Optimal Control Strategies in Delayed Sharing Information Structures
The -step delayed sharing information structure is investigated. This
information structure comprises of controllers that share their information
with a delay of time steps. This information structure is a link between
the classical information structure, where information is shared perfectly
between the controllers, and a non-classical information structure, where there
is no "lateral" sharing of information among the controllers. Structural
results for optimal control strategies for systems with such information
structures are presented. A sequential methodology for finding the optimal
strategies is also derived. The solution approach provides an insight for
identifying structural results and sequential decomposition for general
decentralized stochastic control problems.Comment: Sumbitted to IEEE Transactions on automatic contro
Structural Results for Decentralized Stochastic Control with a Word-of-Mouth Communication
In this paper, we analyze a network of agents that communicate through the
``word of mouth," in which, every agent communicates only with its neighbors.
We introduce the prescription approach, present some of its properties and show
that it leads to a new information state. We also state preliminary structural
results for optimal control strategies in systems that evolve using
word-of-mouth communication. The proposed approach can be generalized to
analyze several decentralized systems
