Abstract: To research the effective method for improving the productive efficiency with line-cell conversion,on the premise of not adding the labor hours,the productive efficiency was improved by line-cell conversion.To decrease the complexity of line-cell conversion multi-objective model,a single-objective model with the constraint of labor hours was presented by considering the minimized Total Through Put Time(TTPT).Line-cell conversion was a NP-hard problem,thus an algorithm based on Variable Neighborhood Search(VNS)was proposed.Extensive numerical experiments were performed to evaluate the performance of the proposed VNS and to investigate how to do line-cell conversion can reduce efficiently TTPT without increasing TLH.

Key words: line-cell conversion, increasing productivity, total throughput time, total labor hours, variable neighborhood search
