摘　　要：在应急供应链因各参与方之间的利润冲突而频繁失效的背景下,网络均衡理论常被用于构建应急供应链模型,以确保决策的稳定性。然而,现有模型的线性、单调、可导约束条件无法充分捕捉应急情境下的复杂决策行为,从而限制了模型在实际应用中的有效性和准确性。为了解决这个问题,我们提出了一个应急供应链网络均衡变分不等式模型,并创新性地使用非线性、非单调甚至非连续的函数作为模型的约束条件。通过设计案例进行模拟仿真,我们验证了该模型可以在复杂的非线性环境中,为各参与方提供符合其利润要求的稳定决策,显著提升了实际应用价值。In the context of frequent failures in emergency supply chains due to profit conflicts among partici-pants,network equilibrium theory is often used to construct emergency supply chain models to en-sure decision stability.However,existing models with linear,monotonic,and differentiable constraints fail to fully capture the complex decision-making behaviors in emergency situations,thereby limiting their effectiveness and accuracy in practical applications.To address this issue,we propose an emer-gency supply chain network equilibrium variational inequality model,innovatively using nonlinear,non-monotonic,and even discontinuous functions as constraints.Through designed case simula-tions,we verify that this model can provide stable decisions that meet the profit requirements of all participants in complex nonlinear environments,significantly enhancing its practical application value.
