Description
Summary:This paper deals with the semi-fair emergency system design problem with reliable and failing service centers, in which the request of equal accessibility is taken into account. Within this paper, we introduce a semi-fair approach, which is based on the combination of so-called min-sum optimal design and the lexicographic min-max optimal design. It follows the idea of replacing a portion of less preferred levels of the lexicographical min-max optimization by one min-sum optimization process. The radial formulation of the problem was used as a basic concept of solving technique. We study two possible approaches from the point of computational time necessary for the semi-fair emergency system design and the price of fairness.
