چکیده
supplier selection and optimum order determination is one of the important components of production and logistics management for many companies . therefore , after selecting the appropriate supplier , the optimal ordering of each supplier should be obtained according to the goals and limitations of interest . one of the efficient methods in this regard is that the goal of this research is to design a multi - objective model to determine the optimal inventory level and allocation to each of the suppliers . this is done by designing a multi - objective model with the objectives of minimizing costs in the chain such as shopping costs , maintenance , etc. as well as maximizing the quality of materials purchased from suppliers . finally , a non - dominated sorting genetic algorithm is solved using multi - objective non - dominated sorting genetic algorithm . in order to validate the model , a modified constraint - constraint method is solved and the results are compared with the first method .
finally , in order to prove the appropriate performance of the proposed solution in the proposed model , these experiments were analyzed on the experimental data produced with different dimensions and the obtained responses were analyzed using statistical methods
