Abstract :
This study assesses the predictability of neural networks to estimate the cost of thin-film transistor liquid-crystal display (TFT-LCD) equipment. Newly completed equipment-development projects are provided by departments in a Taiwanese high-tech company. Cross-fold validation method is applied to measure model performance and reliability. Analytical results show the generalized regression neural net outperforms multi-layer feed-forward net when used for cost estimation during conceptual stages. Project managers can benefit from applying the approach to establish functional relationships for the high-tech TFT-LCD equipment manufacturing industry.
