طراحی یک مدل ریاضی جدید برای مسئله تشکیل سلول پویا برمبنای تعداد و متوسط طول حرکات درون و بین سلولی

  In this paper a new nonlinear integer programming model is presented for dynamic cell formation problem (DCF) in cellular manufacturing system (CMS). idea “higher material flow in shorter distance” for formation of cells is introduced. Since the linearized model is NP-hard, a novel approach called local search embeded branch and cut (LSEBC) is introduced. Computational results show the efficiency of the LSEBC in comparison with standard comparable methods.
