this study emphasizes the cost estimation
approach for plastic injection products and molds. It is expected designers and R&D specialists can consider
the competitiveness of product cost in the early stage of product design to reduce product development
time and cost resulting from repetitive modification. Therefore, the proposed cost estimation
approach combines factor analysis (FA), particle swarm optimization (PSO) and artificial neural network
with two back-propagation networks, called FAPSO-TBP. In addition, another artificial neural network
estimation approach with a single back-propagation network, called FAPSO-SBP, is also established. To
verify the proposed FAPSO-TBP approach, comparisons with the FAPSO-SBP and general back-propagation
artificial neural network (GBP) are made. The computational results show the proposed FAPSOTBP
approach is very competitive for the product and mold cost estimation problems of plastic injection
molding.
