Product-Process MBSE and Dysfunctional Analysis Approach Applied to a Production Line

摘要

The integration of new technologies and the increasing customer requirements in manufactured products requires more complex and automated production lines. Manufacturing processes are usually designed for a specific range of products. Thus, it is important to consider the dysfunctions of the product ans process conjointly. The aim of this paper is to propose a Model-Based Systems Engineering product-process approach for the dysfunctional analysis. This methodology consists in two phases: a functional analysis using SysML language for the system behavior and structure modeling, and a dysfunctional analysis using a combination of FMECA and FTA considering external intervention of the humans. This approach highlights the relations between the process and product failures and the importance of MBSE in the product-process dysfunctional analysis.
