The evaluation of the equipment system contribution can provide effective theoretical support for equipment development demonstration, combat test development and operational use guarantee. This paper mainly analyzes the conceptual connotation of the contribution degree of weapon equipment system, summarizes the existing methods of equipment system evaluation, constructs an evaluation index system of weapon equipment system contribution, and gives the contribution of weapon equipment system based on envelope analysis method. Degree evaluation models and steps, case evaluation and verification analysis are given, respecitvely. The research work has verified the feasibility and effectiveness of the mathematical model, as well as provides strong theoretical support for decision makers to make choice of equipment.
