Constraint Programming Approach to Steelmaking-making Process Scheduling
TLDR
This paper presents a constraint programming (CP) approach to optimal steelmaking process scheduling with constraints of processing time, limited waiting time between adjacent stages, serial batching, sequence independent setup time, release/due time, and with the objective of minimizing maximal total waitingTime between adjacent charges in the same casts.

A co-evolutionary genetic algorithm for the two-machine flow shop group scheduling problem with job-related blocking and transportation times
TLDR
We propose a co-evolutionary genetic algorithm to solve a two-machine flow shop group scheduling problem with job-related blocking and transportation times, which is derived from the realistic pipe-making process of steel pipe products in the modern steel manufacturing industry. Expand
