Job Shop Web

Job Shop Web is an application for didactic purposes that allows solving the job shop problem with makespan minimization using four models of mixed integer linear programming:

• Disjunctive model (Manne);
• Disjunctive model (Liao);
• Time-indexed model;
• Rank-based model.

The models are based on the works of Manne (1960), Liao e You (1992), Kondili et al. (1988), and Wagner (1959), respectively. Their computational implementation was facilitated thanks to the works of Ku e Beck (2016) and Aguiar Júnior (2021) and to Professor Cassiano Tavares' classes.
