Abstract:

Changes in automotive markets and technologies amplify the issue of fulfilling requirements for all customers within a single vehicle concept. An increasing development of regional markets demands vehicle concepts, which fit the customer’s wishes and satisfy the environmental conditions. In this paper, a requirement-driven approach is proposed. The approach introduced deals with the issue of relations between the customer’s requirements and the technical characteristics and properties, especially in the early stages of product design. Here, the vehicle requirements are determined and related to the vehicle environment. And together with experts in each vehicle field the relationships between components, among requirements, and between components and requirements are traced and analyzed. With this approach, vehicle concepts can be compared based on the level of satisfaction that their different selected components achieved in specific markets.
The analysis is achieved by modeling all these relationships in the Systems Modeling Language (SysML), which is common practice in system and software engineering where multiple systems need to be described
