Abstract

As a typical complex system, the requirements of stakeholders such as market, customers and operating conditions have an important impact on the design EMUs. At present, the EMU manufacturers still adopt the idea of traditional system engineering to decompose the requirements, resulting in the lack of traceable links between requirements and design, which seriously prolongs the product development cycle and increases the development cost. Under this background, this paper introduces the idea of model-based systems engineering (MBSE) into the EMU requirements management. The method is vertically divided into four aspects: the L1 layer is customer requirements, the L2 layer is product requirements, the L3 layer is system requirements, and the L4 layer is component requirements; the horizontal activities are divided into five steps: requirements capture, requirements analysis, requirements confirmation, requirements allocation, and requirements verification. It is applied to the requirements management of EMUs air conditioning system, and the results show that the application of MBSE to EMUs requirements management can establish the traceability relationship between requirements and design, ensure the accuracy of requirements, improve the efficiency of requirements management, and realize the transformation of EMU requirements from “document based” to “model-based”.
