YU WANG et al: PRODUCTION PLANNING MODEL AND ALGORITHM OF DYNAMIC MASS CUSTOMIZATION SYSTEM

Based on the position of a single CODP, the production planning of mass customization is divided into two stages, make-to-stock production before CODP and make-to-order production after CODP. However, in the case of multiple CODPS, production planning of mass customization can be much more complex. This paper presents a dynamic mass customization system, that is, a three-stage production planning model with multiple CODPS. The three stages include push planning, pushpull planning and pull planning. An optimization model for production planning is provided in the aspects of production capacity, inventory constraints and stochastic demand for simulation calculation. The optimization model emphasizes on the analysis of the production planning during the period when push and pull production coexists. Its production volume is considered as the combination of pull production part (customer demands) and push production part (predicted production volume). Moreover, its production planning scheme is the combination of two production schedules. Lastly, the feasibility of the proposed model is tested using the production planning of turbines.
