Abstract: Aiming at the problem of the complex associations between operators and equipments,an easy to solve linear integral programming model for mold machining process of Mold and Die (MD) enterprise based on dual resource constraints was developed,and the optimal solution was obtained by means of Lingo.To validate the effectiveness of this mathematical model,a simulation program was established according to the typical operation mode of MD enterprises.The simulation results showed that due to the limitation of real production system such as arrival time,scheduling strategies and buffer capacity,the calculated numbers of equipments and operators from proposed model were less than the practical demands.However,the approximate degree of proposed mathematical model was acceptable by considering the simplicity and convenience of the solution approach.
