Despite the requirements to handle ever increasing numbers of aircraft, airports also have to meet environmental targets and regulations. The complexity of the problems increases the closer an airport has to work to its maximal possible capacity. The complexity of the problems also mean that advanced decision support systems are needed to guarantee efficient airside airport operations and to mi...

Directed Technologies, Inc. has completed three analysis projects for the hydrogen program office during the past year: a detailed mass production cost estimate for stationary proton exchange membrane (PEM) fuel cell systems, an assessment of the costs of producing electricity from stationary fuel cells for buildings with hydrogen and heat cogeneration, and a preliminary assessment of the use o...

During the last two decades the European airport industry is liberalised and turned to competitive market environment. This fact attracts an increasing scientific and practical interest to analysis of airport efficiency and its determinants, as well as different aspects of airport competition. This paper contains a critical review of existing researches in these two areas – airport efficiency a...

Security at major locations of economic or political importance is a key concern around the world, particularly given the increasing threat of terrorism. Limited security resources prevent full security coverage at all times, which allows adversaries to observe and exploit patterns in patrolling or monitoring, e.g. they can plan an attack that avoids existing patrols. An important method of cou...

We introduce a new framework of Airport and Railway Problems, which combines capacitated facility location with network design. In this framework we are given a graph with weights on the vertices and on the edges, together with a parameter k. The vertices of the graph represent cities, and weights denote respectively the costs of opening airports in the cities and building railways that connect...

Airport buildings are among the complex and unique of contemporary century. Their importance lies in fact that they represent city’s gateway to whole world. Employing local architecture elements is one design ideas used passenger at airports, allowing recipient (traveler) define urban identity city history culture, she indicated. There have been many proposals about mechanism employing building...

background: noise is one of the harmful factors of industrial environments that may cause defect such as hearing defects, high blood pressure, irritation, sleep disturbances, increased respiratory rate and oxygen consumption. the residents and personnel working in industries around mehrabad airport continuously exposed to noise pollution caused by the traffic of passenger, war and training airp...

Airport facilities are places where constantly updated measures, regulations and improvements implemented. Simulation modeling plays an important role in ensuring the high efficiency user friendliness of such arrangements. Especially recent years, simulation has become indispensable need for aviation industry. Contrary to traditional theories, approach reveals a more realistic system behavior a...
