    Development of an optimal production allocation model for multistage multilocation multi period system
    (Department of Industrial and Production Engineering, BUET, 1999-08) Mahbubur Rahman, Md.; Anwarul Haque, Dr. A. F.M.
    Multistage multilocation multiperiod production systems arc very common m manufacturing and business arena, Production allocation for multistage mUltilocation mltiperiod system is of great importance to the academi(;s, researchers and managers. The task of production allocation for multistage system is a highly complex job because of the requirement of incorporating various aspects of overall manufactming and business scenario and inventory oricnted factors. This task bewmes uphill especially, for assembling oriented enterprises. To get a realistic solution of production allocation, the search for effective quantitative techniques is an essential one. Mathematical modelling is an efficient approach to these cases. In this research work attempt has been made to develop mathematical models relating to various situations, -starting from very simple cases to the complex assembling oriented systems. All the developed models were tested with data and .found to' provide optimum solutions. 'Inc linear programming methodology was employed for solving the problems assuming the associated costs linear. ,jj • Beside the analytical ability and conceptual maturity of the designer, the success of this modelling approach sterns from its nature of incorporating updated and correct data. Models relied highly on modem information technology. The presence of management information system (MIS) in the enterprise was felt to be very essential.
