Abstract: Starting with problems that occur in applying cost-effectiveness ratio concept to practical engineering, an in-depth study is conducted on integrated cost-effectiveness characteristics, including its background, definition, connotation, measurement methods, control laws, parameter system, and the workflow of life-cycle management and control, and establishing the new basic concept, methods and technology framework for integrated cost-effectiveness characteristics and its life-cycle management and control. On the basis of the current aircraft type engineering, the study also explores the future applications of the research results.

Key words: military aircraft, integrated cost-effectiveness characteristic, cost-effectiveness index, effectiveness, life cycle cost, cost-effectiveness ratio
