어느 누구도 정확하게 예측할 수 없는 전자상거래 시장에서 한가지 모든 사람들이 공감하는 사실이 있다. 그것은 바로 전자상거래의 부각에 따른 소화물 일관수송시장의 성장이다. 물류의 모든 것이 농축되어 있는 소화물 일관수송업체들이 전자상거래 시대에서 나아가야 할 방향에 관해 살펴보았다

In this study, to investigate the effect of process variables such as reduction in area, semi-die angle and the rectangular ratio to the corner filling which influences the dimensional accuracy of the final product in the drawing of the cluadrangle rod from a round bar, it has been simulated by three dimensional rigid-plastic finite element method. In order to reduce the number of simulation artificial neural network has been introduced. Also, through the experimental investigation, the present results have been implemented on the industrial product. In results, the main process variable is the combination of the semi-die angle in case of the irregular shaped drawing process and reduction in area in the event of regular shaped drawing process, respectively.
