Research on Bilateral Multi-attribute Automatic Negotiation Based on Multi-objective Genetic Algorithm ——A Logistics Company in Purchasing Negotiation [PDF]
, 2016 采购谈判是企业活动中很重要的一环，越来越多的企业管理者开始关注。现在很多的采购谈判都是一个买家，多个卖家，而谈判的属性又不单单是价格这个单一的属性，还包括质量、保修期、交货期、运费等等多个属性。另外不同的商家对不同的属性的偏好又有所不同，所以买方与卖方进行谈判时，一般的采购谈判需要各方人员参与谈判全过程，这样人员的占用导致了资源的耗费，时间的消耗也影响了企业运作的收益。而且传统谈判对谈判方的谈判技巧要求很高，如果一方谈判技巧不好，最后的谈判效果很不理想；传统的谈判还要在特定的时间，特定的地点进行 ...

Integrative Conservation, Volume 4, Issue 4, Page 665-674, December 2025.Using a diagnostic mitochondrial marker gene, we document the presence of furry‐eared dwarf lemurs, a species known from Madagascar's eastern montane rainforests, in several forest fragments across the island's central highlands. These findings raise new questions about when this species colonized these sites, how they tolerate these changing and ...

A genetic algorithm based optimization system for active frequency selective surface reconfigurable antenna [PDF]
, 2016 二十一世纪通信和信息技术迅猛发展。当前，智能天线在无线通信技术中的应用越来越广泛。智能天线系统极大的提高了无线通信系统的容量和稳定性，并使得空分多址成为可能，同时又可以大大的降低无线信号对空间的污染。因此，智能天线的发展，已成为无线移动通信技术发展很重要的一个方向。相对于自适应阵列系统来说，利用可重构天线实现的智能天线系统具有明显的成本优势。然而其性能仍有待提高。目前的性能缺点主要有两种：常见的可重构天线的增益较低，且难以实现低零深。在通信应用中较低的增益不利于降低系统功耗 ...

A Study on Sequencing Problem of Mixed-model Assembly Lines in Company Y Based on Genetic Algorithm [PDF]
, 2016 混流装配线通过对装配生产线的合理组织与排产优化，实现多品种共线装配，以较快的响应速度向客户提供定制的产品和服务。客车需求的多样化和客车市场的细分化，使得混流装配线成为Y公司普遍采用的一种生产方式。由于混流装配线复杂的装配过程会涉及不同的产品以及品种繁多的物料，因此，Y公司在努力改善其生产物流系统，以使混流总装线的运行更加平稳和高效。 本文在此背景下，以Y公司承装车间的Z总装线为研究对象，对其建立排序优化模型并利用遗传算法进行求解。首先，从装配流程和生产规划两方面分析Y公司总装线的管理现状 ...

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition
Antipode, Volume 57, Issue 3, Page 830-861, May 2025.Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.
