Airline seat inventory control is a very profitable tool in the airline industry. Mathematical programming models provide booking limits or bid-prices for all itineraries and fare classes based on demand forecasts. But the actual revenue generated in the booking process fails to meet...

The aim of this paper is to compare different environmental policies for cost-effective habitat conservation on agricultural lands, when the desired spatial pattern of reserves is a random mosaic. We use a spatially explicit mathematical programming model which studies the farmers' behavior as...

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...

This paper proposes a new hybrid algorithm Meta-heuristic for the problem of network planning systems. The main goal of this paper is, to develop an efficient optimization tool which will minimise the cost functions of the stated optimization problems in network planning systems. The following...

A HPS (hybrid power system) includes various sources of RE (renewable electricity) such as wind, solar, and biomass, and is supplemented by the public grid should the total RE supply is deficit to total demand. Given the operational capability of the total RE supply and the time-dependent demand...

The electricity market has since 1980s been gradually evolving from a monopoly market into a liberalized one for encouraging competition and improving efficiency. This brings the opportunity for generation companies (GenCos) to make more profits while embracing more risks of not being...

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...

With the increasing interest in decision support systems and the continuous advance of computer science, revenue management is a discipline which has received a great deal of interest in recent years. Although revenue management has seen many new applications throughout the years, the main focus...
