The security and schedule management of an aircraft system has become much more important and very complicated issue because of information age's advances to solve this complication. We are using fuzzy soft set with the decision-making problem in aircraft system. This research uses the Fuzzy Soft Set Decision-Making Method (FSS_DMM) to determine the weight of assessment criteria and to synthesize the score of aircraft. This concept is used to acquire the complete performance value for each alternative, to make the final choice. © 2019 Association for Computing Machinery. All rights reserved.
