چکیده
Based on credibility theory and two-stage fuzzy optimization method, this paper presents a type of multi-product multi-period (MPMP) production planning model. Since the proposed production planning problem includes fuzzy variable coefficients with an infinite support, it is infinite-dimensional optimization problem. The approximation of the production planning problem is discussed, and the convergence of the objective value (optimal value) of the original production planning problem to the objective value (optimal value) of the approximating production planning problem is also considered. Finally, the approximation method is embedded into a genetic algorithm (GA) to produce an approximation-based GA for solving the proposed production planning problem, and a numerical example is provided to show the feasibility of the algorithm.

متن کاملEstimating Capacity Utilization in Two-Stage Production Systems: A Data Envelopment Analysis Approach
The current study investigates performance in two-stage production systems through the measurement of capacity utilization (CU). In short-run, the degree of capacity utilization depends on the ability of decision making units to utilize fixed production factors. To develop this indicator in two-stage production processes, a modified SBM network DEA model is proposed. A numerical example is also...
