【摘要】 面向客户订单的多品种、小批量的生产模式，正在成为墙纸行业的主导生产方式。因此，合理而有效的生产调度及统计系统对于墙纸行业具有重要的意义。本文以研究墙纸企业按订单生产的特点为基础，采用全局搜索能力很强的遗传算法，开发了一个具有实际应用价值的生产调度及统计系统。本文研究的主要内容包括： 1) 分析了墙纸行业的生产模式：属于面向订单生产的半流程制造业。并指出了其生产调度的特点：生产工序是连续且有先后顺序的，但工序之间又可以间断，而且可以到不同的机器上完成该工序的生产，生产调度的主要目标是尽可能缩短生产时间，提高生产设备的利用率。 2) 对生产调度问题的研究现状和研究方法做了综述和整理，深入探讨了遗传算法的基本原理和基本流程，并结合墙纸行业的生产模式和生产特点，指出其属于混合flow shop问题，采用基于置换编码的遗传算法，并以最小生产时间作为目标函数，较好的解决了由人工调度带来的墙纸生产设备使用效率偏低的问题，提高了生产效率。 根据以上研究，开发了一套生产调度和统计系统，作为广东某墙纸厂ERP系统生产模块的有机组成部分，并得到了比较好的应用效果。更多还原

【Abstract】 Multi-varieties and small batch production is becoming the dominate mode for the wall-paper industry. So, it is very important for the wall-paper industry to establish effective production scheduling and statistical system. On the base of studying the characteristics of make-to-order wall-paper industry, this paper utilizes the whole situation search for very capable genetic algorithm to develop a production scheduling and statistical system. The thesis includes the following main content:1) The production mode of the wall-paper industry based on make-to-order are studied, then the characteristics of wall-paper industry’s production scheduling are pointed out: there is priority order in succession in the work procedure, but can be halted again between the procedure, And can reach the production finishing this work procedure on different machine, The main target of production scheduling is to make full use of production equipments.2) The research status and methods are summarized. The fundamentals and basic flow of genetic algorithm are discussed in detail. Associated with the production mode and characteristics of wall-paper industry, its production scheduling belongs to the hybrid flow shop’s problem. Applied based-on permutation coding genetic algorithm and used minimal production time as target function, it is solved the problem of low efficiency of wall-paper production equipments’ utility that is caused by manpower scheduling and improved the production efficiency.According to the above study, a production scheduling and statistic system is developed, which is the organic part of the ERP system of wall-paper factory in Guangdong Province , And the application results show that the system is efficiency.更多还原
