Abstract: To solve the problem of resource optimization and scheduling for the mixed-model manufacturing system considering handling time,the operation organization modes and parts'sequencing were researched deeply.The equipment shutdown frequency,parts'handling times,handling equipment amount and equilibrium degree of handling times were taken as the first,second,third and forth optimization objectives and the makespan was taken as the constraint,a multi-objective decision-making model was established to select the appropriate operation organization mode and to determine the optimal scheduling scheme.The different targets and restraint that could be used for solving the model were researched.The processing time models were established and the optimization model of handling time was designed.Meanwhile,a detailed algorithm procedure for the frequency of equipment shutdown was presented.A software system of the mixed-model manufacturing system considering handling time was developed.Besides,a global optimization algorithm for the amount of handling equipment was designed.The effectiveness of the proposed method was validated by the analysis and solution of enterprise order data.
