Feryal Erhun received her Ph.D. in Business Administration, with a concentration in Production and Operations Management from the Graduate School of Industrial Administration, Carnegie Mellon University in 2002. She holds a B.S. and a M.S. in Industrial Engineering from Bilkent University, Turkey. She was a faculty member in the Management Science and Engineering Department of Stanford University from 2002 until 2013.

Feryal investigates foundations of contemporary problems in operations management (OM) and use them to develop solutions to practical engineering problems. Her research interests are in the strategic interactions between stakeholders in supply chains. In this context, Feryal has studied topics related to supply chain contracting, capacity, and inventory decisions. More recently, she has turned her attention to socially responsible operations: today, both for?profit businesses and nonprofit organizations aim to create the highest value for their shareholders, employees, partners, and the environment. Her research on nonprofits, healthcare OM, and sustainable supply chains has informed the development of theory addressing the unique challenges arising for these organizations and has extended traditional OM theory to these new and important settings.

Feryal is a strong proponent of practice-based research. Through collaborations with Intel Corporation, Cisco, Stanford University Medical Center, etc., she has been able to combine her academic interests with firms? needs to deliver insights for both communities. Recently, her research group has designed a decision-support system for optimizing capital investment decisions for firms in capital-intensive industries in collaboration with Intel Corporation. This work has been selected as one of the finalists in the 2012 Franz Edelman Award, which recognizes outstanding examples of innovative operations research that improves organizations, and Feryal has been inducted as an Edelman Laureate. Feryal is a recipient of 2006 NSF CAREER Award with her project titled ?Moving from Risks to Opportunities: An Exploratory Study of Risk Management in Supply Chains.?

  • Age of blood as a limitation for transfusion: potential impact on blood inventory and availability TRANSFUSION Fontaine, M. J., Chung, Y. T., Erhun, F., Goodnough, L. T. 2010; 50 (10): 2233-2239


    Evolving concerns about storage lesions for red blood cells (RBCs) have led to ongoing trials evaluating the benefits of transfusing fresher blood to acutely ill patients.We evaluated several RBC maximum shelf lives (MSLs) and their impact on RBC availability and outdate rate. First, we determined the mean age of the RBC units in our inventory by analyzing the data set of 18,987 nonirradiated RBC units transfused at our institution from April 2008 to March 2009. Second, we determined the feasibility of issuing RBC units of a designated age to patients using the same data set. We defined six scenarios where RBC units have different MSLs: Scenarios 1, 2, 3, 4, and 5 used a MSL of 7, 14, 21, 28, and 35 days, respectively. Scenario 6 used a combination of different MSLs depending on the category of patients.RBC units spent on average 8.6 days on the shelf with a mean age of 10.2 days at delivery and 18.8 days at issue for transfusion. Using the original 18,987 data points, we observed a shortfall in the availability of RBC units, decreased by 51, 20, 10, 4, 1, and 0% and an increase in the outdate rate to 3.2, 2.2, 1.0, 0.6, 0.4, and 4.5% for Scenarios 1, 2, 3, 4, 5, and 6, respectively, compared to baseline.Changing the MSL for RBC units would require novel approaches to RBC inventory management to meet hospital demands with acceptable outdate rates.

  • Improving platelet supply chains through collaborations between blood centers and transfusion services TRANSFUSION Fontaine, M. J., Chung, Y. T., Rogers, W. M., Sussmann, H. D., Quach, P., Galel, S. A., Goodnough, L. T., Erhun, F. 2009; 49 (10): 2040-2047


    Blood centers and hospital transfusion services are challenged with maintaining an adequate platelet (PLT) inventory to minimize the number of outdated units without risking a major shortage. A novel approach to inventory management was established at our institution through a collaboration between the Stanford University Medical Center (SUMC) Transfusion Service, the Stanford Blood Center (SBC), and the Department of Management Science and Engineering.An analysis of the supply chain performance between SBC and SUMC Transfusion Service was performed. First, the interaction between processes, such as blood collection, rotation, and inventory management, was studied. Second, changes were implemented based on the recommendations from the analysis team. Finally, a postanalysis was performed reflecting on the improvement of the operations between SUMC and SBC.A comprehensive data analysis of the PLT supply chain allowed the identification of three series of improvements to be implemented: 1) on SBC's PLT collection, 2) on SBC's rotation process, and 3) on the PLT inventory management policy at SUMC. A postimplementation analysis showed a reduction in the overall PLT outdate rate from 19% in the first quarter of 2006, down to 9% in the third quarter of 2008.A multidisciplinary effort among SUMC Transfusion Service, SBC, and experts in supply chain management resulted in a process improvement, which reduced the rate of PLT outdate at both SBC and SUMC Transfusion Service down to 9%, with a significant cost reduction of more than half a million dollars per year.
