Bilevel optimization is a field of mathematical programming in which some variables are constrained to be the solution another problem. As consequence, bilevel able model hierarchical decision processes. This appealing for modeling real-world problems, but it also makes resulting models hard solve theory and practice. The scientific interest computational increased lot over last decade still gr...

The principal challenge of inventory control in supply chains is that the interacting autonomous enterprises have to plan their production and logistics under information asymmetry, driven by different, often conflicting objectives. In this paper, four different computational approaches are investigated to cope with this challenge: decomposition, integration, coordination, and bilevel programmi...

The aim of this study is to deal with a minimum cost network flow problem MCNFP in a largescale construction project using a nonlinear multiobjective bilevel model with birandom variables. The main target of the upper level is to minimize both direct and transportation time costs. The target of the lower level is to minimize transportation costs. After an analysis of the birandom variables, an ...
