A Study for Selecting the Optimal Model among Ten Models of Crushing Machine with Various Constraints Related to Road Repairing

도로공사에 관련된 많은 제약조건을 갖는 열개의 파쇄장비 모델들 중 최적 모델 선정에 관한 연구

It is not difficult to see the road repairing. There are many and various machines that can crush road surface. The efficiency and power of the machine depend on crushing head-shape, crushing interval, crushing load, crushing stress, machine's dropping height and roller's kind. The objective of this study is to select the optimal model among ten models of crushing machine with constraints such as crushing depth, variation, and crushed particle size. The data for this study are chosen from the site of construction in Kangnung during three months ($2004.\;6.\;1\;\sim\;2004.\;8.\;31$). The provided methodology in this paper will be fruitful not only for the selection of crushing machine but also for the aspects of construction period, cost, work efficacy according to the condition from the various sites of construction.
