Brazil uses taxes, subsidies, and blending mandates as policy instruments to manage its transportation fuel markets. Despite all the market stabilization efforts, the fuels sector has been very dynamic in recent years. In response to ethanol supply fluctuations, the ethanol blending rate is...

There are several factors that necessitate the use of bicycle as a non-motorized transportation vehicle. Some of these factors include: Increase of the air pollution, many vehicles traveling simultaneously and creating massive traffic in the urban streets, decrease in the citizens’ physical...

This paper deals with forest trade modelling from a theoretical, analytic and empirical perspective. An integrated dynamic log-lumber trade model is developed and then used to examine two trade issues, namely, a reduction of Russian taxes on log exports and removal of the taxes on Canadian...

One of the main points of criticism on academic research in operations research (management science ) is that there is too much emphasis on the mathematical aspects of the discipline. In particular, the mathematical models that lend themselves to rigorous mathematical analysis are often rough...

Abstract This paper studies decision rules for accepting reservations for stays in a hotel based on deterministic and stochastic mathematical programming techniques. Booking control strategies are constructed that include ideas for nesting, booking limits and bid prices. We allow for multiple...

Forest product trade analysis is complicated by the inter-relationships among forest products. This paper deals with the development and application of an integrated log-lumber trade model that divides the globe into 20 regions. These regions play a significant role as producers and/or consumers...

The optimal placement of turbines in a wind farm is critical to the maximization of power production. In this paper, we develop a new mathematical programming approach for wind farm layout optimization. We use Jensen's wake decay model to represent multi-turbine wake effects. We develop mixed...

This paper aims to design a system that can enable optimal operation of the solar powered Membrane Distillation Bio-Reactor (MDBR) water recycling plant. Optimal operation is described as maximization of the clean water produced while being a self sufficient entity in terms of energy. During...

Fossil fuels still constitute an important source of energy in the world, but they need to comply with more strict environmental requirements. The coal industry, the basic primary energy supplier to the Polish economy, not only faces new environmental regulations but also restructuring and...
