Abstract

Around the "fault diagnosis" to analyze the manufacturing system reliability at the device performance level, it is increasingly unable to meet the requirements of predictive production. To achieve refined and integrated manufacturing process control and optimization, a dynamic mission reliability modeling method for manufacturing systems with multiple production lines is proposed in this paper. First, based on the operating mechanism of the manufacturing system and its dynamic composition, the connection of manufacturing system mission reliability covering the equipment, material, and task is proposed. Second, the mapping decomposition of task load in the manufacturing network model is analyzed and quantitative modeling is performed. Third, focusing on manufacturing mode of multiple production lines and considering the inherent multi-state characteristics of manufacturing systems, a mission reliability model of manufacturing system which integrated task planning is established. Finally, a case study is conducted to validate the proposed model.

多生产线制造系统的动态任务可靠性建模

围绕“故障诊断”在设备性能层面分析制造系统的可靠性，越来越不能满足预见性生产的要求。为实现精细化、集成化的制造过程控制与优化，提出了一种多生产线制造系统的动态任务可靠性建模方法。首先，基于制造系统的运行机理及其动态构成，提出了制造系统任务可靠性涵盖设备、材料和任务的关联;其次，分析了制造网络模型中任务负荷的映射分解，并进行了定量建模。第三，针对多生产线制造模式，考虑制造系统固有的多状态特性，建立了集成任务规划的制造系统任务可靠性模型。最后，通过实例分析验证了该模型的有效性。
