经典管理学理论以逻辑实证主义的解释式研究为基础。然而,作为解释式研究前提的“假说演绎”,不仅存在虚无假设检验的逻辑层面问题,而且由于数据建模方式的局限性以及在数据利用方面的有限性,极大限制了其解释能力,尤其是在大规模和个性化的环境中难以提供精准解释和理论指导。数智时代的到来使管理学的研究方法发生深刻改变,数智化发展不仅产生了大规模、实时性数据,而且随着生成式人工智能的崛起,数据分析、机器学习和模型构建能力得以飞速发展,从而使实时科学决策成为可能。智能革命、人工智能的技术发展同社会科学的深度融合,为预测式研究提供了良好条件和巨大潜力,管理研究方法正经历一场由解释向预测的转型与迭变。

针对多个综合能源服务商(IESP)协同运行中的能源交易问题,在考虑系统内风光不确定性问题的前提下,通过配电网运营商(DSO)制定电价,并协调IESP联盟的购、售电计划以及IESP成员之间的能源交互计划。以典型风光场景的历史出力数据为基础,以综合范数为约束条件,提出基于数据驱动的IESP联盟分布鲁棒优化调度模型。构建以DSO为上层领导者、IESP联盟为下层跟随者的主从博弈模型以及以下层IESP联盟为主的合作博弈模型;在下层IESP联盟中建立氢能系统模型,并考虑需求响应与碳交易机制;基于纳什谈判理论将合作博弈模型分解为联盟成本最小化问题与支付效益最大化问题。结合二分法、列与约束生成算法、交替方向乘子法对模型进行求解。算例结果表明:相较于传统的主从博弈模型,所提混合博弈模型能够实现IESP联盟的联合运行成本最小化,所建氢能系统能有效地减少碳排放,具有良好的经济效益;IESP联盟基于各成员的贡献大小实现了合作收益的公平分配。

The ZrTiON gate-dielectric GaAs metal-oxide-semiconductor （MOS） capacitors with or without ZrAION as the interfacial passivation layer （IPL） are fabricated and their properties are investigated. The experimental results show that the GaAs MOS capacitor with the ZrAION IPL exhibits better interracial and electrical properties, including lower interface-state density （1.14 × 10^12 cm^-2eV^-1）, smaller gate leakage current （6.82 × 10^-5 A//cm^2 at Vfb ＋1V）, smaller capacitance equivalent thickness （1.5 nm）, and larger k value （26）. The involved mechanisms lie in the fact that the ZrAION IPL can effectively block the diffusion of Ti and O towards the GaAs surface, thus suppressing the formation of interracial Ga-/As-oxides and As-As dimers, which leads to improved interracial and electrical properties for the devices.

In social networks, the most studies focus on the trust prediction, but distrust cannot get enough attention. The distinct characteristics of distrust relations present challenges to traditional relation *** relations are very sparse in social network,and negative interaction data is too little. We embark on the problem to investigate the distrust prediction with only network topology. After achieving seven social distrusting-inducing factors, we adopt machine learning and optimization methods to model the prediction *** framework of Distrust prediction in Signed social network(DP-SSN) is proposed, which can predict distrust relations without any interaction data. Empirically, we perform extensive experiments on real-world data to corroborate the effectiveness of the proposed framework.
