针对遥感目标检测而言,因其主要是分布密集的小目标从而导致在检测过程中存在漏检误检的情况,其次在检测中还会受目标尺度差异显著和检测背景复杂带来的影响,因此提出一种改进YOLOv7的目标检测方法。通过结合全局语义信息与局部语义信息的思想,利用集中特征金字塔CFP(centralized feature pyramid)解决遥感图像因目标分布密集以及检测背景复杂导致检测效率较低的问题;针对遥感图像中的小目标分布不定并且其特征表现能力不足从而在检测过程中容易存在漏检、误检的现象,因此,通过引入混合注意力模块ACmix加强网络对于小目标检测的敏感度,以提升对小目标的检测精度;使用WIOU损失函数来优化原网络中的损失函数,提升网络对检测目标的定位能力。在公开的遥感数据中进行实验对比,改进后的网络对于三个检测目标飞机、油罐、操场的mAP分别提升了0.068、0.061、0.098,实验结果表明,在检测背景复杂,检测目标密集分布的情况下,改进的YOLOv7网络性能有所提升。

为将可持续发展纳入制造业供应链决策,利用企业信息资源有效平衡其三重底线,基于绿色供应链CITI指数提出一种对经济效益、环境污染和社会责任进行整体协调,促进三者平衡发展的制造业可持续供应链网络模型,并研究了一种高效的进化求解算法。首先基于经济侧、环境侧和社会侧的八项指标,构建了一个多层次、多产品类型和多能源模式的混合整数线性模型,提出了将多个优化目标进行标准化整合的方法。然后,设计了供应链网络的多叉树结构表征,在此基础上提出了一种自适应多叉森林进化算法,并通过自适应参数调整显著提升了算法的求解精度。最后,基于制造业真实数据进行了大量仿真实验,验证了所提模型和算法的有效性和优越性。实验结果表明,仅升高5%以内的成本,企业即可使碳排放量平均降低17.67%、废气排放量平均降低10.54%、废水排放量平均降低13.05%、固体废物排放量平均降低20.19%。
