An Adaptive Maintenance Model Oriented to Process Environment of the Manufacturing Systems

Abstract EN

We explored an adaptive maintenance model of the process environment to diagnose progressive faults in manufacturing systems.

Progressive faults are usually caused by deterioration of the operating environment or aging and show stochastic properties.

Many researchers have reported how to detect faults on the machine body in manufacturing systems.

However, little research has been conducted on the process environment which causes progressive faults.

To tackle this problem, we explored an adaptive maintenance model to detect progressive faults and repair the process environment on the E-repair location.

When a difference of the environmental factor state is detected, it will combine the transcription factor and the state enzyme to locate fault source.

Then the comprehensive maintenance program is derived to repair the operating environment while eliminating progressive faults.

For the purpose of validation, this model was implemented on the process environment of the air separation plant.

And the simulation experiments validated the feasibility and effectiveness of this method.
