Multi-product distribution in multi-supplier combined and capacitated transport networks

Abstract

The paper tackles the problem of capacitated transport vehicle routing for the combined distribution of multiple products for multiple suppliers. This real-life urban distribution-planning problem requires a solution that identifies a set of routes for carrying out the combined distribution in extensive multi-supplier distribution networks. The paper describes the development of a novel 0-1 model for modelling the routing problem to aid in the optimum routes for the combined distribution with the objective of minimising the total distance travelled that significantly affects the transportation cost while satisfying demand and capacity constraints. For conducting a comparative analysis, the paper deploys a solution procedure that quickly leads to a good routing solution. The paper introduces a case study as an application scenario with three case problems for illustrating the suitability and applicability of the proposed approach. The results are not surprising; the novel 0-1 model provides optimal solutions and outperforms the solution procedure.
