In the recent years, location problems attracted a considerable attention in the scientific community and a large number of papers studying minsum and minmax location problems have been published (see [23, 26, 38–41, 43, 45, 49, 50, 57, 66, 68–70

This chapter serves as an introduction and aims to make this book as self-contained as possible. We introduce here basic notions from the convex analysis and give important statements on convex sets, convex scalar and vector functions. For readers in

For solving minmax location problems in Hilbert spaces Hi, i = 1, …, n, numerically by proximal methods we present in this chapter first a general formula of the projection onto the epigraph of the function h : H1 × … × Hn → ℝ, defined by \

The goal of this chapter is to consider an optimization problem with geometric and cone constraints, whose objective function is a composition of n + 1 functions and to deliver a full duality approach for this type of problems.

Duality statements are presented for multifacility location problems as suggested by Drezner Hiu 1991, where for each given point the sum of weighted distances to all facilities plus set-up costs i...

In the framework of conjugate duality we discuss nonlinear and linear single minimax location problems with geometric constraints, where the gauges are defined by convex sets of a Frechet space. The version of the nonlinear location problem is additi

In this paper, we consider an optimization problem with geometric and cone constraints, whose objective function is a composition of $$n+1$$ functions. For this problem, we calculate its conjugate dual problem, where the functions involved in the obj
