“…Therefore, identifying bottlenecks is the key to accelerating the optimisation process management, which aims to improve work quality and efficiency [2]. For example, identifying production bottlenecks in the automotive assembly process can provide manufacturers with essential decision input [3], identifying bottleneck manufacturing resources in the intelligent workshop can provide a decision-making basis for subsequent production management [4], and identifying bottleneck machines can reduce the influence on the maximum completion time [5].…”
