A mathematical multi-objective model for supply chain material requirements planning using Lexicograph Solution (the Topo beverage company)

Abstract

The materials requirement planning is considered one of the major systems in material planning in production management section of the companies. In supply chain, the material requirement planning system (MRP) is used in product management process in order to supply material. The aim of this article is to propose a multi-objective mathematical model in material requirement planning of the Topo Aloe vera beverage company. A linear programming model, having two objectives is proposed in this article and the required data to write and to test the model is gathered from Topo Company. In this paper, the proposed model is solved using the lexicographyy model and after modeling the problem, the model is run using the MATLAB software, and the obtained results are analyzed and the optimum values of objective functions and the decision variables of the model are determined.
