This paper addresses the problem of linear-fractional programming under uncertainty. The uncertainty here is understood as ambiguity coefficients’ values in optimized functional. We give two mathematical formulations problem. In first one, refers to numerator: there are several sets objective function coefficients, each coefficient can determine numerator problem’s criterion at stage its soluti...
This paper aims to compare a two-echelon and a single-echelon distribution system. A mathematical model for the Single-Echelon Capacitated Vehicle Routing Problem (SE-CVRP) is proposed. This SE-CVRP is the counterpart of Two-Echelon Capacitated Vehicle Routing Problem (2E-CVRP) introduced in the authors’ previous work. The proposed mathematical model is Mixed-Integer Non-Linear Programming (MIN...
Several algorithms have been developed to solve the two-level linear programming problem during the past years. In this paper, we will formulate the mixed integer two-level linear programming problem and develop both the exact and heuristic solution procedures based on the branch-and-Lund technique for solving the problem. Computational experience and comparisons will be presented.
In this study, a bi-objective model for integrated planning of production-distribution in a multi-level supply chain network with multiple product types and multi time periods is presented. The supply chain network including manufacturers, distribution centers, retailers and final customers is proposed. The proposed model minimizes the total supply chain costs and transforming time of products ...
Optimizing the service card in multi-depot, multi-product and multi-level vehicle routing problem is one of the most important and at the same time, the most complex problems in the transportation problems contexts. Numerous exact heuristic and meta-heuristic algorithms have been developed for different vehicle routing problems. In this paper, a binary linear programming (BLP) based model for o...
