Problems solved by technology
[0003] 1. In the modeling process of existing technical solutions, most of them lack consideration of discrete events such as failure of production line equipment or the need for preventive maintenance, so most of the obtained models lack the brittleness assessment of the production line
[0004] 2. In the face of equipment failure or preventive maintenance, most of the existing technologies lack mathematical quantification of the brittleness of the production line, so it is difficult to analyze and evaluate the failure of the production line and make flexible control decisions

The invention discloses a method for measuring a brittle time window of an assembly production line and an elastic control system, and relates to the technical field of industrial automation. A method for measuring the brittle time window of the assembly line, which obtains the state equation of the assembly line through the elastic control system, and obtains the brittle time window of the machine under each potential disturbance event according to the state equation of the assembly line, that is, calculates the occurrence time of the disturbance event The time interval between the assembly line and the moment when the assembly line causes permanent production loss, and then by judging whether the duration of the disturbance event is within the brittleness time window, the mathematical quantification of the brittleness of the assembly line is realized, and the brittleness of the assembly line is evaluated. And then realize the reasonable maintenance decision for the assembly line, which is of great significance to the actual maintenance, energy saving and production change of the assembly line.
Description
technical field [0001] The invention relates to the technical field of industrial automation, in particular to a method for measuring a brittle time window of an assembly line and an elastic control system. Background technique [0002] Existing technologies focus on the performance evaluation under normal working conditions of the production line, which is close to the static design, while the dynamic performance analysis of the production system has received less attention. In addition, the existing technology usually measures the production line through performance indicators such as utilization rate and total production volume from a statistical point of view, and mostly ignores the measurement of production line failures and control decisions after failures. Therefore, the biggest shortcoming of prior art is: [0003] 1. In the modeling process of existing technical solutions, most of them lack consideration of discrete events such as failure of production line equipme...
