An experimental analysis of the p-median problem under uncertainty: an evolutionary algorithm approach

López-Monzalvo, Francisco; Brizuela, Carlos A. - In: European Journal of Industrial Engineering 8 (2014) 4, pp. 554-578

Facility location under uncertain environments is an important and challenging problem. The problem deals with the optimal placement of facilities that serve a set of spatially distributed nodes. One way to deal with this problem is to model uncertainty by means of scenarios and to optimise some...
