通常，规划和配置蜂窝无线网络导致具有冲突目标的多目标优化问题，例如覆盖和成本。本文提出了一种在4G多跳中继网络中，通过联合基站和中继站的布置，将这些竞争对手组合在一个封闭的目标中，以最大化运营商利润的方法。相应的优化模型被描述为混合整数线性规划，并特别考虑了非协作中继模式下下行数据传输的有限带宽分配。我们提出了两种经济动机的选择方案，如何选择适当的权重来线性组合相互冲突的目标。此外，我们将所提出的优化模型应用于一个典型的计划场景，以数值分析权重变化的敏感度。
Generally, planning and configuring cellular radio networks lead to multi-objective optimization problems with conflicting objectives, e.g., coverage and cost. In this paper, we present an approach to combine those opponents in a closed-form objective for maximization of operator profit by means of joint base station and relay station placement in 4G multi-hop relay networks. The corresponding optimization model is formulated as mixed-integer linear program and particularly considers allocation of limited bandwidth for downlink data transmission in non-cooperative relaying mode. We suggest two economically motivated options how to choose appropriate weights for combining the conflicting objectives linearly. Furthermore, we apply the proposed optimization model to an exemplary planning scenario to analyze sensitivity to weight modifications numerically.
