A multi-objective multi-micro-swarm leadership hierarchy-based optimizer for uncertain flexible job shop scheduling problem with job precedence constraints

作者：

Highlights：

• Interval grey processing time and trimmed triangular fuzzy due time are modeled.

• Delay degree of grey end time over fuzzy due time is assessed by tardiness index.

• Sequential operation and hierarchical job precedence constraints are considered.

• Two-vector encoding and heuristic active grey decoding schemes are designed.

• A novel multi-micro-swarm leadership hierarchy-based optimizer is developed.
