This　paper　combines　the　characteristics　of　windshield　glass　production　process　and　compares　various　intelligent　algorithms.　It　proposes　to　start　from　the　windshield　parallel　multi-machine　manufacturing　process　and　establish　the　simulation　unit　of　windshield　manufacturing　process.　The　method　considers　the　windshield　manufacturing　process.　The　sequence　of　the　process　and　the　factors　affecting　the　tempo　of　each　process　are　transformed　into　genomic　information.　This　paper　establishes　a　simulation　model　of　the　two　-chrome　parallel　multi　-machine　production　line　to　optimize　the　scheduling　of　the　windshield.　This　method　increases　the　production　efficiency　of　the　windshield　manufacturing　process　while　achieving　line　balance　with　minimal　processing　time.　Based　on　the　Plant　Simulation　simulation　platform,　the　effectiveness　of　the　proposed　method　is　verified　by　optimizing　the　production　line　of　parallel　multi-machine.
