Transcript of SCPS Systems

Societal Cyber-Physical System
Lin Zhang, Associate Professor

Social Optimality
Under given overall resource constraints
Every individual collaboratively to reach a behavioral consensus such that
Social resources are sufficiently utilized
Personal utility are optimized

Nash Equilibrium
Selfish individuals compose a society lack of trust
Non-cooperative game reach an equilibrium such that
Nobody can improve his utility by changing only his own strategy
Nobody is satisfied
Resource are under utilized
How can we trigger evolving from the Nash Equilibrium to the Social Optimality?
