|Abstract: ||The prediction and capturing of defects in low-volume assembly of electronics is
a technical challenge that is a prerequisite for design for manufacturing (DfM) and business
process improvement (BPI) to increase first-time yields and reduce production costs. Failures
at the component-level (component defects) and system-level (such as defects in design and
manufacturing) have not been incorporated in combined prediction models. BPI efforts should
have predictive capability while supporting flexible production and changes in business models.
This research was aimed at the integration of enterprise modelling (EM) and failure models (FM)
to support business decision making by predicting system-level defects. An enhanced business
modelling approach which provides a set of accessible failure models at a given business process
level is presented in this article. This model-driven approach allows the evaluation of product
and process performance and hence feedback to design and manufacturing activities hence
improving first-time yield and product quality. A case in low-volume, high-complexity electronics
assembly industry shows how the approach leverages standard modelling techniques
and facilitates the understanding of the causes of poor manufacturing performance using a
set of surface mount technology (SMT) process failure models. A prototype application tool
was developed and tested in a collaborator site to evaluate the integration of business process
models with the execution entities, such as software tools, business database, and simulation
engines. The proposed concept was tested for the defect data collection and prediction in the
described case study.|
