中文摘要：

轨道客车制造企业需要大量使用板材加工，通过使用优化排样系统可以大大减少材料的使用量，减少企业制造成本。而优化排样系统与PDM、ERP等系统的集成可以保证数据的准确性和一致性。通过优化排样系统的集成环境导人相关数据，修改工艺参数；并使用遗传算法实现对矩形件和不规则件优化排样；对优化排样的结果进行定额计算，最终得到单件定额、下料明细及材料汇总定额等数据，确保了企业对客车板材的最合理使用。

英文摘要：

Using optimal layout system, the usage of material and manufacturing cost are greatly reduced. The accuracy and consistency of data are ensured by optimal layout system integration with PDM, ERP system. Related data was imported from the integration of envi- ronmental by layout optimization system, and process parameters were modified. Using genetic algorithm, the optimal layout for rectangu- lar and irregular parts was realized. The layout optimization results were calculated to get data as single quota, blanking subsidiary, mate- rial summary quota and so on. So, the rational using of vehicle plates for the enterprise was ensured.
