摘要
研究当需求量巨大且勾随机变量时,单一供应商无法满足供货要求情况下的多供应商采购-库存问题。建立了一个向多个有能力约束的供应商采购的库存模型;由于考虑需求量为随机变量,采用期望值模型对问题进行建模,基于随机模拟的遗传算法对模型进行求解并给出算例来说明模型及算法的有效性,最后给出结论,提示未来的研究方向。
The multi-suppliers purchasing-inventory problem are focused when the demand is tremendous and a single supplier can't meet the demand,in most cases, the demand is stochastic variable. An expectation model placing orders with multi -suppliers with capacity constraint is established, in which the demand is stochastic variable. The genetic algorithm based on stochastic simulation is the effective way to solve stochastic programming. Finally, a simple example, conclusion and potential areas for future research are presented.
