Dynamic Intelligent Supply-Demand Adaptation Model Towards Intelligent Cloud Manufacturing

As a new mode and means of smart manufacturing,smart cloud manufacturing(SCM)faces great challenges in massive supply and demand,dynamic resource collaboration and intelligent adaptation.To address the problem,this paper proposes an SCM-oriented dynamic supply-demand(SD)intelligent adaptation model for massive manufacturing services.In this model,a collaborative network model is established based on the properties of both the supply-demand and their relationships;in addition,an algorithm based on deep graph clustering(DGC)and aligned sampling(AS)is used to divide and conquer the large adaptation domain to solve the problem of the slow computational speed caused by the high complexity of spatiotemporal search in the collaborative network model.At the same time,an intelligent supply-demand adaptation method driven by the quality of service(QoS)is established,in which the experiences of adaptation are shared among adaptation subdomains through deep reinforcement learning(DRL)powered by a transfer mechanism to improve the poor adaptation results caused by dynamic uncertainty.The results show that the model and the solution proposed in this paper can performcollaborative and intelligent supply-demand adaptation for themassive and dynamic resources in SCM through autonomous learning and can effectively performglobal supply-demand matching and optimal resource allocation.

A Study of Coordinating China's Two-Pillar Regulatory Policy under the Shock of the Fed's Interest Rate Hike-From the Perspective of"Stable Growth"and"Risk Prevention"

Domestic asset price fluctuations triggered by the impact of the Fed's interest rate hike may lead to a spiral of mutual feedback between fluctuations in real economy and systematic risks of the financial sector.By constructing a DSGE model of small-scale open economy including cross-border capital flows and supply-demand financial frictions,this paper describes the negative feedback mechanism formed by the interplay between domestic real-economy fluctuations and financial risks on both supply and demand sides under the impact of Fed's interest rate hike,and studies how to coordinate monetary policy and macroprudential policies under the goals of maintaining stable growth and preventing risks.
