Original abstract
In this paper, we deal with the set covering problem, which consists in finding the minimum number of service centres providing specialized services within a reasonable distance given by a threshold. However, we consider not only the threshold, but also weights of service centres so that the most important ones would not be omitted from the final solution. Since even the basic task without weights belongs to the class of NP-hard problems, stochastic heuristic methods must be used for large instances of the problem.
Czech abstract
V tomto příspěvku se zabýváme problémem pokrytí, který spočívá v nalezení minimálního počtu servisních středisek zajišťujících specializované služby pro všechny zákazníky v přiměřené vzdálenosti do dané horní meze. Avšak neuvažujeme pouze tuto prahovou hodnotu, ale také váhy servisních středisek tak, aby nejvýznamnější střediska nebyla vynechána z výsledného řešení. Protože dokonce i základní úloha bez uvážení vah patří do třídy NP-těžkých problémů, musí být použity stochastické heuristické metody pro velké instance problému.
