We address the problem of scheduling jobs with non-identical sizes and distinct processing times on a single batch-processing machine, aiming at minimizing makespan. The extensive literature this NP-hard mostly focuses heuristics. Using an arc-flow based optimization approach, we construct novel formulation that represents it as determining flows in graphs. size increases machine capacity numbe...

This paper considers a single-machine scheduling problem with sequence-dependent setup times and energy-generation storage systems. Each job requires to be processed on the machine, both processing of require job-dependent amounts energy. The energy consumed by machine can bought from an Electric Power Company (EPC) or generated own Distributed Energy Resource (DER), such as solar photovoltaic ...

We study individual pulses of Vela (PSR\ B0833-45\,/\,J0835-4510) from daily observations over three hours (around 120,000 per observation), performed simultaneously with the two radio telescopes at Argentine Institute Radioastronomy. select 4 days in January-March 2021 and their statistical properties machine learning techniques. first use density based DBSCAN clustering techniques, associatin...
