• Metaheuristic approaches to order sequencing on a unidirectional picking line 

      De Villiers, A. P.; Matthews, J.; Visagie, S. E. (Operations Research Society of South Africa (ORSSA), 2013)
      In this paper the sequencing of orders on a unidirectional picking line is considered. The aim of the order sequencing is to minimise the number of cycles travelled by a picker within the picking line to complete all orders. ...
    • On the solution of petrochemical blending problems with classical metaheuristics 

      Venter, Lieschen; Visagie, S. E. (Operations Research Society of South Africa, 2016)
      ENGLISH SUMMARY : In this paper a comparison of classical metaheuristic techniques over different sizes of petrochemical blending problems is presented. Three problems are taken from the literature and used for initial ...
