Heijunka mixed model sequencing problem with no buffers and work overload minimization Bautista Valhondo, Joaquín Alfaro Pozo, Rocío Universitat Politècnica de Catalunya.

SIR-OPE - Service and Industrial Robotics - Operation, Production and Enterprise Àrees temàtiques de la UPC::Economia i organització d'empreses::Direcció d'operacions Mixed model sequencing problem Blocking flowshop Heijunka Mixed integer linear programming IBM-CPLEX solver A sequence problem is presented in production lines of mixed fixed-cycle models and time windows with the aim of minimizing production losses in the line and taking into account two types of restrictions: leveling of Heijunka production and suppression of buffers between workstations. The proposed problem is solved by mixed integer linear programming (MILP) using the IBM-CPLEX solver on the set of 23 Nissan-9Eng.I instances. It is concluded that the economic impact due to incremental production losses is significant when the buffers are suppressed in the production line, being of the order of €2600/day.
