Abstract: In recent years, with the enforcement of people's environmental protection awareness and the improvement of environmental protection regulation,more and more focuses and importance are attached on reverse logistics. End-of-life items disposal facilities' location problem (EIDFI_P) is a key research direction in reverse logistics research. Whether the EIDFLP can be effectively solved is directly related to the degree of improvement on people's daily life. In this paper,for solving a multi-objective EIDFLP from literature,the multi-objective EIDFLP was transformed into a single-objective problem and then a novel harmony search algorithm (HSA) was proposed. hhrough the computational results,we found that the best result of HSA is the same as that in literature, the computational time is much less than that of algorithm in literature and there arc some errors in a reported solution.
