摘　　要：文章以不可靠生产系统为对象,研究了生产过程劣化、设备随机故障及第Ⅱ类检查错误共同影响下的生产计划和检查策略的联合优化问题。根据问题描述,建立了含生产过程劣化、设备随机故障及第Ⅱ类检查错误的定期检查的单周期经济生产批量模型,求得使单位时间内总费用期望最低的经济生产批量和最优检查策略。通过算例分析表明:随着第Ⅱ类检查错误率的上升,单位时间内总费用期望增加,经济生产批量稳定,最优检查次数增加。For the unreliable production system with deterio- rating process and random machine failure and type Ⅱ in- spection error, the problem of simultaneous determination of production schedule and inspection policy is researched. Based on a given problem, an economic manufacturing quantity （EMQ） model with equal-spaced inspection in the context of deteriorating production process and random machine failure and typeⅡ inspection error is established, which rams to dis- cover the economic manufacturing quantity （EMQ） and opti- mal inspection schedules, minimizing the expected average to- tal cost per unit time. Finally, the effective of this model is verified by a numerical example.
