ABSTRACT


The purpose of this study was to assess the less-tangible benefits of an ergonomics project performed in a 300-mm wafer fabrication in Taiwan. The studied project was aimed at reducing the risk factors of musculoskeletal disorders (MSDs) faced by the wafer-handling workers. Firstly, the MSDs checklist was used to identify risk factors for the workers. The ergonomic intervention was then conducted. Subsequently, the willingness-to-pay (WTP) survey of the contingent valuation method was performed to quantify less-tangible benefits. The responded WTP results were analyzed to estimate the return on investment of this project, which was 43.6% and large enough to conclude that this project was cost-effectiveness. The marked decreases in the risk-factor found rate and the self-reported MSD rate in the post-intervention period proved that the intervention was effective in reducing the MSD problems. This paper is shown to be a good example to justify the worth of an ergonomics project.


Keywords: Cost effectiveness; musculoskeletal disorders; less-tangible benefit.
