英文摘要： Complexity of product design and development is shown mainly as coupling complexity. Iteration and coupling are the main characteristics of complex product design and development. The coupling complexity of product design and development is a frontier interdisciplinary field between engineering design science and complexity science, which is in the constant research and exploration. This project, from the perspective of the complexity of product coupling, will focus on the theory and method of decoupling of complex product design and development to implement multi-faceted research, which mainly includes establishing decoupling collection solution model based on resource constraints, coupling collection mixed iteration model based on statistical method, and designing iteration model based on feedback control theory under uncertain conditions by means of integrating theories and methods of axiomatic design, genetic algorithm and control theory. Meanwhile taking the important mechanical and electrical equipment, gantry crane, in project construction as the object of engineering application, the applied research will be carried on to solve the coupled problem in luffing system design. The achievements of the study can not only contribute to promote the interdisciplinary integrating research of a variety of advanced theories and methods, reveal the inherent law of design and development of complex product, expand the application fields of the existing theories and methods, enrich and develop decoupling theory and technology of coupling design of complex mechanical and electrical product, but also provide scientific guidance for the design and development of complex mechanical and electrical product in practical engineering.
