Abstract: A cognitive decision support fleet management and maintenance decision system may comprise a first cognitive decision support system to process information regarding a plurality of platforms and generate a list of condition based response activities and a weighted ranking of the probability of success of each condition based activity. A second cognitive decision support system may be tasked by the first to, and configured to, provide a plurality of ranked courses of action. A third cognitive decision support system may be tasked by the second to, and be configured to, assess resource availability for each condition based response activity. The second cognitive decision support system may be further configured to generate from the list of condition based response activities and the resource availability assessment for each condition based response, a plurality of recommended courses of action for the platform. The courses of action may be weighted according to an order of preference in carrying out each.
