About

Hayriye Ayhan is a Professor in the H. Milton Stewart School of Industrial and Systems Engineering at Georgia Tech. Her research interests focus on stochastic (Max,+) linear systems, performance analysis of queueing and production systems via series expansions, and Markov decision processes with applications to admission control, inventory, and production control. Dr. Ayhan has made significant contributions to these areas, combining theoretical and applied approaches to improve understanding and management of complex industrial and systems engineering problems. Dr. Ayhan received her Bachelor's degree in Industrial Engineering from Bosphorous University and earned her Ph.D. in Industrial Engineering from Texas A&M University in 1995. She was honored with the National Science Foundation CAREER Award in 2000, recognizing her promising research trajectory and contributions to the field. She is an active member of the Institute of Operations Research and Management Sciences (INFORMS) and serves as the secretary and treasurer of the INFORMS Applied Probability Society, reflecting her leadership and commitment to the professional community in operations research and applied probability.

• Dynamic Control of Non‐Collaborative Workers When Reassignment Is Costly

  Production and Operations Management · 2021-11-06 · 5 citations

  articleSenior author

  Cross‐training is an important tool to improve the performance of manufacturing and service systems through dynamic worker allocation. This study investigates how cross‐training can be leveraged when worker collaboration is not possible and frequent worker reassignment is undesirable. We consider a tandem queueing system with finite buffers between tasks. We show that if each worker is the fastest at a different task, then the optimal policy is always dedicated, regardless of the magnitude of th…
