Sensitivity analysis is used to quantify the impact of changes in the initial data of linear programs on the optimal value. In particular, parametric sensitivity analysis involves a perturbation analysis in which the effects of small changes of some or all of the initial data on an optimal...

Navigational systems assist drivers in finding a route between two locations that is time optimal in theory but seldom in practice due to delaying circumstances the system is unaware of, such as traffic jams. Upon arrival at the destination the service of the system ends and the driver is forced...

This paper analyzes how standards as a knowledge source are important for R&D, how significantly the (backward) citations by a patent of standard-related documents measure such knowledge flow, and how significantly they affect the performance of downstream R&D. Using both the RIETI inventor...

Open standard-setting organizations (SSOs) have emerged as important coordination and diffusion mechanism for information and communication technologies. Open standards are developed non-discriminatorily and licensed to anybody at reasonable and non-discriminatory terms. Little is known about...

Smartphone technology enables dynamic ride-sharing systems that bring together people with similar itineraries and time schedules to share rides on short-notice. This paper considers the problem of matching drivers and riders in this dynamic setting. We develop optimization-based approaches that...

Measurement plays a vital role in the creation of markets, one that hinges on efficiencies gained via the universal availability of precise and accurate information on product quantity and quality. Fulfilling the potential of these ideals requires close attention to measurement and the role of...

This paper proposes a risk assessment framework as a research road-map, with the aim of developing a protocol that integrates the risk management requirements from the perspectives of the business and the government. We take the viewpoint of value modeling and interpret the risk management...

Many enterprises that participate in dynamic markets need to make product pricing and inventory resource utilization decisions in real-time. We describe a family of statistical models that address these needs by combining characterization of the economic environment with the ability to predict...

This is the specification for the Power Trading Agent Competition for 2011 (Power TAC 2011). Agents are simulations of electrical power brokers, who must compete with each other for both power production and consumption, and manage their portfolios

Given the current risk environment, businesses are obligated to do their utmost to protect systems and ensure consumer confidentiality. Unfortunately, even the prudent and vigilant business entities may still be susceptible to data theft or other outside system intrusion. In this respect, sound...
