Abstract

Long-term manufacturing would bring performance degradation of key equipment in automated production lines (APLs), leading to operating unbalance and inefficiency. The existing maintenance strategies can generate maintenance schemes, but they generally ignore performance degradation that can further influence the production process. To efficiently generate maintenance schemes with maximized availability and minimized cost, an availability-oriented maintenance strategy considering performance degradation is proposed based on a synchronized hybrid optimization algorithm (SHEA) in this study. Firstly, the performance degradation of key equipment in APLs is analyzed based on the Weibull distribution, and the availability of the equipment is analyzed considering performance degradation. Secondly, a maintenance model for the key equipment in APLs is established, and a SHEA based on multi-objective particle swarm optimization (MOPSO) and squirrel search algorithm (SSA) is proposed to optimize the maintenance model with higher efficiency. Finally, the effectiveness and superiority of the proposed method are verified by citing a practical APL of the engine cylinder head as an example in the case study.
