Some automation allocation problems are carried by digitizing the human-system interface in main control rooms (MCRs).To improve human performance, the purpose of this study is to determine the effect of automation on mental workload and operation performance in the advanced MCRs.The study provides design implementation guidelines for three types of computerized procedures;they are (a) paper-based procedure;(b) electronic procedure;(c) computer-based procedure.Experimental results reveals that the automation allocation type with higher ratio automatic mode result in the superior primary task p...
