The present paper explores a Greek case study on optimizing the design of aviation networks under Public Service Obligations (PSO). Based on previous research on airline PSO networks applied to the case studies of the Azores and Norway, optimization models are adapted to minimize not only the cost to the airline, but also the total social costs. Different predictive models to estimate demand are developed and included in the optimization models. It is found that after applying the developed demand and optimization models, the total network costs can be reduced significantly, compared to the actual network's operation ranging from 4% to 20%.

在公共服务义务（PSO）下设计航空网络：以希腊为例

本文探讨了在公共服务义务（PSO）下优化航空网络设计的希腊案例研究。基于先前对应用于亚速尔群岛和挪威案例研究的航空公司PSO网络的研究，对优化模型进行了调整，不仅可以最大程度地降低航空公司的成本，而且可以降低总的社会成本。开发了用于估计需求的不同预测模型，并将其包括在优化模型中。可以发现，应用开发的需求和优化模型后，与实际网络的运营范围从4％到20％相比，可以显着降低总网络成本。
