“…To address this network design problem with an expensive‐to‐evaluate objective function featuring nonconvexity, nonlinearity, and nonclosed form, simulation optimization (SO) or simulation‐based optimization has recently been investigated and advocated (Amaran, Sahinidis, Sharda, & Bury, ; Osorio & Bierlaire, ). When SO is applied to solve the TLP, existing methods can be classified into two broad categories of feedback control (Gu, Shafiei, et al., ; Simoni et al., ; Zheng et al., ; Zheng et al., ) and surrogate‐based optimization (Chen et al., ; Chen, Xiong, He, Zhu, & Zhang, ; Chen, Zhang, He, Xiong, & Zhu, ; Chow & Regan, ; Ekström, Kristoffersson, & Quttineh, ; He, Chen, Xiong, Zhu, & Zhang, ).…”
