Pricing is an effective tool to control congestion and achieve QoS provisioning for multiple differentiated levels of service. In this paper, we propose a practical, flexible and computationally simple pricing strategy that can achieve QoS provisioning in Differentiated Services networks with multiple priority classes at close to peak efficiency, while also maintaining stable transmission rates...

We analyze hedge fund performance using the stochastic discount factor (SDF) approach and imposing the arbitrage-free requirement to correctly value the derivatives and dynamic trading strategies used by hedge funds. Using SDFs of many asset-pricing models, we evaluate hedge fund portfolios based on style and characteristics. Without the arbitrage-free requirement, pricing errors are relatively...

In this paper we consider a dynamic full truckload pickup and delivery problem with time-windows. Jobs arrive over time and are offered in a second-price auction. Individual vehicles bid on these jobs and maintain a schedule of the jobs they have won. We propose a pricing and scheduling strategy based on dynamic programming where not only the direct costs of a job insertion are taken into accou...

The last few years have witnessed a rapid growth in commoditization and consumption of IT services particularly due to the growing acceptance of cloud computing services. This in turn has led to newer forms of pricing the cloud services such as dynamic pricing. Infact, spot pricing, a dynamic pricing scheme has become mainstream. Cloud consumers using these schemes need to place their bids inor...

Pricing of communication services becomes a necessity once these services form a commodity in a market. As visible today, the Internet has dramatically made a move into its commercial deployment. Therefore, e.g. , Internet access, bandwidth, or services need to be charged for. However, there exist a number of pricing models – from static ones to highly dynamic ones – which need to be evaluated ...

In this paper, we present an approach to obstacle avoidance for a group of unmanned vehicles moving in formation. The goal of the group is to move through a partially unknown environment with obstacles and reach a destination while maintaining the formation. We address this problem for a class of dynamic unicycle robots. Using Inputto-State Stability we combine a general class of formationkeepi...

This paper proposes a hybrid approach to the problem of collision avoidance for indoor mobile robots. The DWA (short for: model-based dynamic window approach) integrates sensor data from various sensors with information extracted from a map of the environment, to generate collision-free motion. A novel integration rule ensures that with high likelihood, the robot avoids collisions with obstacle...

Rapid advances in hand-held computing and communication capabilities, decreasing cost of mobile devices, and emergence of standards are fuelling the growth of mobile distributed work arrangement (DWA) in business operations. However, mobile DWA is more than a technological arrangement; it is an organizational innovation that could involve structural and administrative changes in the organizatio...

E-tourism services open up new opportunities for businesses to expand and when possible to gain completive advantage. Dynamic pricing is an area of interest for both researchers and professionals. It’s the process of price specification in a way that best suits a tourism organization under certain circumstances that reflect its competitive environment. Many research studies have addressed dynam...

In an ad-hoc Grid environment where producers and consumers compete for providing and employing resources, trade handling in a fair and stable way is a challenging task. Dynamic changes in the availability of resources over time makes the treatment yet more complicated. Here we employ a continuous double auction protocol as an economic-based approach to allocate idle processing resources among ...
