为兼顾供应链系统的弹性和运作成本,提出三前馈自动渠道的、基于库存和定购的生产控制系统(Triple feed-forward automatic pipeline,inventory and order-based production control system,TFF-APIOBPCS)。在自动渠道的、基于库存和定购的生产控制系统模型中,增加一阶微分前馈环节,以部分抵消需求波动对库存的影响。在零稳态误差情况下针对生产控制系统的不同极点分布,分析一阶微分前馈环节的参数与供应链弹性的关系。综合考虑库存成本及生产调节成本,构造供应链系统的运作成本模型。通过阶跃需求、随机需求下的供应链系统仿真,评估一阶前馈环节参数对供应链弹性及运作成本的影响,验证三前馈自动渠道的、基于库存和定购的生产控制系统的有效性。结果表明,针对不同波动程度的需求,合理设置一阶微分前馈环节的参数,可以获得弹性与运作成本的良好均衡。
In order to trade off between supply chain resilience and operational cost, a sort of triple feed-forward automatic pipeline, inventory and order-based production control system(TFF-APIOBPCS) is presented. A first order differential feedforward unit, introduced to production control model APIOBPCS, enables the model to mitigate the impact of fluctuations in demand on actual inventory. Aiming at different pole distribution of the production control system, analysis of the relationship between the parameters of first order differential feedforward and resilience are conducted under zero steady-state error. Supply chain operational cost model is constructed by comprehensive consideration of inventory cost and production regulation cost. Supply chain system simulations with a unit step signal and a stochastic signal as the customer demand evaluate the effect of the first order differential feedforward parameters on supply chain resilience and operational cost, and reveal the validity of TFF-APIOBPCS. The results show that, for different degree of volatility of demand, setting the parameters of first order differential feedforward unit reasonably, can obtain better equilibrium of elasticity and operation cost.
