ESTIMATING THE PRODUCTION TIMES IN PCB ASSEMBLY

摘要

Several control problems of PCB assembly industry involve the estimation of the component placement times for various dierent placement robots. A standard approach, widely used in scientic literature, is to let the time to be a linear function of the number of components. In this paper, we demon-strate that a more realistic model should include additional parameters (e.g., the number of dierent component types and the board size). Linear mul-tiregression indicates that the coeÆcient of determination for the improved model is over 90 percent.
