Relatively simple iterative procedures are developed for simulating the queue length distribution for transient bulk arrival, bulk service queues. The method allows the study of holding strategies where the length of time a vehicle is held can depend on both the length ofthe queue and how long...

The concept of social entrepreneurship as a characterization of social responsibility for business organizations has gained considerable popularity. There is growing belief in international development and donor communities that this form of for-profit activity might be the long-sought panacea...

We look at the problem of optimizing complex operations with incomplete information where the missing information is revealed indirectly and imperfectly through historical decisions. Incomplete information is characterized by missing data elements governing operational behavior and unknown cost...

We consider the problem of optimizing inventories for problems where the demand distribution is unknown, and where it does not necessarily follow a standard form such as the normal. We address problems where the process of deciding the inventory, and then realizing the demand, occurs repeatedly....

In this paper, we study a dynamic fleet management problem with uncertain demands and customer chosen service levels. We first show that the problem can be transformed into a dynamic network with partially dependent random arc capacities, and then develop a structural decomposition approach...

In the controlled ovarian hyperstimulation (COH) treatment, clinicians monitor the patients’ physiological responses to gonadotropin administration to tradeoff between pregnancy probability and ovarian hyperstimulation syndrome (OHSS). We formulate the dosage control problem in the COH...
