must follow a processing order (σʲ₁, σʲ₂, …, σʲₖ) and each operation (m, j) has a processing time p. The decision variables considered are the time that job j starts on machine m, xₘⱼ; a binary that marks precedence of job i before j on machine m, zₘᵢⱼ; and the total makespan of operation, C, which
