Efficiency of the solution representations for the hybrid flow shop scheduling problem with makespan objective [PDF]

, 2019
In this paper we address the classical hybrid flow shop scheduling problem with makespan objective. As this problem is known to be NP-hard and a very common layout in real-life manufacturing scenarios, many studies have been proposed in the literature to

Computing Idle Times in Fuzzy Flexible Job Shop Scheduling

Algorithms
The flexible job shop scheduling problem is relevant in many different areas. However, the usual deterministic approach sees its usefulness limited, as uncertainty plays a paramount role in real-world processes. Considering processing times in the form of fuzzy numbers is a computationally affordable way to model uncertainty that enhances the ...
