Abstract: The general quality and design period of a complex system is often difficult to ensure. In order to solve this problem, and based on meta-synthesis method is proposed the function constitution of weapon equipment system and constructed the collectivity optimization design architecture, and its decision support system given. Project design and argumentation, project evaluation, guideline assignment and system simulation are realized. The optimization system could effectively assist the chief stylist to design new type of weapon equipment system, and make it more standardization and more scientific.
