不完美生产品质的模糊经济生产批量模型

Optimization of fuzzy production inventory model with imperfect production quality

针对实际生产过程中出现不良品进行返修的情况,提出两种不良品可修复的模糊经济生产库存模型:一种是具有模糊成本和明确的生产数量,另一种是具有模糊成本和模糊生产数量。使用功能原则和梯级平均综合表示法来求解最优模糊经济生产批量,并将模糊产品存货总成本函数修正为循环周期内的库存总成本函数,最后采用数值算例来检验模型的有效性。

Introduces a fuzzy economic production quantity model with defective products that can be repaired. In this model, consider a fuzzy opportunity cost,trapezoidal fuzzy costs and quantities into the traditional production inventory model. Use function principle and graded mean integration representation method to find optimal economic production quantity of the fuzzy production inventory model. Finally, one numerical example is also given to illustrate the results.
