Application Of Interval Multiple Attribute Decision Making In Armor Weapon System-of-systems Effectiveness Evalution

Evaluation of operational effectiveness for weapon system-of-systems (SoS) is one of the basic issues in weapon SoS research, it's also the principal base of the optimization of weapon SoS. Combat simulation is an effective method for Weapon SoS effectiveness evaluation, but it's lacking system theory to analyze and process the simulation result data. Due to the complexity and uncertainty of real world and mistiness of human thought, people usually prefer to produce the decision information in the form of interval numbers, not the precise numerical.The paper focuses on the study of the theory and methods for interval multiple attribute decision making (IMADM) and it's application in weapon SoS effectiveness evaluation. According to the requirement of SoS operation effectiveness evaluation, the model and the algorithms for IMADM have been studied and improved. Based on the application of IMADM in weapon SoS effectiveness evaluation, a concepts on interval numbers orientation-distance is introduced, a improved method of normalizing the interval numbers decision matrix and a method of ascertaining attribute weight have been proposed. Then, three basic decision-making models are studied emphatically in the paper, provide a workable method to weapon SoS effectiveness assessment.The paper has dicussed the design and implementation of armor weapon SoS effectiveness evaluation system.Finally, an example for armor weapon SoS combat effectiveness evaluation using the improved model and the algorithms for IMADM is carried out, and the evaluation result indicates that the model and algorithms is feasible and reasonable.
