Other works that implement MILPs include [21–27]. Fur-thermore, a mixed integer nonlinear programming (MINLP)formulation is proposed by [28], as the authors incorporate cer-tain dynamic aspects such as lead time and inventory positions.The resulting model is complex and that is why they implement asingle product single level network and solve it using a genetic algo-rithm (GA). Giri and Sharma [29] solve the problem with algorithmsdeveloped for sequential and global optimization.
