COMPLEX PRODUCT FAMILIES MAINTAINABILITY ASSESSMENT AT DESIGN STAGE

摘要

The functionalities and performance expected to modern products are increasing continuously. They generate very important conceptual, technological and functional complexities and require designers to study the behaviour of the products at the early design stage. Moreover, in order to model complex product families and extract from their instances the ones that fulfil the requirements, constraints and specifications, it is necessary to be able to instantiate the meta-model and evaluate the resulting instance (product). This instance is then either validated or improved or abandoned according to the satisfaction of the requirements. It is also possible to switch to another instance and to restart the process. In this paper, we propose an improvement of the maintainability indicators such as the disassembly time and the replacement time of failed components and a behavioural performance engineering algorithm for complex product families at the early design stage. This methodology allows us to extract from complex product families, the ones that satisfy the requirements and constraints of the customers and designers.
