【摘要】 本文综合考虑生产维护决策对生产绩效的影响,以综合生产收益最大化为目标研究了生产预防维护决策问题。首先提出了以故障构件重要度系数之和来指示设备状态的方法,并使用复合泊松过程模拟了设备状态的持续劣化过程,然后在产品需求随机、产品不合格率随设备状态劣化而递增的情况下,分析了企业的预防维修成本、生产成本、质量成本、库存成本、缺货成本,得到总的综合生产总收益,从而构建企业单位时间毛利润最大化的生产维护决策模型,并给出了较为详细的求解方法,最后通过算例验证了本文理论的有效性性和实用性且对某些参数进行了敏感度分析。研究结果表明,由本模型得到的基于生产收益最大化的生产预防维护决策不仅能有效降低企业不合格品的产出而且能大大提高其盈利水平,此外企业也应注重关键零部件的修复与替换,及时对设备进行更新换代。更多还原

【Abstract】 In this paper,by considering the impact of production maintenance on the production performance,the preventive production maintenance decision for compound Poison process manufacturing system is studied based on the maximizing of comprehensive production performance.Firstly,the method that equipment condition is indicated by the sum of importance coefficients of failure component is proposed,and compound Poisson process is used to simulate continue degeneration process of equipment.Then,preventive maintenance cost,production cost,quality cost,inventory cost,shortage cost and total revenue are analyzed when product demand is random and product fraction defective increases with the degeneration of equipment.In addition,the profit maximization model is constructed and a solution method is provided as well.Finally,the method proposed in this paper is verified through a numerical case and the sensitivity of some parameters is analyzed.The result shows that the preventive production maintenance decision obtained by the model can not only reduce defect products but also increase it profitability greatly.Moreover,enterprises should care about the repair and replacement of key components of equipment and replace equipment in time.更多还原
