Methods for engineering change propagation analysis

Abstract

The aim of the methods described in this paper are to simulate and analyse the
\npropagation of changes in an engineering product,process and/or organisation,so
\nthat time,cost,and resources can be allocated according to the impact of the
\nchange.The paper presents advanced concepts for capturing dependencies between
\nsuch viewpoints of the overall engineering system. In the proposed
\napproach,simple Boolean dependencies and dependency strengths can be described
\nalong with types and levels of change. The objective is to define dependencies
\nmore completely by taking into account that the number and the strength of these
\nmay vary throughout the product life cycle. Case studies from the aerospace
\nindustry are being used to test the advantages and limitations of the proposed
\nengineering change propagation analysis methods
