This paper presents a simulation and comparison analysis conducted to investigate the due-date\udassignment methods through various scheduling rules. The due date assignment methods investigated are\udflow time due date (FTDD) and total work content (TWK) method. Three scheduling rules are integrated in\udthe simulation for scheduling of jobs on machines. The performance of the study is evaluated based on the\udconfiguration system of Hibret manufacturing and machine building Industry, subsidiary company of\udMetals and Engineering Corporation were thoroughly considered. The performance of the system is\udevaluated based on maximum tardiness, number of tardy jobs and total weighted tardiness. Simulation\udexperiments are carried in different scenarios through combining due-date assignment methods and\udscheduling rules. A two factor Analysis of variance of the experiment result is performed to identify the\udeffect of due-date assignment methods and scheduling rules on the performance of the job shop system. The\udleast significant difference (LSD) method was used for performing comparisons in order to determine\udwhich means differ from the other. The finding of the study reveals that FTDD methods gives less mean\udvalue compared to TWK when evaluated by the three scheduling rules
