资金链是企业的生命线,研究资金周转周期对供应链整体绩效的影响,以资金周期为控制变量,以Petrinet建立三阶段线性供应链模型,设各厂商有安全库存水平,以供应商、制造商账户余额和供应链总产出为指标,数值仿真表明缩短资金周转周期对供应链总产出和账户余额有促进作用且边际递减。 The capital chain is the lifeline of the enterprise, and studies the impact of the capital turnover cycle on the overall performance of the supply chain. Taking the capital cycle as the control variable, Petrinet establishes a three-stage linear supply chain model and sets the safety stock levels of each manufacturer to suppliers and manufacturers Account balance and total supply chain output as indicators, the numerical simulation shows that shortening the capital turnover cycle can promote the supply chain total output and account balance with diminishing margins.
