Two-criteria optimisation problem related to laparoscopic ventral hernia repair is formulated in this paper. An optimal implant from a given set and its orientation is sought. The implant is subjected to kinematic extortions due to a patient's body movement and intra-abdominal pressure. The first criterion of the optimisation problem deals with the reaction force in the implant fastener, while the deflection of the implant constitutes the second criterion. A two-stage optimization procedure is proposed and the optimal solution is determined with the aid of minimization of an additional objective function. Numerical examples for typical locations of hernia are provided.
本文提出了与腹腔镜腹疝修补相关的双准则优化问题。要从给定的一组植入物中寻找最优植入物及其方向。由于患者身体运动和腹内压，植入物会受到运动扭曲。优化问题的第一个准则涉及植入物紧固件中的反作用力，而植入物的挠度构成第二个准则。提出了一种两阶段优化程序，并借助最小化一个附加目标函数来确定最优解。还提供了疝典型位置的数值示例。
