We develop an optimal control model to maximize the net value provided by a software system over its useful life. The model determines the initial number of features in the system, the level of dynamic enhancement effort, and the lifetime of the system. The various factors affecting these...

Information delays exist in an inventory system when it takes time to collect, process, validate, and transmit inventory/demand data. A general framework is developed in this paper to describe information flows in an inventory system with information delays. We characterize the suffcient...

Operations Management (OM) has evolved to its current status due to the contributions of researchers in many fields including economics, finance, behavioral sciences, operations research/management science, mathematics, statistics, and computer science. Many of these contributors are Nobel...

Environmental and energy independence concerns lead to government subsidies for electric vehicles (EVs). Operational decisions for a government are i) to incentivize EV ownership by a direct consumer subsidy, a station subsidy that reduces charging inconvenience, or by both subsidies; and ii) to...
