Abstract

In this paper a Variable Neighborhood Descent (VND) approach, is developed to solve the Single Machine Total Weighted Tardiness Problem (SMTWTP). New strategy was proposed to select iteratively the accurate neighborhood. Our approach was compared to VND state-of-the-art approaches. Statistical tests were also applied on the empirical results, to show that the DR_VND outperforms the proposed approaches for 72 % of instances for the SMTWTP. The proposed approach was applied on a real case.
