具有主要参与者的线性二次平均场社会Optimization

Linear-Quadratic Mean Field Social Optimization with a Major Player

Minyi Huang, Son Luu Nguyen

摘要:

考虑了一个主要参与者和大量次要参与者的线性二次型(LQ)平均场控制问题,其中动态和成本依赖于随机参数。我们的目标是优化社会成本作为分散信息下的个人成本的加权和。将团队决策论中的逐人最优性原理应用于有限总体模型,构造了两个极限变分问题,其解满足一致平均场近似的要求,得到一个正倒向随机微分方程(FBSDEs)系统.我们证明了FBSDES解的存在唯一性,并在原大但有限总体模型中得到了接近社会最优的分散策略。

英文摘要:

This paper considers a linear-quadratic (LQ) mean field control problem involving a major player and a large number of minor players, where the dynamics and costs depend on random parameters. The objective is to optimize a social cost as a weighted sum of the individual costs under decentralized information. We apply the person-by-person optimality principle in team decision theory to the finite population model to construct two limiting variational problems whose solutions, subject to the requirement of consistent mean field approximations, yield a system of forward-backward stochastic differential equations (FBSDEs). We show the existence and uniqueness of a solution to the FBSDEs and obtain decentralized strategies nearly achieving social optimality in the original large but finite population model.
