 +Title: Decision-making in Decentralized Systems
  
 +Abstract: Decentralized systems are ubiquitous in the modern world. Communication systems, sensor networks, ​ power generation and transmission systems, supply chain networks, economic systems like markets ​ and auctions are all examples of decentralized systems. Such systems are characterized by the presence of multiple decision-making agents with different information. In this talk, I focus on the problem of finding optimal decision-strategies for co-operative agents in a decentralized system. In particular, I consider a decentralized stochastic decision-making problem ​ with  multiple decision-makers ​ that share information with each other with a fixed time delay. Such decision problems arise in queuing networks, wired communication networks, distributed control systems, surveillance systems etc.  In spite of initial conjectures as early as 1971, finding the general structure of agents'​ optimal decision-strategies with delayed information sharing had remained an open problem ​ for 40 years. My research provides a conceptual framework that not only identifies the structure of optimal decision strategies but also provides a sequential decomposition of the optimization problem. Moreover, the conceptual methodology developed here is shown to be  applicable to a broader class of decentralized decision making problems as well.
