Jonathan Bard and Yufen Shao from the University of Texas at Austin and Ahmad Jarrah from George Washington University investigate the problem of providing mobile rehabilitative services to patients residing in nursing homes, assisted living facilities, medical lodges and individual residences spread over a wide geographic area in their paper titled, 'The Therapist Routing and Scheduling Problem.' University of Michigan researchers, doctoral student Soroush Saghafian, now an assistant professor at Arizona State University, and associate professor Mark P. Van Qyen, investigated the benefits and costs of implementing strategies that include monitoring unreliable/risky suppliers and reserving capacity with a flexible backup supplier. Doctoral student Farid Mardin and Professor Takeshi Arai, both of Tokyo University of Science, in their paper, 'Capital Equipment Replacement under Technological Change' propose a method that minimizes the total discounted cost of two consecutive replacements with an effective annual discount rate.
