Dynamic mission reliability modeling for a manufacturing system with multiple production lines

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.
