parcel delivery is a complex logistic service, as it serves many small or medium-sized customers who may send or receive parcels. modeling such delivery system needs to integrate two different research areas of hub location and vehicle routing. as it totally depends on the network and the linkage of the nodes, in this paper, some door-to-door service providers are taken into account to provide ...

in this paper, we considered solving approaches to flexible job shop problems. makespan is not a good evaluation criterion with overlapping in operations assumption. accordingly, in addition to makespan, we used total machine work loading time and critical machine work loading time as evaluation criteria. as overlapping in operations is a practical assumption in chemical, petrochemical, and gla...

Abstract—Artificial intelligence (AI) has rapidly advanced, leading to the development of AI systems that can generate solutions tailored specific model architectures. This study focuses on comparing accuracy and efficacy AI-generated those created by human experts during construction. While human-generated are generally expected be more accurate due a better understanding underlying physics, m...
