Application of Quality Function Deployment to the design and production of Persian Hand-made carpets.
Persian Carpet is one of the most important exports of Iran, and is a symbol of
Iranian art and culture. In recent years, there has been competitive market in
hand-made carpet, which has made the producers improve the quality of their
products according to customer demands.
QFD is a technique, that can be used to improve the quality of the hand-made
carpets. It could match the product specifications and the customer expectations.
In this paper, several approaches are proposed to improve the hand-made carpet
quality using QFD technique. Since QFD has less been used in the manufacturing of
products with artistic characteristics, the proposed approaches can be interesting
to the QFD audience.
After a brief history of the Persian carpet, its position in Iran's economy is
highlighted. Its world market, customer variety, and competitors are introduced.
The QFD process is divided into five stages. These stages include the construction
of the matrices: the evaluation of customer requirements importance, the house of
quality, part planning, process planning, production/ operation planning.
In this case study, the evaluation of the customer requirement matrix is introduced
to prepare an appropriate input to the house of quality matrix.The results are
discussed and several conclusions are made based on the findings. Several
suggestions are presented to improve the quality of hand-made carpets.
