Method of Multi-agent Autonomous State Reconfiguration of Shipboard Chilled Water System

Abstract

Abstract:In consideration of the uncertainty of the modern ship environment and the requirements for the intelligence of integrated management of power platform, taking the shipboard chilled water system as the research object, the method of state reconfiguration based on the multi-agent autonomous decision making model with the existence of uncertainty was studied. The problem of state reconfiguration is formulated as a loosely coupled Markov decision process (MDP). Then the multi-agent autonomous decision making model based on MDP is established and the optimal policy is obtained by using genetic algorithm. Finally the performance of the optimal policy is examined in the numerical calculation and the autonomous state reconfiguration is realized by following the received policy. This method can increase the autonomous decision making level and enhance the mission effectiveness of shipboard chilled water system.
