Abstract
With wind energy taking up a bigger share of the worldwide electricity production each year and a transition to full sustainability targeted by 2050, effective maintenance planning is essential to minimize costs and downtime. Preventive maintenance is scheduled to reduce the risk of costly corrective maintenance, but unexpected failures and workforce limitations require adjustments to planned schedules. This study addresses the challenge of scheduling multi-component maintenance for wind turbines while accounting for seasonal cost fluctuations and limited personnel availability. When the number of planned maintenance activities exceeds available manpower, one approach is to delay certain planned preventive maintenance tasks to a later period, prioritizing components where postponement has the least expected cost impact. Another strategy is to bring maintenance forward, performing tasks earlier when future workforce shortages are expected. We present heuristic-based strategies that strategically delay or advance maintenance tasks when planned activities exceed workforce. A simulation-based evaluation on a set of 80 identical components highlights how different heuristics perform under varying levels of seasonal cost fluctuations and workforce constraints. Our results show that these heuristics generally outperform naïve scheduling approaches and provide insights into which strategies are most effective under different conditions.
