Minimizing total weighted tardiness for the single machine scheduling problem with dependent setup time and precedence constraints

This paper tackles the single machine scheduling problem with dependent setup time and precedence constraints.The primary objective of this paper is minimization of total weighted tardiness.Since the complexity of the resulted problem is NP-hard we use metaheuristics method to solve the resulted model.The proposed model of this paper uses genetic algorithm to solve the problem in reasonable amount of time.Because of high sensitivity of GA to its initial values of parameters, a Taguchi approach is presented to calibrate its parameters.Computational experiments validate the effectiveness and capability of proposed method.
