Abstract

1-The aim of this study is to identify the optimum design of the air transport network between Sardinia /Continent, which at the same time meets the demand for mobility of the passengers by minimizing the costs of carriers in-service (frequencies and number of aircrafts). 2- The network object of this study is subject to PSO, or the connections between Cagliari and the main airports of the continent. The problem has been faced through a linear optimization model whose objective function responds to the maximization of the difference between revenues and total expenses of carriers. The constraints of the function are given by the Demand to satisfy and by the limits imposed by law in terms of PSO. 3- The expected result from the study is the conciliation of the "guarantee" for users' mobility and the strict rules of the market. In other words, we want to find a network configuration that meets the transport demand and at the same time it affords the companies a profit level for which they are more likely to offer a transport service to the peninsula. 4- The problem of territorial continuity between Sardinia and the Continent, or air connections governed under PSO, is a very topical issue. The research, which is part of this scenario, after several studies in which has been analyzed the phenomenon behind the optics of the demand, in this case wanted to examine all from the perspective of carriers, in order to find a balance between demand and supply.
