摘要
由于市场的不确定性,延期支付货款和存货质押融资中存在诸多不确定因素,使得资金需求企业难以做出有效的选择。针对此问题,从资金需求企业利润最大化的角度出发,首先分别给出了延期支付和存货质押两种业务下的企业利润模型,进而基于D-S理论建立了两种业务的决策模型。该模型以存货质押和延期支付业务下企业利润差额为目标函数,根据证据推理,以信任函数和似然函数构造出利润差额的上下界概率分布,并据此给出两种业务的决策依据。算例分析表明,对资金需求企业来说,存货质押融资业务并不一定优于延期支付,在特定的市场环境下,需要利用本文提出的模型进行定量计算,从而做出最优的选择。
Because of uncertainties in market , there are several uncertain factors in inventory impawn financing and delayed payments , such as cash discount rate , inventory impawn financing rate , and lost sale penalty cost . These uncertain factors have important impacts on enterprise profits .As a consequence , it is difficult for an enterprise to decide which business to select .To solve this problem , enterprise profit models under the methods of inventory impawn financing and delayed payments are derived first .Then the decision model of business selec-tion is proposed based on evidence theory .In this model, profit difference between inventory impawn financing and delayed payments is taken as the object function .Based on evidence reasoning , lower and upper probability distributions of profit difference are constructed with belief and plausibility functions , with which the decision-making basis for the two businesses is proposed .The simulation results show that , inventory impawn financing is not always better than delayed payments to an enterprise demanding for funds .In a special market , best selection within these two businesses should be made based on the calculation results of proposed decision model .
