methodology for safety stock placement in supply chain by using simulated annealing algorithm

in this paper, we introduce a methodology for safety stock placement in supply chain. the problem has two objectives: minimization of good's delivery time and inventory cost. because the problem belongs to np-hard category, we develop a proper simulated annealing algorithm (sa) for solve the proposed methodology in large scaled problem. for verify the performance and efficiency of the methodology is shown via a numerical example. the obtained results imply the efficiency of proposed methodology and the ability of developed simulated annealing algorithms for achieve to near optimal solution.
