In this paper we introduce the multi-period incremental service facility location problem where the goal is to set a number of new facilities over a finite time horizon so as to cover dynamically theâ€¦ (More)

In this paper we deal with two stationary loss queuing network location models. We analyze the influence of filtering policies on the locational aspect of the problems. We assume that requests forâ€¦ (More)

In this paper we consider a new class of continuous location problems where the ''distances'' are measured by gauges of closed (not necessarily bounded) convex sets. These distance functions do notâ€¦ (More)

In this paper, we deal with a facility location problem where we build new facilities or close down already existing facilities at two different distribution levels over a given time horizon. Inâ€¦ (More)

In this paper we analyze cooperative games whose characteristic function takes values in a partially ordered linear space. Thus, the classical solution concepts in cooperative game theory have to beâ€¦ (More)
